Slides from the Option7 Next Steps seminar at the Watermark in Ivybridge Devon UK, December 2010, SUST-N Ltd

2. Background Option7 was formed out of the community's search for a sustainable waste solution.

3. Waste Arisings in the UK Source: Defra, Waste Strategy for England 2007

4. What is Option7? Higher kerbsiterecycling rates with composting and anaerobic digestion, plus treatment of residual waste as follows: residual waste syngas MRF Biomass Gasifier biomass MRF Plasma Arc MRF non-recyclables vitrified glass metals recyclates chemicals

5. Materials Recycling Facilities glass MRF plastics metals mixed waste small textiles batteries, bulbs and tubes grit and aggregates biomass – to gasifier Benefit: Many materials that would have been burnt can be separated and recycled

6. Biomass Gasification Gasifier biomass Syngas (CO + H₂) heat Ash oxygen Syngas Combustion Combustion Chamber syngas Turbine and Generator electricity steam heat oxygen flu gases

8. Production of syngas which is flexible for future requirements, for electricity and heat, or fuel production

9. Biomass a renewable fuel – carbon neutral

10. Ability to produce our own biofuel from waste rather than displacing food production in the developing world

11. Ability to generate our own power with minimal pollution, displacing fossil fuels from abroad

14. Production of a useful inert aggregate

15. Retrieval of metals from non-recyclable products

17. Artist Impression of PREL’s Proposed Energy Park at Peterborough
