Green Bin Frequently asked questions

If diapers and personal hygiene products can't go in the green bin, why is pet waste acceptable?

Diapers and personal hygiene products contain plastic and absorbent material that can't be processed and are not accepted at the facility in Guelph.

Pet waste is on their approved list of materials. Temperatures in the compost facility are high enough to kill any pathogens that may be present. All finished compost is tested and has to meet Provincial standards before it can be sold.

I use my backyard composter, why do I need to use a green bin?

Thanks for composting at home! We encourage you to handle your own waste in a backyard composter, if you choose.

Backyard composting can complement the green bin. Items, such as meat, bones and sauces that can attract critters are accepted in the green bin.

Some residents using backyard composters choose to take a break over the winter and use the green bin while their composters are buried in the snow. 

For residents who don't have the space or desire to compost at home, the green bin provides a great way to reduce their garbage.

I'd use my green bin if only I could put plastic in it. Why can't we?

Regular plastics, including plastic grocery bags and packaging, aren't accepted in the green bin because they are not allowed in the processing facility in Guelph. 

Good news! Certified compostable plastic bags that display one of two approval logos (below) are acceptable! More information about certified compostable plastic bags is available.

How did you estimate the amount of green bin material that could be collected?

Waste audits were conducted. We collected garbage placed at the curb in randomly selected neighbourhoods across the Region, and sorted the contents into over 60 categories. The audit results estimated that 50,000 tonnes of potential green bin material was going to the landfill. 

If everyone used fully used their green bin, the amount of residential garbage going to landfill could be cut in half!
