How to Dispose of Kitchen Knives in the UK
Posted by Heinnie Haynes on 31st Oct 2025
Kitchen knives are everyday tools, but when they become damaged or no longer needed, they must be disposed of safely and responsibly. Throwing a knife into household waste can be dangerous for refuse workers and may break local disposal rules. There are several safe and legal ways to dispose of kitchen knives in the UK and we’re here to assist.
Can you put kitchen knives in the bin?
No, you should not put loose knives in household waste or recycling bins. Sharp blades can cut through bags and cause injury to anyone handling the rubbish. Instead, wrap or blunt the blade before disposal and use an approved collection point or recycling facility.
How to safely prepare a knife for disposal
Follow these steps to ensure safe handling before disposal or recycling:
- Wrap the blade securely
Use several layers of thick cardboard or newspaper and secure it with strong tape. Make sure no metal edge is exposed. - Blunt the edge if possible
Carefully dull the blade using a file or wrap the tip with additional cardboard to reduce risk. - Label the package clearly
Mark the parcel as “Sharp” or “Knives” so waste handlers know what is inside. - Do not leave knives outside or in public bins
Always take them directly to a recycling centre or collection service.

Can kitchen knives be recycled?
Yes Most kitchen knives are made from metal and can be recycled once made safe. Take them to a recycling centre and place them in the scrap metal container. Handles made from plastic or wood will be removed during processing.
Recycling your old knives helps recover valuable materials and reduces landfill waste.
What should you avoid when disposing of knives?
- Never place loose knives in general rubbish or recycling bins
- Do not post knives through letterboxes or leave them unattended
- Avoid giving knives to waste collectors directly unless clearly packaged and labelled
- Do not dispose of knives in rivers, fields or public places
Improper disposal could result in injury or even a police investigation if found in a public area.
Are there legal considerations when disposing of knives?
Yes. The same UK knife laws that regulate carrying and selling blades also apply to disposal. It is an offence to leave knives in public places or to give them to anyone under 18. Always transport knives securely, preferably in a box or bag, and go directly to the disposal point.
