UN: Plastic pollution could be cut by 80% with recycling and reusing

Plastic pollution could be reduced by 80% by 2040 if countries and companies make deep policy and market shifts, the UN Environment Programme (UNEP) said.

To do this, there needs to be more reusing, recycling and more reorienting and diversifying of plastic products, the authors said.

This would include governments promoting refillable bottles, bulk dispensers, deposit-return-schemes and packaging take-back schemes – which could reduce 30% of plastic waste.

An additional 20% could be reduced if recycling became a more stable and profitable industry, while removing fossil fuel subsidies and forcing packaging designers to enhance products' recycling capabilities would mean the amount of recyclable plastics would increase from 21% to 50%.

Using alternatives such as paper or compostable materials instead of plastic for wrappers, sachets and takeaway items could also save a further 17% in plastic pollution, UNEP said.

All this would still leave 100 million tons of single-use and short-lived plastic waste, which UNEP said could be dealt with by setting and implementing design and safety standards for its disposal, such as making manufacturers responsible for products shedding microplastics.

UNEP's executive director Inger Andersen said: "The way we produce, use and dispose of plastics is polluting ecosystems, creating risks for human health and destabilizing the climate.

"This UNEP report lays out a roadmap to dramatically reduce these risks through adopting a circular approach that keeps plastics out of ecosystems, out of our bodies and in the economy.

"If we follow this roadmap, including in negotiations on the plastic pollution deal, we can deliver major economic, social and environmental wins."

The report, titled Turning off the Tap: How the world can end plastic pollution and create a circular economy, comes before a second round of negotiations in Paris on a global treaty to tackle plastic pollution.

The authors of the report said shifting to a more circular economy would result in savings of $1.27 trillion while a further $3.25 trillion would be saved from improved health, climate, air pollution, marine ecosystems and litigation-related costs.

It would also create a net increase of 700,000 jobs by 2040, mostly in low-income countries.

UNEP said the investment costs are "significant but below the spending without this systemic change" – $65 billion as opposed to $113 billion without the change.

Much of this could be raised by using investments that would have been earmarked for more plastic production, or by introducing a levy on virgin plastic products.

Failing to introduce these policies in time and delaying by five years could lead to an increase of 80 million tons of plastic pollution by 2040, UNEP said.

The UK government announced in January that it was introducing a deposit-return scheme in 2025 where plastic bottles will come with an extra cost that is redeemable once recycled.

It is estimated that five million tons of plastic is used every year in the UK, half of which comes from packaging.

Plastic has been found in almost every corner of the world, including Antarctica, while earlier this year scientists recorded for the first time a disease caused by plastic in birds – named plasticosis – which inflames the digestive tract.
