NatWest is helping farmers explore anaerobic digestion as one example of how a farm can increase revenue and make better use of its physical resources and characteristics.

Diversifying into green energy helped many farmers generate income when crop prices plummeted.

One of the most effective practices has been for farmers to invest in anaerobic digestion (AD) power plants. These plants take organic matter, such as food waste or maize silage, and use bacteria to turn it into a harvestable gas.

AD has been used in farming very successfully over many years for a number of purposes, including energy and fertiliser production. It’s currently the only technology in the market that meets the European criteria for second generation biofuel production, which is achieved through a range of mixed wastes – not simply purpose-grown biomass.

Installing a green energy plant in a farm is not an easy task, especially when it comes to finding the necessary funding. NatWest has supported renewable energy projects including anaerobic digestion, on and offshore wind and solar photovoltaic systems for many years.

Bob Barltrop, Sales Director at AD4Energy, a specialist in designing and building small-scale anaerobic digestion plants, commented on working with NatWest:

“Thanks to NatWest’s anaerobic digestion policy and their continual support of the renewables sector, many of our clients’ AD plants have been turned into reality. With NatWest funding our clients have been able to diversify their farms through anaerobic digestion, providing them with environmentally friendly, sustainable energy and reliable, long term income streams.”
