Biogas production

Food-waste feedstock matched to the digester, not the other way round

Biogas production from food-waste-based sources depends on what actually arrives at reception—composition, contamination, consistency and delivery rhythm. We work from the receiving plant's requirements backwards to the material.

Sourcing from food-waste-based streams

Food-waste-based feedstock can come from several kinds of source stream. What matters is not the label but the actual material: where it arises, how it is collected, how it is kept separate from other waste, and how consistent it is over time. Those practical realities decide whether a stream can serve biogas production reliably.

Quality is agreed, not assumed

Every receiving plant runs its own acceptance picture: composition ranges, contamination limits, physical form, hygiene and documentation. We match material against those requirements instead of assuming a generic "food waste" fits every digester.

Logistics shape the cooperation

Collection points, tank or container form, transport distance, delivery frequency and reception windows are part of the commercial equation, not an afterthought. A feedstock route only works when the material arrives in the right form, at the right rhythm, with the right paperwork.

Part of a wider material portfolio

Food-waste-based feedstock sits alongside our work with RDF, SRF and woodchip biomass. The principle is the same across all of them: match the material to the receiving operation, and define the cooperation before the first delivery.

Decision criteria

Feedstock is judged at reception, agreed before the first load.

Factor	Why it matters	Confirm before supply
Composition	Gas potential and process stability depend on what the material actually contains, batch after batch.	Material description, origin streams and how variation is handled.
Contamination	Packaging, plastics and other rejects create pretreatment cost and process risk.	Contamination limits, pretreatment steps and rejection criteria at reception.
Physical form	Pumping, maceration and feeding systems set what the plant can practically receive.	Form of delivery, consistency and handling equipment on both sides.
Volume and rhythm	Digesters need a steady, predictable load rather than occasional large deliveries.	Quantity, delivery pattern, seasonal variation and notice periods.
Compliance	Animal by-product rules, permits and documentation differ by material and route.	Applicable regulations, required documents and responsibilities of each party.

Define the route

Start with the receiving specification and the material that must meet it.
