Plastic pollution to weigh 1.3 billion tonnes by 2040

Now is the time to act or else we will be cumulating 1.3 billion tonnes of plastic both on land and in the ocean by 2040, according to the report is published in the journal Science. Dr Costas Velis from the University of Leeds has worked on the research, He said in the statement, “This is the first comprehensive assessment of what the picture could be in 20 years’ time,” Dr Velis explained. “It’s difficult to picture an amount that large, but if you could imagine laying out all that plastic across a flat surface, it would cover the area of the UK 1.5 times.

“It’s complex [to calculate] becayse plastic is everywhere and, in every part of the world, it’s different in terms of how it’s used and dealt with.”

To calculate the numbers, reaseachers keeps an account of the production, use and disposal of plastic around the world. After analysis, team predicted the forecast future plastic pollution. What they called a “business as usual” scenario – based on the current trend of increasing plastic production and no significant change in the amount of reuse and recycling – produced the 1.3 billion tonne estimate.

Waste pickers often work in unsafe conditions

Now by adjusting, researchers were able to project how much different interventions and even the numbers little chnaged keeping in mind their model to increase recycling, reduce production and replace plastic with other available materials.

Winnie Lau from the US-based Pew Charitable Trusts, which funded the research, told BBC News that it was vital to put in place every possible solution. “If we do that,” she said, “we can reduce the amount of plastic that goes into the ocean – by 2040 – by 80%.”

Below are some of the mandatory steps suggested by researchers,

  • The world need to come up and reduce plastic production and consumption.
    Plastic substitute needs to find out whether it is paper and compostable materials.
    Designing products and packaging for recycling.
  • Rate collection rates should be increased in middle/low-income countries and supporting the “informal collection” sector.
  • Plastic waste exports should be reduced.

But, Dr Velis explained, the model showed there would be 710 million extra tonnes of plastic waste in the environment in the next two decades. “They have to just get rid of all their rubbish, so they have no choice but to burn or dump it,” said Dr Velis. And despite playing a major role in reducing global plastic waste, the roughly 11 million waste pickers – people who collect and sell reusable materials in low-income countries – often lack basic employment rights and safe working conditions. Dr Velis said: “Waste pickers are the unsung heroes of recycling – without whom the mass of plastic entering the aquatic environment would be considerably greater.” He added that policies to support them and make their work safer were a vital part of solving this problem.

Dr Ian Kane, from the University of Manchester, who was recently part of a team that calculated the amount of micro-plastic in the seabed, described the picture the researchers had painted as “horrifying”. “The authors are clear that there are large uncertainties in the data and analysis but regardless of the exact figures, the increasing rate of plastic production to meet increasing global demand has pretty dire consequences for the environment,” he told BBC News.

Prof Jamie Woodward, also from the University of Manchester, pointed out the irony in this scenario being laid out during the pandemic.

“Plastic has kept many frontline workers safe through this,” he said. “But PPE waste over the next decade could be horrendous.

“There are parallels with the climate change problem in that business as usual will be disastrous. We need to radically change our behaviour.”
