Historical pollution with hexachlorocyclohexane (HCH) isomers of soil and groundwater unfortunately is an unsolved problem, especially in some countries where Lindane is still produced, as also in Europe in the surrounding areas of former production sites or landfilling sites usually due to inadequate long-term storage, treatment or recovery of these wastes. HCH removal technologies are usually dedicated to soil remediation, leachate treatment, water and wastewater treatment. This paper presents the research effor...

Composting municipal organic waste is important for several reasons, including greenhouse gas emissions reduction, soil health improvement, nutrients recycle, waste reduction, costs reduction (by reducing the waste volumes, the handling costs are decreased). Information on the practices of municipal organic waste composting in Romania is limited, thus a comprehensive evaluation of the limiting factors and current solution was carried out. According to the European Environment Agency, Romania has made progress in o...

Compliance with EU environmental regulations and directives regarding effluent water quality discharged is seen as the main driver for the development of wastewater treatment technologies. The Water Framework Directive, the UWWT Directive, and the Nitrates Directive require the reduction of eutrophication caused by nitrogen and phosphorus emissions. In Romania, only approx. 54% of the population is connected to centralized sewage and wastewater treatment systems, meaning that approximately 8 million inhabitants ar...

Organic contaminants such as total pe troleum hydrocarbons, including aliphatic hydrocarbons, polycyclic aromatic hydrocarbon s and BTEX are recognized as one of the predominant pollutants within Romanian contaminated sites. This study presents a set of experiments for the remediation of a soil contaminated accidentally with petroleum products conducted in slurry-type batch systems, designed to establish the best remediation approach. The experime ntal variants consisted in biological remediation (natural attenuat...
