Renewable Energy, Landfill Gas and EfW: Now, Next and Future

1. The Chartered Institution of Wastes Management (CIWM) Geotech Award 2009“Renewable Energy, Landfill Gas and EfW- Now, Next and Future”.KOFI A. ADU-GYAMFICIWM Annual Awards CeremonyOne Great George Street, London20th October, 2009

2. Overview- Justification for research- Review of energy from waste (EfW) and renewables development in UK- Research Findings- Recommendations and Conclusion

3. The Case for Renewables and EfW- Energy Supply Security- Climate Change Mitigation- Sustainability/ Resource Efficiency

4. EfW Technologies Notes: EfW= energy from waste; LFG= landfill gas; AD= anaerobic digestion; H2= Hydrogen

5. UK Government Support for EfW and Renewables Climate Change Levy Exemption Low Carbon Buildings Programme Grants Feed-in tariffs (FITs) (from 2010) Renewables Obligation Certificates (ROCs) EfW Renewables Renewable Heat Incentives (from 2011) Bio- Energy Capital Grants Landfill Tax Escalator + Landfill Allowance Trading Scheme Renewable Transport Fuels Obligation (RTFO) Credits

7. Calorific values for undiluted LFG between 15 and 21 MJ/m3, compared with about 37 MJ/m3 for natural gas (Williams, 2005).

9. Heat

10. Biomethane for grid injection/ transport fuel

13. If present policies continue, fossil fuels to account for about 80% of global energy supply by 2030 (IEA, 2008).

16. Economy: 55% more economical than petrol and 40% cheaper than diesel (STSL, 2006).

17. Potentially safer than petrol.

18. Gas vehicles less noisy than conventional ones.

19. Feedstock available in EU and supplies may be augmented with natural gas.

21. Public take ownership of their waste management.

22. Community involvement reduces planning bottlenecks.

23. Reduced carbon footprint due to minimal waste transportation.

26. Changes in waste composition, together with waste prevention and increasing recycling efficiency may render some EfW facilities redundant (Adamson, 2008).

28. Better engagement of UK public through effective communication of benefits.

29. Greater collaboration among Government, academia and industry to ensure research feeds into deployment of technologies and vice versa.

31. EfW could contribute up to half of the renewables target by 2020.

33. Each to their own?
