Zero Waste to Landfill Certification: How Factories Get There
Environmental · 2026-07-28 · 1 min read · CR Global Assurance Editorial Team
Fabric offcuts, cartons, sludge and plastic all have a destination. Zero Waste to Landfill certification proves that destination is reuse, recycling or recovery — not a dump site.
Waste is one of the most visible sustainability indicators for factories. Zero Waste to Landfill (ZWL) certification from CR Global Assurance independently verifies that a facility diverts its waste from landfill and open dumping through reduction, reuse, recycling and recovery.
What "zero waste to landfill" means
ZWL programmes typically require that a very high share of total waste — commonly 90% or more by weight, depending on the scheme level — is diverted from landfill and that diversion claims are backed by evidence from the facility gate to the final destination. Hazardous waste must still be managed through authorised routes.
The path to certification
- Waste mapping — list every waste stream: fabric cutting waste, yarn and thread, paper and cartons, plastic, metal, food waste, ETP sludge, chemical containers, e-waste and hazardous waste.
- Measure — weigh every stream consistently and reconcile with vendor receipts.
- Segregate at source — colour-coded bins, signage and worker training.
- Find destinations — recyclers, fibre-to-fibre recycling, co-processing in cement kilns and composting, each with documentation.
- Verify vendors — check licences and visit recycling sites to confirm what really happens.
- Certification audit — records review, site inspection and vendor traceability checks.
The hard streams
- ETP sludge — requires testing and an approved recovery route such as co-processing.
- Mixed packaging — multi-layer plastics have limited recycling outlets.
- Canteen waste — composting or biogas are good options.
Benefits beyond the certificate
ZWL programmes often generate revenue from segregated recyclables, improve housekeeping and fire safety, and strengthen the waste section of Higg FEM and ESG reports. Our Waste Management System training helps teams set up segregation and tracking.

Frequently asked questions
Does zero waste to landfill mean zero waste?
No. It means waste that is generated is diverted from landfill through reduction, reuse, recycling or recovery, at or above the threshold set by the certification scheme.
Does incineration count as diversion?
It depends on the scheme. Energy recovery such as cement kiln co-processing is often accepted within limits, while incineration without energy recovery usually is not.
How long does it take to achieve Zero Waste to Landfill?
Many facilities need six to twelve months of consistent measurement, segregation and vendor development before a certification audit.
