The original concept was to construct a combined ethanol
/ biogas facility, with the intent to use the electric and thermal energies
produced by the biogas system to support the energy needs of the ethanol
production facility. Following the drop in the ethanol market, however, the
project was scaled back to electrical production from biogas only; and the
project was able to secure a contract under the available FiT program. The
project development started in 2009 and commissioning was completed in August
2012, due to delays with the utility interconnection to the grid.
What is unique about this project is that Mr.
Henrard does not own any livestock. The pig manure he receives is from the
The system also receives packaged organics from area
supermarkets. This material is initially chopped up and then mixed with
digestate to make it pumpable before it is passed on to the bioseparator
where plastics and other foreign material is removed. The material then
goes to the hydrolyzer before it enters the digester.
This process flow not only creates an increased
capacity to take in waste, but also provides for greater flexibility in
delivery schedules. Meanwhile the supermarkets enjoy the convenience of not
having to manually separate the packing from the organics they need to
The system’s effluent fertilizer is applied to his
cash crop fields.
