Building a Future Without Waste
Key Features of Zero Waste to Landfill (ZWL) Certification
Zero Waste to Landfill Certification transforms waste management into a sustainable, circular system that maximizes resource recovery and minimizes landfill dependency.
Towards a Waste-Free Future
As industries expand and resources face increasing strain, effective waste management has become essential for sustainable growth and environmental protection.
- Establishes initial waste generation benchmarks and measurable diversion rate targets
- Encourages internal reuse and material exchange with partner organizations
- Promotes recycling, composting, and energy recovery through responsible waste management
- Recognizes performance levels — Baseline, Silver, Gold, and Platinum — based on verified diversion percentages

Key Focus Areas of Zero Waste to Landfill (ZWL) Certification
Zero Waste to Landfill Certification focuses on reducing waste generation, maximizing reuse, and ensuring that materials are diverted away from landfills through recycling and resource recovery. The certification helps organizations enhance efficiency, demonstrate environmental responsibility, and contribute to a circular economy.

Certification Benefits
Steps Toward Certification
 }})
Step 1: Application and Contract Review
Start your certification journey by submitting an application and reviewing the contract. This stage defines the scope, objectives, and documentation needed for assessment.
 }})
Step 2: Stage 1 – Desktop Review
Auditors review waste generation data, diversion plans, and supporting records to identify initial gaps and areas for improvement before the on-site audit.
 }})
Step 3: Stage 2 – Onsite or Online Audit
A detailed audit verifies waste reduction, reuse, recycling, and recovery systems. This stage confirms that your processes align with Zero Waste to Landfill requirements.
 }})
Step 4: Gap Closure and Certification Issuance
After addressing any findings, IRQS issues the Zero Waste to Landfill Certification, valid for 1 or 3 years, confirming your compliance and commitment to sustainability.
 }})
Step 5: Surveillance Audits (Year 1 and Year 2)
Annual surveillance audits ensure continuous improvement, ongoing compliance, and sustained performance in waste diversion and resource recovery.

Step 7 –Audit Planning and preparation
Prepare your audit plan with expert guidance to ensure a smooth certification process.
Steps Toward Certification
IRQS for Zero Liquid Discharge (ZLD) Certification
 }})
Join the movement toward sustainable water management with the IRClass – IRQS Zero Liquid Discharge Certification. This certification confirms your organization’s commitment to treating, recovering and reusing all wastewater, ensuring zero liquid discharge and protecting natural ecosystems. By implementing advanced treatment technologies and responsible sludge management, you reduce freshwater dependence, prevent pollution, and improve operational efficiency. ZLD Certification also strengthens regulatory compliance, supports ESG and sustainability goals, and enhances brand credibility.
Zero Liquid Discharge (ZLD)
- Reduce water acquisition cost and wastewater disposal risk
- Meet regulatory or supply-chain expectations in high-impact sectors
- Enhance your corporate sustainability credentials and stakeholder confidence
- Support operational efficiency by maximizing reuse and lowering fresh-water intake
- Defining the boundary, effluent streams and baseline for wastewater generation and reuse
- Documentation review of water/effluent flows, treatment systems, mass balance and reuse/recycle schemes
- On-site or remote audit of systems, controls, performance data and monitoring of discharge/reuse practices
- Verification that liquid discharge is effectively eliminated and all water is reused or safely managed
- Issuance of a certificate and supporting report confirming compliance and performance
- A formal ZLD Certification Statement or certificate issued by IRQS confirming your facility’s closed-loop water status
- A detailed assessment/report covering findings, audit evidence, improvements, and verification of zero liquid discharge
- Communication-ready materials (logo, certificate text) to showcase your ZLD commitment to stakeholders and supply-chains
- Water-use and wastewater-generation data (volumes, types of effluent)
- Treatment and reuse system description, flow diagrams, mass balance of wastewater streams
- Monitoring records of reuse, discharge (if any), and performance data of treatment systems
- Policies, roles and responsibilities for water/effluent management; internal audit and review records
- Evidence that no liquid effluent is discharged outside facility boundaries (or reused fully)
