3. 1. Introduction: The companies

4. The Companies – Brocklesby Ltd Formed in 1987 and moved to current 10 acre site in 1997 A leading processor of used edible oils and fats primarily from the UK retailers and c150 food manufacturers Innovative manufacturing techniques processing in excess of 80KT PA A processor of food waste (new activity over last 12 months) generating bio fuel feedstock and starch co product Manufacturing a range of products for the UK & EU bio fuel markets Operating from a ten acre site, 24/7 with 55 employees Dedicated fleet of vehicles In final stages of £3m spend on acid esterification plant to process 50KT PA Brocklesby Ltd & Double Green Ltd (East Yorkshire nr Hull)

5. Added value to Glycerine (Collaboration with the University of York)

6. Immingham Own and operate a bio diesel production facility in the port of Immingham on the east coast of England Current 200kt/year name plate capacity on veg oil, £44m capital investment to build Has sea, rail and road access as well as pipeline links to local petroleum oil refineries Sea-fed location enables effective logistics and trading with the UK and European biodiesel markets as well as the wider world feedstock markets Plant runs on waste oils such as Used Cooking Oil (UCO) and Tallow. Plant is operated by PX Limited on behalf of Greenergy North Cave Greenergy Bio Fuels

7. 2. Biodiesel feedstocks and the conversion process

8. Typical Biodiesel Feedstocks Refined Vegetable Oil FFA<0.5% Traces of moistures & impurities Initial specification for the plant Fats, Used Cooking Oils & recovered olis from food waste Typically 5 – 15% ffa & 2% M&I Pre-treatment required

9. The commercial process Feedstock (Tallow, UCO, Vegetable oil) Distillation, chemical reaction and purification Biodiesel (FAME) Methanol Glycerol Oleines FFA RAW MATERIALSSTEAM ETC. PRODUCTS += Waste Water > 90% YIELD

10. 3. Bio fuels from Food Waste (North Cave Project)

11. FOOD PRODUCER -Anaerobic Digestion -Fermentation -Added value products (Food waste) BIOFUEL MARKET UK and Europe Compostation (Farm facility) Food Processing Land spread Food Co-product Oil (20 - 30% yield) High Temperature 130 o C CURRENT EXPECTED Biofuels from Food Waste

12. Biofuels from Food Waste requires Acid Esterification The Immingham biodiesel plant’s refineries can only process relatively low free fatty acid (FFA) materials and therefore bottlenecks occur when high FFA feedstock is sourced Off site acid-esterification to convert FFA to esters, allows the plants refineries to be bypassed which increases the overall production capacity of the plant and importantly from food waste Continuing uncertainties with government legislation supports an off site pre esterification plant as it provides flexibility when sourcing feedstock The North Cave JV project is in line with Greenergy’s broader business plans of becoming the worlds biggest user of waste based bio fuels as it allows greater in house production of low cost bio fuels

13. Biofuels from Food Waste - Solid fuel Potential as solid fuel Microwave pyrolysis Efficient drying

14. Liquid effluent to Biogas Processing of various effluent streams Promising results in collaboration with the University of York Plant for commissioning 2013 (currently evaluating best technology providers) Biofuels from Food Waste - Biogas
