Biffa Waste Services Limited - Trecatti Landfill, Trecatti Landfill Site, Fochriw Road, Merthyr Tydfil, CF48 4AB

We’ve received an application to vary an environmental permit from Biffa Waste Services Limited. Substantial variation to an environmental permit under the Environmental Permitting (England and Wales) Regulations 2016

Application number: PAN-026599

Regulated facility type:

The primary activity of this installation is the Section 5.2 Part A (1) (a) disposal of waste in a landfill activity.

The permit also allows the following relevant activity to take place:

  • Section 5.3 Part A (1) (a) (ii) recovery of hazardous waste with the capacity exceeding 10 tonnes per day involving physico-chemical treatment of asbestos contaminated soils (asbestos picking station)

The following activities are being varied/added.

Regulated facility location: Trecatti Landfill, Trecatti Landfill Site, Fochriw Road, Merthyr Tydfil, CF48 4AB.

The facility currently permitted to treat hazardous waste soils for recovery via

  • Biological treatment of hazardous and non-hazardous waste
  • Physio-chemical treatment for asbestos picking.

This variation is to broaden the permitted treatments to be carried out on hazardous waste soils to enable them to also treat soils with hazardous levels of metals, hazardous levels of asbestos fibres, and wastes deemed hazardous by other means such as pH.

The annual throughput for soils contaminated with Asbestos will remain 25,000 tonnes per annum. But the Operator wishes to increase the annual throughput of hazardous waste soils deemed hazardous by other means from 30,000 tonnes per annum to 40,000 tonnes per annum.

The Operator outlines I the proposal that the new treatment will utilise the existing plant and equipment on site and will not require any additional pollution control measures.

The application contains a description of how the proposed changes will affect the installation; the materials, substances and energy it will use and generate; the conditions of its site; the source, nature and quantity of its foreseeable emissions and their potential impact, the proposed techniques for preventing, reducing, and monitoring its emissions and preventing and recovering waste; and an outline of the main alternatives, if any, considered

You can see the application documents free of charge, from our online public register. Or you can request a copy of the information from us. This may take time to process and there could be a charge.
