    Desafíos en la gestión de residuos sólidos para las ciudades de países en desarrollo [Solid waste management challenges for cities in developing countries]2015Ingår i: Tecnología en Marcha, ISSN 0379-3982, Vol. 28, nr 2, s. 141-168Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Solid waste management is a challenge for the cities' authorities in developing countries mainly due to the increasing generation of waste, the burden posed on the municipal budget as a result of the high costs associated to its management, the lack of understanding over a diversity of factors that affect the different stages of waste management and linkages necessary to enable the entire handling system functioning. An analysis of literature on the work done and reported mainly in publications from 2005 to 2011, related to waste management in developing countries, showed that few articles give quantitative information. The analysis was conducted in two of the major scientific journals, Waste Management Journal and Waste Management and Research. The objective of this research was to determine the stakeholders' action/behavior that have a role in the waste management process and to analyze influential factors on the system, in more than thirty urban areas in 22 developing countries in 4 continents. A combination of methods was used in this study in order to assess the stakeholders and the factors influencing the performance of waste management in the cities. Data was collected from scientific literature, existing data bases, observations made during visits to urban areas, structured interviews with relevant professionals, exercises provided to participants in workshops and a questionnaire applied to stakeholders. Descriptive and inferential statistic methods were used to draw conclusions. The outcomes of the research are a comprehensive list of stakeholders that are relevant in the waste management systems and a set of factors that reveal the most important causes for the systems' failure. The information provided is very useful when planning, changing or implementing waste management systems in cities.

    An overview of the modification methods of activated carbon for its water treatment applications2013Ingår i: Chemical Engineering Journal, ISSN 1385-8947, E-ISSN 1873-3212, Vol. 219, s. 499-511Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Activated carbon has been recognized as one of the oldest and widely used adsorbent for the water and wastewater treatment for removing organic and inorganic pollutants. The application of activated carbon in adsorption process is mainly depends on the surface chemistry and pore structure of porous carbons. The method of activation and the nature of precursor used greatly influences surface functional groups and pore structure of the activated carbon. Therefore, the main focus of researchers is to develop or modifies the activation/treatment techniques in an optimal manner using appropriate precursors for specific pollutants. In recent years, emphasis is given to prepare the surface modified carbons using different procedures to enhance the potential of activated carbon for specific contaminants. Various methods such as, acid treatment, base treatment, impregnation treatment, ozone treatment, surfactant treatment, plasma treatment and microwave treatment have been studied to develop surface modified activated carbons. In this paper, these modification methods have been reviewed and the potential of surface modified activated carbons towards water treatment has been discussed. This review article is aimed at providing precise information on efforts made by various researchers in the field of surface modification of activated carbon for water pollution control.

    Hunting for valuables from landfills and assessing their market opportunities: A case study with Kudjape landfill in Estonia2017Ingår i: Waste Management & Research, ISSN 0734-242X, E-ISSN 1096-3669, Vol. 35, nr 6, s. 627-635Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Landfill mining is an alternative technology that merges the ideas of material recycling and sustainable waste management. This paper reports a case study to estimate the value of landfilled materials and their respective market opportunities, based on a full-scale landfill mining project in Estonia. During the project, a dump site (Kudjape, Estonia) was excavated with the main objectives of extracting soil-like final cover material with the function of methane degradation. In total, about 57,777 m(3) of waste was processed, particularly the uppermost 10-year layer of waste. Manual sorting was performed in four test pits to determine the detailed composition of wastes. 11,610 kg of waste was screened on site, resulting in fine (<40 mm) and coarse (>40 mm) fractions with the share of 54% and 46%, respectively. Some portion of the fine fraction was sieved further to obtain a very fine grained fraction of <10 mm and analyzed for its potential for metals recovery. The average chemical composition of the <10 mm soil-like fraction suggests that it offers opportunities for metal (Cr, Cu, Ni, Pb, and Zn) extraction and recovery. The findings from this study highlight the importance of implementing best available site-specific technologies for on-site separation up to 10 mm grain size, and the importance of developing and implementing innovative extraction methods for materials recovery from soil-like fractions.

    Valorization of solid waste products from olive oil industry as potential adsorbents for water pollution control-a review2014Ingår i: Environmental science and pollution research international, ISSN 0944-1344, E-ISSN 1614-7499, Vol. 21, nr 1, s. 268-298Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    The global olive oil production for 2010 is estimated to be 2,881,500 metric tons. The European Union countries produce 78.5 % of the total olive oil, which stands for an average production of 2,136,000 tons. The worldwide consumption of olive oil increased of 78 % between 1990 and 2010. The increase in olive oil production implies a proportional increase in olive mill wastes. As a consequence of such increasing trend, olive mills are facing severe environmental problems due to lack of feasible and/or cost-effective solutions to olive-mill waste management. Therefore, immediate attention is required to find a proper way of management to deal with olive mill waste materials in order to minimize environmental pollution and associated health risks. One of the interesting uses of solid wastes generated from olive mills is to convert them as inexpensive adsorbents for water pollution control. In this review paper, an extensive list of adsorbents (prepared by utilizing different types of olive mill solid waste materials) from vast literature has been compiled, and their adsorption capacities for various aquatic pollutants removal are presented. Different physicochemical methods that have been used to convert olive mill solid wastes into efficient adsorbents have also been discussed. Characterization of olive-based adsorbents and adsorption mechanisms of various aquatic pollutants on these developed olive-based adsorbents have also been discussed in detail. Conclusions have been drawn from the literature reviewed, and suggestions for future research are proposed.

    Former dump sites and the landfill mining perspectives in baltic countries and Sweden: The status2013Ingår i: SGEM2013 Conference Proceedings, 2013, s. 485-492Konferensbidrag (Refereegranskat)
    Abstract [en]

    Landfills are considered as places where the life cycle of products ends thus meaning that resources and materials, which before were valuables, become useless and are disposed forever in places away from the sight. Landfills that were not closed appropriately are of primary importance as the EU legislation demands closure of noncompliant landfills, re-cultivation followed by soil and groundwater remediation. Waste dumps in former times were created without any environmental planning and it causes problems. Planned actions to reduce and prevent impacts to the environment and get extracted valuables from dump sites are proposed in a new approach known as "landfill mining" (LFM). The number of dumpsites which are still not appropriately closed according to the EU Directives has diminished, but not completely. Landfills that are located close to the Baltic Sea and Black Seas could be good candidates for LFM. This research topic has had evolved in many aspects with the interest increase on material recovery, refuse derived fuels (RDF) production, greenhouse gas and leachate emission diminishing. Real-time applied LFM in last decade in Sweden has started and Estonian scientists and entrepreneurs took over the initiative - the project in Saaremaa Island is an example of closing the life cycle of dumpsites by following a more sustainable approach. The rise of raw material and energy costs promotes the process of LFM to be economically feasible, but this approach must be adjusted in regulations (permittingprohibiting schemes, environmental impact assessment, staff safety, monitoring).

    Fluorescence Spectroscopy – Applied Tool for Organic Matter Analysis2019Ingår i: Goldschmidt Abstracts, 2019, 2019Konferensbidrag (Refereegranskat)
    Abstract [en]

    Large applied projects in various sub-fields of environmental science studied and analyzed properties of organic matter. The “Life-Sure” is as continuation of started work for cost effective bottom sediments treatment where organic matter play important role of sorption of urban contaminants; “CONTRA” - beach wrack studies for advanced value-based bioeconomy development. Another project on Jurassic clay is interesting in discourse on Pleistocene glaciers glaciodynamics. Material from field was tested by 3D fluorescence excitation-emission matrix (EEM) providing “fingerprints” for a single compound or a mixture of fluorescent components. Thus humic macromolecules might be well seen nevertheless structural units have variable effects on the wavelength as well as intensity of fluorescence. It decreases with increasing molecular size of the humic macromolecule. For applied environmental projects this is well non-destructive tool to quantify the decomposition degree of organic matter requiring negligible amount of sample. This important method is valid for both organic matter and humic substances analytics. Chemical nature of humic substances can be correlated to structural information, e.g., functional groups, poly-condensation, aromaticity, dynamic properties related to intermolecular interactions. Acquired data from EEM provided significant input for scientific knowledge and innovation along with other analytical tools.

    On the way to 'zero waste' management: Recovery potential of elements, including rare earth elements, from fine fraction of waste2018Ingår i: Journal of Cleaner Production, ISSN 0959-6526, E-ISSN 1879-1786, Vol. 186, s. 81-90Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Existing schemes of solid waste handling have been improved implementing advanced systems for recovery and reuse of various materials. Nowadays, the 'zero waste' concept is becoming more topical through the reduction of disposed waste. Recovery of metals, nutrients and other materials that can be returned to the material cycles still remain as a challenge for future. Landfill mining (LFM) is one of the approaches that can deal with former dumpsites, and derived materials may become important for circular economy within the concept 'beyond the zero waste'. Perspectives of material recovery can include recycling of critical industrial metals, including rare earth elements (REEs). The LFM projects performed in the Baltic Region along with a conventional source separation of iron-scrap, plastics etc. have shown that the potential of fine-grained fractions (including clay and colloidal matter) of excavated waste have considerably large amounts of potentially valuable metals and distinct REEs. In this paper analytical screening studies are discussed extending the understanding of element content in fine fraction of waste derived from excavated, separated and screened waste in a perspective of circular economy. Technological feasibility was evaluated by using modified sequential extraction technique where easy extractable amount of metals can be estimated. Results revealed that considerable concentrations of Mn (418-823 mg/kg), Ni (41-84 mg/kg), Co (10.7-19.3 mg/kg) and Cd (1.0-3.0 mg/kg) were detected in fine fraction (<10 mm) of waste sampled from Hogbytorp landfill, while Cr (49-518 mg/kg) and Pb (30-264 mg/kg) were found in fine fraction (<10 mm) of waste from Torma landfill revealing wide heterogeneity of tested samples. Waste should become a utilizable resource closing the loop of anthropogenic material cycle as the hidden potential of valuable materials in dumps is considerable. (C) 2018 Elsevier Ltd.

    Field-portable X-ray fluorescence spectrometry as rapid measurement tool for landfill mining operations: comparison of field data vs. laboratory analysis2015Ingår i: International Journal of Environmental Analytical Chemistry, ISSN 0306-7319, E-ISSN 1029-0397, Vol. 95, nr 7, s. 609-617Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Landfill mining applied in reclamation at the territories of old dump sites and landfills is a known approach tended to global economic and environmental benefits as recovery of metals and energy is an important challenge. The aim of this study was to analyse the concentration of several metallic elements (Ca, Cu, Cr, Fe, K, Mn, Pb, Zn) in the fine fraction of waste derived in the landfill and to compare the results of measurements obtained by field-portable equipment with the data gained by advanced analytical tools. Atomic absorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS) were used for the quantitative detection of metallic elements at the laboratory; whereas field-portable X-ray fluorescence spectrometry (FPXRF) was applied for rapid sample characterisation in the field (on-site). Wet digestion of samples (fine fraction of waste at landfill) was done prior analytical procedures at the laboratory conditions, but FPXRF analysis was performed using raw solid samples of waste fine fraction derived in the Kudjape Landfill in Estonia. Although the use of AAS and ICP-MS for the measurements of metals achieves more precise results, it was concluded that precision and accuracy of the measurements obtained by FPXRF is acceptable for fast approximate evaluation of quantities of metallic elements in fine fraction samples excavated from the waste at landfills. Precision and accuracy of the results provided by express method is acceptable for quick analysis or screening of the concentration of major and trace metallic elements in field projects; however, data correction can be applied by calculating moisture and organic matter content dependent on sample matrix as well as special attention must be paid on sample selection and homogenisation and number of analysed samples.

    Mobility of Metals and Valorization of Sorted Fine Fraction of Waste After Landfill Excavation2016Ingår i: Waste and Biomass Valorization, ISSN 1877-2641, E-ISSN 1877-265X, Vol. 7, nr 3, s. 593-602Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Reclamation of landfills and dumpsites requiresdetailed technical and economic evaluation of actual and potential pollution at the site, including detection of the main contaminants, their concentration, chemical stability and mobility in the environment. Contamination with metallic elements and metalloids is among the most important problems that limits recultivation of landfills and dumpsites and reuse of landfilled materials. This study was implemented at the Kudjape Municipal Landfill, located on Saaremaa Island in Estonia. The Kudjape Landfill is apartly closed landfill recultivated by covering it with a layer of a fine fraction of landfill material after the landfill mining operations. The fine fraction was derived at the site by sorting the landfill material (i.e., disposed waste) using mechanical screening, manual sorting and sieving. Obtained relatively homogeneous material, consisting of particles smaller than 10 mm, was defined as a fine fractionof waste. Samples from the fine fraction at different depth were collected and analyzed. Metal mobility was assessed after the sequential extraction. Results revealed that such elements as Zn, Mn, Mg are found in various fractions; Fe,Cd, Cr—mainly in residual fraction; Cu, Pb, Ni, Ba, Co and Rb mostly in fractions of residuals and reduced compounds,but they are presented in larger proportion of acid and water soluble fractions. Slight interconnection ofdetected parameters and sampling depth was revealed. Sequential extraction of elements in the fine fraction suggested the valorization of waste and confirmed that such landfill material can be successfully used as a landfill covering layer under the specific engineering circumstances.

    Metals and rare Earth’s elements in landfills: case studies2016Ingår i: 3rd Int. Symposium on Enhanced Landfill Mining, Lisboa, 8-10/2/2016, 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    Landfills are considered as places where the life cycle of products ends and materialshave been “disposed forever”. The landfill mining (LFM) approach can deal with formerdumpsites and this material may become important for circular economy perspectiveswithin the concept “Beyond the zero waste”. Potential material recovery should includeperspectives of recycling of critical industrial metals where rare Earth elements (REEs)are playing more and more important role. Real-time applied LFM projects in the BalticRegion have shown the potential of fine-grained fractions (including clay and colloidalmatter) of excavated waste as storage of considerably large amounts of valuable metalsand REEs. Analytical screening studies have extended a bit further the understanding offine fraction contents of excavated, separated and screened waste in a circular economyperspective. The Swedish Institute and Latvian Research Program “Res Prod” supportedthe research.

    Paradigms on landfill mining: From dump site scavenging to ecosystem services revitalization2017Ingår i: Resources, Conservation and Recycling, ISSN 0921-3449, E-ISSN 1879-0658, Vol. 123, s. 73-84Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    For the next century to come, one of the biggest challenges is to provide the mankind with relevant and sufficient resources. Recovery of secondary resources plays a significant role. Industrial processes developed to regain minerals for commodity production in a circular economy become ever more important in the European Union and worldwide. Landfill mining (LFM) constitutes an important technological toolset of processes that regain resources and redistribute them with an accompanying reduction of hazardous influence of environmental contamination and other threats for human health hidden in former dump sites and landfills. This review paper is devoted to LFM problems, historical development and driving paradigms of LFM from 'classical hunting for valuables' to 'perspective in ecosystem revitalization'. The main goal is to provide a description of historical experience and link it to more advanced concept of a circular economy. The challenge is to adapt the existing knowledge to make decisions in accordance with both, economic feasibility and ecosystems revitalization aspects. (C) 2016 Elsevier B.V. All rights reserved.

    Gateway of Landfilled Plastic Waste Towards Circular Economy in Europe2019Ingår i: Separations, E-ISSN 2297-8739, Vol. 6, nr 2, s. 1-8, artikel-id 25Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    For decades, significant work has been conducted regarding plastic waste by dealing with rejected materials in waste masses through their accumulation, sorting and recycling. Important political and technical challenges are involved, especially with respect to landfilled waste. Plastic is popular and, notwithstanding decrease policies, it will remain a material widely used in most economic sectors. However, questions of plastic waste recycling in the contemporary world cannot be solved without knowing the material, which can be achieved by careful sampling, analysis and quantification. Plastic is heterogeneous, but usually all plastic waste is jointly handled for recycling and incineration. Separation before processing waste through the analytical approach must be applied. Modern landfill mining and site clean-up projects in contemporary waste management systems require comprehensive material studies ranging from the macro-characterization of waste masses to a more detailed analysis of hazardous constituents and properties from an energy calorific standpoint-where, among other methods, thermogravimetric research coupled with life cycle assessment (LCA) and economic assessment is highly welcomed.

    Remarks on novel case studies for integrated pollution prevention in the baltic sea region2018Ingår i: International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM, International Multidisciplinary Scientific GeoConference & EXPO SGEM , 2018, nr 3.2, s. 1167-1174Konferensbidrag (Refereegranskat)
    Abstract [en]

    The Baltic Sea is suffering from extended surplus of phosphorus, nitrogen and other pollutants. It causes diminishing biodiversity and increased eutrophication (mainly due to nitrogen and phosphorous in various substances). The common effort in the region is environmental standpoint in sustainable circular economy. Oil pollutants, heavy metals, organic substances are being released to the Baltic Sea and consequences for maritime environment are serious. However, Baltic Sea Region is one of the most innovative regions in the world considering environmental technology development. The interregional potential is about to solve the above mentioned challenges there were developed the project “Reviving Baltic Resilience (RBR)”. By using prior experiences in other EU projects as well as continuously working and acquiring new data and knowledge, our aim is to test at proactive methods/technologies for preventing pollution reaching the maritime environment and entering biological chains. The paper focuses on three novel case studies: 1) pollution prevention through phytoremediation at landfill close to the sea; 2) studies on sludge deposits with focus on recovery potential; 3) prevention of release of pollutants from sediments in bays and lagoons. This project was supported by Interreg South Baltic program “Reviving Baltic Resilience” (RBR) and Swedish Institute “PECEC”. © SGEM 2018.

    Effects of single and mixed estrogens on single and combined cultures of D. subspicatus and P. subcapitata2014Ingår i: Bulletin of Environmental Contamination and Toxicology, ISSN 0007-4861, E-ISSN 1432-0800, Vol. 93, nr 2, s. 215-221Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper investigates the effect of estrone (E1), 17 beta-estradiol (E2) and 17 alpha-ethinylestradiol (EE2) individually and mixed at equal proportions (1:1:1) on Desmodesmus subspicatus and Pseudokirchneriella subcapitata in single and combined cultures (S+) at different exposure times basedon algal growth (in vivo chlorophyll fluorescence and cell counting) and coenobium formation. EE2 and E2 were more toxic to individual and combined (S+) cultures than was E1. The frequency of coenobium formation by D. subspicatus increased significantly for all estrogens and all concentrations. After 96 h, D. subspicatus prevailed in S+. The results of the exposure to E+ suggested a less-than-additive effecton D. subspicatus and S+ and additive effect on P. subcapitata. Toxic effects occurred for both species exposed to E+ with individual estrogen concentrations below the NOEC of each species. Assays must include changes in response due to the exposure of more than one species to more than one estrogen.

    Significance of environmental dredging on metal mobility from contaminated sediments in the Oskarshamn Harbor, Sweden2015Ingår i: Chemosphere, ISSN 0045-6535, E-ISSN 1879-1298, Vol. 119, s. 445-451Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Metals are often seen as immobile in bottom sediments as long as these environmental sinks remain undisturbed. The aim of this paper was to evaluate the potential metal mobility due to resuspension under pseudo-dredging conditions of contaminated sediments in the Oskarshamn Harbor that are likely to be dredged as part of a remediation program established in Sweden. To address this concern, mixtures of water slurries were sampled from pore, leaching, and surface water over a period of nearly 36 d, and the major ions and trace metal concentrations determined. The results of this study pointed out the potential mobility and toxicity of metals posed by temporary changes during dredging operations, and highlighted the potential release of Cu, Pb, Zn, Mn, and Ni to the environment. Among the toxic metals, regarding pre and post dredging, Cu and Pb significantly demonstrated to be in ionic form, apparently because of dissolution of Fe-Mn oxy/hydroxides and decomposition of organic matter.

    Speciation of metals in contaminated sediments from Oskarshamn Harbor, Oskarshamn, Sweden2014Ingår i: Environmental science and pollution research international, ISSN 0944-1344, E-ISSN 1614-7499, Vol. 21, nr 4, s. 2455-2464Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Bottom sediments in coastal regions have been considered the ultimate sink for a number of contaminants, e. g., toxic metals. In this current study, speciation of metals in contaminated sediments of Oskarshamn harbor in the southeast of Sweden was performed in order to evaluate metal contents and their potential mobility and bioavailability. Sediment speciation was carried out by the sequential extraction BCR procedure for As, Cd, Cr, Cu, Hg, Ni, Pb, and Zn and the exchangeable (F1), reducible (F2), oxidizable (F3), and residual (R) fractions were determined. The results have shown that Zn and Cd were highly associated with the exchangeable fraction (F1) with 42-58 % and 43-46 %, respectively, of their total concentrations in the mobile phase. The assessment of sediment contamination on the basis of quality guidelines established by the Swedish Environmental Protection Agency (SEPA) and the Italian Ministry of Environment (Venice protocol for dredged sediments) has shown that sediments from Oskarshamn harbor are highly contaminated with toxic metals, especially Cu, Cd, Pb, Hg, As, and Zn posing potential ecological risks. Therefore, it is of crucial importance the implementation of adequate strategies to tackle contaminated sediments in coastal regions all over the world.

    Characterization of dredged sediments: a first guide to define potentially valuable compounds - the case of Malmfjärden Bay, Sweden2019Ingår i: Advances in Geosciences, ISSN 1680-7340, E-ISSN 1680-7359, Vol. 49, s. 137-147Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Millions of tons of bottom sediments are dredged annually all over the world. Ports and bays need to extract the sediments to guarantee the navigation levels or remediate the aquatic ecosystem. The removed material is commonly disposed of in open oceans or landfills. These disposal methods are not in line with circular-economy goals and additionally are unsuitable due to their legal and environmental compatibility. Recovery of valuables represents a way to eliminate dumping and contributes towards the sustainable extraction of secondary raw materials. Nevertheless, the recovery varies on a case-by-case basis and depends on the sediment components. Therefore, the first step is to analyse and identify the sediment composition and properties. Malmfjärden is a shallow semi-enclosed bay located in Kalmar, Sweden. Dredging of sediments is required to recuperate the water level. This study focuses on characterizing the sediments, pore water and surface water from the bay to uncover possible sediment recovery paths and define the baseline of contamination in the water body. The results showed that the bay had high amounts of nitrogen (170–450 µg L−1 ), leading to eutrophication problems. The sediments mainly comprised small size particle material (silt, clay and sand proportions of 62 %–79 %, 14 %–20 %, 7 %–17 %, respectively) and had a medium–high level of nitrogen (7400–11 000 mg kg−1 ). Additionally, the sediments had little presence of organic pollutants and low–medium concentration of metals or metalloids. The characterization of the sediments displays a potential use in less sensitive lands such as in industrial and commercial areas where the sediments can be employed as construction material or as plant-growing substrate (for ornamental gardens or vegetation beside roads).

    Solid waste management challenges for cities in developing countries2013Ingår i: Waste Management, ISSN 0956-053X, E-ISSN 1879-2456, Vol. 33, nr 1, s. 220-232Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Solid waste management is a challenge for the cities' authorities in developing countries mainly due to the increasing generation of waste, the burden posed on the municipal budget as a result of the high costs associated to its management, the lack of understanding over a diversity of factors that affect the different stages of waste management and linkages necessary to enable the entire handling system functioning. An analysis of literature on the work done and reported mainly in publications from 2005 to 2011, related to waste management in developing countries, showed that few articles give quantitative information. The analysis was conducted in two of the major scientific journals, Waste Management Journal and Waste Management and Research. The objective of this research was to determine the stakeholders' action/behavior that have a role in the waste management process and to analyze influential factors on the system, in more than thirty urban areas in 22 developing countries in 4 continents. A combination of methods was used in this study in order to assess the stakeholders and the factors influencing the performance of waste management in the cities. Data was collected from scientific literature, existing data bases, observations made during visits to urban areas, structured interviews with relevant professionals, exercises provided to participants in workshops and a questionnaire applied to stakeholders. Descriptive and inferential statistic methods were used to draw conclusions. The outcomes of the research are a comprehensive list of stakeholders that are relevant in the waste management systems and a set of factors that reveal the most important causes for the systems' failure. The information provided is very useful when planning, changing or implementing waste management systems in cities. (c) 2012 Elsevier Ltd. All rights reserved.

    Advanced Oxidation Treatment of Recalcitrant Wastewater from a Wood-Based Industry: a Comparative Study of O3 and O3/UV2015Ingår i: Water, Air and Soil Pollution, ISSN 0049-6979, E-ISSN 1573-2932, Vol. 226, nr 7, artikel-id 229Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Ozone and ozone-based advanced oxidation processes were applied for the treatment of a recalcitrant wastewater generated by wood-based industries that contains different inorganic and organic constituents and high chemical oxygen demand (COD) varying between 3,400 and 4,000 mg/L. The investigation used a tubular ozone reactor combined with an UV reactor designed for different hydraulic retention times. The dependent variables addressed to evaluate the treatment efficiency were the reduction of COD and total organic carbon (TOC) and the biodegradability of the treated effluent based on respirometric studies using activated sludge from a wastewater treatment. The results showed that even though ozonation alone at acid pH promoted COD and TOC reductions of 65 and 31 % respectively, a decrease in the biodegradability was observed. The most effective treatment (COD and TOC reductions of 93 and 43 %, respectively) was obtained when applying ozone combined with UV light at basic pH. The ozone-UV combination was capable of increasing the amount of readily available COD by 75 % with an additional reduction of TOC by 60 %. In conclusion, ozonation at low pH effectively reduces the COD content in wastewater generated by the wood-based industry; however, in order to combine advanced oxidation with biological process, ozone combined with UV is recommended.

    Photo-Fenton and Fenton Oxidation of Recalcitrant Industrial Wastewater Using Nanoscale Zero-Valent Iron2012Ingår i: International Journal of Photoenergy (Online), ISSN 1110-662X, E-ISSN 1687-529X, Vol. 2012, artikel-id 531076Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There is a need for the development of on-site wastewater treatment technologies suitable for "dry-process industries," such as the wood-floor sector. Due to the nature of their activities, these industries generate lower volumes of highly polluted wastewaters after cleaning activities. Advanced oxidation processes such as Fenton and photo-Fenton, are potentially feasible options for treatment of these wastewaters. One of the disadvantages of the Fenton process is the formation of large amounts of ferrous iron sludge, a constraint that might be overcome with the use of nanoscale zero-valent iron (nZVI) powder. Wastewater from a wood-floor industry with initial COD of 4956 mg/L and TOC of 2730 mg/L was treated with dark-Fenton (nZVI/H2O2) and photo-Fenton (nZVI/H2O2/UV) applying a 2-level full-factorial experimental design. The highest removal of COD and TOC (80% and 60%, resp.) was achieved using photo-Fenton. The supply of the reactants in more than one dose during the reaction time had significant and positive effects on the treatment efficiency. According to the results, Fenton and mostly photo-Fenton are promising treatment options for these highly recalcitrant wastewaters. Future investigations should focus on optimizing treatment processes and assessing toxic effects that residual pollutants and the nZVI might have. The feasibility of combining advanced oxidation processes with biological treatment is also recommended.

    Photo-Fenton and Fenton Oxidation of Recalcitrant Wastewater from the Wooden Floor Industry2015Ingår i: Water environment research, ISSN 1061-4303, E-ISSN 1554-7531, Vol. 87, nr 6, s. 491-497Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There is a need for development of on-site wastewater treatment technologies suitable to "dry-process'' industries, such as the wooden floor sector. Due to the nature of their activities, these industries generate low volumes of highly polluted and recalcitrant wastewaters due to washing and cleaning surfaces and machinery. Advanced oxidation processes such as Fenton and photo-Fenton are potentially feasible options for the treatment of wastewaters with not easily biodegradable pollutants. The wastewater from a wooden floor industry with initial COD value of 4956 mg/L and TOC value of 2730 mg/L was treated with Fenton (Fe/H2O2) and photo-Fenton (Fe/H2O2/UV) applying a 2-level full-factorial experimental design. The highest removals of COD and TOC (79% and 62% respectively) were achieved when photo-Fenton was applied. In conclusion, Fenton and photo-Fenton are promising treatment options for these highly recalcitrant wastewaters, photo-Fenton being a more promising option according to the results.

    Electrocoagulation coupled to activated carbon sorption/filtration for treatment of cleaning wastewaters from wood-based industry2014Ingår i: Desalination and Water Treatment, ISSN 1944-3994, E-ISSN 1944-3986, Vol. 52, nr 28-30, s. 5243-5251Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The objective of this investigation was to study the use of a coupled treatment (electrocoagulation(EC) and sorption/filtration treatment) with different sequencing to reduce the organic pollutantsmeasured as chemical oxygen demand (COD) of five highly polluted wastewater streamsgenerated after washing surfaces and machinery in the wooden floor industry and to evaluate,how different sequencing of these treatment units affects the overall system efficiency. On thebasis of preliminary studies, an EC reactor (1.0 L) was constructed with monopolar electrodes inparallel connection in an array of four Al electrodes with surface area of 93.2 cm2and an appliedcurrent density of 161 A m–2. This reactor was coupled to a sorption/filtration unit with coalactivated carbon. The EC reactor was tested in two different sequences (before and after the sorption/filtration unit). The overall COD reduction varied from 2% ± 0.5% to 77% ± 2.9%, dependingon the sequence and the treated wastewater stream. The best result from efficiency andoperational viewpoints was obtained with the EC reactor placed after the sorption/filtrationcolumn. The increase in efficiency is likely to be due to the removal by sorption in the activatedcarbon of compounds that interfere with EC. Additionally, as desired, the use of EC before thesorption unit extended the activated carbon lifetime.
