Biomass Wastes-to-Energy in China - Biogas from Landfills or Anaerobic Digestion Plants?

The National Development and Reform Commission (NDRC) in China has acknowledged that till 2050 up to one third of three billion tons of coal per year could be replaced by biomass energy in China. Renewable Energy from biomass waste is one of the pillars in China’s long term power supply strategy, targeting 15% renewable energy generation or about 600 GW in 2020. Landfill gas, including biogas from waste water treatment plants and from agriculture biogas plants are seen as the main sources (NDRC 2007).

Based on the fact that landfilling is the most widely used type of waste disposal in China, accounting for 80% of the 'collectedâ€� municipal solid waste (MSW), the expectations to develop engineered landfilling, including landfill gas utilization as a valuable waste treatment option, failed, although these efforts have been supported financially through carbon credits from the industrialized countries and the Clean Development Mechanism (CDM) of UNFCCC. The low amount of certified emission reduction (CER) through landfill gas methane flaring or utilization reached is already an indication that Chinese landfills are behaving differently than landfills in developed countries (UNFCCC 2009). The better option, to make use of the high bio-gas potential of the waste, would be to set up biogas plants, where the biogas derived from the rapidly decaying organic matter in the MSW is generated under controlled conditions. As the agricultural sector is currently setting up thousands of medium and large scale biogas plants (MLBGPs) to treat  manure and agro processing waste, co-processing of bioorganic municipal waste (BMW) shall be considered instead. The first pilot projects are on the way (e.g. Harbin 2010). Biogas from wet biomass waste should become priority in the Chinese waste management and renewable energy policy in order to reduce the greenhouse gas emissions and replacing gradually fossil fuels.
