Source-Separated Food Scraps
Preparation scraps and unavoidable food residues can vary in liquid, salt, fat, packaging and collection age.
- Separate edible surplus before treatment
- Record liners, cutlery and packaging contamination
Material Application Guide
Organic Waste Recovery
Keep preventable food, source-separated organics, green material and contaminated residuals on distinct routes. Biological treatment depends on feedstock quality; conventional baling does not treat wet or biologically active organic waste.

Protect the Organic Stream
Define prevention and treatment before mechanical handling.
Start by identifying edible surplus or avoidable loss that should not become treatment feed. For unavoidable material, record the source, composition, packaging, free liquid, contamination and collection time instead of relying on a general organic-waste label.
Composting and anaerobic digestion are different biological processes with their own acceptance and process controls. Collection and pre-processing should meet the selected facility’s input rules; shredding, dewatering or compression alone does not produce stable compost or digestate.
Return to the Material AtlasOrganic Streams
Keep feedstocks separate where treatment behaviour differs.
The receiving treatment specification should define which organic materials can be combined and which require another route.
Garden and Green Material
Leaves, grass, branches and woody bulking material differ in particle structure, moisture and biological breakdown.
- Separate soil, stones and treated wood
- Define cutting and blending duty
Packaged or Contaminated Organics
Expired packaged goods and mixed loads need a controlled depackaging, rejection and traceability basis before treatment.
- Identify packaging materials and contents
- Quarantine chemicals and unsuitable waste
Recovery Sequence
Prevent, separate and clean the feedstock before treatment.
Mechanical preparation supports a defined biological route; it does not replace treatment acceptance, process control or output verification.
- 01
Prevent and Redirect
Separate edible surplus and avoidable losses according to the site’s food-management and legal procedures.
- 02
Collect at Source
Keep accepted organics apart from dry recyclables, hazardous products and general residual waste.
- 03
Remove Packaging and Contaminants
Use a controlled inspection and depackaging basis that accounts for films, metals, glass, cutlery and rejected contents.
- 04
Match the Treatment Recipe
Confirm feedstock mix, particle preparation, moisture, collection time and delivery rules with the composting or digestion facility.
Equipment Review
Review equipment as part of the accepted biological route.
Organic feedstock does not select a machine by itself. The treatment operator’s acceptance rules, contamination controls, mass balance and hygiene plan define the required interfaces.
Source Separation and Treatment Feed
A coordinated system may be reviewed for receiving, inspection, depackaging, transfer and preparation of an accepted organic feedstock.
- Treatment facility acceptance documented
- Reject and packaging routes defined
- Liquid and hygiene controls established
Separated Packaging Densification
Baling may be reviewed only for an emptied, separated and sufficiently dry packaging fraction with a confirmed receiver.
- Organic contents removed to the accepted limit
- Hazardous and pressurised items excluded
- Packaging grade and bale route defined
Wet, mixed or biologically active organic material is not established as conventional baler feed by this guide. Equipment suitability and treatment performance require project-specific confirmation.
Treatment and Outputs
Track organics, rejects and recovered packaging as separate outputs.
The organic feed, removed packaging, physical contaminants, process losses and biological outputs require their own mass-balance and destination records. A reduction in volume is not evidence that biological treatment or product quality has been achieved.
Compost is produced through managed aerobic decomposition, while anaerobic digestion produces biogas and digestate under different conditions. Confirm the applicable facility controls and output requirements rather than transferring assumptions between routes.
Site Interfaces
Control time, liquid, hygiene and contamination from collection to treatment.
A practical layout should prevent cross-contamination and support cleaning, drainage, inspection and contained transfer.
Reception and Inspection
Provide load identification, contamination checks, sampling access and a controlled reject or quarantine area.
Drainage and Washdown
Contain free liquid and cleaning water under the site’s drainage, wastewater and hygiene arrangements.
Storage and Collection Time
Define enclosed or covered storage, stock rotation and collection frequency for the accepted feedstock condition.
Treatment and Reject Transfer
Coordinate pumps, conveyors, containers and vehicles with spill control and separate destinations for organics and rejects.
Safety Boundary
Treat biological activity, liquids, gas and contaminants as process hazards.
The installed system requires feedstock-specific risk assessment, hygiene controls, safeguarding and emergency procedures.
- Reject chemicals, batteries, glass and sharp contaminants
- Control access to depackaging, cutting and transfer zones
- Isolate energy before clearing blockages or wrapped material
- Manage bioaerosol, odour, liquid and pest exposure
- Assess gas, confined-space and fire risks for the chosen treatment

Application Questions
Organic Waste Recovery FAQs
Can wet organic waste be compacted or baled for recovery?
Compaction does not provide biological treatment and may create liquid, hygiene, corrosion and storage issues. Define prevention, source separation and an accepted composting, digestion or other authorised route first.
Are composting and anaerobic digestion the same process?
No. Composting is managed aerobic decomposition; anaerobic digestion operates without oxygen and produces biogas and digestate. Their feed, process and output rules must be reviewed separately.
How should packaged food waste be prepared?
Record the product and packaging, then confirm depackaging, contamination, liquid and reject limits with the receiving treatment facility. Do not assume every package or content is acceptable.
What should an organic-recovery enquiry include?
Provide source and composition, preventable and unavoidable split, packaging, contaminants, moisture, free liquid, normal and peak arrivals, collection time, treatment destination, reject route, utilities and layout.
