PARIS - Humanity uses and abuses hundreds of millions of tonnes of plastic a year because “it’s so cheap”, despite the huge cost of the pollution it creates, the head of the UN Environment Programme told AFP.

Today, virgin raw polymer is cheaper than recycled polymer. So here’s the question: What will allow us move from that linear “we take it, we make it, we waste it” reality to a circular approach? Right now, it’s so inexpensive you can just throw plastic away. But the cost to the environment and human health is huge, and it is not taxed anywhere.

Less than 10% of plastic is recycled today – is that a credible solution?

We can’t recycle our way out of this mess. But recycling is one of the many keys that we will need to make this work. Today, we simply throw plastic away because it has no value.

When I was a little girl growing up in Denmark with very limited pocket money, my brothers and I collected plastic bottles every Saturday because we could get two krone. It wasn’t much, but it made it worthwhile. Now imagine the day that this stuff has value – we would think about and treat that garbage very differently!

Awareness is step one. Which is not to say the burden falls entirely on consumers - at the end of the day, it’s business and governments that have to take that responsibility.

But every consumer has a choice. Let’s say we have a party. Do we need single-use cups and plastic bags? If that bag I use to carry home five tomatoes is a heavy polymer, it will sit in a landfill for hundreds of years, maybe a thousand. Why are supermarket bananas in a plastic...
