Food Waste (Including Tea Bags) – Place all food waste, including tea bags, in the designated food waste bin. 
Fridges/Freezers – To arrange a collection, email uk.uoc@tradebe.com. Ensure any necessary decontamination procedures for non-domestic appliances have been completed, and attach the appropriate Health and Safety Officer form directly to the appliance. 

Furniture 
Reuse is encouraged through the University’s internal reuse platform, Warp It. 
If reuse is not possible, here are companies that collect furniture: 

Furniture beyond repair should not be placed in trade bins but disposed of via a skip. Facilities Management can assist in arranging skip hire, including a Persistent Organic Pollutant skip at Laundry Farm to minimise disposal costs. 
Note: Waste produced by University departments is classified as 'trade waste' and cannot be taken to household waste and recycling centers. 
Ensure the following when disposing of furniture: 

  1. Obtain appropriate paperwork from the waste removal service to fulfill the University's duty of care and prevent fly-tipping. 

  1. Follow departmental procedures for asset disposal, particularly for high-value items. 
G
Glass – Place glass in the mixed recycling bin unless it is contaminated. For contaminated glass, contact uk.uoc@tradebe.com.

L

Lab Equipment (Misc.) 
Equipment no longer in use that is not classified as hazardous and complies with fire regulations should be offered to other University departments via the internal reuse platform, Warp It. The University's Equipment Sharing Project also enables sharing of underused equipment. 

For unused, obsolete, or broken lab equipment occupying valuable space, UniGreenScheme provides a removal and resale service. They collaborate directly with departments, collect and store items, resell them, and share a portion of the proceeds. 

Old or broken electrical lab equipment must be disposed of through the WEEE (Waste Electrical & Electronic Equipment) route. Use the relevant forms available on the University’s waste webpage. 

Lightbulbs 
Different types of lighting require specific disposal methods: 

  • Fluorescent lighting (glass tubes and compact fluorescent lamps): Contains mercury and must be disposed of as hazardous waste via Tradebe. Most University sites have coffin boxes for these bulbs. 

  • Filament bulbs: Dispose of in non-recycling bins. Wrap securely to prevent injury to waste operatives in case of breakage. 

  • LED lights: Classified as electronic waste and must be disposed of using the appropriate form available on the waste webpage. 
M
Magazines and Catalogues – Dispose of these in the paper/card bin. 
Media – For secure disposal of hard drives and data tapes, contact Shred Station or Restore Technology. This is a chargeable service billed to the department. For more information, reach out to Jamie Brittain in Facilities Management. 
Metal – To organise a metal skip, contact Facilities Management. Be cautious of businesses offering free scrap metal collection—verify their documentation via the Environment Agency's public register. 
Mobile Phones – The University's IT waste contractor can recycle mobile phones. Use the required form available on the waste webpage. Alternatively, defunct phones can be donated to charities like Little Lives Children’s Charity. 
N
Newspaper – Dispose of newspapers in the paper/card bins. 
O
Oil – Waste engine oil, machinery oil, or waste fuel oil produced by the University is classified as hazardous waste. It should be stored carefully in compliance with relevant legislation. To dispose of oil, contact UK.UoC@tradebe.com. Oily rags, oil drums, and other oil-contaminated items are also hazardous and should be treated accordingly. 
P

Paint – Community RePaint (https://communityrepaint.org.uk) is an award-winning initiative that redistributes usable paints to those in need, preventing unnecessary landfill. The nearest scheme is in March. Note: they do not accept paint thinners, strippers, varnishes, wood stains, or specialist paints. Paint 360 is another disposal option. 

If the paint is oil-based and in liquid form, it may be classified as hazardous waste due to its flammability. In this case, dispose of it as chemical waste via UK.UoC@tradebe.com. Ensure that containers are tightly sealed. 

To simplify disposal, separate water-based and oil-based paint wastes. Water-based paints are generally non-hazardous unless otherwise specified on the label. Dried or empty containers with water-based paint should be disposed of in the non-recycling bins. 
Paint Tins – If the packaging previously contained hazardous materials (e.g., paint tins, oil drums), dispose of them as hazardous waste via UK.UoC@tradebe.com. If thoroughly cleaned, they may be disposed of as non-hazardous waste in non-recycling bins, but the wash-water must be disposed of as hazardous waste. 
Pallets – Pallet skips are available at the following locations: Island site Addenbrookes, Old Addenbrookes site, Downing Site, Sidgwick Site, and West Cambridge site. A code is required to access these skips; please contact Facilities Management at facilities.management@admin.cam.ac.uk. 
Paper – Use the paper/card recycling bins for paper waste. 
Paper Towels – To be disposed of in the non-recycling bin.
Pens – Pens should be disposed of in the non-recycling bin. 
Pesticides – Unused pesticides, diluted pesticides, sprayer washings, and empty containers are hazardous chemical waste and should be disposed of via UK.UoC@tradebe.com. Minimise pesticide waste by estimating quantities in advance. Check with the supplier to see if they will accept return of empty containers; otherwise, thoroughly rinse and dispose of them as hazardous waste. 
Photographic Materials – Photographic processing generates a variety of chemical waste, which should be disposed of as chemical waste via UK.UoC@tradebe.com. 

Plastic – The best strategy is to reduce plastic use at the source. Consider switching to reusable alternatives or work with suppliers to reduce packaging. Some suppliers offer take-back schemes, including: 

  • Pipette Tip Wafers and Racks: Departments using disposable pipette tips can recycle the plastic wafers and racks. These are ground into polypropylene pellets and reused. STARLAB UK offers free collection containers and arrangements. A poster and bin label for this scheme are available. 

  • Expanded Polystyrene Boxes: New England Biolabs provides free return labels for these items. 

  • Coffee Pods: Nespresso offers 'take-back' collections for coffee machine pods. 

For general plastics: 

  • Plastic Bags/Wrap: Non-recycling bin. 

  • Plastic Bottles: Mixed recycling bin. 

  • Polystyrene: Non-recycling bin. 

  • Post-it Notes: Non-recycling bin. 
Printer Cartridges – Integrated printer cartridges can be collected with printers through the University’s approved IT items-only collection service with Restore Technology. The form can be found on the recycling and waste page. 
R
Refurbishment waste – If you have a building clearance, decant, refurbishment, or decommissioning project, you can add surplus assets to the University's Warp It system for redistribution. Warp It can manage the redistribution of assets both internally (where appropriate) and externally. For further options, refer to the "Furniture" section. 
Rubber bands – Place in the non-recycling bin. 
S
Sandwich boxes – Place in the mixed recycling bin. Any leftover food should be placed in the food bin.

Shredded paper – must be bagged and placed in non-recycling waste bin.
Stamps – Several charities accept used postage stamps to raise funds for their causes. Two examples include the Bone Cancer Research Trust, Kidney Care, and Canine Partners. 
Stamp pads – Ideally, stamp pads should be re-inked or refilled. If re-inking isn’t possible, dispose of them in the non-recycling waste bin.  
Stationery – If stationery is still usable but unwanted, consider advertising it on Warp It. To reduce waste, minimise the amount produced through careful stock control and ordering. Stationery amnesties can also help staff return unused stationery from desk drawers to a central location. 
Syringe bodies – Disposal via bmartyn@sharpsmart.co.uk. 
T
Tea bags – Place in the food bin.
Tetrapak – Empty and place in the mixed recycling bin.
