The UN’s chief of environmental affairs has issued a stark warning regarding the escalating production and pollution caused by plastic

She asserts that simply relying on plastic recycling is insufficient to address this crisis, urging a comprehensive reevaluation of our plastic consumption patterns.

Inger Andersen, the director of the UN Environment Program, emphasized during an interview at the General Assembly in New York that with plastic production soaring globally and pollution worsening, the status quo cannot be maintained. She underscored the need for a collective reimagining of how we utilize plastic materials.

Two weeks following the release of the initial draft of an impending international treaty on plastic pollution, anticipated to be finalized by the end of 2024, Andersen shared insights into the diverse ambitions of the 175 participating nations.

These ambitions range from advocating for a reduction in raw polymer production to emphasizing reuse and recycling.  Mixed-Plastics Recycling

Andersen’s approach starts with eliminating as many single-use plastics as possible, especially those that serve no necessary purpose, such as items wrapped in plastic that are naturally encased, like oranges or bananas. She also suggested reevaluating the very nature of products, questioning whether they need to be in liquid form and exploring alternatives like powders, compressed forms, or concentrates. For instance, she mentioned her habit of checking the soap aisle in supermarkets for solid alternatives.

Furthermore, Andersen stressed the importance of reducing the overall supply of new raw polymer, an option outlined in the draft treaty text. She pointed out that while recycling efforts are essential, plastic usage continues to rise. Over the past two decades, annual plastic production has more than doubled, reaching 460 million tons, and this figure could triple by 2060 if no significant changes occur. Currently, only nine percent of plastic is recycled, leading to plastic waste contaminating oceans, wildlife, and even human biological systems through microplastic pollution. Mixed-Plastics Recycling

Andersen emphasized that relying solely on recycling will not suffice in addressing this crisis. She expressed that if the inflow of new raw polymer into the economy remains unchecked, the problem of plastic pollution in oceans will persist. She underscored the critical importance of ocean health for humanity’s future.

The future treaty on plastic pollution is expected to complement global initiatives aimed at protecting oceans, including the recent historic treaty covering the high seas, which was signed by around 70 nations. Andersen hailed this development as a vital step in safeguarding a crucial portion of our shared heritage—the oceans.

New Chemical Process Offers Hope for Mixed-Plastics Recycling

A molecular additive allows different kinds of plastic to be recycled together

Soda bottles, sour cream containers and disposable cutlery—these plastics (and many others) typically arrive at recycling plants mixed together in the same bin. But because they are made of different molecular building blocks, called monomers, they must be sorted into different streams before they can be melted to make new products.

“Until about a year ago, everybody thought the only thing you could do is take a plastic, break it back down to a monomer and then re-form it,” says Sanat Kumar, a chemical engineer at Columbia University. “Now we’ve come up with a different way of doing it.” His team has developed a process that allows different kinds of plastic to be recycled together. Their findings, reported recently in Nature, could give new life to many items that end up in landfills. Mixed-Plastics Recycling

A disturbingly small portion of our plastic waste is recycled, and production of new plastic—made from fossil fuels—continues to increase. The worsening situation has prompted scientists to seek new solutions to old recycling problems, including the difficulty of recycling mixed plastics. But they have faced a fundamental chemical hurdle: when different plastics are melted together, their various monomers tend to separate from one another like oil and water.

Salt Water-Degradable Plastics To Help Oceans

“Researchers at the University of Queensland are developing a groundbreaking solution to combat marine pollution: saltwater-degradable plastics. Dr. Ruirui Qiao, affiliated with UQ’s Australian Institute for Bioengineering and Nanotechnology, is spearheading the development of an affordable, biodegradable plastic that disintegrates in seawater, aiming to mitigate the proliferation of persistent plastic waste in our oceans.

According to Dr. Qiao, our oceans are increasingly contaminated by long-lasting plastic items such as containers, bags, and microplastics, posing a significant threat to marine ecosystems and the countless seabirds and mammals that rely on them. While awareness of this issue has grown in recent years, the scale of plastic waste entering the water necessitates innovative solutions. Dr. Qiao believes that plastic degradation technologies hold promise as part of the solution. Mixed-Plastics Recycling

Collaborating with fellow researchers, including Professor Tom Davis and Professors Xuan Pang and Xuesi Chen from the Changchun Institute of Applied Chemistry, Dr. Qiao’s team is utilizing cutting-edge 3D-printing techniques developed by her research group at AIBN and polymeric materials from the Chinese Academy of Sciences to create a range of customizable, high-value seawater-degradable plastics.

This collaborative effort has received $125,000 in funding from the Queensland-Chinese Academy of Sciences Collaborative Science Fund to expedite the project’s progress over the next two years. One of the techniques they are employing, known as ring-opening polymerization, enables precise control over the mechanical properties and form of the plastics while imbuing them with a low-toxic polyester “backbone.” As a result, these plastics can break down into a molecular state when exposed to marine environments.

The ultimate goal is to commercialize a new line of products in both Australia and China within five years, effectively replacing conventional plastics and capitalizing on a burgeoning biodegradable market projected to exceed $9.5 billion by that time. Dr. Qiao emphasizes that seawater-degradable polymer plastics will play a vital role in reducing plastic debris in the world’s oceans, enhancing the well-being of ecosystems and the quality of life for communities globally.
