It can be a minefield determining the most environmentally-friendly solution for your dog waste, but we’ve had a go for you!
When at home, the best solution is to set up a dedicated DIY compostor worm farm (Bokashi also have a neat system they call Ensopet), but don’t use this on your vegetable garden. Flushing down the toilet is a no-no according to Sustainability Victoria. Your general waste (landfill) bin should be a last resort.
When out and about, there are no perfect solutions. To be sure, the best option is to wrap in a compostable material (e.g. paper loo roll wrapper) and bring home to your dedicated compost. If using dog bags and Council bins, the waste will go to landfill so it’s important that the bags are “landfill biodegradable” (e.g. the BioGonebags used by Council).
While rates of degradation can’t be assured, they will eventually break down into harmless organic matter. Contrast this with “degradable” plastic bags which just break up into smaller plastic pieces! “Compostable” bags made from renewable bioplastics (e.g. corn starch) might be better again, but require a commercial composting facility to break down properly.
You’ll be pleased to know Council is considering this option with dedicated dog poo bins in our leash-free parks.
Whatever you do, don’t leave it behind (even in vegetated areas) because dog poo will release methane as it breaks down, and contains harmful bacteria that will pollute our waterways after the next rain. We hope this helps!
