Crude glycerine for biogas
By-product of biodiesel and oleochemicals. Very rich in energy when the glycerol content is reasonable.
Feedstocks
Molasses, syrups and starch-rich liquids for biogas
Sugar and starch convert to gas quickly and completely. Liquids rich in them, from off-spec syrups to starch slurries, can be an easy and efficient addition to a feedstock mix.
Streams in this group
- Molasses and off-spec syrups
- Glucose and sugar solutions
- Starch slurries and starch-rich process water
- Rinse water and batches from sweets, drinks and bakery production
What I check
- Dry matter and sugar or starch content
- pH, since sugar-rich liquids can be acidic
- Preservatives or cleaning agents that may disturb a digester
- Viscosity and how the material can be loaded
Good to know
Because sugars are digested so fast, plants dose them steadily. A supplier with a regular stream is usually easier to match than a single large batch.
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.
Food and drink residues for biogas
Off-spec products, dairy residues, cocoa shells and other by-products from food and drink production.
