Hazardous Waste Treatment & Recovery Facilities
CSG owns and operates specialist hazardous waste treatment and recovery facilities across the UK. Our own treatment infrastructure, in-house chemists and nationwide collection services bring waste assessment, transport, treatment and reporting together through one coordinated service.
From packaged chemicals to bulk liquid waste, we assess each waste stream and confirm the appropriate processing requirements. Suitable wastes are received and treated at our own facilities, with technical oversight, acceptance checks and records covering their management.
Our hazardous waste specialists provide compliant collection, treatment and disposal solutions for organisations across the UK.
10%
of the UK’s hazardous liquid waste is treated by CSG.
THE EXPERTISE BEHIND THE PROCESS
Specialist knowledge behind every treatment decision
Our chemists and technical waste assessors review your waste, identify suitable treatment options and confirm acceptance requirements.
Where needed, we can arrange sampling or a site visit before collection to support accurate pricing and appropriate treatment.
Our Own Specialist Treatment Facilities
CSG-owned facilities provide specialist treatment and recovery processes for suitable hazardous waste streams.
On-Site Chemists
Our chemists support waste assessment, acceptance checks and treatment monitoring at our specialist facilities.
Waste Acceptance Checks
Incoming waste is checked against the agreed description and acceptance requirements before processing. Tanker loads undergo the relevant checks before unloading.
Treatment Records & Traceability
Waste documentation and relevant treatment and onward-movement records support a clear audit trail.
From Waste Assessment to Collection & Treatment
From the first assessment to the final checks, each stage has a purpose.
Assess
Our technical team reviews the waste, its source and supporting information. Sampling or analysis helps confirm suitable treatment and acceptance requirements where needed.
Check
Our receiving team checks incoming waste against its description and agreed acceptance requirements before unloading or processing, as applicable.
Treat & Recover
Suitable waste undergoes the appropriate treatment or recovery process at our facilities, overseen by our operational and technical teams.
Verify & Record
We record the waste’s management and arrange appropriate routes for recovered materials and treatment residues, including specialist onward processing where required.
A ROUTE SUITED TO THE WASTE
Hazardous Waste Treatment & Recovery Processes
Composition, contamination and recovery potential all influence what happens next.
Chemical & Corrosive Waste
Suitable wastes undergo controlled treatment to reduce hazardous properties or remove contaminants. This may involve neutralisation, separation and filtration, followed by appropriate management of the resulting materials.
Oily Water & Waste Oil
At our oil treatment facilities, suitable oily water and compatible industrial oil wastes undergo separation and treatment. Recoverable oil is prepared for further processing, while water and residual solids follow appropriate treatment or disposal routes.
Acceptance depends on the waste’s composition and condition. Highly flammable fuel requires a separate approved route and cannot be processed through our oil treatment plants.
Solvent Waste
Suitable solvents can be directed to authorised energy-recovery facilities. Other wastes may be sorted or dismantled so their recoverable components can be managed separately.
Recoverable Materials
At our specialist recovery facilities, we sort, dismantle, or process suitable waste to separate recoverable components. We then direct these materials to appropriate recovery or further-processing routes.
Waste Requiring Disposal
Some wastes and treatment residues cannot be recovered. We identify the appropriate disposal route and any treatment needed beforehand, explaining the proposed outcome.
Our Treatment & Recovery Facilities
Our treatment and recovery facilities form the operational backbone of CSG’s hazardous waste services. Each has defined capabilities, specialist personnel and waste acceptance requirements. Our technical team identifies the appropriate CSG facility according to the waste’s composition and processing needs, linking nationwide collection with our own treatment infrastructure.
Cadishead
Complex chemical waste treatment. Our primary facility for complex hazardous chemical waste, with permanent chemists supporting assessment, acceptance and treatment monitoring.
Blackburn
Specialist waste recovery. Sorting, dismantling and preparing materials for recovery, alongside hazardous waste consolidation and repackaging for specialist onward routes.
Teesside
Specialist waste processing and oil recovery. On-site teams support the repacking and processing of suitable waste streams, alongside specialist facilities for separating and recovering oil from compatible materials.
Oil Treatment Sites
Oil separation and recovery. Processing suitable oil and water mixtures, preparing recovered oil for specialist refineries and managing the remaining fractions appropriately.
Waste Transfer Sites
Local collection and onward transfer. Our waste transfer network connects local collections with specialist treatment and recovery facilities. These sites support controlled storage, consolidation and preparation for onward transport.
This infrastructure works alongside CSG’s treatment facilities, helping us coordinate the appropriate journey for each accepted waste stream.
Waste Treatment Records & Traceability
Appropriate documentation helps your business maintain an audit trail.
- Completed transfer or consignment notes, as applicable
- Relevant waste returns
- Records of onward waste movements
Digital Waste Tracking
Digital waste tracking is being introduced in phases. Reporting requirements for in-scope waste receiving sites in England and Wales took effect on 1 October 2026.
Existing waste transfer notes, hazardous waste consignment notes and relevant returns remain required where applicable. Our team will explain the information needed from your business and the records provided for your waste.
Hazardous Waste Treatment Facilities FAQs
Can you confirm acceptance before collection?
Our technical team reviews available information and may request Safety Data Sheets or representative samples. Sampling visits can be arranged where needed.
Is all waste treated at a CSG facility?
CSG treats suitable waste streams at its own specialist facilities. The receiving site and process depend on the waste’s composition, treatment needs and acceptance requirements.
Some wastes, recovered materials and treatment residues require specialist onward recovery, treatment or disposal at authorised external facilities. We explain the proposed route so you understand both our own processing activities and any further stages.
What if the waste differs from its description?
We raise a non-conformance, hold the waste separately and contact you to agree any treatment or price changes before processing. Return transport is chargeable if you choose to have the waste returned.
Does CSG own and operate its waste treatment facilities?
Yes. CSG owns and operates specialist waste treatment and recovery facilities, supported by our own operational teams, chemists and technical waste assessors.
This infrastructure allows us to carry out treatment and recovery processes ourselves for suitable waste streams, alongside our nationwide collection and waste management services.
Can CSG manage assessment, collection and treatment together?
Yes. We can coordinate waste assessment, collection, transport, treatment and reporting through one CSG service.
Our technical team confirms the waste’s requirements and proposed receiving facility before collection. Where further specialist processing or disposal is needed, we coordinate the appropriate onward arrangements and explain the proposed route.
