Increasing waste generation worldwide has led the governments of all nations to leverage technological solutions for optimizing waste-to-energy processes.

FREMONT, CA: It is challenging to meet the rising demand for energy using a mix of conventional and renewable resources. Urban garbage accumulation is a problem practically everywhere globally that coexists with energy issues and is now reaching critical levels. Approximately 18 billion tonnes of garbage will be generated in the upcoming years due to population growth, lifestyle changes, and consumer habits. Ironically, most waste is burned carelessly near highways or open fields.

Over 130 million tonnes of municipal solid waste (MSW) are burned annually at over 600 waste-to-energy (WTE) facilities to create electricity, steam for district heating, and recycled metals. Globally, the waste-to-energy market is anticipated to reach USD 29.2 billion. The most popular waste-to-energy technique used globally is incineration with energy recovery.

Due to increased interest worldwide in integrated waste management frameworks in metropolitan areas, advanced thermal technologies, such as gasification and pyrolysis, and anaerobic digestion systems, are starting to make significant inroads in the waste-to-energy industry. Policy-makers, urban planners, entrepreneurs, utility companies, etc., are all showing a lot of interest in energy-from-waste systems due to the lack of disposal locations, expanding trash volumes, and issues with solid waste management.

The European countries are currently acknowledged as world leaders in the waste-to-energy trend. North America and the Asia-Pacific area come after them, respectively. Over 600 WTE plants were operational in 35 countries in 2007, including big nations like China and little ones like Bermuda. Asia is home to some of the newest flora. Waste-to-energy installations are growing rapidly in China, and the country intends to build 125 new ones during the twelve five-year plan, which ends in 2015.

In WTE facilities, the US processes 14 percent of its garbage. On the other hand, Denmark processes 54 percent more trash than any other nation. Governmental legislative changes have resulted in significant advancements for the region's WTE business, the adoption of cutting-edge technology, and creative recycling strategies.
