Today’s Solutions: October 22, 2021

Garbage trucks in Toronto will soon become cleaner – that is, environmentally speaking – as the city has recently launched an initiative to power the vehicles using biogas produced from the very trash they collect.

Starting in March 2020, the city’s fleet of garbage trucks will collect all of the organic waste and food scraps from the Toronto Green Bins and bring them to the facility for processing. The facility will then use anaerobic digesters to capture all of the biogas produced by the waste and transform it into renewable natural gas (RNG).

After the scraps are dropped off at the facility, the city’s 170 garbage trucks can then immediately fill up their fuel tanks with RNG before heading out to collect more trash.

Apart from being more environmentally friendly, RNG is also less expensive than fossil fuels, such as diesel. Once injected into the natural gas pipeline, it can be used to fuel vehicles and even heat people’s homes.

This closed-loop system is just one of the city’s four pre-planned waste-to-RNG production schemes for the coming years.
