The Denver Zoo has halted plans for an innovative biomass gasification system that would have turned animal waste into energy — at least for now.
Zoo officials attributed the decision largely to a question of resources and money. They and prominent supporters acknowledged Friday that the system still faced a significant hurdle: getting the thing to work.
The zoo's announcement left room for an outside partner to revive the plans by helping with costs and know-how. But officials made clear that the gasification system would not operate on the zoo's campus, as had been planned.
