Architecture students from around the world participated in the recent Concrete Thinking for a Sustainable World Competition. Co-sponsored by Portland Cement Association and the National Ready Mixed Concrete Association, and hosted by Association of Collegiate School of Architecture, 800 students from 33 architecture schools either created an environmentally responsible recycling center, focused on reusing today's materials to preserve tomorrow's resources, or designed a building element that provides a sustainable solution to real-world environmental challenges.

Antonio Vigil of the University of New Mexico won first place in the recycling center category for his interesting blend of programmatic elements built around the prominent sustainable theme “reduce, reuse, recycle.” His recycling center was located in a central shopping area and included a local market or “mercardo” for people to sell and exchange goods. Jurors also noted Vigil's innovative use of concrete and the integration of the parking lot to reduce site coverage.

The building element category was won by Anne Miller from the University of Toronto, who explored the minimal use of materials, resulting in a reusable fabric concrete formliner.

Winning students, their faculty sponsors, and schools will receive cash prizes and software totaling nearly $50,000. Additional winners and their projects can be found at
