One of the main challenges in treating landfill leachate through membranes is managing the resulting concentrate. Depending on the membrane installation's performance and the stored waste's characteristics, significant quantities of concentrate may remain after leachate treatment. Therefore, it is necessary to identify an optimal disposal or treatment method for it. In the European Union List of Waste, the membrane concentrates are associated with leachates and are classified as either hazardous or non-hazardous w...

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...
