CompostableLA Founder Monique Figueiredo on Biodegradable Vs. Recycled Poop Bags · Kinship

Gasp! “Compostable” poops bags are bad for the environment? Sustainability expert Dave Coast gets the scoop from CompostableLA founder Monique Figueiredo.

Is there anyone more of a nuisance to society than someone who doesn’t clean up after their dog — leaving their pet’s poop lingering on the sidewalk, awaiting an eventual meeting with some poor dude’s vintage Chuck Taylors? While this act (or lack thereof) is likely deliberate, even good Samaritan dog walkers are capable of waste-related damage — albeit unintentionally. When scooping up your dog’s latest work in a poop bag before tossing it in a nearby can, you may not be ruining any local’s sneaker game, but you are inadvertently harming the environment.

The harsh truth is that most of those bags are made of plastic and will take hundreds of years to decompose, therefore flooding landfills and creating air pollution. Of course, you already knew that, so you bought compostable poop bags when you first brought your pup home. The harsher truth is that even waste solutions promoted as biodegradable or compostable are rarely that. They’re generally derived from bioplastics — a plastic made from biological materials, such as plants and fibers — which take just as long to decompose, creating the same issues.

To make sense of this muddied field and what help is available, we spoke with Monique Figueiredo, founder of CompostableLAopens in a new tab, who offer a compost pick-up service to many LA neighborhoods. Figueiredo really knows her sh*t when comes to compost and pet waste, so let’s get educated.

Yes, this is the norm, because cat litter and pet feces can contain harmful bacteria and parasites. We give our end product, aka “compost,” back to our members to use in their gardens. While it’s technically possible to compost dog fecesopens in a new tab, it would have to be done separately, and for a longer time to kill the pathogens, only to be used afterward in non-food-producing gardens.

Cat litter and feces, in particular, should never be composted because they may contain Toxoplasma gondii, a parasite that can infect humans and animals, which isn’t always killed during the process. As a result, most composting facilities will ask you to dispose of pet feces in the trash.

Yes, that’s correct. From this point forward, just imagine that’s where it will sit for a very, very long time.

Bioplastic refers to plastic that is made or derived from biological materials (plants and fibers), and/or is biodegradable under specific conditions. Marketing claims around bioplastics are often confusing, suggesting to consumers that their “made from plants” packaging will degrade to nothing over a period of time. It’s very important to emphasize that bioplastics are chemically different from the actual plant that they were derived from, and they don’t break down the same way food waste does.

Exactly! If the bag is biodegradable, all that means is that it will decay into different components over a long period of time, such as water, smaller pieces of plastic (aka “microplastics”) and even methane. If the bag is “compostable,” it means that it can be broken down via microbial digestion and leaves no harmful materials behind. The only caveat is that it requires very specific conditions to do so. If it doesn’t have those conditions, it will not break down properly either.

A: “biodegradable” bags will take decades to break apart, often into smaller pieces of plastic, while simultaneously releasing methane.

B: “Compostable” bags ends up in a landfill and don’t have the conditions they need to break down properly, so they don’t break down and will ultimately release methane into the air?

Yes. Since it is composed of organic matter; that is correct.

It absolutely is greenwashing. In fact, I’d like to argue that there are products that are not only more expensive but worse for the environment because they contain “virgin” materials, which have their own carbon footprint to produce, plus release methane in landfills.

That’s why I recommend pet owners use recycled plastic poop bags. They contain materials that were already in the system and bound for the trash since recycled materials eventually must be thrown away. Also, unlike their bioplastic counterparts, they do not release methane.

I use Green Polly, because they are made from 90 percent post-consumer recycled plastic. They are strong, comparable in size to standard poop bags, and widely available online. If you are picking up a lot of pet waste at one time, I like Hippo Sak’s recycled plastic bags made from ocean-bound plastic.

Remember that single-use is single-use. Even if it says it’s “compostable,” know that it most likely will end up in a landfill, so the goal is to use fewer new materials whenever possible.
