Crude glycerine for biogas
By-product of biodiesel and oleochemicals. Very rich in energy when the glycerol content is reasonable.
Feedstocks
Food and drink residues for biogas
Food factories produce batches that cannot be sold: wrong recipe, damaged packaging, past the date. Many of them are rich in fat, sugar or starch and well suited to a digester.
Streams in this group
- Off-spec or expired food and drink
- Dairy residues such as permeate and off-spec dairy products
- Cocoa shells and other solid residues from food processing
- Bakery and confectionery residues
What I check
- Dry matter, fat and organic matter
- Packaging: whether it needs to be removed first
- Whether any animal-derived material is involved
- Legal status and EWC code
- Regular stream or one-off batch
Good to know
Solid streams are possible, but the receiving plant needs the right intake. I check that before making an introduction.
Other feedstocks I work with
Oils, fats and soapstock for biogas
Soapstock, acid oils, off-spec vegetable oil and fatty residues. Fat carries more gas per tonne than almost anything else.
Vinasse and fermentation residues for biogas
Vinasse and other residues from yeast, ethanol and sugar fermentation. Concentrated batches are the interesting ones.
Molasses, syrups and starch-rich liquids for biogas
Molasses, off-spec syrups, sugar solutions and starch slurries from food and starch processing.

Phone and WhatsApp work best for a first conversation. I speak Dutch and English. Writing in your own language is fine.
