China's Hidden Plastic Problem: The 12 Types You Didn't Know About

China is a massive player in the plastic industry, but there's a lot more to the story than just the usual suspects like PE and PP. There are 12 types of non-commodity plastics that don't get as much attention. These plastics are tricky to define and track, making it hard to figure out how much is made, used, and what happens to them at the end of their life. This is a big deal because it means we don't have a clear picture of the full impact of plastics on the environment and society. These non-commodity plastics include things like PET, PU, and a bunch of engineering and thermosetting plastics. In 2022, China churned out around 85 million tonnes of these materials. That's a huge amount, and it's about the same as the more well-known commodity plastics. About a third of these plastics are used to make plastic products, while the rest end up in non-plastic applications like fibers and rubber. PET, for example, is mostly used in short-lived packaging like bottles and containers. On the other hand, plastics like PU, engineering plastics, and thermosetting plastics are used in longer-lasting applications. This means we need smart recycling strategies, especially chemical recycling for PU and thermoset products. These plastics are often found in things like car parts, electronics, and construction materials, which makes recycling them a real challenge. The problem is, these plastics are often overlooked because they don't fit neatly into our usual definitions of what plastics are. This makes it hard to create effective policies to manage them. By taking a closer look at these non-commodity plastics and improving the data we have on them, we can start to address some of these gaps. This will help us make better decisions and reduce plastic pollution more effectively. It's clear that we need to rethink how we define and manage plastics. By focusing on these often-overlooked non-commodity plastics, we can start to fill in the gaps in our knowledge and create more effective strategies for reducing plastic waste. This is a complex issue, but by taking a critical look at the data and challenging our assumptions, we can start to make real progress.
