A report from BNP Paribas Asset Management takes a look at plastic production and waste, and their impact on the world. It highlights annual plastic production regionally from 1980 to date, and forecasts to 2060, based on OECD data.
It also shows that, for the US, very little is recycled, varying by plastic type from 17 percent of PET and 9 percent of HDPE, to less than 1 percent of PVC.
Plastic has been used commercially for almost 120 years and at scale since the early 1950s. About half goes to landfill and a significant amount is “irresponsibly discarded” and leaked into the environment.
At least 8 million tonnes of plastic ends up in ocean waters each year, and unless plastic consumption and behaviour improves markedly, there will be more plastic than fish in the ocean by the end of the century.
Some statistics about the size of the problem include: 1,500 plastic bottles are thrown away every second and over five trillion pieces of plastic reside in oceans.
Plastic pollution causes substantial harm, through air pollution from incineration, microplastics in sea spray and dust in cities.
Plastics enter fresh and marine ecosystems via stormwater runoff, sewer overflows, litter and other routes. They might be in their original form or become microplastics (<5mm) and nanoplastics (<100nm), and can be ingested by marine life, or suffocate and entangle marine animals.
The impact on soil health is also being increasingly understood, and recent research shows that agricultural soils face higher amounts microplastics than oceans, causing problems with soil aggregation, water holding capacity, microbial activity and toxicity.
Its impact on wildlife is broad, including affecting natural habitats, through animals ingesting plastic, inadequate absorption of nutrients for plants, entanglement and injury, genetic mutations and possible effects on reproduction.
Issues affecting human health include endocrine disruption and insulin resistance, reproductive health, cancer, weaker immunity and lung irritation.
Plastics’ impact on climate change is also being recognized. Incinerated plastic reportedly generated almost 6 million CO2e in 2015 in the US alone and is forecast to grow to 49 million per year by the end of the decade. Landfill generates emissions, although less than incineration. Plastic production adds to global warming. In the US, it creates 232 million metric tons of greenhouse gases each year, and this will exceed emissions from coal-fired generation plants in the country by 2030.
BNP Paribas focuses attention almost solely on recycling as a solution to the problem, in investing in more recycling infrastructure whilst acknowledging constraints from feedstock security and economic viability. It mentions alternative plastics and bioplastics but does not mention reuse and refill.
