DHI Environmental

Non-hazardous Sludges

Nationwide non-hazardous sludge treatment & tanker collection

DHI Environmental provides nationwide collection and treatment of non-hazardous sludge streams, including interceptor waste, tank clean-out residues and effluent treatment plant sludge generated through routine operations and planned preventative maintenance (PPM).

Collected via vacuum tanker, non-hazardous sludge is processed through mechanical dewatering and separation systems to reduce volume, maximise recovery and minimise landfill disposal.

Need non-hazardous sludge collected?

Our national treatment network ensures efficient routing and cost-effective waste management for operational sites across the UK.

Why use DHI for Non-hazardous Sludges?

Efficient Tanker Collection

Scheduled and responsive tanker services tailored to routine maintenance and operational requirements.

Volume Reduction Expertise

Mechanical dewatering processes designed to minimise disposal volumes and optimise treatment outcomes.

Recovery-Focused Solutions

Where possible, sludge fractions are diverted toward recovery and reuse rather than landfill.

Nationwide Treatment Network

Access to licensed facilities across the UK ensures consistent service delivery and efficient routing.

Our Process

Our streamlined sludge processing approach focuses on volume reduction, recovery and efficient nationwide treatment.

Collection & Facility Allocation

Tanker-collected sludge is assessed and directed to an appropriate licensed treatment facility within our national network, ensuring efficient routing and practical cost control.

Dewatering & Volume Reduction

Mechanical dewatering separates solid and liquid fractions, reducing overall disposal volumes and preparing materials for recovery or compliant discharge.

Recovery & Reuse Routes

Where viable, separated materials are directed toward recovery, reuse or compliant discharge pathways, supporting landfill diversion and sustainable waste management.
