About Us

About Us

Castle Environmental is a leading supplier of specialist waste treatment, disposal and recycling services. Established more than 35 years ago, we handle in excess of 250,000 tonnes per year of wastes.

We have fully permitted sites at Ilkeston, Stoke-on-Trent and Cardiff which enable us to provide nationwide services for the removal of a wide range of hazardous and non-hazardous wastes such as acids, alkalis, contaminated effluents etc. We are ISO 14001 and 9002 accredited and are active members of the Environmental Services Association.

We are committed to reducing dependence on landfill based disposal routes. As one example, we have achieved the relevant 'end of waste' criteria for the incorporation of washed air pollution control residues in our manufacture of precast concrete blocks.

We have a dedicated Research and Development team who focus on recycling/recovery options for a variety of wastes.

Recycling

Recycling

We are market leaders in the recycling of air pollution control residues (APCr).

With the removal of WAC derogations from all hazardous waste landfills in the near future and the statutory requirement to consider the waste hierarchy, volumes of APCr routed to recycling outlets will have to increase.

For more than 4 years we have processed APCr so as to facilitate incorporation into a variety of construction products. We have achieved the relevant 'end of waste' criteria for the incorporation of washed APCr in our manufacture of precast concrete blocks (if you have an interest in purchasing such blocks please contact us for a quote).

We operate other recycling/recovery processes - for example, our electrolysis plant recovers copper from aqueous wastes and we recycle ferric chloride into a number of outlets.

Treatment

Treatment

Our waste treatment sites at Ilkeston, Stoke-on-Trent and Cardiff enable us to provide nationwide services for the safe removal of a wide range of wastes including incinerator fly ash/air pollution control residues, acids and alkalis, solvents and flammable materials, contaminated packaging/PPE, oxidising solids, organic acids (and other high BOD/COD aqueous wastes), ammoniacal and amine wastes, contaminated effluents/leachates, epoxy resins and hardeners, aqueous cyanide wastes - and hypochlorite effluents.

Waste Collection

Waste Collection

We use a large network of third party hauliers for the collection and transport of all the wastes that we handle - including bulk liquids, powders (tankers and bagged) and containerised wastes - drums, IBCs and other packaged wastes.

Also, we work with an established number of carefully selected third party recycling/disposal sites so that we can provide a full service for the widest possible range of wastes.
