Secure destruction of hazardous waste


For waste streams that cannot be sustainably recovered or recycled, a high-temperature incinerator offers complete destruction whilst recovering energy as a result.

A high-temperature incinerator of this kind – also known as an energy recovery plant – harnesses the energy and heat as a result of the process, ensuring this waste disposal process falls into the ‘Recovery’ category of the waste hierarchy.

Operating at ~1050°C, we guarantee that your hazardous waste will be destroyed to form a non-hazardous byproduct, typically reduced in volume by 80%.

Additional benefits to the high-temperature incineration process includes:

  • Diverts large amounts of waste from landfill, minimising impact on the environment
  • A hygienic method of incinerating infected clinical waste as vectors and pathogens are destroyed
  • Produces less odour than landfills thereby reducing air pollution
  • Reduces the solid mass of the original waste to over 80% and volume by 95%

About Wastecare’s High-Temperature Incinerator


A high-temperature incinerator (HTI) of this kind, which combusts waste to produce electricity, is also known as an energy recovery or resource recovery plant. Our HTI currently harnesses 80% of the energy the site requires to run from the waste we incinerate.

Wastecare acquired the HTI in East Kent in 2019 and is one of only four of these plants in the UK. The site provides a controlled, secure disposal route for companies nationwide, whose clinical, confidential, and hazardous waste cannot be recycled.

The complexity of incineration process requires the Wastecare team to maintain, monitor, and make the incremental adjustments key to keeping the incinerator running optimally on a 24/7 basis. This includes monitoring the pollution control equipment, ensuring it does not exceed the limits set and regulated by the Environment Agency.

How our high-temperature incinerator works


Step 1

Processing temperature of the incinerator is 950 – 1050 degrees centigrade, maintained via feeding it solvents from our tank farm to increase the temperature, or an aqueous stream to lower it

Step 2

On-site chemists balance each waste load with a combination of material and chemical types. This ensures the kiln’s temperature doesn’t spike unexpectedly

Step 3

The waste is fed through the rotary kiln slowly to maximise the exposure of the solid waste to the high temperatures of the kiln

Step 4

The kiln’s flames and high temperatures convert highly hazardous liquids, sludges, and combustible solids into a gaseous steam

Step 5

The heat from this process is recovered to generate electricity – currently providing the entirety of our HTI site with 80% of the energy it requires to run

Step 6

The gaseous steam produced passes through the gas burner at the end of the kiln to break down the chemical bonds, to then recombine with the chamber’s oxygen supply to form a non-hazardous steam

Step 7

Fumes expelled are cleansed via an air pollution control system, before being discharged under a continuous monitoring regime controlled by the Environment Agency

Step 8

Any of the waste materials that have not been converted into gases (namely inorganic material such as metals), are discharged and removed at the end of the kiln for further treatment
