The plastic we throw away doesn’t just disappear, it comes back smaller

As Illinois moves to confront microplastics, Ontario is reorganizing the machinery that handles the plastic we throw away

MANITOULIN—There is something unsettling about plastic. It is everywhere, and yet almost nowhere we can see. A bottle disappears into a blue box. A food wrapper disappears into a garbage can. A synthetic shirt goes through the washing machine. A cigarette filter falls into a ditch. Out of sight, the problem seems to have gone somewhere else.

But plastic does not disappear into the ether. It breaks down and fragments, becoming smaller and smaller until it can move through water, soil, air and living bodies in pieces too small for the human eye to see. Now, governments are beginning to grapple with what happens after the plastic has become almost invisible.

Illinois is among them.

But the story coming out of Illinois is not quite that the state has declared microplastics a “poison,” despite how the development has been characterized in some reporting. Rather, Illinois has been steadily building a regulatory framework around a contaminant its own environmental agency describes as an emerging environmental concern with potential human and ecological health effects.

The distinction is significant because the science around microplastics is still evolving and because the question facing communities around the Great Lakes is becoming increasingly difficult to avoid: What do we do with a material we have built an economy around when we discover that its smallest pieces may be among the hardest things to control?

Illinois’ environmental agency defines microplastics as plastic particles between one nanometre and five millimetres. They can come from larger plastic products breaking down, synthetic clothing fibres, tire wear, industrial pellets and a host of other sources. 

The Illinois EPA notes that microplastics have been found throughout their ecosystems and can enter food chains. It also acknowledges emerging evidence of inflammation, oxidative stress and effects on organs including the liver, kidneys and lungs, while stressing that research into long-term human health effects remains ongoing.

The responsible story is not that every microscopic plastic particle is a proven human poison. It isn’t. The responsible story is that we have created an environmental contaminant so pervasive that researchers are still trying to determine precisely what prolonged exposure means. And the particles are not waiting for the science to catch up.

A Great Lakes problem

For Manitoulin, this is not some distant American concern. The Great Lakes are one interconnected body of freshwater, and what enters the system upstream does not respect political boundaries.

The Manitoulin Expositor has been reporting on microplastics since 2012, being the first Canadian media outlet to report on the initial Great Lakes microplastics finding, under then-editor Alicia McCutcheon. In 2025, the paper reported that more than 22 million pounds of plastic pollution enter the Great Lakes annually, according to research from the Rochester Institute of Technology. 

In 2022, Manitoulin Streams’ Seija Deschenes warned that plastic garbage accumulating along Island roads eventually breaks down, allowing the chemicals associated with those plastics to enter water. At the time, she estimated that Canadians were throwing away about three million tonnes of plastic waste annually, with only about nine percent being recycled.

The same story pointed to synthetic clothing as another source. Fibres from polyester, nylon and acrylic garments can shed during washing and enter wastewater systems.

The problem is therefore much larger than the blue box. In January, The Expositor returned to the subject following a Manitoulin Nature Club presentation by the Lake Huron Coastal Centre.

The message was blunt: Lake Huron receives an estimated 600 metric tonnes of plastic every year, roughly the equivalent of 40 dump trucks. And once that plastic enters the environment, it becomes somebody else’s problem only in the political sense. Biologically, it remains everybody’s problem.

The plastic economy has a waste problem

That brings us back to Ontario’s blue boxes.

Ontario completed its transition to a producer-responsibility model on January 1, 2026. Municipalities are no longer responsible for operating or funding the provincial Blue Box program. Instead, producers are financially and operationally responsible for the packaging, paper products and packaging-like materials they place into the marketplace. Circular Materials operates the collection system on behalf of producers.

The transition represents a major logistical change. Hundreds of municipal systems have effectively been consolidated into a producer-run framework.

Waste companies are adjusting to new contracts and new collection territories. Circular Materials has contracted with private operators to provide collection services across Ontario, creating what York University circular-economy researcher Calvin Lakhan has described as an opportunity for greater logistical and operational optimization.

There is an obvious efficiency argument. Instead of hundreds of municipalities independently managing collection, a smaller number of large operators can coordinate routes, processing and material flows. That may save money and may reduce duplication making the recycling system more predictable, but another question lurks beneath the blue box: What happens when recycling itself is being asked to solve a problem that begins long before the recycling truck arrives?

Ontario’s Blue Box regulation establishes recovery requirements for materials including rigid and flexible plastics. For 2026 through 2029, the regulation sets a 50 percent recovery requirement for rigid plastics and 25 percent for flexible plastics, rising to 60 and 40 percent respectively from 2030 onward.

Those are recovery targets not disappearance targets. A plastic package can be successfully collected, sorted and recycled while the larger environmental system continues producing millions of tonnes of new plastic.

Recycling cannot recycle its way out of infinite production.

Illinois is asking what happens after the drain

Illinois’ current legislative debate illustrates the importance of the distinction. House Bill 2955, amended in 2026, was given the title PFAS and Microplastics Wastewater Citizen Protection Act.

The proposed legislation recognizes that microplastics and PFAS enter wastewater treatment systems through consumer products, industrial products and solid-waste streams, including landfill leachate and also recognizes something that should sound familiar to anyone who has ever tried to make an old municipal system do a new job:

Wastewater treatment plants were not designed specifically to remove these contaminants.

If governments eventually require them to do so, the infrastructure could face significant capital and operational costs. The bill proposes creating a committee to monitor developments in microplastics regulation and treatment technology, investigate mitigation options and develop an action plan while also explicitly contemplates identifying funding sources that could include manufacturers and industrial users.

The question then shifts from how to clean up the mess to who should pay for cleaning it up, the question producer responsibility was supposed to confront.

The invisible bill comes due

Ontario’s new Blue Box system is built around the idea that producers should bear responsibility for their products once consumers are finished with them. In principle this makes sense, but microplastics are exposing the limits to this logic. A plastic producer may be responsible for packaging recovery, a municipality may be relieved of collection costs, a private contractor may optimize a route and a processor may recover material.

But when microscopic particles from plastics, synthetic fibres, tires and degraded products end up in a lake, river, sediment or wastewater sludge, the chain of responsibility becomes much harder to follow. The Illinois EPA acknowledges that microplastics can be generated by everything from degraded packaging to tire wear and synthetic textiles.

There is a tendency in environmental reporting to treat every new study as the moment a problem suddenly appeared but microplastics do not fit that narrative.

They have been accumulating for decades and The Expositor’s own archive demonstrates that.

The progression of the paper’s reporting from 2012 to 2026 is telling. Plastic particles were discovered, then how widespread they were and now governments are finally beginning to ask what they are supposed to do about them. 

Canada has already used the word “toxic”

There is another wrinkle in this story, and it comes home to Canada. In 2020, the federal government added plastic manufactured items to Schedule 1 of the Canadian Environmental Protection Act’s List of Toxic Substances. That does not mean every piece of plastic is a poison in the conventional sense of the word.

The federal designation is a legal environmental-management classification based on the potential for plastic pollution to cause environmental harm. The government specifically cited evidence that macroplastics cause ecological harm and that microplastic pollution may also pose ecological risks, while acknowledging that more research was required.

In other words, Canada has already crossed a regulatory threshold that recognizes plastic pollution as a problem worthy of toxic-substance management and the science continues. And yet so does the plastic. 

The Great Lakes cannot afford another “out of sight” solution

For Manitoulin, the implications are intimate. The Island is surrounded by Lake Huron which provides drinking water, food sources, tourism opportunities. Water is not only economy, but in particular for First Nations communities, water is culture that carries responsibilities that predate the arrival of the blue box by millennia. 

The IJC has warned that monitoring remains fragmented. Without consistent methods for measuring microplastics in water, sediment and aquatic life, communities are left trying to understand a contaminant that can be everywhere while being difficult to quantify.

The uncertainty should neither be mistaken for safety nor should concern be conflated with certainty. The honesty is much more uncomfortable. While we know that pervasive microplastics enter the Great Lakes where wildlife ingests them and that humans are exposed through food, water and air with particles carrying and interacting with other contaminants, we are still learning what chronic exposure might mean for human health. Now the question as to why both governments, producers and consumers alike have yet to apply the precautionary principle while the science catches up remains. 

A contaminant small enough to pass unnoticed into the systems that sustain us does not become less consequential simply because we cannot see it. Our lakes have been telling us this for years.

We have mostly answered with better garbage collection while perhaps the next answer has to be something more difficult: making less garbage in the first place.
