Materials Management Plans (MMP)

Roberts Environmental Materials Management Plans (MMP)

A Materials Management Plan (MMP) sets out how excavated soils and other site materials will be handled, reused, and managed during construction or remediation works. Prepared in accordance with the CL:AIRE Definition of Waste Code of Practice, an MMP demonstrates that materials are suitable for their intended use and can be reused on-site or between sites without being classified as waste. By carefully planning material reuse, an MMP helps developers comply with environmental regulations, reduce landfill disposal, lower costs, and support more sustainable construction practices.

Talk to our Experts

01. Understand your site

Materials Management Plans (MMPs) are generally required when undertaking earthworks or remediation to manage soil movement on brownfield or greenfield sites.

They reduce the requirement for soil disposal and importation, lowering carbon emissions, noise, and your costs whilst contributing to sustainable development.

Our experts start by reviewing all previous documents, discussing requirements with you and understanding your site and proposal. We can then start producing your MMP.

02. Avoiding Legal Action

Changes to landfill tax rules in 2025 mean that developers which reuse materials without an appropriate environmental permit, waste exemption or Materials Management Plan in place, risk significant fines and tax payments.

We will help you avoid these penalties by providing advice throughout the development and identifying the evidence required to demonstrate;

There is a need for the material;
The material is suitable for its intended use;
The volume require is reasonable for its use.

03. Developing a Materials Management Plan

We develop Materials Management Plans which provide all of the required lines of evidence to prove a material is not waste.

An MMP must be completed prior to materials being excavated and we recommend it is developed at the earliest possible stage of project planning, evolving with the design.

MMPs allow materials to be re-used legally, without risk of future regulatory enforcement and the associated financial penalties.

04. Qualified Person Review and Declaration

On completion of the MMP, our registered CL:AIRE Qualified Person will review the Materials Management Plan to confirm it has been fully completed and prepare a declaration for submission to CL:AIRE.

Following completion of works on site we prepare a Validation Report which is submitted to CL:AIRE.
