Walmart Donates Microturbines to Denver Zoo
Walmart is donating six microturbines from its experimental store in Aurora, Colo., to the Denver Zoo to help further its waste-to-energy system—a process that will convert the zoo’s animal waste and human trash into usable energy and heat. Walmart has been utilizing the energy generating units since 2005 as an experimental project to understand the thermal vs. electrical base loading of its buildings, as well as how co-generation might work on a Walmart store in the future.
The microturbines, valued at $1.2 million, will generate electrical energy to run the filters and pumps in the zoo’s 10-acre Toyota Elephant Passage exhibit and provide heat to endangered Asian species such as Asian elephants, greater one-horned rhinos and Malayan tapirs. Integration of the microturbine technology used in the Denver Zoo’s waste-to-energy technology was funded by Encana.
This is one of a number of sustainability practices at the Denver Zoo. It already has a sustainable management system in place, which provides an institutional-wide framework to identify, implement, measure, report and improve operations to reduce the zoo’s environmental impact.
