what are all the recent techniques available in solid waste management?
Some of the recent techniques in waste management include 1. Collection of methane gas from landfill. Gas is pumped out of the landfill using perforated pipes and flared off or burnt in a gas engine to generate electricity. 2. Biological processing which include composting and vermi composting. 3. Waste to energy – The energy content of waste products can be harnessed directly by using them as a direct combustion fuel, or indirectly by processing them into another type of fuel. Recycling through thermal treatment ranges from using waste as a fuel source for cooking or heating, to fuel for boilers to generate steam and electricity in a turbine. Pyrolysis and gasification are two related forms of thermal treatment where waste materials are heated to high temperatures with limited oxygen availability. The process typically occurs in a sealed vessel under high pressure. Pyrolysis of solid waste converts the material into solid, liquid and gas products. The liquid and gas can be burnt to pr
