Don’t Throw Away Your Dog’s Poop for This One Reason

Australia has one of the highest rates of pet ownership in the world, with 38% of Australian households owning dogs. Dogs improve the quality of our lives, and studies show that exposure to dogs can even improve our immune system.

However, one medium-sized dog produces about 180 kilograms of poop a year. With about 9 million dogs in Australia, it can really start to pile up.

Rather than wrap it in plastic and throw it away — where it eventually ends up in landfill — you can use dog poop as a sustainable source of fertilizer.

Poop Problems

The waste products of humans and their associated animals have not always been a problem. In the past, even within the memory of people I met living on small Pacific islands, human poop was produced in relatively small amounts because the population was low, and could decompose naturally and safely within the soil. Healthy soil contains a vast number of microbes and organisms that thrive on organic material.

But burgeoning populations have changed this. Waste produced by humans is now an immense problem. Not only is there a waste issue, but human activities have caused soil pollution and degradation that kills soil microbes or impairs their capacity to process organic matter.

Dog poop is considered an environmental hazard. This is a consequence of its composition. It is comprised of three-quarters water plus undigested food including carbohydrates, fiber, proteins, and fats from the dog’s digestive system. Also present are a wide range of resident bacteria that are needed for digestion.

If dogs are infected with worms, or other disease-causing microbes, these can be present in their poop. Left on the street, dog poop is washed into waterways, creating a potential health hazard. Once pathogenic microbes from the poop get into waterways, they can find their way into other living things — including humans.

People also don’t like dog poop because of its smell. This is due to the volatile products produced by microbes in the gut that are involved in the digestion process. More than 100 different chemicals that could contribute to the bad smell have been identified.

Because poop smells bad, we avoid dealing with it. Local councils offer plastic bags at parks and other public places to encourage dog owners to collect the poop. Bins, sometimes specifically for dog waste, are often placed nearby so the smelly package can be discarded as soon as possible.

But this is not the best solution, because, ultimately, the dog poop ends up going to landfill, contributing to our ongoing problem of waste accumulation.

Why Dog Poop Can Become a Nutrient

Rather than becoming a pollutant, dog poop can become a nutrient for your garden, by being composted in your backyard.

If you have a garden, you can make your own compost bin by adding the dog poop to grass clippings, plant, or other organic waste, and even sawdust as a source of food for the microbes. The microbes then break down the organic material into humus. During this process, the temperature in the compost mixture rises to 50-60℃. Over time, the heat will kill most canine bacteria, as they are adapted to live at lower temperatures in the dog’s gut.

Compost contains billions of microbes per gram of material, and competition from these (as well as the environmental conditions of the compost that are very different from the dog digestive system) assist in promoting destruction of pathogenic canine microbes, if present.

The compost needs to be turned over weekly to ensure uniform composing and oxygenation. Over days or weeks, the temperature in the compost drops, indicating when the decomposition process is complete.

Then it’s time to use your compost to improve your garden!

A Couple of Dog-Doo Dont’s:

• Don’t include waste from unknown dogs or from dogs that show signs of disease.

• Avoid using it on vegetables for human consumption.

If you live in an apartment and don’t have a garden or access to green waste, you can still compost dog poop and use the product. There are small compost bins commercially available for this purpose. Composted material from these can be used on your outdoor or indoor plants.

And if you don’t have any indoor plants, then you should think about getting some, as they can cut down on ozone in the air and even reduce indoor pollution.
