Denver Zoo ditches plans to convert elephant dung for electricity

By Bruce Finley and Kirk Mitchell, The Denver Post.

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.
