Dog waste to provide electricity for Waterloo homes

Dog waste to provide electricity for Waterloo homes

Waterloo, Ont.’s new dog poop power pilot project has been the talk of the country this week, with its promise of unleashing pet waste as a renewable energy resource.

Dubbed “poop power” by Mayor Dave Jaworsky, the pilot project starts with three pet waste containers placed in three Waterloo parks, including Bechtel Park, which has a leash-free dog zone.

Spring is the time to start recycling pet poo

With 83 million dogs and 96 million cats in the U.S. alone, pet waste is a serious problem, polluting land and waterways and contributing upwards of 10 million tons of material to landfills every year. For years we’ve been told not to recycle dog and cat waste. But the fact is that, with due diligence, there are many ways to take your pet to near zero waste by diverting his or her waste from landfills.

Find ways to significantly reduce household waste by recycling your pet’s waste via The Pet Poo Guide: How to Compost and Recycle Pet Waste, a must-read for pet owners concerned about the environmental impact of their best friend. This book offers step-by-step instructions for eight ways to recycle and practical advice on choosing which one is the best solution for you.

The Pet Poo Guide: How to Compost and Recycle Pet Waste is now available online and at area book stores.   Are you ready to nudge your pets much, much closer to net zero waste?  Order your copy of the Guide today at Amazon, New Society Publishers, Lybrary.com ebooks or your favorite book store.

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.

What to do with dog poo

Brooklyn dog park now upcycling poo

“Dog waste in and of itself doesn’t have any value…so we decided to create value out of it by upcycling it to fertilizer,” Leslie Wright of the New York State Parks Department said.

A pilot program at Williamsburg East River State Park is testing the feasibility of on-site dog waste composting using scoopers and cedar bins. See the CBSNY post.

Progress on Colorado In-vessel dog waste tumbler

EnviroWagg is customizing a 40-ft. in-vessel tumbler to begin composting dog waste in an enclosed unit. We recently added a new auger and entry chute. An ALLU screening bucket recently arrived on site. This new equipment will break up compostable bags used at the dog parks and screen out any debris left in public disposal bins designated for dog waste. Opening the bags will enable air, moisture and helpful aerobic microbes to process our source material into a safe and productive soil amendment. By the end of 2016 we expect to have finished compost for evaluation. Composting keeps dog waste out of sealed landfills, reduces the volume by 50% and results in a nutrient-rich garden soil.

Composting also reduces methane emissions. Landfill methane is produced because organic materials sealed in a landfill undergo anaerobic decomposition. Basically, this means that because municipal solid waste that is buried in a landfill does not receive oxygen, it will be degraded by microbes that produce methane. A compost pile, on the other hand, undergoes aerobic decomposition. Because it is exposed to oxygen and degraded by a different type of living organisms, composting material produces CO2 (carbon dioxide) instead of methane.
