Last year, some of the world’s most eminent biochar experts gathered for a biochar conference at the University of Massachusetts-Amherst to discuss this ancient technology that is getting a new look by scientists, governments and investors.

The city turned some of the debris into mulch, but launched a contest in October, Recycle Ike, to spark ideas for keeping the remaining tree waste from simply being disposed of in landfills.

The winners, announced last week, are a Rice University team of students and scientists who will create a biomass charcoal from the tree remains. The group was among more than 200 entrants from around the world that submitted ideas.
