Abstract [en]

Around former glass factories in south eastern Sweden, there are dozens of dumps whose radioactivity and physico-chemical properties were not investigated previously. Thus, radiometric and physico-chemical characteristics of waste at Madesjö glass dump were studied to evaluate pre-recycling storage requirements and potential radiological and environmental risks. The material was sieved, hand-sorted, leached and scanned with X-Ray Fluorescence (XRF). External dose rates and activity concentrations of Naturally Occurring Radioactive Materials from 238U, 232Th series and 40K were also measured coupled with a radiological risk assessment. Results showed that the waste was 95% glass and dominated by fine fractions (< 11.3 mm) at 43.6%. The fine fraction had pH 7.8, 2.6% moisture content, 123 mg kg-1 Total Dissolved Solids, 37.2 mg kg-1 Dissolved Organic Carbon and 10.5 mg kg-1 fluorides. Compared with Swedish EPA guidelines, the elements As, Cd, Pb and Zn were in hazardous concentrations while Pb leached more than the limits for inert and non-hazardous wastes. With 40K activity concentration up to 3000 Bq kg-1, enhanced external dose rates of 40K were established (0.20 mSv h-1) although no radiological risk was found since both External Hazard Index (Hex) and Gamma Index (Iγ) were < 1. The glass dump needs remediation and storage of the waste materials under a safe hazardous waste class ‘Bank Account’ storage cell as a secondary resource for potential future recycling.

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).

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.

Abstract [en]

Landfill mining was introduced in research inSweden for more than three and a half decades ago. During recent years, thefocus has been on the glass dumps in the Kingdom of Crystal in southeasternSweden. Mapping of the dumps, test excavations, sieving and sorting of theglass masses, characterization, laboratory extraction of the metals in theglass was performed as well as measurements of radioactivity done. The pollutedsoil underneath the removed glass masses was treated by remediation. In one ofplaces at the kingdom of Glass a phytoremediation/tourist park was establishedin Orrefors including a summer glasswork for tourist activities.

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.

Abstract [en]

More than 34 old glasswork sites in the southeastern part of Sweden pose a permanent threat to human and environmental health due to the presence of toxic trace elements in open dumps with glass waste. The possibility of leaching of trace elements from different fractions of the disposed waste needed to be assessed. In the present investigation, leachate from a mixture of soil and waste glass of particle sizes of less than 2mm (given the name fine fraction) was characterized by analyzing the pH (7.3), total organic content (TOC<2%), organic matter content (4.4%), moisture content (9.7%), chemical oxygen demand (COD, 163mg/kg) and trace elements content, being the values in accordance to the Swedish guidelines for landfilling of inert materials. However, very high trace elements content was found in the fine fraction as well as in all colors of waste glass, whose values were compatible to hazardous waste landfill class. Tests with Lepidium sativum growing in the fine fraction as substrate revealed chronic toxicity expressed as inhibition of root biomass growth in 11 out of 15 samples. Additionally, leachate from fine fractions posed acute toxicity to genetically modified E. coli (Toxi-Chromotest). This study highlights the importance of combining physicochemical characterization with toxicity tests for both solid waste and leachate obtained from different waste fractions for proper hazardousness assessment supporting decision making on remediation demands.

Abstract [en]

Physico-chemical characteristics of waste, particularly fine fraction (FF), from an old crystal glass waste dump in Sweden were studied to assess recycling or disposal alternatives. Hand-sorting of the waste indicated glass content of 44.1% while sieving established the FF as a more soil-like mix of glass and other materials constituting 33.3% of all excavated waste. The FF was around neutral pH with 24.4% moisture content, low values of Total Dissolved Solids, Dissolved Organic Carbon and fluorides, but hazardous concentrations of As, Cd, Pb and Zn according to the Swedish Environmental Protection Agency guidelines. While the FF leached metals in low concentrations at neutral pH, it leached considerably during digestion with nitric acid, implying leaching risks at low pH. Thus, the waste requires safe storage in hazardous waste class ‘bank account’ storage cells to avoid environmental contamination as metal recovery and other recycling strategies for the glass waste are being developed. The study could fill the information gap regarding preservation of potential resources in the on-going, fast-paced excavation and re-landfilling of heavy metal contaminated materials in the region.

Abstract [en]

Dredging activities are necessary to maintain the navigation depth of harbors and channels. Additionally,dredging can prevent the loss of water bodies. A large amount of extracted sediments is produced around theworld. Removed material is widely disposed at open seas or landfills. Much of the dredged material is pollutedand is classified as unsuitable for open-sea disposal. In Sweden, many dredging activities are taking placenowadays like that in Oskarshamn harbor, Inre harbor Norrköping municipality and Malmfjärden bay inKalmar. In this review, the potential of phytoremediation as a treatment method is discussed with focus onsuggested methods for reusing the treated sediments. Recycling or reusing of dredged and treated sedimentswill preserve Earth natural resources as well as reduce diffusion of contaminants to the environment.

Abstract [en]

Coffee flour (CF) from coffee pulp or husk, solid waste of coffee processing have launched in Canada since 2015. This product is claimed as certified of gluten-free, vegan, kosher, paleo, and non-GMO. Coffe flour is stated to contain three times Fe content than fresh spinach (Spinacia oleracea L.). Several receipts of cookies, donuts, and cakes using CF has been introduced as wheat flour substitution. However, the scientific publication of CF impact for health does not appear until August 2018 yet. A review has been carried out using data on Google with a maximum publication age of 15 yr. This Fe non-heme prospect is allegedly unable to be absorbed optimally by the organism. Coffee pulp and husk contain an inhibitor, such as caffeine, polyphenol, calcium, dietary fiber, manganese, magnesium, and zinc; which detain Fe absorption. On the other hand, the promoter/enhancer of Fe absorption such as vitamin C, vitamin A, and amino acid was decreased in CF processing. Several types of research have to be conducted to tackle this problem in Faculty of Medicine and Faculty of Agriculture and Animal Husbandry University Muhammadyah of Malang, Indonesia.

Abstract [en]

Drinking water of good quality, in enough quantity at right time start to be very scarce in the world. At the same time perfect drinking water is used to flushing toilet, cleansing of sewage pipes, washing of industry floors, firefighting, washing of cars and trucks etc. Also agriculture is suffering of lack of water for irrigation during dry periods and it is necessary to use drinking water or river/lake water of high quality to get rich harvest of good quality. In the future drinking water must just be used as food stuff and not wasted in the society. People must, since they are children, be trained to respect the drinking water and not waste a single drop. Also, storm water can be considered as a source of fresh water if it collected and recycled properly. Recycling/reuse of treated/reclaimed wastewater will help to mitigate part of the increasing water demands in the society and secondary water can be used in non-potable end paths such as agriculture, industry or even recharging water aquifers.  Reclaimed/technical or recycled water for non-potable uses such as flushing toilets, irrigation and other uses will be very important in modern society in the future.
