Process flow chart. The terms mechanical biological treatment or mechanical biological pre-treatment relate to a group of solid waste treatment systems.These systems enable the recovery of materials contained within the mixed waste and facilitate the stabilisation of the biodegradable component of the material.
Plasma torch gasification is used commercially for waste disposal [30] at five sites worldwide with a combined design capacity of 200 tonnes of waste per day, half of which is biomass waste. Energy recovery from waste streams using plasma gasification is used in one or two installations treating 25-30 tonnes per day.
Pneumatic waste collection systems provide a number of environmental benefits. These systems can decrease emissions from transit of waste by up to 90%. [5] Systems in Europe provide separate outlets for food, recycling, and non-recycling, making waste separation and recycling more efficient.
Continuous use of various waste-derived alternative fuels then followed in the mid-1980s with “Brennstoff aus Müll“ (BRAM) – fuel from waste – in the Westphalian cement industry in Germany. At that time the thought of cost reduction through replacement of fossil fuels was the priority as considerable competition pressure weighed down ...
