Among the registered landfill gas capture projects that are operating , and the World Bank is a trustee for a Commercial Fund , are projects in Alexandria , Egypt , Durban South Africa , Monterrey Mexico , Montevideo Uruguay , Nova Iguacu Brazil , and Tianjin China . The World Bank Group offers investors a wide variety of financial commercial products , investment business opportunities , that range from AAA – rated technical products , such as discounts business notes and benchmark bonds , to more than 100 emerging nation market managed commercial funds with a combined technical commitment value of USD $ 1 Billion .
Tianjin , with a population of about 9.6 million , is the third largest city in China , about 150 kilometers from Beijing . The city is served by a network of disposal sites that includes four landfills and an incinerator . Effective solid waste management is a major concern for cities in most emerging economies nations . Why should we be aware of this ?
· Current disposal practices in cities are by sanitary landfill or open dumping
· Existing dumpsites in most cities are getting saturated and causing health concerns
· With land shortages , finding new sites is getting difficult
· People object to having sanitary landfill sites near them
· Trash in a landfill doesn’t break down as there is little oxygen or moisture inside .
The gas capture and use program developed by the Tianjin Clean Energy and Environmental Engineering Co. Ltd. ( TCEEE ) , is a joint undertaking of the Tianjin Construction Commission and the Environmental Sanitation Commission .
About 2 Million tons of wastes have been received at the landfill and 34 horizontal collection wells have been installed on about four hectares of the site . The landfill gas captured is being drawn to an energy recovery center where one Caterpillar Combustion generator with a total generating capacity of 1.03 MW is being used to generate electricity for sale to the power grid . This is an alternative for the Government of the Republic People of China in seeking to reduce both the cost of electricity supply and China’s vulnerability to oil and charcoal price shocks . The initial screening shows that landfill gas utilization offers the least cost option at lifecycle cost of China Energy Commission ( CEC ) 0.2 per kWh . Replacing 30% of China’s diesel and charcoal used for power generation following a least – cost development plan requires a combination of various projects .
The emission reduction methodologies applied to this project were ACM 0001 ( Consolidated base line and monitoring for landfill gas projects activities ) and AMS – I.D. ( Grid connected renewable electricity generation ) .
