1. Pearse Buckley Sustainable Energy Ireland Energy from Waste

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

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

4. What is Anaerobic Digestion?

5. Case Study – Holsworthy Biogas Plant Input 146,000 tonnes per year – Cattle, pig & poultry manure – Organic food waste Output – 2.1 MW e /14.4 GWh e – 15 GWh th to future DH system – Digestate to fertiliser

6. Case Study – Holsworthy Biogas Plant

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

8. 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 CH 4 emissions

9. SEI RD&D PROGRAMME Budget 2000 – 2006 – €16.25 million Primary goals – Stimulate deployment of renewables that are close to commercial – Assess / develop technologies which have prospects for the future

10. SEI RD&D PROGRAMME Programme categories – Projects close to commercial – 10% to 25% of eligible costs – Innovative R&D projects – up to 50% of eligible costs – Public good / commissioned public good research – 100% of eligible costs

11. SEI RD&D PROGRAMME Primary target areas – Biomass Combined Heat and Power Plants – Biomass Heating Plants – Biogas AD CHP Plants Small scale 30 kW e to 1 MW e Further information – www.sei.ie and look under “Research and Development” and “Renewables RD&D ” www.sei.ie
