WHY ENERGY FROM WASTE? Industry Perspective SEI Perspective A waste management solution A waste recovery process A cost saving SEI Perspective Renewable energy Security of supply Greenhouse gas abatement

TYPES OF ENERGY FROM WASTE Mass burn Novel technologies Gasification, pyrolysis, etc. Anaerobic Digestion Organic fraction of waste stream Landfills

What is Anaerobic Digestion?

Case Study – Holsworthy Biogas Plant Input 146,000 tonnes per year Cattle, pig & poultry manure Organic food waste Output 2.1 MWe/14.4 GWhe 15 GWhth to future DH system Digestate to fertiliser

Case Study – Holsworthy Biogas Plant

TYPICAL COSTS Capital cost €3,500/kW O & M €350/kW

BENEFITS Waste management through Added Value Community involvement dimension Renewable Energy Secure energy supply GHG savings Holsworthy 10,500 tonnes/yr – power generation 4,000 tonnes/yr – district heating Avoided CH4 emissions
