Solid waste management
Solid waste management is
more than just a combination of different treatment and
disposal techniques. Master planning and feasibility
studies should result in an environmentally sound approach
and implementation matching the financial and institutional
possibilities. To minimize the environmental impact of
solid waste, alternatives for prevention, collection,
processing, reuse and final disposal have to be assessed
carefully. These activities should appreciate public
awareness, organizational framework, administrative
structure, legislation, available technologies, available
land, environmental objectives and financial resources.
Sanitary landfilling
Sanitary landfilling is a
widely applied cost effective method of solid waste
disposal. To minimize the environmental impact the design,
planning and operation of landfills needs to anticipate the
emission control requirements. WWE is active in emission
control of leachate water and landfill gas.
Landfill gas extraction
Under normal conditions
organic refuse present in a landfill will be converted by
bacteria to landfill gas (CH4, CO2). The extraction of this
gas can provide a considerable energy source, while the
emission of malodorous gas has to be controlled. WWE has
extensive experience with landfill gas migration research,
extraction (gas wells and compressors) and utilization.
