China trials AI-enabled sorting machines to keep plastic in circular economy

Unilever has joined forces with the Alibaba Group to launch a large-scale closed-loop plastic recycling system in China.

The joint initiative – called Waste-Free World – is part of Unilever’s drive to tackle the root cause of plastic waste and think differently about packaging.

Unilever has set a goal to halve its use of virgin plastic, cut plastic packaging by more than 100,000 tonnes and accelerate its use of recycled plastic by 2025.

The initiative is part of that drive and an active response to the Shanghai government’s plan to create a plastic packaging management system that can be used country-wide to promote a more circular economy.

“Alibaba is supporting Unilever to make it easier for Chinese consumers to embrace responsible consumption across our multiple cross-platforms, including Alipay, Tmall, and Tmall Supermarket by creating a closed-loop scenario for plastic recycling that starts with its purchase, to usage to recycle and repurchase,” says Vice President of the Alibaba Group, Jet Jing.

Recycling machines

Alibaba Group’s VP Jet Jing and Unilever’s North Asia EVP Rohit Jawa are jointly spearheading a closed-loop recycling initiative that sees AI-enabled machines pre-sort plastic into various grades to speed it back into the circular economy

The launch of Waste-Free World saw 20 recycling machines installed as part of a pilot programme in offices and community spaces in two of China’s largest cities, Shanghai and Hangzhou.

Each machine is equipped with state-of-the-art AI technology which automatically identifies different kinds of plastic bottle.

All that customers need to do is to use Alipay – Alibaba’s e-wallet service – to scan the QR code displayed on the screen of the machine and then deposit the bottle into the recycling bin.

Using AI technology, it automatically identifies the plastic the bottle is made of, sorts it and stores it, so that it can be collected and returned to recycling centres and fast-tracked for reuse rather than degraded.

Alongside doing their bit to improve recycling rates, consumers earn Unilever coupons and green energy points on the Alipay ‘Ant Forest’ for each bottle they deposit in the Waste-Free World machines.

Green energy points are awarded to consumers for low-carbon activities. Consumers collect them and then put them to use planting trees or protecting conservation land. Since Alipay Ant Forest’s launch in 2016, it has helped plant more than 200 million trees in partnership with NGOs in arid areas of China.

Keeping plastic in the loop

For businesses, Waste-Free World’s AI-enabled recycling equipment, logistics and plastic processing make it possible to create a circular economy for plastic waste.

Waste-Free World’s ability to pre-sort plastic packaging into its various grades “enhances the quality of recycled plastic bottles and means the reuse of plastic materials will be more effective and could better contribute to a circular economy,” adds Unilever North Asia’s Supply Chain Vice President, Jennifer Han.

“Plastic has its place, but it should not cause environmental pollution,” acknowledges Rohit Jawa, Unilever’s Executive Vice President of North Asia. “By 2025, we will make an absolute reduction of 100,000 tonnes in plastic use and promote the use of recyclable plastic, so that we can halve the amount of virgin plastic we use in packaging and help collect and process more plastic packaging than we sell.

“We believe Waste-Free World, jointly launched with Alibaba Group, will become the ‘green engine’ of the circular economy for plastic packaging in China,” he says.
