Grass clippings, leaves, hedge trimmings and woody prunings differ substantially in composition and accessibility. Commercial landscaping waste and separately collected household green waste should be sampled representatively before selecting enzymes. Collection method, storage and seasonal changes also matter.
Food processing and mixed residual materials
Suitable segregated food manufacturing by-products, fibre-rich process residues and emerging biomass may contain recoverable starch, cellulose or hemicellulose. Novel feedstocks are an application category, not a third generation of bioethanol. Whether a stream fits a starch-based or cellulosic route depends on its composition.
An analysis-led enzyme selection service
Screen
Compare amylase, cellulase, hemicellulase or complementary blends against appropriate controls under agreed conditions.
Evaluate
Assess sugar release and fermentation compatibility, then calculate enzyme cost on a consistent feedstock basis.
From waste material to a practical trial
Mixed waste can contain plastics, grit, metals or inhibitory substances. Enzymes do not remove these contaminants. Discuss sorting, pretreatment and sample handling before sending material. Suitability for ethanol production needs to be established experimentally; we do not assume every organic waste stream is fermentable.

Enzyme options by feedstock.
| Feedstock | S&T enzymes to discuss | Trial focus |
|---|---|---|
| Commercial / household green waste | Plant Max Yield Pro ↗ · Cellulase ↗ · β-Glucosidase ↗ · Xylanase ↗ · Feruloyl esterase (FAE) ↗ | Accessible cellulose and hemicellulose; seasonal composition and lignified fractions. |
| Starch-rich food residues | High-temperature α-amylase ↗ · Glucoamylase ↗ · Pullulanase ↗ | Starch conversion; assess protein and fibre activities only where composition supports them. |
| Mixed / emerging biomass | Cellulose Max Yield Pro ↗ · Xylanase ↗ · Feruloyl esterase (FAE) ↗ · Laccase ↗ | Screen carbohydrate release and any separate phenolic treatment; no fixed blend assumed. |
These are candidate activities for screening, not a fixed recipe. Bespoke cellulase and accessory-enzyme blends can be tailored to the material. Bulk blend supply options are quoted separately from the retail catalogue formats.
FAE and laccase: different roles.
Feruloyl esterase targets ferulate ester linkages and can complement xylanase on suitable plant materials. Laccase acts on phenolic substrates and requires oxygen; assess it as a separate treatment where useful. It is not a universal lignin-removal enzyme, and its effect on fermentation inhibitors must be measured.
