Anaerobic Digester

The 1.2 MW (megawatt) Anaerobic Digestion Plant at East Kirkby will produce green electricity and heat from Biomass Grown on farm and imported Pig Slurry.

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

The plant is located at East Kirkby disused airfield

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

The plant uses 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 is transported to the site by tanker.

Transport Movements

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


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.


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.

Useful Facts


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.
