Can Dog Poop Go in the Green Bin?
A carefully researched, authoritative, Ontario-focused guide explaining whether dog poop can be placed in municipal green bins, verified Durham Region rules, bag requirements, municipal policy variations, and proper waste sorting.
There Is No Single Green Bin Rule Across Ontario
Whether dog poop can go in the green bin depends entirely on your specific municipality and the technological capabilities of its organic-waste processing facility:
Accepted in Durham Region (must use 100% certified compostable bags), Toronto, York Region, and Ottawa.
Strictly prohibited in green bins in Peel Region and Halton Region, where pet waste must go into household garbage.
01Why Do Green Bin Rules for Dog Poop Vary?
Homeowners are often surprised to discover that a neighboring municipality accepts dog waste in green organic bins while their own city strictly forbids it. This variation is not an arbitrary administrative choice; it is driven by four primary operational, technological, and regulatory factors:
Some municipalities utilize high-temperature anaerobic digestion (AD) facilities or enclosed in-vessel composters capable of processing animal wastes and pasteurizing pathogens. Other municipalities rely on open-air aerobic windrow systems that operate at lower temperatures and cannot safely process animal fecal matter.
Cities like Toronto have installed heavy-duty hydro-pulping and hammer-mill depackaging equipment that strips traditional plastic bags from organic waste. Facilities without automated depackagers require either clean plant-starch certified compostable bags or paper liners—or prohibit bagged pet waste entirely.
Where finished organic matter is sold dictates input restrictions. For example, Halton Region produces Category AA compost for agricultural food crops, where strict Ministry standards limit heavy metals and fecal pathogens. Facilities producing industrial soil cover or renewable natural gas (biogas) have higher tolerance for pet waste inputs.
Ontario Ministry of the Environment, Conservation and Parks (MECP) Environmental Compliance Approvals (ECAs) set strict operational limits for individual processing plants, regulating odor management, vector attraction, retention time, and acceptable feedstock lists.
02Can Dog Poop Go in the Durham Region Green Bin?
Verified Regional SourceUnder the Regional Municipality of Durham’s updated waste management strategy (covering Pickering, Ajax, Whitby, Oshawa, Clarington, Scugog, Uxbridge, and Brock), pet waste—including dog feces and cat litter—is accepted in the Green Bin program for weekly curbside collection.
However, Durham Region enforces strict liner bag rules that every homeowner must follow. Failing to follow these containment guidelines will result in non-collection and a green sticker left on your bin.
Official Durham Region Containment Requirements:
- 100% Certified Compostable Bags Required: Pet waste must be contained inside a certified compostable liner bag or paper liner. Bins containing loose pet waste will not be collected.
- Approved Certification Logos: Look for bags certified by the Biodegradable Products Institute (BPI) or carrying the www.compostable.info logo (meeting ASTM D6400 or BNQ 9011-911 standards).
- Regular Plastic Bags Prohibited: Plastic grocery bags, traditional polyethylene dog waste bags, and non-certified oxo-biodegradable bags are strictly prohibited in Durham Region green bins.
- Weight Limit & Volume: Individual green bins have a maximum allowable weight limit of 20 kilograms (44 pounds) for weekly curbside pickup.
03Ontario Municipal Green Bin Comparison
To demonstrate why Ontario homeowners must check their own local guidelines, the table below compares official pet waste green-bin rules across representative Greater Toronto and Area (GTA) municipalities:
| Municipality | Pet Waste Accepted? | Bag Type Allowed | Official Primary Rule |
|---|---|---|---|
| Durham Region Pickering, Ajax, Whitby, Oshawa | ✓ YES | 100% Certified Compostable or Paper | Pet waste accepted as of July 1, 2024. Plastic bags prohibited. Loose waste rejected. |
| City of Toronto | ✓ YES | Any Plastic, Compostable, or Paper | Pet waste & cat litter accepted. Plastic bags stripped mechanically during depackaging. Park dog bins available. |
| York Region Markham, Vaughan, Richmond Hill | ✓ YES | Compostable, Paper, or Plastic | Pet waste & cat litter accepted. Certified compostable or paper liners preferred. |
| Peel Region Brampton, Mississauga, Caledon | ✕ NO | Garbage Bag Only | Pet waste prohibited in organics cart. Must be double-bagged in grey garbage cart. |
| Halton Region Oakville, Burlington, Milton | ✕ NO | Garbage Bag Only | Prohibited in GreenCart. Organics processed into Grade AA farm compost requiring strict pathogen limits. |
| City of Ottawa | ✓ YES | Sealed Plastic or Compostable | Pet waste & cat litter accepted in green bin. Must be sealed in leak-proof bags. |
Note: Sorting policies are established by individual upper-tier regional municipalities or single-tier cities. Always verify current sorting rules with your municipal waste authority before changing your disposal habits.
04What Kind of Bag Can You Use for Dog Poop?
Understanding bag materials is critical to maintaining green-bin compliance and preventing organic contamination. Dog owners encounter four distinct bag types on retail store shelves:
1. Certified Compostable Bags (e.g., BPI / ASTM D6400)
Required in DurhamMade from plant-based starches (corn, potato, cassava) combined with compostable polyesters (PBAT). Under industrial composting conditions (sustained 55°C heat, controlled moisture, and aerobic microbes), certified compostable bags break down completely into water, carbon dioxide, and biomass within 84 to 180 days without leaving synthetic chemical residues.
2. "Biodegradable" or Oxo-Biodegradable Bags
Not CompostableTraditional polyethylene plastic infused with chemical additives (like transition metal salts) designed to oxidize and fragment plastic under UV light. Oxo-biodegradable bags do not truly compost. They shatter into tiny persistent microplastics that contaminate compost and soil. They are prohibited in organic streams.
3. Regular Plastic Bags (Polyethylene / Grocery Bags)
City DependentStandard pet waste bags and shopping bags made from high-density polyethylene (HDPE) or low-density polyethylene (LDPE). Plastic does not break down in organic systems. While permitted in Toronto and Ottawa green bins (where depackaging machines strip the plastic), regular plastic bags cause severe contamination in Durham Region green bins.
4. Kraft Paper Liners & Paper Bags
Universally AcceptedUncoated paper bags and cellulose-based liners decompose rapidly alongside organic waste in all composting and anaerobic digestion facilities. They are accepted in every municipal green-bin program that permits pet waste.
05Can Biodegradable or Compostable Bags Go in the Green Bin?
A product being certified compostable in a laboratory setting does not automatically grant permission to toss it into your municipal green bin. Municipal green-bin programs enforce acceptance rules based on the entire waste package—both the bag and its contents.
Homeowners must check two distinct criteria before placing dog waste into a green bin:
Does the Municipality Accept Pet Waste?
If your city excludes pet waste (e.g., Peel Region or Halton Region), placing certified compostable bags containing dog poop in the green bin violates municipal sorting bylaws.
Which Liner Bags Are Permitted?
If your city accepts pet waste, verify whether it requires certified compostable bags (Durham Region), permits regular plastic (Toronto), or prefers paper.

06Why Some Facilities Accept Dog Waste and Others Do Not
The decision to include or exclude pet waste from an organic waste stream involves complex biochemical, engineering, and environmental management considerations:
Thermophilic Processing & Pathogen Destruction
Dog feces contains resilient pathogens like Salmonella, E. coli, Giardia, and roundworm eggs (Toxocara canis). High-tech thermophilic anaerobic digestion systems operate at temperatures exceeding 50°C to 55°C (122°F to 131°F) for extended retention periods, effectively pasteurizing pathogens. Standard windrow composting facilities operating at lower ambient temperatures cannot guarantee complete pathogen destruction.
Biogas Energy Recovery vs. Agricultural Compost
Facilities geared toward biogas recovery process organic slurry in sealed, oxygen-free digesters to produce renewable natural gas (methane) and electricity. In these systems, pet waste is a valuable organic carbon source. Conversely, facilities producing direct-to-farm agricultural compost avoid pet waste due to strict pathogen certification thresholds required for food crop fields.
07What Happens to Dog Waste at an Organics Processing Facility?
When pet waste is collected in an approved green-bin program, it undergoes an engineered industrial conversion process:
Collection & Receiving
Curbside trucks deliver green bin organics to a tipping floor inside a sealed, negative-pressure facility with biofilter odor scrubbers.
Pre-Treatment & Slurry
Waste is blended with liquid, screened for heavy contaminants, and agitated into a uniform organic slurry suitable for biological digestion.
Anaerobic Digestion
Methanogenic bacteria break down volatile solids over 15 to 30 days in sealed tanks, generating methane biogas for green power generation.
Curing & Soil Fertilizer
Digestate undergoes aerobic curing, pasteurization, and final screening to create nutrient-rich soil amendment for land reclamation.
08Green Bin Processing vs. Home Composting
It is critical to separate municipal green-bin processing from backyard home composting. Just because your city accepts dog waste in its green bin program does not mean you can safely throw dog poop into your backyard garden compost pile.
Municipal Organics System
- Industrial heating consistently reaches 55°C+ (131°F+)
- Sustained thermophilic temperatures destroy hardy parasite eggs
- Monitored pasteurization and controlled environmental isolation
Backyard Compost Bin
- Rarely reaches sustained high heat across the entire pile
- Roundworm eggs (Toxocara canis) can survive for years in cool soil
- Poses severe health risks if used on home vegetable patches

09Health and Pathogen Considerations in Pet Waste
Understanding why municipal organic programs enforce strict pet waste containment requires recognizing the biological hazards present in canine feces:
Bacterial Pathogens
Dog waste harbors bacterial strains including Salmonella, E. coli, and Campylobacter, which cause severe gastroenteritis in humans upon accidental ingestion.
Parasites & Protozoa
Organisms like Giardia lamblia and Cryptosporidium produce protective outer cysts that survive moisture and cold temperatures in outdoor environments.
Helminth Worm Eggs
Roundworms (Toxocara canis) release microscopic eggs that mature in soil, remaining infectious for months or years if uncontained.
10What Should You Do If Dog Poop Is Not Accepted in Your Green Bin?
If you reside in a municipality that excludes pet waste from the green bin (such as Peel Region or Halton Region), homeowners should follow approved municipal alternatives:
1. Regular Household Garbage (Double-Bagged)
The standard, legal method across all non-participating Ontario municipalities is collecting waste, placing it in a durable leak-proof bag, tying it securely, and setting it out with regular household garbage. Double-bagging prevents leaks and odor release inside garbage containers.
2. Flushing Raw Unbagged Waste Down the Toilet
Flushing raw, unbagged waste down a household toilet connected to a municipal sewer system sends waste directly to wastewater treatment plants designed for sewage processing. Never flush plastic or compostable bags or cat litter.
3. Professional Pet Waste Removal Service
For busy Durham Region homeowners who want a clean yard without hassle, Scoopwell provides professional weekly pooper scooper service, complete yard cleaning, and full compliance with municipal waste guidelines.
11Can You Put Dog Poop Directly in the Green Bin?
Homeowners must never dump raw, loose, unbagged dog feces directly into a municipal green bin. Every Ontario municipality that accepts pet waste requires waste to be contained inside approved liner bags (such as 100% certified compostable bags in Durham Region).
Dumping loose dog poop into a green bin creates severe sanitation hazards:
- Bin Sticking & Residue: Moist stool sticks to plastic bin walls and bottoms, preventing complete emptying during mechanical automated arm dumping.
- Severe Odors & Flies: Loose waste accelerates foul anaerobic odors, attracting blowflies, maggots, and rodents to your curb.
- Worker Exposure Risks: Uncontained pet waste creates aerosol splatter and health hazards for municipal waste collection crews.
- Curbside Non-Collection: Waste collectors will tag and reject green bins containing unbagged loose pet waste.
