The world produces an unlimited quantity of plastic. Global plastic manufacturing elevated from 2 million metric tons in 1950 to 348 million metric tons in 2017. Yet a lot of this plastic is wasted: 86% of the world’s plastic waste in 2016 was both incinerated, despatched to landfill or leaked into nature.
Many international locations use worldwide commerce to handle their plastic waste. The justification for that is that plastic waste will be handled in locations with higher capability for waste therapy. The UK, missing capability itself, exports 60% of its plastic waste overseas. But in a current report, the House of Commons Environment, Food and Rural Affairs Committee – the group of MPs liable for bettering and defending the setting – have referred to as on the federal government to cease the export of UK plastic waste by the top of 2027.
The motion of hazardous waste is managed by a global settlement referred to as the Basel Convention. It requires the consent of the receiving nation, correct labelling of waste, and notification when plastic waste has been handled for waste to be exported legally. The Convention has just lately elevated the vary of plastics that fall inside its remit.
China has lengthy been the world’s main plastic waste importer. But in 2017 its authorities banned plastic waste imports, citing issues over the low high quality of fabric obtained. This has displaced huge portions of plastic waste. The UK now exports most of its plastic waste to Turkey, Indonesia, Vietnam, Malaysia and the Netherlands.
Passing the burden
The import of plastic waste is a precious supply of overseas change for a lot of international locations. But these international locations usually have restricted waste therapy infrastructure.
Uncontrolled imports can subsequently result in the quantity of plastic waste obtained exceeding the capability of a rustic to deal with it. It additionally displaces its capability to deal with its personal home waste. The result’s extra plastic waste than will be safely dealt with and excessive ranges of mismanagement.
Once a rustic has obtained the waste, monitoring of the therapy course of can also be scarce. A Greenpeace investigation in 2021 discovered proof of plastic waste from the UK and Germany dumped illegally throughout 10 websites in southwestern Turkey.
But mismanaged plastic waste is without doubt one of the primary causes of plastic air pollution in nature. One report estimates that 56% (239 million metric tonnes) of worldwide annual plastic waste manufacturing by 2040 will likely be topic to mismanagement.
Exporting plastic waste additionally raises moral questions. It permits exporting nations to forgo their accountability to cope with their very own plastic waste whereas claiming to be managing their waste responsibly.
A extra systemic and accountable approach of coping with plastic waste is to cut back plastic consumption. The Committee’s report recommends measures that concentrate on lowering plastic waste at supply, fairly than bettering the power of waste therapy infrastructure to handle a better capability of waste.

The key suggestion was to speed up the introduction of Extended Producer Responsibility schemes. Extended Producer Responsibility is an method that goals to make firms bear a better proportion of the price of disposing the plastic they use for merchandise put available on the market. These schemes will apply to all firms within the UK who put at the very least 1 tonne of plastic packaging available on the market every year by 2030, encouraging them to cut back their manufacturing of plastic waste. This will be achieved by means of improvements to “design out” plastics or by transitioning to a round financial system the place plastic supplies are reused or totally recycled.
The Committee’s report recommends the institution of a plastic reuse job power, composed of representatives from trade and client teams. The group would coordinate methods together with incentives to undertake enterprise fashions that encourage the reuse of plastic supplies, single-use plastic costs, obligatory reporting on an organization’s plastic footprint, and public campaigns to boost the profile of reuse schemes.
Deposit-return schemes additionally assist and are already in progress within the UK. In 2023, Scotland will launch a nationwide programme the place individuals can pay a 20p deposit after they purchase a drink in a plastic bottle or can, which will likely be repaid when the empty container is returned.
Plastic waste is a worldwide downside
The suggestions made by the Committee are a optimistic step ahead and would place the UK ready of worldwide management on tackling plastic air pollution. But plastic worth chains are transnational and waste is generated at every stage. This reduces the effectiveness of remoted nationwide motion.
National insurance policies usually would not have the attain or affect to sort out the worldwide causes of plastic air pollution. Research that I co-authored discovered that remoted insurance policies together with nationwide bans on plastic merchandise are ineffective in lowering the era of plastic waste. Fragmented nationwide insurance policies also can create loopholes in worldwide coverage that inadvertently reroutes plastic waste in direction of the locations least geared up to cope with it.
But earlier this yr, 173 international locations formally adopted a UN decision to begin negotiations for a worldwide legally binding settlement to finish plastic air pollution by the top of 2024. The World Trade Organisation has additionally launched an initiative to discover how commerce insurance policies can be utilized to cut back plastic air pollution. International cooperation over plastic waste coverage, together with the authorized energy of the Basel Convention, gives hope of a coordinated international response to plastic air pollution that avoids coverage fragmentation.
Environmental teams are essential of the commerce in plastic waste. The Committee’s advice to ban UK plastic waste exports by 2027 is subsequently an formidable and welcome step forwards in tackling plastic air pollution. But with out international motion, remoted nationwide insurance policies is not going to ship change on the dimensions required to finish this controversial commerce.
