Who it's for

These bags are ideal for the environmentally conscious UK dog owner who has a home composting system specifically for pet waste or uses a council-approved green waste scheme. They are also perfect for walkers who prioritise thick, opaque bags that eliminate the 'tactile' unpleasantness of waste collection while adhering to vegan and plastic-free lifestyles.

How it compares

How to use it

1. Pull a single bag from the recycled cardboard dispenser box.
2. Place your hand inside the bag, ensuring your fingers reach the corners.
3. Pick up the waste firmly using the bag as a protective glove.
4. Invert the bag over the waste, pulling the handles upward.
5. Tie the handles securely in a double knot to seal in odours.
6. Dispose of in a home compost bin designated for non-food plants or a dedicated dog waste bin.

As highlighted in reports by Ethical Consumer (2024), choosing home-compostable versions over oxo-degradable plastic is vital for preventing environmental contamination. Furthermore, testing by UK independent reviews (2025) suggests that cornstarch-based bags like these perform significantly better in puncture tests than standard recycled plastic variants.

FAQ

Can these bags go in my garden compost?

Yes, these bags are OK Compost Home certified, meaning they will break down at the lower temperatures found in domestic compost heaps. However, you should only use the resulting compost for ornamental plants and flowers, never for edible crops or vegetable patches, to avoid any risk of pathogen transfer from the pet waste.

Are they completely plastic-free?

Yes, they are 100% plastic-free and contain no polyethene. They are manufactured from plant-based materials including cornstarch and biodegradable polymers that convert into water, CO2, and biomass. This ensures that no microplastics are left behind in the soil after the decomposition process is complete.

How long do they take to decompose?

It depends on the conditions of your compost pile. In a well-maintained home compost bin with the right balance of heat and moisture, the bags typically break down within 90 to 180 days. In a commercial composting facility, the process is much faster due to the higher temperatures achieved in those environments.
