    Plastic is the workhorse material of the modern economy (经济). Lightweight and durable, it’s been used to make a vast number of products since its introduction over 100 years ago.

However, a study carried out by the World Economic Forum, the Ellen MacArthur Foundation and McKinsey Company showed the status of the breakdown in the global plastic system. A full 32% of the 78 million tons of plastic packaging produced annually is left to flow into our oceans.

The Ocean Cleanup, a start-up founded in 2013, is the brainchild of Boyan Slat, who came up with the idea for the company when he was just 17 years old. Since then, it’s received more than $2 million in funding(基金). The company plans to use a large array (列阵) that will be fixed to the bottom of the Pacific Ocean. This will have arms that spread out over 100 km, getting all of the plastic garbage pushed into its nets. This is then collected by a 10,000-metre-cube container that will be emptied monthly.

Most recently, the Ocean Cleanup launched a team of explorers aboard a specially refitted C-130 Hercules aircraft heavily loaded with specialized sensor equipment. It discovered that the problem was worse than expected with an abundance of plastics measuring up to 1.5 m across and at a higher density than previously thought. The organization will continue to pilot the array and will start cleaning the pile before the end of the decade.

Once the plastic is out, what should we do with it? The foundation (基金会) hopes that the plastic from the ocean will have a commercial value which can help to fund the project. Ocean plastic is not easy to use, it’s mixed by nature consisting of everything from intact PET bottles to micro plastics. However, some of the world's biggest companies also see the chance to market oceans plastic products.

Transforming today’s plastics economy from its present form (take-make-waste) to a zero waste circular economy (take-make-take-make) is a difficult challenge. However, with cooperative action from producers, recyclers, governments and consumers alike and continuing innovation (革新) it can be done.
