4 Barns A.D. Plant

4 Barns is a 200kW AD plant built in Romney Marsh, Kent for the Apps family. The plant is currently being fed around 10 tonnes of maize a day. Over the last month it has been operating at 95% electrical output, generating 137,000 kW/h of electricity and producing over 89,000 m³ of biogas.

 
4 Barns has and continues to be a successful project, passing its performance trial with flying colours in February 2016. The plant was fully commissioned in March 2016. It is fast becoming a local attraction, with farmers stopping by to learn more about small-scale anaerobic digestion.

 
Richard Apps, from 4 Barns farm made the following comment about the plant:

 
“There is no doubt that without the AD plant the business would not be able to sustain current levels of employment with the low commodity prices.

 
Economically, the plant is extremely beneficial to the business’ financial health… Fundamentally we can budget on our return and avoid some of the risk from the heavily volatile markets, which the agricultural industry faces today.

 
As our plant runs on 100% energy crop, it has given us extra crops to our rotation. This is one of the few weapons we have to fight against an ever increasing blackgrass problem… The larger variety of crops in our rotation has allowed us to decrease the blackgrass seed bank in the soil and still gain a good margin per hectare.

 
Due to the size of our plant we are really excited about spreading the nutrient-rich digestate onto our land… It will help to dramatically boost organic matter in the soil as well as considerably reducing our compound fertiliser bill.”
