How to Dispose of Your Pet Waste

by Ivan Zeng, Communications Assistant

Going Zero Waste is all about learning how to make little changes in everyday life that can have a positive impact in the long run. One challenge many of us can relate to is pet waste removal and disposal. According to the Humane Society, nearly half of households have at least one dog. If you pick up dog waste 3 times a day with plastic bags, that’s over 1000 bags a year into the landfill! Have you ever wondered how else you can dispose of your pet waste that is more sustainable? We have! And for a ‘zero waste’ solution, we have put together a few tips for you!

Our Top Choice: Flush them

Flush them! You can flush your pet waste straight down the toilet. The Region’s wastewater treatment system is designed to treat these kinds of wastes.

Another Alternative to the Garbage

The Green Bin

Putting your pet waste to your green bin is the best way to divert garbage from our one and only landfill in the region. If you receive weekly curbside green bin collection service in your neighbourhood, add pet waste to your green bin.

When adding the pet waste to your green bin, be sure to wrap them fully in newspaper or paper towelling, or place in a paper bag. This is to ensure the health and safety of your waste collection crews.

Decide on the Type of Liner Bags

  1. Paper. All paper liner bags are acceptable and do not require any special certification or logo, or
  2. Certified compostable plastic (CCP) liner bags. Only use certified compostable plastic bags which have one of following COMPOSTABLE logos:

One Last Alternative to the Garbage

Digest them in your backyard

Did you know you can bury pet wastes in your backyard? Pet wastes can be buried in your backyard using a digester. And you can find digesters available at local stores or even make your own. Our staff Cheryl Evans shares her experience on making your own backyard digester.

Here’s Cheryl’s story:

“Try Making Your Own Pet Waste Digester In order to try to out the most environmentally responsible pet waste option, that uses no water or fossil fuels and produces useful compost, I decided to build a backyard pet waste digester. No rocket science here! My digester is a modified garbage can with a lid that is sunk into the ground.

  1. Get a garbage can with a removable lid.
  2. Cut out the bottom with a jigsaw.
  3. Drill holes in a 6” grid patter along the sides of the can.
  4. Dig a hole in the ground just a little wider and shorter than the can.
  5. Sink the can so that only the lid is showing.
  6. Backfill between the earth and outside of the can with gravel or soil.
  7. Add pet waste.
  8. Add a septic starter to get going”


Some Tips for Success:

  1. Use a dedicated composter for pet waste only
  2. Use septic starter to speed the breakdown process
  3. Keep at least 2 metres from food waste composter
  4. Don’t use plastic (even bio bags) in the composter
  5. Mix layers of wood chips, saw dust or dried plant material to help the digestion process  and reduce moisture build up and odours smell

In two years, the compost should be ready and you can use the resulting compost material as a soil amendment to spread around your property’s lawn and gardens.

Important note: to avoid the potential for spreading harmful diseases, pet wastes should be digested separately, such as away from food waste composter. Avoid planting anything over the site for at least two years or spreading digested pet wastes on vegetable gardens.
