Biomass Plant

The one mile wide Anaerobic Digestion Plant at East Kirkby will produce green electricity and heat from Biomass Grown on farm and imported Pig Slurry.

The plant will meet the Governments requirements for Combined Heat, Power & Anaerobic Digestion Biomass plants.

Electricity produced will be exported to the local electricity network via an underground cable.

The Plant will also produce Renewable Heat which can be used for heating in Commercial Buildings or for growing greenhouse crops.

The plant will be located at East Kirkby disused airfield.

The plant produces circa 1000 Kilowatts per hour of electricity and a similar amount of heat, some of which will be utilised in the process and the remainder could be used for heating in greenhouses and the local business park.

The plant will be a tried and tested design and is a replica of many plants operating successfully in Germany, Austria and Holland.

The plant is very quiet whilst Operating and produces no discernable smells!

Sources of Feedstock

The Plant will process vegetable trimmings together with whole crop maize locally grown supplemented by pig Slurry which will be transported to the site by tanker.

Transport Movements

There will be a slight increase in transport movements to the site during harvest and there will be one load of vegetable trimmings and one to two tanker loads of pig slurry per day.

Odour

The transfer process for the pig slurry is totally enclosed which will reduce odours to zero and the anaerobic process produces no smell as the methane is fed to the biogas engine directly in sealed pipes.

Noise

The plant is very quiet and the gas engine is located in an acoustic enclosure which reduces noise to within statutory limits.

Plant Operation

The waste feedstock will be fed directly into a mixing vessel together and then fed into sealed Digesters via a screw conveyor where an anaerobic reaction takes place forming methane and other gases together with a residue which is an excellent fertiliser.

The gas is then fed into a reciprocating gas engine which is connected to a generator which produces electricity.

Liquid and solids will be separated via a press and the residual solid and liquid residues will be spread as fertiliser on local farmland.

The residue has no smell and can be stored easily in both solid and liquid form for use as a fertiliser / soil modifier.

Useful Facts

Electricity

The plant will provide electricity for 2150 households which is enough to power a town the size of Spilsby.

CO2 Savings

Agriculture is one of the main contributors to CO2, this is why the A.E. Lenton Group want to introduce this process to reduce their overall carbon footprint. The production of electricity and heat in the plant will save approximately 3000 tonnes of CO2.
