Plastic waste is a global problem. Now a chemist has developed a new strategy for breaking down the most common plastic so it can be not just recycled, but upcycled into desirable goods.
As much as 53 million tonnes of plastic waste could spill into the world's rivers, lakes and oceans by 2030 — even if countries meet their commitments.
New Zealand's potential to expand its domestic recycling sector is enormous. It could create jobs and divert millions of tonnes of waste from landfills, as long as there are clear, measurable targets.
A media study of public criticism of plastic reveals that stigmatisation may result in limited bans, it leaves the vast majority of plastic production and pollution unexplored.
Even recycled plastics still end up in landfill with our current system.
To manage plastic wastes, nations first need to know what they have and where it's coming from. A case study from Trinidad and Tobago shows how this approach can help identify solutions.
2019 was a big year for dire warnings about the state of the planet, but crises can spur solutions.
Waste-to-energy incineration has been raised as a solution to the global plastic waste problem, but the technology adds pollution and greenhouse gas emissions and encourages more waste production.
Consumers are much more likely to recycle their waste after viewing messages showing the products it might turn into.
Plastic washed ashore from the ocean is hard to recycle. What else can we do with it?
A nanotube innovation using waste plastic could help solve one of the world's energy problems.
As well as polluting our seas, plastics are warming the planet too. Urgent changes are needed to eliminate plastic's contribution to climate breakdown.
Asian countries have become a dumping ground for the plastic waste from wealthy countries.
Since China stopped accepting Australia's recyclable plastic, the majority of exported plastic waste is now going to developing nations in South East Asia.
There are lots of issues with recycling – but it's still an important part of society's efforts to live more sustainably.
Cleaning up plastic pollution in the ocean is good – and long overdue. But where will the waste go? Recycling isn't always an option. Bacteria and enzymes could process it, raising new questions.
