Anita Spiller, director of ESG for Tru Earth, a maker of concentrated detergent strips packed in a paperboard envelope, parses results from a recent survey assessing consumer awareness of the link between single-use plastics and negative impacts to human health, specifically from microplastics.

Packaging World:

Tru Earth’s survey results indicate that a majority of U.S. adults are aware of the connection between single-use plastics and their negative impact on human health, although only 18% can explain why it occurs. What do you take from these results?

Anita Spiller:

In the first question, we looked at the difference between awareness and understanding. The survey shows that 67% of Americans recognize that plastics have a negative impact on health, but that doesn’t mean they truly understand what that impact is. It’s similar to saying, I know that cancer is bad, but I don’t know what impact it would have on me per se. And that’s the piece we’re trying to get to: From an individual perspective, is there understanding and awareness? Because only one in five can actually explain or articulate why these impacts matter, and we believe that understanding is the catalyst to changing behavior.

Survey 1

Results from a second question show that approximately half of U.S. adults are aware of how plastic pollution leads to health problems, including the breathing (49%) and ingestion (53%) of microplastics, as well as hazardous emissions in drinking water (49%). How does that align with the earlier results?

So question one assesses consumers’ existing knowledge, whereas question two is trying to help those who were surveyed draw the connection to themselves as an individual. So they might have this general knowledge about microplastics, but they haven’t yet made a connection to, “Oh gosh, that’s bad for my health.”

Survey 2

Were you surprised at the number of people who are aware of microplastics?

I think it’s a buzzword; many people are talking about it, and they hear it in the news. And I think that it doesn’t necessarily equate to fully comprehending the impact single-use plastics are having on human health. I was at an event this weekend that kind of brought it home for me. I was speaking to a number of young people, and after I spoke, a teenager came up and said, “I have this polar fleece sweater that I absolutely love, and I’ve been doing all of this reading about the amount of microplastics that are shed from my sweater. What am I going to do about it?”

And I was like, wow, she was maybe 13 years old. She was asking about microplastics. And it wasn’t enough for me to give the standard answers, which are to wash it less, spot clean it as opposed to putting it into a washing machine, or use Tru Earth detergent, because we’re going to shed fewer microplastics. That wasn’t enough for her. She really wanted to understand, “Can I capture my microplastic?” And so we had a great conversation about, yeah, you could put a filter on your laundry machine, and you could capture it, but we don’t yet have a solution for what we’re going to do with what you’re capturing. And so we had this great conversation about maybe you’re the person who’s going to innovate. And then it led to a beautiful conversation about what’s the next sweater she’s going to buy, because maybe she’ll buy a wool sweater.

It was amazing. It’s one of those things where I get the opportunity to go out and speak once in a while, and it just fills my cup because I get so excited, especially talking to young people who really do, I think, have higher level of knowledge and a higher connection to what matters for them. And understanding that this is going to take collective, unified, strategic action and education to better inform consumers and others. It’s that deep understanding we’re going for.

So it’s not some funky lifestyle trend. It’s actually trying to solve the issue. And the eradication of the production of microplastics is going to require a systems change. We’re not just going to be able to recycle our way out of this. We’re not going to be able to just go to a thrift store more often. We have to turn that plastic tap off.

What was Tru Earth’s goal with this study?

Surveys are a way for us to get the pulse on what consumers are aware of and whether they’re understanding the issues related to single-use plastics and what I love calling “short-lived plastics.” I do think many consumers understand single-use as in the case of, “I used this takeout container for less than 30 minutes, and now it’s going to exist on our planet for hundreds of years.” But I think it’s the short-lived plastic, like a household cleaning product container that you might use for a few weeks or a couple of months, that they don’t think of. So we’re trying to educate our consumers on all the different kinds of plastics.

We regularly talk to our customers and our partners about our ecosystem, but the survey is one way for us to get the data and to understand which avenues we need to be entering into in terms of education, because it’s critical, I think, for all of us to provide education around the topic.

The third question measures consumers’ willingness to make changes in the products they use. Fifty-two percent said they’d be willing to change their household products packaged in plastic in favor of plastic-free alternatives, while 59% said they’d be willing to actively try to avoid all single-use/short-lived plastics where possible. If they are aware of the negative health impacts of single-use plastics, why haven’t they made changes already?

The biggest takeaway for me is that change is hard. When it comes to laundry detergent specifically, the vast majority of people use the laundry detergent that was used in their family-of-origin home. It’s mom that’s sending children out into the world—whether that’s off to college or to their first job or into their first apartment—and so they buy what mom bought. And so it’s hard for them to make a change because this is what mom uses.

It’s also an issue of education, and that’s why we prioritize educating young people, mostly between grades four to eight, because they take that education back into the home, and they can make that change in their home environment.
