The Toronto Zoo is looking into using all that dung that they have and turning into electricity to help make the zoo carbon neutral.
Zoo board members heard that a digester big enough to produce 4 megawatts could power the zoo plus 15,000 homes in Scarborough.
The technology isn’t new. It’s used extensively in Germany, for instance. Staff told the board the process doesn’t involve incineration, and there’s no combustion.
It could be running soon and would reduce the zoo’s carbon footprint by 40 per cent, staff said.
The zoo keeps a large pile of animal waste on site, some of which is used as fertilizer. One by-product of a biogas facility could be a higher-grade fertilizer, which De Baeremaeker suggested could be sold.
