Waste exemption: T5 screening and blending waste
This exemption allows you to temporarily treat waste on a small scale to produce aggregate or soil at a place such as a construction or demolition site.
Types of activity you can carry out
- screening soil on a demolition site to remove wood and rubble before sending the soil to a construction site to be reused
- blending soil and compost that has been produced under an exemption on a construction site to produce better soil for landscaping on that site
- crushing waste (except bricks, tiles and concrete) before screening or blending
- grading waste concrete after it has been crushed to produce a certain type of aggregate
Types of activity you can’t carry out
- import waste, treat it and then export it somewhere else (this applies even if the treated aggregate would meet the Quality Protocol standard and will no longer be considered waste)
- treat waste where the main purpose is to dispose of it to landfill or incinerate it
- crush waste tiles, bricks or concrete (see related exemptions)
- treat hazardous waste

The amount of waste you can treat
You can store or treat:
- up to 50,000 tonnes of bituminous mixtures for making roadstone
- up to 5,000 tonnes of other waste under this exemption
over a 3-year period from the date of registering the exemption.
You can’t store waste for more than 12 months.
You can only treat waste at the place where it is to be used or where the waste was produced.
When you have treated the waste there are two options available:
- if the treated waste meets the requirements of a Waste Quality Protocol, it will no longer be considered waste
- use the treated waste under an exemption or permit when it has not met the requirements of a Waste Quality Protocol
These are related exemptions where you can use or treat waste:
- T7 – treating waste bricks, tiles and concrete by crushing, grinding or reducing size; you need to register this with your local authority, see full description in Environmental Permitting (England and Wales) Regulations 2010
- U1 – use of waste in construction
Register a T5 exemption
You need to register this exemption with the Environment Agency if you meet the requirements.
If you want to treat more than the amount of waste allowed under this exemption, you need to apply for an environmental permit.
If you want to import waste, treat it and export it elsewhere, you will need a site-based environmental permit.
If you want to crush bricks, tiles or concrete only, in amounts greater than the T7 exemption, you may need a Part B authorisation. Contact your local authority for more information.
