- On-farm AD plants convert wastes and crops into renewable energy and biofertiliser
- Value of operational expenditure on on-farm AD expected to exceed £150m p.a. by 2020
- Potential for ten-fold increase in number of on-farm AD plants across UK
There are “multi-million-pound financial opportunities” from on-farm anaerobic digestion (AD) plants across the UK, according to the trade body for the AD industry and a leading renewable energy project funder.
On-farm AD plants allow farmers to convert agricultural wastes (such as manures and slurries) and purpose-grown crops (often grown as part of a traditional rotation) into renewable heat and power and nutrient-rich biofertiliser. There are currently 334 AD plants using agricultural feedstocks across the UK, up from just 66 in 2013.
Charlotte Morton, Chief Executive of the Anaerobic Digestion & Bioresources Association (ADBA), said:
There are multi-million-pound opportunities in refinancing and upgrading the over 300 on-farm AD plants now operating across the UK to make these plants more efficient and deliver greater financial and environmental value. We estimate that the value of operational expenditure on all UK on-farm AD plants will be £150 million per annum by 2020.
With a further 300 on-farm AD plants having received planning permission and the potential for the current number of on-farm AD plants to increase ten-fold, these financial and environmental opportunities are only going to increase over the coming years.
Phil Gerrard, Chief Executive of renewable energy funders Privilege Finance, agreed that the opportunities for on-farm AD are widespread:
Having invested over £300m in agricultural and food waste renewable energy projects, we know from experience that AD is a viable way of creating energy from what would typically be considered waste products.
Agricultural plants have been the primary driver of AD growth over the past five years, and the agricultural sector is now the largest in the AD industry, outstripping wastewater and food waste both by number of plants and energy capacity. Of the 54 new AD plants commissioned in 2017, over three quarters were agricultural plants.
ADBA estimates that there are at least 4,300 dairy farms across the UK with dairy herds of 150 cows or more for which AD would be viable. Only two of the 90 million tonnes of farm wastes produced in the UK are currently recycled through AD, but recycling all farm wastes would fulfil around 90% of the Committee on Climate Change’s 2030 decarbonisation target for agriculture by reducing emissions from agricultural wastes.
“With opportunities to reduce agricultural emissions, decarbonise the grid and generate more green gas for the UK network, it’s undeniable that on-farm AD can help the government to achieve its Carbon Budgets,” Mr Gerrard added.
ADBA recently called on the government to provide clear and meaningful incentives for farmers to introduce AD into their farming operations and use digestate-derived biofertiliser as part of its proposed Agriculture Bill.
