Because waste is also an energy carrier and source of feedstocks, we focus on the best possible utilization of its energy and recoverable materials content. To ensure optimal resources recovery from waste and its ultimate disposal, we plan thermal and mechanical-biological waste treatment plants. Environmentally sound landfilling is the final link in the disposal chain.
Since the start of the 1960s, our engineers have investigated, engineered, tendered for, and supervised realization and rehabilitation of facilities for waste transfer; biological treatment, i.e. composting and anaerobic digestion; waste sorting; thermal treatment; and landfilling for all waste categories, starting with classical municipal solid waste through sewage sludge and up to hazardous waste.
As well as conventional plants for waste treatment, on the basis of refuse derived fuel (RDF), Fichtner plans facilities for supplying power, steam and heat to industry and communities. For thermal treatment in combined heat and power and industrial power plants or also waste-to-energy (WTE) plants, finding application are stoker-fired and fluidized bed furnaces as well as gasification (plasma gasification) and pyrolysis.
Our landfill planning ranges from the conventional reactor landfill to special-purpose landfills for treated waste streams. To protect soils and water resources, we implement systems for leachate collection and treatment as well as for landfill gas extraction.
