This investigation has established the possibility of producing Particleboard from Byrene (waste after the oil has been extracted from the second time with Naphtha). This product has good physical-[moisture content (6.1%). density (0.73). absorption and cross-swelling after 2 hours (29.8%:12.6%) and after 24 hours (40.1%:19.1%)] and mechanical properties [binding strength (8.3 N/mm2) and cross-tensile strength (0.23 N/mm2)] according to European Norms and is very economical.
