Chemical Waste Treatment and Recovery
CSG does more than collect and transport chemical waste. We treat approximately 10% of the UK’s hazardous chemical waste, with much of it managed at our Cadishead facility—one of the country’s largest hazardous waste treatment sites. Our specialists assess each waste stream and select the most appropriate treatment, recovery or disposal route.
- Advanced physicochemical treatment at our Cadishead facility
- Specialist treatment for water-reactive, oxidising and other complex wastes
- Recovery of metals from suitable liquid waste streams
- Solvent and high-calorific wastes routed for fuel or energy recovery where appropriate
Chemical Waste Guides & Advice
frequently asked questions about Chemical Waste Disposal
What is chemical waste?
Chemical waste includes unwanted chemicals and residues from manufacturing, laboratories and other activities. It may be hazardous or non-hazardous, depending on its composition and properties.
Can CSG collect both hazardous and non-hazardous chemical waste?
Yes. We collect hazardous and non-hazardous chemical waste, subject to assessment. Our team will review the composition, quantity and packaging to confirm acceptance and a suitable treatment, recovery or disposal route.
What kinds of chemicals can you process?
We can safely dispose of most types of chemical waste, including highly reactive and oxidising chemicals. Here are some examples of the kinds of chemicals we can remove and dispose of from your site:
- Acids and alkalis
- Metal complexes
- Cyanide and sulphites
- Sludges and suspensions
- Fuming acids such as oleum, chlorosulphonic acid and acidic solvents
- Water reactive chemicals such as thionyl chloride or phosphorus oxychloride
- Strong oxidising agents such as chromic acid, potassium permanganate and sodium hypochlorite
- Solvents
- Drums contaminated with water-reactive residues and other toxic chemicals
- Asbestos
Can you help reduce the environmental impact of our chemical waste?
We prioritise reuse, recycling and recovery where technically suitable and legally permitted. Some wastes require disposal. Our specialists assess each stream and explain the proposed treatment route and any residues requiring further disposal.
However, not every chemical waste stream can be recycled or recovered. Certain PFAS-containing wastes, for example, may require high-temperature incineration without energy recovery. Treating acidic or alkaline waste can also produce residues such as filter cake that must be sent to an authorised hazardous-waste landfill. The final route depends on the waste’s composition, contamination and available treatment options, and we will explain the proposed outcome before collection.
What information do you need for a quote?
To provide you with an accurate quote, we’ll require you to share the following:
- Safety data sheet (if available)
- UN number (if known)
- Waste composition (If the composition is unknown, tell us. We can advise on identification, sampling or analysis before confirming acceptance and collection)
- Volume
- The packaging the waste is contained in (e.g. small containers, drums, IBCs, in bulk liquid form)
- Location and accessÂ
Do you provide containers/drums/IBCs or advice on packaging?
Yes. We’re happy to advise on suitable storage and packaging for chemical waste. If you need replacement containers, let us know and we can also provide these at an additional cost during your waste collection.
What are your minimum collection quantities?
CSG provides hazardous waste disposal services for commercial and industrial customers, so our collections are generally best suited to businesses with larger quantities of waste or regular disposal requirements.
Our minimum disposal charge is £150, excluding VAT, consignment note and transport fees. Because of this, we may not be the most cost-effective option for very small quantities of domestic hazardous waste, such as individual tins of paint, household chemicals or small DIY waste items.
If you are a business and are unsure whether your waste meets our collection requirements, please get in touch with our team. We can advise on the most suitable and cost-effective disposal option based on the waste type, quantity, packaging and location.
Can you collect out of hours or to site permit restrictions?
Most chemical waste collections take place during normal operating hours. However, we may be able to accommodate specific access, permit or operational restrictions on a case-by-case basis. Availability depends on factors including the waste type, site location, transport requirements and receiving facility opening hours.
For urgent incidents outside normal working hours, our emergency spill response service may be able to assist. Please tell us about any restrictions when making your enquiry so we can confirm the available options.
What happens to chemical waste after CSG collects it?
Each waste stream is assessed according to its composition, hazardous properties and recovery potential. It is then directed to an appropriate treatment, recovery or disposal route, with much of the waste managed through our specialist Cadishead treatment facility.
What is physicochemical treatment?
Physicochemical treatment uses controlled chemical and physical processes to reduce hazardous properties and separate contaminants. Depending on the waste, this may involve neutralisation, oxidation, reduction, controlled dissolution, precipitation or filtration.
Can chemical waste be recovered rather than disposed of?
Where technically viable, we prioritise recovery. Metals may be recovered from suitable liquids, while solvent-based and high-calorific wastes may be directed to specialist fuel or energy-recovery routes. Not every waste is suitable, so each stream is assessed individually.
How do you decide which treatment route to use?
Our specialists consider the waste’s source, composition, hazardous properties, physical form and recovery potential. Sampling or additional analysis may be required where the composition is complex or information is incomplete.
Can CSG treat reactive or complex chemical waste?
Our facilities can manage a range of complex wastes, including certain water-reactive and oxidising materials. Acceptance is subject to a specialist assessment to confirm compatibility, packaging requirements and the safest treatment route.
