Innovation Challenge 2020 Project Diamond


“The response to our innovation challenge from both existing and future suppliers has been remarkable. All of the ideas we received have challenged us to think differently and puts us firmly on the path to Net Zero.”

Jonathan Harry, procurement director

As part of our 2020 Innovation Challenge, we have called on our suppliers and partners to develop and share ideas that contribute to a reduction in industry carbon emissions. The challenge builds on the success of our inaugural Innovation Challenge in 2018, which generated over 200 bold new ideas that drew on the knowledge and experience of a variety of experts throughout Tarmac’s supply chain.


In 2020, the focus has been on ideas which support the continued drive to reduce carbon across the industry, following the UK becoming the first major economy to commit to achieving a net zero society by 2050. This legislative commitment requires action from public and private organisations to allow for the development of a greener, cleaner society – the built environment will be key in meeting the challenge.

Despite the COVID-19 pandemic, we had 174 ideas submitted from our supply chain, start-ups, scale-ups, SMEs and other organisations. 57 percent of the ideas we received came from new contacts that we have made through this process. The ideas were then filtered to 124 to understand what ideas are applicable and impactful to our business. From those 124, 40 were selected to be developed further by the supplier and our category management team to understand the project potential.

Eight ideas were shortlisted to for further development in the business. These projects are of course at different degrees of implementation, with some fully in place and others needing more work to ensure a successful roll out. They all meet our objective collaboration with our supply chain to significantly reducing carbon in our operations and are scalable across our business.
