Why Anaerobic Digestion ?<br />
<br />
Waste Problem. (20,000 tpa green waste & rising)<br />
<br />
Not enough Cows to eat Sweetcorn By-product.<br />
<br />
<br />
Considered alternatives,<br />
◦ Landfill<br />
◦ Composting<br />
◦ Own beef lot<br />
Legislation changing, Government support increasing.<br />
(Renewable Obligation Certificates, RDPE Grants, Feed in<br />
Tariffs)

Achievements to date:-<br />
Carbon neutral electricity and heat. Self sufficient<br />
100% green waste utilisation<br />
Up to 800 acres <strong>of</strong> reduced fertiliser input<br />
Reduce carbon footprint <strong>of</strong> overall business by 97%<br />
Removed 5000 vehicle movements from local roads,<br />
previously involved in moving waste .
Future Plans<br />
Increasing capacity <strong>of</strong> existing plant to<br />
generate1.5MwH equivalent output<br />
Biogas direct to gas Grid for second phase<br />
Phosphate capture. Adding value to digestate<br />
Pelleting system to create a fuel pellet from solid<br />
digestate for burning in biomass generation plant<br />
Development work with local growers on utilising<br />
digestate as a peat alternative in propagation.
<strong>Barfoot</strong> Energy Projects <strong>Ltd</strong> formed July 2010<br />
