NP117  Decentralised Power Generation with Syngas, Biogas & Landfill Gas Waste Management
This research will determine whether gas from small-scale digestion and gasification of carbonaceous and putrescible waste can be combined with landfill gas to increase, or make viable, power generation from landfill sites. The project will evaluate digestion and gasification technologies and how they might provide an increase in the contribution to renewable energy targets.

The work includes:

  • A feasibility study to investigate practicalities of combining landfill gas with gas digestion and gasification of waste biomass
  • Preparation of a technical specification for a demonstration project.

The research will:

  • Investigate practicalities of combining landfill and other gases
  • Determine size and security of fuel supply and identify competing uses
  • Identify availability of commercial/new digestion or gasification equipment
  • Assess implications of mixed gases on operation of power generation units
  • Assess economic viability of the proposal
  • Evaluate environmental cost/benefits compared to alternative methods managing organic wastes in compliance with Landfill Regulation
  • Produce a costed plan for a project plant.

The research is a collaboration of the UK Department of Trade & Industry (DTI), Advantica, Thames Water, Texas Utilities (TXU), 2 Landfill Operators, 4 Environmental Bodies with WRc who are undertaking the work.

Benefits

  • Identification and evaluation of alternative digestion and gasification technologies
  • Compliance with Landfill Regulations by reducing organic waste to landfill
  • Increase contribution that landfill gas makes to achieving renewable energy targets
  • With additional on-site waste derived gas sources, extend period of commercial landfill gas utilisation; or make economically viable using landfill gas at sites where production from landfill gas alone would not be commercial
  • Provide income to site operators through electricity generation
  • Promote improved gas management reducing environmental impact
  • Maximise recovery and use of chemical energy available in waste.
