AD ‘Can Help With UK Soil Management’
Anaerobic digestion (AD) can be used for more than just producing energy, with the Anaerobic Digestion and Bioresources Association (ADBA) recently stressing that the sector can play an important role in the management of the UK’s soil.
The Department for Energy, Food and Rural Affairs (Defra) recently launched a 25-year environmental plan, part of which covered sustainable soil management and the aim to develop “good nutrient management practices” for the country’s soil.
Renewable Energy Magazine reported on the plans, with ADBA chief executive Charlotte Morton explaining “the AD industry can play a key role in this through producing natural, low-emission biofertiliser in the form of digestate, which is high in vital nutrients such as nitrogen, phosphorous and potassium”.
However, the publication noted that not all areas of England offer residents separate food waste collections, and that this is one key thing that needs to change going forward.
In both Scotland and Wales, it is already mandatory for local authorities to provide a separate food waste collection for residents.
As well as supporting AD plants around the nation to deliver heat and power, biofertiliser and low-emission fuel, introducing more food waste collections has also been shown to encourage people to waste less food in the first place.
The ADBA recently launched a certification scheme for those running AD plants, which is designed to improve safety and performance by putting a focus on the quality of digestate and energy output.
