Today’s Five Friday Facts deal with the Denver Zoo’s new Elephant Passage complex which is slated to earn LEED certification. Read more about the zoo’s efforts to reduce their footprint in yesterday’s post.
The following facts come from the Denver Zoo.
- In preparation for the new LEED certified exhibit, the zoo developed a functioning, portable demonstration gasification system in 2009. The unit was at 10kW prototype, which consumed approximately 20-30 pounds/hour of biomass. The unit was developed to help Denver Zoo understand operation of gasification before building the larger scale unit associated with the Toyota Elephant Passage exhibit.
- Every day, Denver Zoo produces an average 4,200 pounds of general waste (food waste and trash left by visitors), which goes to a landfill, and 2,700 pounds of animal waste that currently is composted.
- Preliminary estimates indicate that the conversion of zoo waste into usable energy could save as much as $150,000 a year in energy costs.
- Denver Zoo’s landfill contributions will be reduced by 1.5 million pounds per year, putting the zoo a giant step closer to becoming a “zero-waste” facility.
- The gasification system will convert more than 90 percent of the zoo’s waste into usable energy.
