5 Ways to Recycle Dog Poop (& Why You Should Do It)

Hiking or simply walking with your dog is one of life’s great pleasures. But picking up the inevitable poop? Not the fun part, but a small price to pay as a responsible partner of your furry friend.5 Ways to Recycle Dog Poop (& Why You Should Do It)

You always carry pick-up bags and never fail to stoop and scoop. Commendable! You’re keeping walkways, landscape and watersheds clean. But when you pick up your doggie deposit and toss it in the nearest bin, do you ever have a fleeting feeling that this is not the most environmentally friendly disposal option, asks Rose Seemann.

All garbage not separated for recycling is hauled to sanitary landfills where it is preserved for generations. When sealed up in this plastic-lined bin without air or moisture, organics don’t rot and cycle back to the earth as they would in nature.

In addition to occupying precious landfill space, organic waste slowly emits methane, a powerful greenhouse gas. That’s why the push is on to compost food scraps and garden clippings or use them as an energy source. But what about your dog's poop? Surely there’s not enough of it for concern.

Ah – but if we’re aiming for sustainability, there surely is! According to the RSPCA, the U.K. is home to 8.5 million dogs and an equal number of cats. The dogs alone produce more than a million tonnes of waste per year, enough to fill 10 average soccer fields three meters deep.

While country dogs are free to distribute their droppings widely like scat, their city cousins’ poop is concentrated around spaces shared by humans. With nearly 800,000 dogs in the capital, London spends £9.5m annually on sending their waste to landfill.

Most urban dog waste ends up shrouded in plastic bags. Don’t fall for the hype that compostable or biodegradable bags will help its contents turn to soil like apples and autumn leaves. Landfills seal off all the elements necessary for degradation in the 21st century. And every tonne of excrement locked underground produces 450kg of greenhouse gases that are piped into the atmosphere.

While local jurisdictions are inching their way toward a zero waste economy, communities are not likely to turn their attention to mitigating dog poop trash anytime soon. So if you’re looking for green do-it-yourself choices, what do you do with the doo?

Well, simply flushing works. There are, of course, drawbacks, such as the need to carry waste to the nearest toilet. But with a bit of research, you can find flushable bags that dissolve on the way to the treatment plant. If you decide to go this route, here are a few tips:

- Try not to overfill the bag or you’ll bung up the plumbing. If you own a Baskerville Hound, you might need to use two bags.
- Flushable bags can begin dissolving on long walks. Take along a waterproof container for transport.
- Don’t flush into residential septic tanks not connected to a septic sewage system. Dog hair will clog underground emitters that release waste water into the soil.

Another easy solution is burial. Select a spot away from sensitive areas such as streams, wetlands, wells, tender new plants and vegetable gardens. Stay away from foundations, walls or fences that might be affected by unstable moist soil.

Dig your hole or trench at least 20 cm deep so that the waste will not mix with cover topsoil, attract wild animals or be disturbed by people or pets. Allow the buried material to rest for six months, then plant grass, flowers of shrubs above the site. Manure contains ammonia and salt, so make sure new roots are surrounded by good topsoil and positioned to grow down toward the canine cache.

Another option is burying dog poop sparsely in small, deep holes in soil around well-established ornamental woody plants and along the perimeter of tree canopies. Be careful not to disturb the roots. These pockets of fertilizer will decompose, eliminating the harshness of raw manure so that the nutrients can be taken up by plant roots.

Have you considered adding dog poop to your compost pile? Many health authorities discourage the practice, but if you have the basics of composting down to a knack, consider dog poop as an effective nitrogen (green) source. Just don’t add it to a working batch that will be used in edible gardens.

Whether raw or casually composted, carnivore manure can contain stubborn pathogens that pose health hazards if they directly contaminate harvested fruits or vegetables. So it’s important to use it as a soil amendment only around ornamental plants.

If you normally compost to enrich an edible garden, you can create a second pile to accommodate dog poop. Be sure to use separate tools to avoid cross contamination. For step-by-step instructions, search online for “USDA: Dog Waste Composting,” which documents the process used at dog sled yards in Fairbanks, Alaska.

Installing a doggie septic bin is a good option for dog owners with limited outdoor space. Simply cut out the bottom of an old plastic garbage can and drill a dozen or so drainage holes in the sides. Select a spot away from water sources, walls and foundations. Then dig a hole deep enough to bury the can to an inch below the rim.

The Dog Poo Wormery

Worms are Nature’s natural recyclers and eat all manner of material, mostly green waste such as fallen leaves as well as faecal waste from animals such as badgers, foxes, deer etc and yes, they even eat dog Poo. Might not sound so great to us but worms do actually like it.

5 Ways to Recycle Dog Poop (& Why You Should Do It)

Worms like to eat most things that are naturally biodegradable and in doing so they convert it to a natural fertiliser which can be used in the garden.

The Dog Poo Wormery comes in various sizes so you can get the correct size wormery for the number of dogs you have. Best of all, there is virtually no smell from the wormery at all!

Toss in some rocks or gravel for drainage and place a lid on top. Now you’re ready to start scooping poop into your bin. Each week sprinkle in some water and septic starter available at hardware stores. The waste will degrade, shrink in mass, enter into the subsoil and leave a residue. You can either remove the can and bury the residue or use the material to fertilize non-edible plants. Visit cityfarmer.org/petwaste.html for a guide and videos.

Finally, you can feed dog poop to worms. Yes, they will turn it into rich vermicompost if their menu does not include more tantalisng entrees. If you’re feeling adventurous, you can start a dedicated worm farm in your basement or even under your sink. But describing all the steps for this more complicated process would, at this point, be like (uh) opening a can of worms. But if this solution is appealing, a few online searches will set you on your way.

  1. Hello Rose, I enjoyed your article and believe your book must be an excellent source of information for people that want to recycle their dog waste. Although I think that any attempt to recycle pet waste is commendable I definitely prefer to convert dog poop with the help of compost worms.

    As a dog and cat lover as well as a commercial worm farmer I have recycled all my pets waste as well as that of others for many years now safely in worm bins. I am so glad that the idea of composting pet waste is slowly catching on as I was ridiculed many times over the years when I stated that recycling dog poop is a viable option when it comes to deal with the waste of our best friends. I truly hope that your book will spread widely and that you will inspire many more to convert their pet poop into nutrient rich plant food.

    Kind regards

  2. Hi! Great ideas of the worm eatery! I will check this out! I am definitely up for doing something with all of this waste! Tidbit on flushing! EPA says please no flushing or placing pet waste into any water source that can cross contaminate other main sources of water. Good luck pet owners

  3. Hi there, I see this is a very old article but hopefully you note my reply , which is really more of a question: I love the idea of the dog poo wormery, but live in South Africa so can’t just buy one… where do I get more info? It is seems to be just a standard wheelie bin (dustbin), with a tap and a cover over the extraction hole – but how do I get started and what sort of worms does one use? Earthworms?

  4. I bought a home a few years ago and I had a nice size yard with an extra piece of parcel land that was not being used. I had one dog so the poop was always tossed close to a big tree that was close to the edge of the perimeter of yard, this went on for years. Well…the years past and from one dog four more came along throughout the years. I finally decided to excavate that piece of land and to my surprise when my husband started to dig next to the tree where the poop had been tossed…the amount of poop accumulated throughout the years looked like it was fresh potting soil from the store…no smell, nice in color very soft….just like potting soil, that we used it to mix it with the regular soil and it turned out very well. I was very pleased. So it’s true what they say. Use your dog poop.

  5. Hello, I have a worm bin that I have for dog poop. It works great. All I do is put leaves, poop, a small amount of food scraps with the worms (Red wiggler worms) and in 6months I have great soil. I call it black gold. I got the worms on line and love those little guys. They do a great job.
    But I love all your ideas!!
    Thanks for your help. Dana
