Waste is hazardous when its composition or properties present a specific danger to people or the environment. All hazardous waste needs safe management.


It is important to create a traceable record of dates, addresses and times when waste leaves one site and arrives at another. We need accurate details of what is in the waste and the specific risk it presents. We also need the names and contact information of the people involved at each stage of the waste’s journey.

Departments need to keep copies of waste transfer notes (produced for all waste) and consignment notes (produced for hazardous waste only) for 3 years.

Any person or business involved in producing, storing, moving, recovering or disposing of hazardous waste must fill in the parts of the consignment note that link to their responsibilities.

Storage of records

You must keep copies of both the consignment notes and returns sent to you by the consignee (the recipient of the waste). This is a legal requirement and could be audited by the Environment and Energy Section, Safety Office, or Environmental Agency at any time.

More information on record keeping is available on our Duty of Care page.

Clinical waste

Clinical waste covers the disposal of any waste that consists of, or is contaminated with, human or animal tissue, blood or other bodily fluids or excretions, drugs or other pharmaceutical products, swabs or dressings, or syringes, needles or other sharp instruments, and any other waste arising from medical, nursing, dental, veterinary, pharmaceutical or similar practise, investigation, treatment, care, teaching, research or blood transfusion.
