Disposal of waste chemicals, solvents and other hazardous substances.

Waste is hazardous if it contains substances that are harmful to human health or the environment. Hazardous wastes must not be disposed of in the general waste stream or via the drain; instead it must be segregated and disposed of/treated by an appropriate facility.

Disposal of hazardous wastes

The collection and disposal of solvents, chemicals and other hazardous waste is managed corporately by the Environment Officer. Collections are made by a specialist contractor approximately every two months – the collection dates are booked in advance.

Departments should book collections of waste as required using the booking sheet at least 8 days before a scheduled collection. Forms must be e-mailed to the Environment Officer; no additions can be made to the list once it has been sent.

Waste must be stored in line with legislation prior to collection for disposal.
