AcrEnergy focuses on those feedstock streams where there is enough land for digestate off-take. It means farmers play a very important role in contributing towards green gas production.

We only turn waste and break crops to green gas if enough farmland is available surrounding the plant to spread the residue from those plants.

The feedstock we work with is derived from a number of sources including food production, residential waste collection and / or the farms.

The residue from the plant is an organic and liquid nutrient-rich fertiliser which feeds the crops and grassland, but it is also a soil conditioner.

AcrEnergy secures the farmer not only a long-term fixed income stream but allows his business to be more, if not entirely, sustainable.

AcrEnergy’s business model is structured so that it serves as an additional income stream for those businesses that produce the waste as feedstock to its plants.

Those food producers, farmers and / or municipalities can secure a long-term off-take agreement with us for their waste.

In case of the farmer we would be looking for part or all of her / his rotational crops (i.e. break crops) as well as “store” her / his livestock waste (chicken, beef, dairy, pigs even horse manure) and / or vegetable waste in the plant instead storing in a heap on the farm.

We welcome all of our feedstock providers to co-invest in the plant, but it is not required.  All costs from development through to construction and operations can be borne by AcrEnergy and its investors.

Sustainability

The residue from the biogas plant is a nutrient-rich digestate, which can be used as fertilizer and soil conditioner on the fields.

Nutrients (e.g. nitrates, phosphates and potassium) that are extracted from the organic feedstock are returned to the soil through the application of the digestate. Hence the need to procure and apply artificial, fossil fuel-derived fertilizers is substantially reduced – if not entirely eliminated.

An even more valuable effect of applying the digestate is its soil conditioning properties. It proves itself in the long term. Please refer to the British Society of Soil Science for more information www.soils.org.uk

The digestate is also odour free and environmentally safe compared with alternative organic fertiliser such as farmyard manures or compost. The AD system removes pathogens and odours from any waste – including residential food waste, abattoir waste and farm-yard manures.

The digestate from the biogas plant is readily available for crop uptake making the digestate a more predictable fertiliser than fossil fuel based fertilizer.

Avoid landfill and any other forms of waste storage costs

We are the solution for increasing levels of obligations for municipalities and food manufacturers to segregate their food waste and divert it from landfills: we can process all of it in a biogas plant!

Livestock farmers will be able to avoid the capital expenditure for a new storage tank to control methane emissions from the “muck” (up to 20x more potent than CO2). Instead, the biogas plant will take this waste to “store” it, produce energy and fully recycle it to an organic fertilizer to spread to land (arable and grazing land).

 

Remove Black Grass weed

Break crops such as corn stover, sugar beet or rye grass contains if not eliminates black grass weed. Long term research and development has proven for those break crops to be invaluable in the rotation with the main crop such as cereal or vegetables. While KWS promotes maize as an ideal control wrap back in January 2013 they already established break crops for biogas feedstock has great benefits in tackling weed problems for farmers.
