3 Global Challenge 2 - Sustainable Energy Base load vs. Low Cost vs. APP Low Carbon vs. 3

4 Introduction to APP Established in 2005 to develop and commercialise the globally patented Gasplasma EfW technology Pilot plant operated from 2005 Swindon plant operating since 2008 Objective - leader in the waste to renewable energy/fuels market delivering responsible resource management Substantial project pipeline includes waste/engineering companies from UK, Western Europe, USA, Canada, Brazil, Korea, Middle East, Poland 4

5 Tetronics Background World leader in DC Plasma Arc Technology, supplying globally Established 1964 in Faringdon, Oxfordshire 80 installations globally Systems operating for decades with high availability in the most demanding environments Plasma technology a key component in the APP Gasplasma process 5 5

6 Areas of Application Waste to energy - Gasplasma Vitrification of incinerator waste and Air Pollution Control (APC) residues Nuclear waste (low and intermediate level) Other industrial applications include: Spent pot liner (SPL) from Aluminium industry Persistent organic pollutants (POPs e.g. PCBs, Dioxins, Pesticides etc.) Base metal recovery (e.g. electric arc furnace dust) Precious metals and Platinum Group metals recovery 6 6

7 Equipment Proven Worldwide North America Tetronics = 8 Plants EPI = 77 Plants Europe Tetronics = 22 Plants EPI = 8 Plants Asia Tetronics = 52 Plants EPI = 8 Plants Latin America Tetronics = 1 Plants EPI = 1 Plants Australia EPI = 1 Plants 7

8 Conventional EfW Inefficient steam cycle No recyclate removal High volume of residual ash (cost and regulatory risk) On site combustion only Concerns over emissions Significant visual impact Little government support Deeply unpopular 8

9 How is Gasplasma different? For many years, developers have been trying to convert waste into a gas that can be used in a gas engine for electricity and heat generation. APP has overcome the major obstacle to the use of waste gasification to power such gas engines. Implications: Greater energy efficiency Greater support (ACT = 2 ROCs in UK) Smaller scale Products offering greater versatility Fichtner Consulting Engineers 9
