Digestate Dryer Manufacturer in the United Kingdom
See how we dry Digestate FibreLooking for digestate dryers manufacturers in the United Kingdom? STRONGA builds FlowDrya lines to order at its Hertfordshire works and supplies them to the United Kingdom — see the regulatory and economic context below.
For digestate we can point to a documented British project. Our JB Vaughan installation in England dries separated digestate fibre on a FlowDrya line built to order at STRONGA's Hertfordshire works, and it is one of three UK reference sites listed above. Drying matters here because a digestate that meets the BSI PAS 110 specification and the Anaerobic Digestate Quality Protocol can cease to be waste and be sold as a quality biofertiliser; stabilising the fibre to a low, even moisture protects those nutrients and that end-of-waste status. Because separated fibre is corrosive, British digestate machines are supplied with a stainless-steel package.

Regulatory context
Operating a plant that stores, treats or dries a waste-derived or organic material normally requires an environmental permit from the Environment Agency (or the devolved regulator in Scotland, Wales and Northern Ireland); the operator must demonstrate technical competence and comply with the permit conditions.

Digestate from anaerobic digestion of source-segregated biodegradable waste that meets the BSI PAS 110 specification and the Anaerobic Digestate Quality Protocol can cease to be classified as waste and be marketed as a quality biofertiliser.

Applicable standards: EN ISO 21640, EN ISO 17225-4, PAS 110, PAS 100.
Economic context
Landfill Tax on the disposal of most active waste in England and Northern Ireland is £130.75 per tonne from 1 April 2026 (the lower rate for inert waste is £8.65 per tonne); Scotland and Wales apply aligned devolved rates. The escalating tax is the primary economic driver for diverting material away from landfill.

The median UK gate fee for non-hazardous landfill, excluding Landfill Tax, was £34 per tonne in WRAP's UK Gate Fees Report 2025-26, and median energy-from-waste gate fees rose again across all categories surveyed.

UK manufacturers paid an average of 17.08 pence per kWh for electricity and 3.71 pence per kWh for gas in Quarter 2 2025 (DESNZ Quarterly Energy Prices, September 2025). High industrial electricity prices reward drying equipment that runs on recovered waste heat and minimal electrical power rather than direct electric heating.

Biomethane produced by anaerobic digestion and injected into the gas grid can receive 15 years of tariff support under the Green Gas Support Scheme, administered by Ofgem and open to new applications until 31 March 2028, improving the economics of AD sites that must also manage and dry their digestate.

Worked illustration (assumptions stated):
An anaerobic-digestion operator earns from more than the digestate. Biomethane injected to the grid can draw 15 years of Green Gas Support Scheme tariff support, open to new entrants until 31 March 2028, so the site is often already heat- and cash-generative before the fibre is dried. Drying then converts a storage-and-spreading liability into saleable PAS 110 biofertiliser, animal bedding or a solid fuel, avoiding the cost of tankering wet material and the Landfill Tax of £130.75 per tonne that any rejected fibre would attract. With British gas at 3.71 pence per kWh, running the dryer on the plant's own combined-heat surplus keeps the operating cost low. Assumptions: incentive eligibility and offtake prices are site-specific.

Digestate Dryer Manufacturer in the United Kingdom — FAQ
Do you have a UK digestate drying installation?
Yes. Our JB Vaughan project in England is a working FlowDrya digestate fibre line, and it appears in the UK installations listed on this page alongside our bark and woodchip references.
How does drying protect digestate's biofertiliser status?
End-of-waste under PAS 110 and the Quality Protocol depends on a consistent, specified output. Drying the fibre to a stable low moisture concentrates the nitrogen and phosphate, prevents leaching in storage and keeps the product within the specification a buyer relies on.
Which regulations govern digestate here?
A permit from the Environment Agency usually applies to the digestion and drying operation, while PAS 110 and the Anaerobic Digestate Quality Protocol set the criteria under which the dried fibre may be traded as a biofertiliser rather than handled as waste.
What end markets take dried digestate fibre?
Depending on the grade, buyers include arable growers seeking a phosphate-rich soil improver, equestrian and livestock yards wanting absorbent bedding, and pellet mills producing a compact renewable fuel. A drier, friable fibre travels economically and blends predictably.
Does the FlowDrya suit corrosive digestate long term?
Yes. The stainless-steel enclosure resists the acidic, ammonia-laden vapour that shortens the working life of mild-steel dryers, giving anaerobic-digestion operators a durable asset with decades of expected service.
