Today US dogs produce more waste than humans did in 1959

Much of the 11 million tons of dog waste generated in the U.S. each year is trashed and streamed to lined and sealed landfills. The rest is left on the ground as a potential pollutant, particularly in urban areas.

The average dog poops more per day than the average person. Throw in the tons of plastic we use in a foolhardy attempt to sanitize this absurd process.

Add it up and you find that today U.S. dogs generate more solid waste than the U.S. human population in 1959. Can you imagine an advanced country in 1959 not providing a practical sanitary disposal system that works for its 178 million people? We have a hard time wrapping our heads around that one and hope you do, too.

Human waste quantities

On average humans excrete 128 g (.28 lb.) of fresh feces per person per day – Rose, C.; Parker, A.; Jefferson, B.; Cartmell, E. (2015). “The Characterization of Feces and Urine: A Review of the Literature to Inform Advanced Treatment Technology,” 3.1

Dog waste vs. human waste

.28 lbs. human waste per day vs. .75 ave. dog waste per day

2016 U.S. dogs

83 million dogs x .75 lb. waste per day = total 62,250,000 lb. waste per day ÷ 2,000 = 31,215 tons per day
31,215 tons per day x 365 days = 11.4 tons dog waste per year

1959 U.S. humans

177.8 million humans x .28 lb. waste per day = total 49,784,000 lb. per day ÷ 2,000 = 24,900 tons per day
24,900 tons per day x 365 days = 9 million tons per year

 

San Francisco volunteers to compost 32M pounds of dog waste per year

A first-of-its-kind system in San Francisco for composting dog waste is designed to demonstrate the potential to keep 32 million pounds of waste from an estimated 120,000 dogs from entering the landfill each year and move the city closer to its goal of zero waste.

The initiative provides dog owners with compostable bags dispensed where they walk their dogs, a collection bin and a pick-up service, which was unveiled at the Starr King Open Space in San Francisco’s Potrero Hill neighborhood on Sept. 25.

Here’s the scoop.

Metro Vancouver: take pet waste to treatment plants

In the U.S. there are no restrictions on how dog daycares, animal shelters and scooper services dispose of the tons of waste generated by their furry clients. Pet poop takes up the most space in their dumpsters, which are collected by trash trucks and streamed to landfills. Metro Vancouver has a better idea. In that city, large quantities of dog or other animal waste are banned from the garbage.

The city instructs multi-pet operations to either transport waste or make arrangements for transporting waste to their closest transfer station or wastewater treatment plant. Dog waste and cat waste accepted at wastewater treatment plants cannot be mixed with clay litter, sand, rock, grit or any kind of bag, including biodegradable.

Several dog waste removal services have disposal privileges at area plants and will contract with multi-pet operations to transport their waste.
