1.Introduction:

The companies

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)

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

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

Biofuels from Food Waste

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

Biofuels from Food Waste - Solid fuel

Potential as solid fuel

• Microwave pyrolysis• Efficient drying

• 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)
