More than a nuisance

Dog waste is a recognized pollutant that is unsightly, smelly, and potentially contains disease-causing pathogens. The U. S. pet population is now outpacing the human population. According to a recent survey by the American Pet Products Manufacturers Association, 63% of all American households own pets - up from 56% in 1988. 74.8 million dogs are now introducing 10M tons per year into the U.S. ecosystem.

What do you do with it?

Toilets and sanitary sewage treatment have provided modern man with a workable solution to human waste disposal. But there is no effective, broadly-implemented solution to eliminating the problem of dog waste. At this point, dog owners, shelters, kennels, breeders, pet shops, municipalities, and pick-up services are left to their own resources. Currently the most common methods of disposal of this waste are tossing it in the trash, or leaving on the ground. Both have large negative consequences.

Landfills = waste in perpetuity

Half of the dog waste in urban corridors is dumped into garbage bins which are emptied into landfills The trash option usually involves plastic bags which can take centuries to degrade while the waste inside is mummified for posterity. The landfills themselves are a disaster waiting to happen.

The Wisconsin Department of Natural Resources states: "Current landfill designs and practices do not provide for degradation of landfilled organic wastes within a defined and reasonable timeframe. Undegraded organic wastes can potentially cause future environmental or economic impacts if the landfill gas and leachate collection and containment systems (cap and/or liner) fail at some time in the future. Potential economic burdens and environmental risks associated with these undegraded wastes will be largely borne by future generations."

According to the U. S. Geological Survey, "…landfills are designed to minimize contamination of ground water, but modern landfills eventually may leak contaminants into the environment."

Across the country, landfills are topping out, raising rates, and losing favor as a solution for the 230 million tons of solid waste generated in the U. S. annually. Ecologically savvy communities are looking for innovative ways to divert waste from landfills.

Letting nature take its course

Roughly 40% of all dog owners do not "stoop and scoop." Don't kid yourself - dog waste does not gracefully embrace the ecosystem. If left intact, it can take more than a year to break down. Until then it poses a health threat to people and pets. Unlike wild animals that actually help propagate forests with their thinly deposited scat, domesticated dogs leave waste behind in proximity to human activity. The resulting nuisance factors are obvious.

Dog waste can quickly turn any outdoor area into a site unfit for humans. In addition to the mess and smell, the high nitrogen level of raw waste kills grass and other plant materials. If left on concrete, the waste runs off intact into storm sewers and contaminates waterways.

Recent studies indicate that dogs are third or fourth on the list of contributors to bacteria in contaminated waters, increasing the potential for serious diseases, including cholera and dysentery. In addition to threats to humans, bacteria that feed on dog waste deplete oxygen, killing native aquatic life. They are also feed "algae blooms" which block sunlight and suffocate fish.
