In the recent National Development and Reform Commission for the plastic garbage pollution control public solicitation opinions, the zero waste coalition of environmental organizations to the National Development and Reform Commission advice: stop plastic waste incineration of renewable energy subsidies.
Mao Zedong, founder of Zero Waste Alliance, said the current MSW subsidy standards give policy support to all incineration plant waste as "biomass energy." However, it also includes a large amount of plastic waste, mainly from Fossil fuels, not biomass waste, should not be included in the scope of renewable energy.
According to estimates, the Zero Waste Alliance proposed that "a large part of the tariff subsidies originally intended to support biomass-based renewable energy sources are mistakenly added to the part of plastic waste incineration."
Maoda believes that the timely correction of plastic waste incineration fault problem, can strongly promote the source of plastic waste reduction and recycling.
'Plastic garbage is not a renewable energy source,' and Mao Tau specifically explained the relationship between domestic waste, biomass waste and biomass energy.
As a complex solid waste mixture, household waste generally includes light combustibles (such as plastic, paper, leaves, etc., which are lighter in mass and higher in calorific value), kitchen waste (such as peels, leftovers, etc.) Large amount of water) and metal, glass and other general non-combustible inorganic substances.
According to the report "Management Objectives and Management Modes for Urban Domestic Waste in China in the Thirteenth Five-year Plan" issued by the National Institute of Development and Strategy of Renmin University of China in 2015, Maoda said that in 11 cities across the country (including Beijing, Tianjin and Shanghai), plastics The proportion of the total amount of waste accounted for about 12% of the average.
As early as 2006, the National Development and Reform Commission released two normative documents, "Provisional Measures for the Management of Prices and Expenses Allocation of Renewable Energy Power Generation," and "Provisions on Relevant Management of Renewable Energy Generation," explicitly including 'waste incineration power generation' as biomass energy One that incorporates renewable energy subsidy policy support and management.
Zero Waste Alliance believes that at present, according to the current document set by the MSW incineration power generation subsidy standards, in fact, all incineration plant into the plant as "biomass energy" to give policy support, not incineration of the garbage Including biomass waste fuels and non-biomass waste fuels to make a distinction, especially the included fossil fuels, represented by plastic waste.
This means that part of the electricity subsidy, which was originally intended to support renewable energy from biomass, was partly replaced by plastic waste, "said Mao.
According to the Zero Waste Alliance, according to the latest statistics, in 2015, the total volume of household garbage cleared and shipped across the country reached 291 million tons, of which 28% were incinerated (most of which could generate electricity) and the amount of incineration reached 53 million tons. If we calculate 280 tons of on-grid electricity per tonne of domestic waste, the subsidy for the whole year will be about 15 billion kilowatt-hours, and if all of the electricity is subsidized by renewable electricity tariffs (0.25 yuan per kilowatt-hour), the total amount will reach 37.5 Billion yuan. '
Mao pointed out that if we can promptly correct the problem of plastic waste incineration, we can strongly promote the source of plastic waste reduction and recycling.
