WASTE MANAGEMENT
imitate the economies of developed nations . Bringing WTE plants to these markets remains a challenge .
So how can it be managed ? The concept of WTE treats MSW not as a waste , but as a valuable resource and energy source . From 2011 to 2012 alone , capital and corporate investment in WTE projects nearly doubled . Unlike other energy sources , WTE is sold to plant operators at negative cost , eliminating material expenses . Although the industry has made great strides in efficiency since its inception , many challenges remain . New research aims to improve processing of mixed-material MSW , improve the design of processing plants , and further reduce plant emissions .

The Waste Incineration Process WTE plants can process waste energy in several ways :
• Production and distribution via grid systems
• Heat generation and distribution
• Biofuel extraction and refining
Worldwide WTE plants mainly operate using a hybrid of heat and power plants , better known as incineration . The process and controls vary based on the type of waste , cost limitations , and local temperature . A typical incineration process is as follows : 1 . Waste enters a bunker , is extracted and processed on a mobile grate . 2 . The waste may undergo treatment depending on its makeup and incineration method . 3 . Flue gases cycle heat in a boiler system to produce energy . The boiler type depends on the desired use of the converted energy .
