A MRA was conducted by Material Index at the iconic DUKES Hotel located in St James’ Mayfair, prior to its refurbishment. The 93 key hotel had a large variety and quantity of assets, including furniture, lighting and sanitaryware, which was captured in the audit.

Considering a short time frame and difficult site access, the exchange team successfully found reuse pathways for 285 assets, with an estimated equivalent of 182 tonnes (182,107 kgs) CO2e. 

Material Index is proud to have enabled circular economy practices at this iconic London establishment.

Material Index conducted a MRA of 1 Knightsbridge Green instructed by project managers Blackburn & Co’s, which included a material brokerage service. The shared aim of Material Index and Blackburn & Co was to maximise reuse of materials during the demolition process.

Material Index, with assistance from ‘Contrakt’, the strip-out contractors team on site, facilitated the collection of materials from 1 Knightsbridge Green over a period of four months. Materials that had reuse potential were catalogued within the MI platform during the MRA. There was a wide range of materials captured within the audit, so the exchange team decided to group asset types for sales outreach and targeted specific partners within our network to maximise reuse results.

These headline figures show the success of the project. We were able to add value to the project, generating increased revenue for the client and diverting materials from typical recycling/waste pathways. The benefits of MI’s hands-on approach was reflected in orchestrating 14 different collections from site.

Material Index conducted a Material Reclamation Audit (MRA), and brokering services, of 1 Knightsbridge Green. Instructed by Blackburn & Co, over £8,000 was returned to client and an estimated Carbon saving of over 60 tCO2e.

Formerly the headquarters of BP, and more recently John Lewis; 171 Victoria Street was designed and oriented around a single occupier. MI was engaged by Savills to conduct a thorough Pre-Demolition Audit to capture all materials left on site, and assess the reusability.

The proposed scheme is to re-purpose the existing building to be a more sustainable, modern destination with greater flexibility for multiple tenants. In collaboration with KpH, the on-site strip out contractors, Material Index has facilitated 6 material exchanges with our various trade partners, with over 12,000 carpet tiles, 582 ironmongery items and 113 other assets sold and reused (as of April 2025). 

This is another great example where the appointment of Material Index on a project truly accelerates material reuse at scale.
