At King's, we aim to recycle 60% of our waste.

Recycling correctly can have significant positive environmental impact. Not only does it save resources, it also saves energy needed in producing items such as plastic bottles or drink cans.

You can help us achieve our target by following our Waste A-Z to learn about how to dispose of common waste types at King's. 

Aerosols

Reduce:

Opt for roll-on deodorants or pump sprays which use less packaging and are easier to recycle.

Reuse:

Consider creative DIY projects to repurpose empty cans, such as using them as holders for small items.

Recycle:

Check with local recycling guidelines. Empty aerosol cans can often be recycled with metals, but only if fully emptied and depressurized. 

Which bin?

Deodorant cans, air fresheners and spray paint are seen as potential hazards by some recycling facilities and should be placed in general waste.

Aluminium

Reduce:

Buy products in bulk to minimize the use of individual aluminium cans.

Reuse:

Use clean aluminium foil sheets for crafting or household tasks like lining pots for easy cleaning.

Recycle:

Ensure all aluminium cans are clean and empty before placing them in mixed recycling bins.

Which bin?

Aluminium cans are a valuable resource and should always be disposed of in mixed recycling bins. Aluminium foil should be placed in general waste.

Batteries

Reduce:

Switch to rechargeable batteries to cut down on waste and save resources.

Reuse:

Some stores and libraries have battery donation programs for partially used batteries.

Recycle:

Use the designated battery recycling bins across King’s campuses to ensure proper disposal.

Which bin?

Place used batteries in the special bins at each campus:

• Denmark Hill – Receptions of David Goldberg Centre; Henry Wellcome Building; Social, Genetic and Developmental Psychiatry Centre; Addiction Sciences Building; Institute of Psychiatry, Psychology & Neuroscience.
• Guy’s – New Hunt's House security and Hodgkin Building security.
• Strand – Receptions of Strand Building; Macadam Building; Maughan Library.
• Waterloo – James Clark Maxwell Building welcome desk and opposite G.20, Franklin Wilkins Building

Bags

Reduce:

Carry reusable cloth bags instead of opting for paper bags at stores.

Reuse:

Use old paper bags for crafts, wrapping gifts, or as compost liners.

Recycle:

Toss paper bags into mixed recycling bins if they are clean.

Which bin?

Clean paper bags should be placed in mixed recycling, soiled ones could go in general waste. For plastic carrier bags, see plastic bags.

Books

Reduce:

Use e-books or borrow from libraries to reduce the demand for physical copies.

Reuse:

Donate books to local charities, give them away within your department or take part in the King’s book swap programs.

Which bin?

If necessary, place it in the mixed recycling bin.

Bulky items

Please see 'furniture'

Cables

Reduce:

Minimise cable clutter by choosing wireless or multipurpose devices.

Reuse:

Repurpose old cables as plant ties, upcycle them into various products or donate them to e-waste charities.

Recycle:

Which bin? Dispose of cables via Waste Electrical and Electronic Equipment  (WEEE) recycling or e-waste bins available on campus. See WEEE pages (internal) for more information on collections.

Cans

Reduce:

Opt for drinks in glass bottles or reusable containers when possible.

Reuse:

Use cans for DIY plant pots or pen holders.

Recycle:

Rinse cans thoroughly before putting them in recycling bins.

Which bin?

Both steel and aluminium cans can be recycled, and unless specific bins are available, they should be placed in mixed recycling. Cans should be empty before disposal.

Cardboard

Reduce:

Avoid excessive online shopping to minimise cardboard waste.

Reuse:

Turn old boxes into storage containers, playhouses, or compost material.

Which recycling bin?

Use mixed recycling bins:

• Please make sure to flat pack boxes to save space in the bin, and ensure they are not taken out in the sorting process.
  
  
• We now have cardboard balers available at some buildings. If you are disposing of a large quantity of cardboard, please speak to a member of your local campus operations team.

Cartons

Reduce

Choose larger cartons over single-use portions to minimise waste.

Reuse

Rinse and use them as DIY seed planters for your garden.

Recycle

Flatten your cartons to save space and place them in bins.

Which bin?

Food and drinks cartons such as tetra paks should be placed in mixed recycling bins.

Cartridges

Reduce:

Switch to digital documents to print less and use ink more efficiently.

Reuse:

Refill your printer cartridges instead of buying new ones.

Which bin?

Please use the printer cartridge bins across King's campuses. If cartridge bins are not available at your site, take or send used printer cartridges to your local post room for recycling.

CDs/DVDs

Reduce:

Stream or download your media to cut down on physical discs.

Reuse:

Turn CDs into creative coasters or dazzling DIY decorations.

Which recycling bin?

Drop them in designated WEEE collection points for proper recycling. Please see the WEEE pages (internal) for more information on collections.

Chemical Waste

Reduce: 

Use only the required amount of chemicals to limit leftovers.

Reuse:

Share unused but safe chemicals with others in your lab or office.

Which bin?

Please refer to the information on the Health & Safety pages (internal).

Clinical Waste

Reduce:

Plan carefully to avoid overuse of single-use medical supplies.

Reuse:

If safe and permissible, use washable gowns or tools.

Recycle:

Segregate clinical waste for specialised disposal and energy recovery.

Which bin?

Please refer to the information on the Health & Safety pages (internal).

Clothes/Textiles

Reduce: 

Embrace a capsule wardrobe with versatile, high-quality clothing. Prefer thrifting over buying new products, boycott fast fashion brands such as Shein.

Reuse:

Wear what you own for as long as you can, try DIYing new styles on older garments and repurpose to the fullest! Donate clothes to charity or swap them with friends.

Which bin?

Drop off old textiles at designated recycling hubs. Clothes and textiles in good condition can be placed in on-street clothes/textiles recycling bins. Check your local council websites for more information.

Coffee cups

Reduce:

Use a reusable coffee cup to save money and the planet.

Reuse:

Some disposable coffee cups can double as seed starters for small plants—just poke a hole in the bottom for drainage.

Recycle:

Only the plastic lids of non-reusable coffee cups should be cleaned and placed into recycling bins.

Which bin?

Always place disposable coffee cups in general waste. Due to the waterproof polyethylene lining bonded to the cardboard, they need specialist processing and cannot be recycled through standard mixed recycling streams.

Computers

Reduce:

Opt for cloud storage to reduce the need for new devices.

Reuse:

Upgrade components instead of replacing the entire computer.

Recycle:

Use WEEE recycling points for safe disposal of computers.

Which bin?

Reuse:

Salvage bricks, wood, or fixtures for future projects.

Which bin?

Please refer to the Health & Safety pages (internal) for information on Site Waste Management Plans.

Crisp / Sweet Wrappers

Reduce:

Choose snacks with biodegradable or recyclable packaging.

Reuse:

Make DIY crafts like coin pouches or bookmarks.

Which bin?

The materials these are made from are not recyclable, as it is but a mix of foil and plastic, so these should go in the general waste. A good test if you’re unsure is to scrunch it up in your fist – if it doesn’t stay scrunched but pops back, then it isn’t foil and should go in general waste bin.

Use specialised bins for non-recyclable plastics where available.

Crockery

Reduce:

Invest in durable, high-quality crockery that last longer to avoid frequent replacements. Repair small cracks using food-safe adhesives.

Reuse:

Chipped plates and broken ceramics can be upcycled into mosaic art, garden decorations, or even unique jewelry.

Recycle:

Check the material of your crockery. Unlike glass, broken crockery can’t be recycled in standard recycling bins because it's made from ceramics, which melt at a much higher temperature.

Which bin?

Place broken ceramic crockery in general waste.

Reuse:

Use laminated sheets as dry-erase boards for lists or reminders.

Recycle:
