## Summary

The Nuclear Decommissioning Authority (NDA) has completed its procurement process titled "Cementitious Materials for Waste Encapsulation". This contract, categorised under research and development services and related consultancy services (CPV 73000000), primarily focuses on services related to waste encapsulation. It follows a limited procurement procedure without prior publication, as it is a call-off from an NDA Framework and falls outside the scope of standard EU directives. The contract, valued at GBP 549,630.03, was awarded to NSG Environmental Ltd. The procurement was finalised and the contract signed on 5th March 2025. The delivery location for the project is within the UK.

This tender presents an excellent opportunity for businesses involved in waste management, research, and material sciences, particularly those that specialise in the development and application of cementitious materials. Companies with existing frameworks with the NDA or those familiar with bespoke, high-stakes projects in nuclear site management would find this contract advantageous. Moreover, smaller enterprises with innovative solutions and competitive pricing had a chance to compete, as indicated by the received bids, which included at least one from an SME. Businesses aiming to engage with governmental contracts, especially ones pivoting towards sustainable and safe waste management practices, could benefit significantly from such opportunities.
