Don’t waste your time recycling plastic

Plastic Problems, and One Woman’s Trashy Journey to Zero Waste.”

The time has come for us to stop “recycling” plastic. Plastic as a 
material is not recyclable, and the very best thing we can do to 
celebrate Earth Day this year is to acknowledge that fact.

This seems counterintuitive, I know. We’ve been told for decades that 
the answer to the plastic-waste crisis is more, better recycling: If 
only we sorted better! If only we had better access to recycling 
technologies! If only we washed and dried our plastics more adequately! 
This is all a smokescreen, designed to distract us from the truth that 
plastic recycling — if by “recycling” we mean converting a used material 
into a new material of similar value and function — is a myth.

Unlike paper, glass and metal, plastic is not easily, efficiently turned 
into new products. What passes for “recycling” plastic is costly, 
energy-intensive and toxic. On top of all that, the process requires the 
addition of a shocking amount of new virgin plastic— around 70 percent — 
to hold the newly formed plastic item together. As a result, only about 
5 percent of plastic gets “recycled” (or, more accurately, “downcycled” 
into a product of inferior quality). Compare that with a 68 percent 
recycling rate for paper and cardboard.

Considering that, as a society, we’ve been actively trying to get better 
at plastic recycling since the 1970s, 5 percent represents a colossal, 
unequivocal failure. It tells us that plastic “recycling” is, at heart, 
an empty, performative gesture.

Many environmentalists will protest this assertion. They might correctly 
point out that plastics labeled with the resin identification code of 1 
or 2 (the number inside the “chasing arrows” triangle on many plastics) 
have a higher measure of recycling success: about 30 percent. Shouldn’t 
we support recycling at least this plastic?

For a long time, I thought so.

But this brings us to another myth: that plastic is harmless to human 
health. What many people do not know is that plastic is made from two 
ingredients: fossil fuels and toxic chemicals. When we say toxic 
chemicals, we are talking about some very bad actors: heavy metals, per- 
and polyfluoroalkyl substances (PFAS), flame retardants and persistent 
organic pollutants. Tens of thousands of proprietary chemical formulas 
are involved in the production of plastic, most of which have never been 
tested for their effects on human health, although many are known to be 
endocrine disruptors, fertility inhibitors and carcinogens.

What this means is that even if we were to get better at recycling 
plastic, we shouldn’t want to. When you grind up, melt and re-form a 
bunch of plastic (with the addition of lots of new virgin plastic to 
bind it together), all those thousands of toxic plastic chemicals 
combine to make a Frankenstein material that has what scientists call 
“non-intentionally added substances” in it. Which is to say that 
chemicals that are not supposed to be there start showing up. A study 
last year concluded that recycled plastics contain “an unknown number of 
chemical compounds at unknown concentrations.” In 2021, a Canadian study 
concluded that plastic is “not suitable for processing into food grade 
PCR,” referring to post-consumer resin.

The upshot? You do not want your food wrapped in recycled, 
mystery-ingredient plastic. But what if we use recycled plastic only for 
nonfood items such as picnic benches? Then we have yet another deeply 
troubling aspect of plastic to deal with: microplastics. We’ve been 
hearing more and more about these lately, because scientists are finding 
them everywhere they look — in the environment and in the human body.

The chemical composition of all plastic — whatever the type — is a 
synthetic polymer that doesn’t break down or go away, ever. Instead, it 
breaks up into smaller and smaller pieces until it turns into 
microplastics or even nanoplastics. These tiny particles are still 
plastic, still toxic, but now so small that we are eating and breathing 
them all the time. Microplastics have been discovered in human lungs, 
bloodstream and breastmilk, as well as in the placenta of unborn babies. 
Scientists have found microplastics in sperm, testes and the brain.

The effect of all this plastic in our bodies is still being revealed, 
but we know it is substantial. A recent study concluded that the disease 
burden from plastic exposure includes preterm birth, obesity, heart 
disease and cancer, and the health-care cost was $249 billion in 2018 
alone. The human body has become the trash can of our plastics-addicted 
culture.

Trying to recycle plastic makes the microplastics problem even worse. A 
study of just one plastics recycling facility discovered that it might 
be washing 3 million pounds of microplastics into its wastewater every 
year — all of which ends up being deposited in our city water systems or 
dumped into the environment.

At this very moment, we all have microplastics coursing through our 
bodies. This is not the fault of not enough recycling. This is the fault 
of too much plastic. So I say: Let’s treat plastic like the toxic waste 
it is and send it where it can hurt people the least.

Right now, that place is the landfill.

Then we need to get to work on the real solution: making a whole lot 
less of it.
