If your activity is eligible for a waste exemption, you must generally register it with the Environment Agency. However, Local Authorities register two types of waste treatment activity: Treating waste metals or alloys by heating to remove grease, oil or any other nonmetallic contaminant (also called a category T3 activity); and Treating waste bricks, tiles or concrete by crushing, grinding or size reduction (also called a category T7 activity).
More about T3 and T7 activities
T3 activities are the treatment of waste metals for the purposes of removing grease, oil and any non-metallic contaminant by heating in an appliance. To qualify as a T3 exempt waste operation the activity must also meet the following criteria:
- The total quantity of waste stored at any one time must not exceed 10 tonnes;
- The waste must be stored in a secure location with sealed drainage;
- The appliance (or aggregate of all appliances used together) must be less than 0.2 megawatts net rated thermal input; and
- It must not be used for the removal of plastic and rubber from scrap cable or any asbestos contaminant.
T7 activities involve the treatment by crushing, grinding or reducing in size of concrete, bricks, tiles and ceramics or mixtures of these materials (other than those containing dangerous substances, i.e. ‘170106 mixtures’). Such T7 activities typically involve the use of small-scale/micro crushers and can include some mobile plant. It is an exempt activity ONLY if it satisfies ALL of the following specific conditions:
- No more than 20 tonnes of waste are treated over any period of one hour;
- No more than 200 tonnes of waste are stored at any one time;
- The waste is stored in a secure place (i.e. non accessible to the general public and from where waste cannot escape) prior to processing;
- The treatment is carried out at the place where the waste was produced OR at the location where the processed material is to be used;
- Any release of substances into air is trivial, i.e. will not cause pollution or will cause an insignificant pollution.
Operators of T3 and T7 facilities must also satisfy the general conditions of being carried out with the purposes of recovering the waste and without causing harm to human health and/or the environment.
