TDG Environmental's water recycling and material recovery operations transform environmental waste streams into valuable resources. Through our resource consented Mainstream Recycling facilities, we process and repurpose up to 98% of collected waste materials, creating a sustainable circular economy that reduces landfill dependence whilst meeting all environmental compliance requirements.
Increasing Disposal Costs
Traditional landfill disposal creates escalating costs whilst contributing to environmental degradation and limited resource availability.
Regulatory Compliance Requirements
Meeting Resource Management Act 1991 and local council requirements for waste minimisation and environmental responsibility demands proven solutions.
Resource Conservation Pressures
Organisations face mounting pressure to demonstrate environmental stewardship and reduce their ecological footprint through waste reduction.
Limited Recycling Infrastructure
Many regions lack specialised facilities capable of processing stormwater, street sweeper, and non-destructive digging wastes effectively.
Our resource consented facilities employ sophisticated separation technologies to process multiple waste streams. We handle stormwater waste, street sweeper materials, and non-destructive digging mud through mechanical and hydraulic separation systems. These processes isolate recyclable materials whilst removing contaminants to meet environmental standards.
Processed materials separate into three valuable product streams for beneficial reuse. Sand materials meet specifications for construction and landscaping applications. Organic soils provide nutrient-rich additives for horticultural and landscaping purposes. Aggregate materials support civil engineering and landscaping projects requiring quality fill material.
Our combination jetting and vacuum units incorporate advanced water recycling systems for operational efficiency. These units continuously capture, filter, and reuse water during pipeline cleaning operations. This technology dramatically reduces potable water consumption whilst minimising wastewater requiring offsite disposal.
All processed materials undergo testing to verify they meet quality standards and environmental requirements. We maintain comprehensive documentation for regulatory compliance and traceability. Our processes align with Waste Minimisation Act 2008 requirements whilst supporting your organisation's sustainability objectives.
Proven Track Record
With 30+ years of environmental services experience, TDG Environmental brings deep understanding of New Zealand’s regulatory landscape and environmental challenges. Our team understands the complexities of waste processing, from initial collection through to final product delivery, ensuring reliable service delivery.
Resource Consented Operations
Our facilities hold full resource consents for waste processing and recycling operations. This demonstrates our commitment to environmental compliance and operational excellence. We maintain all required permits and regularly update our systems to reflect evolving environmental standards.
Circular Economy Leadership
By transforming waste into resources, we help organisations demonstrate environmental responsibility whilst reducing costs. Our approach keeps materials in productive use, reducing demand for virgin resources. This circular economy model aligns with New Zealand’s sustainability goals and provides measurable environmental benefits.
Technical Expertise and Equipment
Our specialised processing equipment and experienced operators ensure maximum recovery rates from every waste stream. We continuously invest in technology upgrades and operator training to maintain industry-leading performance. Our facilities can handle varying waste characteristics and volumes efficiently.
We process stormwater waste, street sweeper materials, and non-destructive digging mud at our resource consented facilities. Our systems handle various contamination levels and material characteristics. We can assess your specific waste streams to confirm suitability for our processing systems.
Our facilities achieve up to 98% recovery rates, converting collected waste into sand, organic soils, and aggregates for beneficial reuse. Recovery rates vary based on waste composition and contamination levels. We provide detailed reporting on materials processed and products generated from your waste streams.
All processed materials undergo testing to verify they meet specifications for their intended applications. We maintain quality control procedures throughout processing operations. Products comply with relevant environmental standards and performance requirements for landscaping and construction applications.
We supply comprehensive waste tracking documentation from collection through to final product delivery. Our records demonstrate compliance with Resource Management Act 1991 and local council requirements. Documentation includes waste manifests, processing reports, and product quality certificates as required.
Our on-unit water recycling systems dramatically reduce potable water consumption during pipeline cleaning operations. This decreases water supply costs whilst minimising wastewater disposal volumes and associated fees. Many operations report 70-80% reductions in water-related costs.
Our systems handle varying contamination levels, though heavily contaminated materials may require pre-treatment or alternative disposal methods. We assess waste characteristics before processing to determine appropriate handling procedures. This ensures optimal recovery rates whilst maintaining product quality standards.
Recycled products supply the landscaping industry for various applications including soil conditioning, fill material, and aggregate needs. We work with landscaping suppliers and contractors to ensure materials find productive reuse. This creates local circular economy benefits within your region.
Yes, we offer comprehensive waste collection through our resource consented vehicle fleet. Our combination vacuum and jetting trucks collect waste from stormwater systems, GPTs, and non-destructive digging operations. We coordinate collection schedules to align with your operational requirements.
