UK2 - Preliminary Market Engagement Notice
Summary of the contracting process

The Mining Remediation Authority is planning a procurement for the "Remediation of Metalliferous Mine Waste," focusing on services related to contaminated soil, under the industry category of environmental remediation services. The project, based in multiple regions across the United Kingdom including UKC, UKD, UKE, UKK, and UKL1, is currently in the planning stage with potential engagement from interested organisations invited until 12th December 2025. The market engagement notice was published on 18th November 2025 and the formal tender is anticipated to be announced by 22nd December 2025. The contract period is expected to begin on 1st April 2026 and conclude by 31st March 2031, involving an innovative, proportional suite of techniques to stabilise mine wastes.

This tender presents significant opportunities for businesses specialising in environmental and soil remediation, particularly those capable of developing bespoke solutions tailored to complex ecological conditions. Small and medium enterprises (SMEs) may find this an attractive opportunity, given the suitability considerations stated in the notice. Firms with expertise in mining waste management, ecological restoration, and technosol development that can contribute to mitigating diffuse pollution and enhancing river catchment health will likely be well-positioned to compete for and benefit from this contract. The contract's focus on innovative and comprehensive approaches to remediation highlights a preference for entities that can provide both expertise and creativity in addressing these environmental challenges.

Notice Information

Notice Title

Remediation of Metalliferous Mine Waste

Notice Description

Addressing metalliferous diffuse pollution from old, abandoned metal mine sites within UK river catchments is a priority due to the significant environmental impacts associated with the release of harmful diffuse pollutants. These mine sites both leach toxic metals like lead, cadmium and zinc and mobilise heavy metal containing sediments that are washed/leach into adjacent watercourses. This contamination impacts water quality, aquatic life and biodiversity. Proactively managing and mitigating diffuse pollution in these catchments is essential to restoring and preserving the ecological balance of the river systems, ensuring the safety of the water for future generations, and maintaining local economies that depend on both rivers and surrounding lands for employment, recreation and agriculture. The primary objective under this contract is to mitigate diffuse metalliferous pollution within complex topographic and ecological conditions by applying an innovative, proportional suite of techniques to stabilise mine wastes and interrupt erosion and infiltration pathways. Baseline data on soil chemistry, metals and microbial diversity will inform the design of multi-treatment trials to evaluate restoration materials and techniques across contrasting environmental conditions. We will be looking to consider a range of stabilisation methods, including bespoke technosols to be developed to address the diverse on-site substrates; bare spoil, early-stage biocrusts and spoil adjacent to established habitats. The approach will be sympathetic to natural ecological succession from primary non-vascular colonisers to mature native grassland and heathland communities.
