As part of the construction process, many developments will aim to re-use site won soils in the creation of the development platform, both as a sustainable and cost-effective exercise. IDOM Merebrook have a proven track record of producing Materials Management Plans (MMPs) which are compliant with the CL:AIRE Definition of Waste Code of Practice (DoW CoP) allowing our clients to maximise the re-use potential of suitable materials on the site of origin. An evidence-based approach is required to prevent excavated material from being classified as a waste by ensuring the following re-use criteria are satisfied:
• the use of the material will not create an unacceptable risk of environmental pollution or harm to human health.
• the material is suitable (chemically and geotechnically) for use without further treatment;
• there is a certainty of use for a material; and
• the material will only be used in the quantity necessary for that use.
MMPs provide a mechanism to re-use soils from both brownfield and greenfield sites on the site of origin and also enable the transfer of material been sites where a genuine need can be demonstrated. Provided the re-use requirements are met, and the MMP is in place prior to commencement of works, this activity can be undertaken without the requirement for an environmental permit. The value of a carefully considered, robust and evidenced MMP can be paramount for the financial viability of a project by demonstrating that the re-use of arisings from bulk earthworks and the installation of foundation and infrastructure are compliant with the requirements of the DoW CoP.
Our services include:
• Development of MMPs
• Support with tracking material movements on site
• Production of MMP validation reports
• Qualified person sign-off
Materials, including waste soils which are not to be retained on site, needs to be removed and disposed of in accordance with relevant statues. IDOM Merebrook can provide waste assessments which are tailored to individual site requirements. We design sampling strategies which allow for both horizontal and vertical delineation / segregation of materials according to defined waste acceptance criteria.
It is a legal requirement that waste sent to landfill is subject to measures to reduce the volume of material, reduce harmful or hazardous properties and facilitate recycling. These requirements may be satisfied by measures such as segregation and screening of wastes to recover suitable material for crushing as well as segregation of inert materials and putrescible wastes.
It is a common misconception that hazardous material must be removed from site. We aim to minimise the amount of hazardous waste requiring off-site disposal by using our expert knowledge and experience to correctly classify and determine the risk level associated with each type of material. We then use this information to design a strategy which directs material to the most appropriate areas for re-use on site according to the sensitivity of the proposed end-use. This ensures that higher rate material is retained on site (where chemically and geotechnically suitable) and that any material destined for landfill attracts the lowest possible disposal fee.
By combining our wealth of experience in materials management and comprehensive understanding of waste regulations, we support our clients through each stage of the process to fully realise the potential re-use opportunities on each individual site.
