We are searching for topics and funders for the next Longitude Prize. This idea is a draft for discussion about one possible prize focus that we are exploring.
What is the problem?
Construction materials are historically designed with a finite lifespan, destined for eventual obsolescence and replacement. This linear “take-make-dispose” model drives continuous resource depletion, as even “sustainable” materials eventually degrade and require the manufacturing of new replacements.
Why does the solution contribute to solving this?
By rethinking the chemical and structural makeup of building blocks, we can create materials designed for indefinite lifecycles. This eliminates future construction waste entirely and ensures that the footprint of building a home is a one-time ecological cost rather than a recurring environmental burden.
Who is the prize awarded to?
Awarded to the team that develops a viable construction material or modular building system that can be reconfigured or regenerated indefinitely without loss of structural integrity, demonstrating the feasibility of constructing a complete dwelling exclusively from these closed-loop, permanent components.
The best prize ideas are developed through extensive research and engagement with experts, stakeholders and people with lived experience of the problems they are focused on. We start with a first draft like the one above – then work to improve, refine and validate our thinking. If you are interested in sharing your expertise, or helping us secure funding for the next Longitude Prize, please reach out.
