Soil Segregation, Recycling and Recovery

Reducing the ever increasing costs associated with transportation and landfill disposal whilst minimising the volume of contaminated soils requiring treatment ensures that careful soil segregation and recovery.

Churngold Remediation have established the minimisation of waste generation and maximisation of re-use and recycling as a key policy in its drive towards providing a sustainable and cost effective approach to site remediation.

Soil recovery and recycling not only removes the ever increasing costs associated with transportation and landfill disposal, it will reduce the volume of soils required for on-site treatment and reduce the need for importation of aggregates to replace soils removed from site for disposal with the associated cost benefits.

Soil segregation will allow the following range of options to be considered:

  1. Reuse onsite without further treatment
  2. Reuse onsite following treatment
  3. Reuse offsite without further treatment
  4. Reuse offsite following treatment
  5. Disposal to inert landfill
  6. Disposal to Non-Haz landfill
  7. Disposal to Haz landfill

Waste Identification, Classification and Site Waste Management Plan

Early identification and classification of the different waste streams on a site can allow the successful implementation of a Material Handling Strategy in accordance with the now compulsory Site Waste Management Plan. CRL can develop strategies that ensure that soils segregation processes are not restricted by a lack of room on site ensuring that sites can be recovered quickly and cost effectively in line with client’s objectives.

Selective Excavation and Segregation

Selective excavation and segregation of wastes into their various categories (Hazardous, Stable Non-Reactive Hazardous Waste, Non-hazardous, Exempt and Inert) minimises the disposal costs of soils required to be removed from site particularly where disposal to landfill is the only option eg basement excavations. CRL provide professionally qualified staff experienced in contamination identification and segregation practices.

Treatment of contaminated waste

As specialist remediation contractors, CRL are experts in the design and application of treatment technologies for the effective reduction of contamination levels found within waste streams on site. Hazardous wastes can be remediated to allow their retention on site or to produce reduced disposal costs. We will identify the most cost effective remediation technique suitable for the contamination profile and ensure remediation of contamination to established thresholds.

Re-using and Re-depositing material

The recovery, recycling and reuse of waste soils and aggregates is tightly regulated by the Environment Agency. Our in-depth knowledge and understanding of the regulatory processes and specifically exemption permitting requirements allows us to provide our Clients with fully compliant waste management strategies leading to limitation of any future liability.

In depth understanding of up-to-date guidance and codes-of-practice regarding the Environment Agency’s Definition of Waste, means that CRL have successfully negotiated the retention of hazardous waste on site where these soils are deemed to be fit for puropse for retention on site.

The Waste Resources Action Programme (WRAP) have developed guidance (the quality protocol) to help formalise the quality control procedure for the production of aggregates from recovered inert waste. Adherence to the standards and procedure set out within the protocol provide CRL with the capability to clearly assess and document that:

  • When an inert waste becomes a product (i.e. waste is fully recovered)
  • Recovered aggregate products conform to European and British standards

Where the Definition of Waste or WRAP Quality Protocol do not apply there are various other mechanisms available to ensure legal reuse and redeposit of waste

Waste Management Licence Exemption (onsite)

Certain activities are classified as exempt from control under the EPA 1995. Through successful application and negotiation of relevant exemptions through the Environmental Regulator, wastes may be re-deposited onsite without the need for any further waste management licencing. CRL are experts in the identification and agreement of these exemptions for a site as well having information databases to identify exempt sites in the local area capable of taking waste at cost effective disposal rates.
