Dog poop disposal needn’t be a mystery.
First, check how your region handles dog waste. Visit its website and search for “waste” or “garbage.” Maybe you’ll find a solid waste management plan. Each municipality will have a variety of suggestions and preferences (see this short list).
Choosing to bag Fido’s business in a biodegradable poop bag can be a “green” choice. Given the correct conditions, biodegradable poop bags will perform as promised. Note: Please remove as much air as possible before knotting the bag to prevent poop explosions that might propel contents onto workers or passersby when the bag is squeezed by the truck’s compressor!
Here’s the hitch. The conditions in landfills are anaerobic (devoid of oxygen) and anaerobic decomposition creates methane gas. Furthermore, poop in landfills can lead to water contamination which is why some landfills actually have a no-feces (dog or otherwise) policy. However, some regions permit very small amounts of well-wrapped or double-bagged dog poop in the garbage, especially in areas where there is no green bin collection. That’s not the best-case scenario, though, based on the above points.
Back to the question of disposal.
First of all, do pick up dog poop! The problems with leaving the poop to nature in high-density areas are:
- Dog poop is carried by storm water directly into waterways, where it causes bacterial contamination.
- It’s nitrogen-rich so it depletes oxygen levels, hurting fish and other wildlife.
- It’s unpleasant to step in.
Four responsible ways to keep doggie doo out of the landfill
With proper setup, composting is odour-free, yields rich soil and safely returns the poop to the earth. Popular home composting methods include:
- A compost pit — about one metre deep by one metre wide, with a cover.
- Dog poop compost bins — available at pet stores and garden centres.
- Vermicompost — create a separate worm bin from the red wrigglers that eat your organics.
- Digester — buried in your yard and works similar to a composter. Available at local stores or make your own.
Dog-waste compost should be kept separate from other compost and is best used on ornamental — not edible — gardens, and kept well away from streams, groundwater or vegetable and fruit crops. Avoid children coming in contact with dog poop compost due to risks of toxocariasis.
Do not flush any baggies — not even biodegradable bags! Scoop the poop directly into the toilet, empty the bags or wrap it in toilet paper before sending it down the pipes.
Compostable bags require the heat of a compost pile to break down. And beware of the word degradable (as opposed to biodegradable), which refers to formulated polythene. Polythene bags will fragment, not biodegrade, leaving tiny bits of plastic in the water.
Even bags labelled “flushable” will clog plumbing or the city sewer. Never deposit dog poop down the storm sewer either, as these often flow to our waterways (e.g., creeks and streams). On a septic system? Check with the installer or manufacturer.
3. Green bins
Municipalities, including Toronto and the Region of Waterloo, encourage dog poop disposal in the green bin (in certified compostable plastic or paper bags, or wrapped in newspaper or paper towel). More municipalities are making this change. Check with your municipal waste management department or request the change.
4. Private dog-waste-collection services
This can be a good option for multi-unit residences (townhouses or apartments) where a group of dog owners share costs. Have you spotted red collection bins for dog waste? In Vancouver, it’s a private dog-waste-collection company in action. Poop goes to the sewage-treatment plant.
