Cleaning and sterilising waste medical instruments containing metal for recovery: RPS 160

Updated 30 October 2023

Applies to England

This regulatory position statement (RPS) does not change your legal requirement to have an environmental permit for a waste operation to clean and sterilise waste medical instruments containing metal. This applies to both single use and end-of-life multiuse instruments.  

However, the Environment Agency will not normally take enforcement action against you if you do not comply with this legal requirement provided that: 

  • your activity meets the description set out in this RPS  

  • you comply with the conditions set out in this RPS 

In addition your activity must not cause (or be likely to cause) pollution of the environment or harm to human health, and must not: 

  • cause a risk to water, air, soil, plants or animals 

  • cause a nuisance through noise or odours 

  • adversely affect the countryside or places of special interest 

1. Activity this RPS applies to 

This RPS applies to the cleaning and sterilising of waste medical instruments containing metal coded 18 01 03* (infectious waste). This will allow the waste metal to be sent for metal recovery rather than sent for treatment or incineration. The waste codes after treatment will be 18 01 01 (if sharps) or 18 01 04 (non-sharps).  

2. Conditions you must comply with 

You must: 

You must not treat more than 1 tonne per day. 

3. When you must check back 

The Environment Agency intends to review this RPS by 1 August 2026. 

The Environment Agency can withdraw or amend this regulatory position before the review date if they consider it necessary. This includes where the activity that this RPS relates to has not changed. 

You will need to check back from time to time, including at and before the review date, to see if this RPS still applies. 

This RPS remains in force until it is removed from GOV.UK or is otherwise identified as having been withdrawn. 

4. If you cannot comply with this RPS 

If you operate under this RPS but can no longer comply with it, you must stop the activity to which this RPS relates and must tell the Environment Agency immediately. Email wastetreatment@environment-agency.gov.uk and put ‘Cleaning and sterilising waste medical instruments containing metal for recovery: RPS 160’ in the subject.
