Introduction:
The companies
The Companies – Brocklesby Ltd
Brocklesby Ltd & Double Green Ltd
(East Yorkshire nr Hull)
• 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
Added value to Glycerine
(Collaboration with the University of York)
Greenergy Bio Fuels
• 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 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
