If you could design an XPRIZE for waste and the circular economy, what would it be?

At Visioneering 2019, participants will pitch ideas for prize competitions in this domain to accomplished CEOs, world leaders, philanthropists, influencers and thought leaders.

Visioneering is an annual event for benefactors, where attendees help XPRIZE refine and iterate how we tackle global challenges, learn from one another about breakthrough efforts being conducted around the world, and hear and experience new exponential technologies that are reshaping society and helping to generate an abundant future for all.

You can get involved as well! Click on "New Discussion" to pitch your own idea for an XPRIZE. The top prize ideas will be shared with the crowd at Visioneering.

The author of the best prize idea will win tickets to an exclusive XPRIZE event on October 5: an evening of dinner and dancing under the lights of the La Brea Tar Pits at the limited-time architectural creation, Second Home Serpentine Pavilion, in Los Angeles.

Submissions are now closed. The winner will be announced soon.

De-constructible Construction

Our current construction practices are out of date. Today we are building using the same techniques we developed centuries ago. Sure, we have refined our technologies but we are still building with cement, wood, etc and using the same details. Our typical wall assembly includes so many sealants and glues that it's impossible to take it apart after construction. The number one barrier to a circular economy in the built environment is de-constructability. Modular construction, though faster and sometime cheaper, hasn't been able to scale and replace conventional stick-built construction.

This is a challenge to design a system for a fully de-constructible/circular office building - no wet-applied coatings, no sealants, no glue, using conventional building materials (no shipping containers, etc..). The de-constructible office building *must* meet all codes, be fully water-proofed, provide ulterior energy performance, be constructed in the same or faster time frame as a conventional building, cost no more than a conventional building, and be able to be FULLY taken apart in the same time frame as a typical demolition job. Construction AND Demolition of this building would result in ZERO waste to landfill.

If every building was built to be de-constructed, we would relieve the world of 50% of its current solid waste, and of the need to produce 870 tons of materials per second for the next thirty years.
