Hazardous Waste Rules for the Workplace

UK workplaces that produce or hold hazardous waste have responsibilities for its classification, description, transfer and records. The exact requirements depend on the waste and the nation in which the site operates.

The GOV.UK hazardous waste guidance summarises the requirements for England and links to the separate arrangements in Scotland and Wales. This article provides general information for commercial sites and does not replace site-specific professional advice.

The GOV.UK waste duty of care overview states that businesses must keep waste to a minimum, sort and store it appropriately, complete transfer documentation and use authorised carriers and sites.

The duty follows the waste through its transfer. An accurate description allows the carrier and receiving site to determine whether they are authorised to handle the stated waste.

Chemical waste is assigned a List of Waste code, also known as a European Waste Catalogue (EWC) code. The classification is based on the waste’s source, composition and hazardous properties.

The Environment Agency’s WM3 waste classification guidance provides the technical method. A Safety Data Sheet (SDS) can support the assessment, but it describes the supplied product and is not automatically the complete classification of the resulting waste.

A business can allocate internal responsibility for maintaining waste information, arranging collections and retaining documentation. This does not transfer the producer’s legal responsibility, but it can make records easier to manage across departments or sites.

Collection records identify the producer, carrier, waste description, quantity and receiving site. Hazardous waste movements use consignment documentation, while other controlled waste movements use the relevant transfer documentation.

The Health and Safety Executive explains that Safety Data Sheets provide information about chemical hazards, handling, exposure controls and emergency measures for supplied substances and mixtures.

This article does not provide instructions for handling a particular substance, responding to a spill or treating an exposure. That information must come from the SDS and the workplace’s competent safety arrangements. Emergencies should be directed to the emergency services.

Waste classification and transport classification are related but separate. Where a load is dangerous goods for transport, the Department for Transport guidance explains the framework commonly known as ADR.

Chemical Disposal uses ADR drivers where required. The waste description, SDS, EWC code, quantity and container details allow the transport requirements to be reviewed before a vehicle is arranged.

Chemical Disposal cannot collect or accept unidentified or unknown chemicals. The first stage is to provide any available information, such as the source, process, original product label or SDS, so our team can review it.

If further identification is required, testing or analysis can be arranged only by agreement with the customer. A collection can then be considered after the waste has been identified and classified.

Before quoting or collecting, Chemical Disposal requires an SDS for each product or substance and an assigned EWC code for each waste stream. We also request the quantity, container type, full collection address and photographs of the waste and labels.

Collections may cover several identified streams, including solvent waste, laboratory waste and liquid chemical waste. Each stream is reviewed separately even when they are collected together.

Our team reviews the collection details and confirms whether any further information is required. Once the waste and collection requirements are clear, a quote can be prepared.

Chemical Disposal is a licensed waste carrier. Waste is collected using an ADR driver where required and transported to a licensed disposal site in our network. We do not treat the waste.

For information about a particular workplace collection, contact the Chemical Disposal team with the SDS and assigned EWC code for each waste stream. We can review the details without giving chemical, legal or safety advice.
