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
Overview- Justification for research- Review of energy from waste (EfW) and renewables development in UK- Research Findings- Recommendations and Conclusion
The Case for Renewables and EfW- Energy Supply Security- Climate Change Mitigation- Sustainability/ Resource Efficiency
EfW Technologies Notes: EfW= energy from waste; LFG= landfill gas; AD= anaerobic digestion; H2= Hydrogen
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
Global car fleet projected to rise from 650 million in 2005 to 1.4 billion units in 2030 (IEA, 2008).
If present policies continue, fossil fuels to account for about 80% of global energy supply by 2030 (IEA, 2008).
UK transport sector accounts for 70% of oil demand (BERR, 2008); and a quarter of all UK CO2 emissions (DECC, 2009).

EfW and waste management characterised by changes in legislation, technologies and market consolidation.
Changes in waste composition, together with waste prevention and increasing recycling efficiency may render some EfW facilities redundant (Adamson, 2008).
Potential for ‘over capacity’ with technologies like AD and thermal EfW resulting in feedstock shortage.
Greater support from Government for increased use of EfW and renewables.
Better engagement of UK public through effective communication of benefits.
Greater collaboration among Government, academia and industry to ensure research feeds into deployment of technologies and vice versa.
Renewables and low-carbon technologies should be given higher priority for investment.
EfW and renewable technologies are very important for the UK’s energy security and climate change mitigation.
EfW could contribute up to half of the renewables target by 2020.
Greater support for investors needed to ensure more speedy deployment of renewable energy technologies.
