Household waste arriving at Biotrend’s Integrated Waste Management facilities is directed to the relevant units according to waste type and processed. Accordingly, household waste is directed to mechanical separation and material recovery facilities, park and garden waste to composting facilities, waste suitable for biofuel production after mechanical separation to anaerobic fermentation units, and waste suitable for energy recovery to RDF facilities. Industrial waste that may be accepted at sanitary landfill sites in accordance with the legislation, and waste that is not suitable for material and energy recovery after mechanical separation, are directed to sanitary landfill sites for disposal.
Adverse environmental effects are prevented through effective leachate and odour management on site. In this respect, site design and rainwater control are the most important factors in leachate management at sanitary landfill areas. To reduce the environmental impacts that sanitary landfill facilities may cause, the impermeable layer built at the base of the landfill enables the leachate seeping from the landfill to be collected, preventing the contamination of groundwater and surface water. In these sealed areas, leachate is collected through the drainage layer, accumulated in lagoons/settling ponds and conveyed to wastewater treatment plants.
To prevent the potential risks that leachate may pose to soil and groundwater, it is also very important to establish an effective leachate collection and drainage system at sanitary landfill facilities in addition to the natural impermeable layer. Biotrend carries out sanitary landfill activities in full compliance with national environmental legislation. Within the scope of the environmental impact assessments of sanitary landfill sites, factors such as landfill area design, ground impermeability, drainage systems and leachate collection are taken into account.
