Anaerobic digestion involves harnessing the natural process whereby organic matter is broken down by bacteria in the absence of oxygen to produce biogas. This can be used as a renewable energy source, both for heat and power. Alternatively, the carbon dioxide and other impurities can be removed to produce biomethane which can be used as a transport fuel or injected into the gas grid. The treated material (digestate) can be used as a fertiliser and soil conditioner.
Anaerobic digestion has significant potential to contribute to the UK’s climate change and wider environmental objectives. The diversion of biodegradable wastes to anaerobic digestion can reduce greenhouse gas emissions from landfill. Similarly, it offers the opportunity to capture methane from manures and slurries and so reduce emissions to the atmosphere. By producing renewable energy, anaerobic digestion offers the opportunity for farmers to cut their energy bills and reduce their environmental footprint. The sale of surplus energy and digestate offers a potential additional revenue stream and valuable diversification for rural businesses.
Anaerobic digestion on farms can generate renewable energy in the form of biogas using manures, slurries, crop resuidues or biocrops as a feedstock. The biogas can be used to generate heat and electricity for use on farm or sold to third parties. Where appropriate, these plants can be integrated into manure and slurry management systems and so contribute to the mitigation of greenhouse gas emissions and improved nutrient management.
Digestate will be recognised throughout the food supply chain as a valuable fertiliser and soil conditioner.
The NFU vision for anaerobic digestion sets an aspiration of 1000 farm based anaerobic digestion plants by 2020, alongside at least 100 larger waste-linked anaerobic digestion facilities in which farmers may also have an interest
Anaerobic digestion of animal slurry, vegetable waste, silage and specifically grown crops (e.g. Maize) is a process that requires professionally designed and manufactured equipment to collect, store, pressurise, burn, clean and use biogas to generate electricity, provide heat, run hot water boilers and eventually to fuel vehicles and inject back into the natural gas grid network.
We have the process and engineering knowledge to build and construct farm digesters here in the UK. We are flexible in our designs and approach to construction and will work with you to build cost effective Anaerobic Digesters.
Constructing tanks to our design and purchasing major items of plant yourself will help avoid mark-ups and reduce considerably the build cost.
We design simple and robust anaerobic digesters using rectangular concrete tanks or lagoons. Delivered containerised and pre-built mechanical and electrical plant minimise installation times.
