14 types of plastic that end up in the oceans
Do you know which are the most common types of plastic in our oceans, seas and rivers? From PVC to nylon, there are more than a dozen types of plastic polluting our planet. And we can do something about this problem.
Smells fishy? Not really.There will be more plastic than fish in the sea by 2050.
The warning came in 2016 from the Ellen McArthur foundation, during a meeting of the World Economic Forum.
Five years later, this is still a very worrying concern, despite many efforts to reduce single-use plastic consumption. In 2020, there were still 269 thousand tonnes of plastic floating in our seas and oceans. The infamous Great Pacific Garbage Patch (located between Hawaii and California) is over 79 thousand tonnes, and spans over 1.6 million square kilometres – approximately the same land area as Iran.
But, even though we refer to plastic as a single item, not all plastics are the same. Some take months to decompose, others might take millennia.
Types of plastic that end up in the ocean every day
Nylon, polycarbonates, polyester, polyethylene, polypropylene, polystyrene, polyurethane, PVC, PVDC, acrylic, teflon, silicone, microplastics, biodegradable plastics. Fourteen types of plastic that make up basic, everyday objects – in its vast majority, single-use or with a limited lifespan.
By being discarded incorrectly, these plastics end up in the ocean. Get to know some examples of objects where you can find different types of plastics. By the way, notice how long they take to decompose.
It takes up to 24 months to decompose and can be found in single-use items (cutlery, plates, cups, take away containers).
It takes 20 to 30 years to decompose and can be found in bottle caps, straws, yoghurt cups and car bumpers.
It takes 30 to 40 years to decompose and can be found in toothbrushes, textile fibres and fish rods.
It takes 20 to 100 years to decompose and can be found in kitchenware, contact lenses and baby bottle teats.
It takes 20 to 200 years to decompose and can be found in fibres, textiles or costume wigs.
It takes 100 years to decompose and can be found in eyeglass lenses, CDs and traffic lights.
It takes 200 years to decompose and can be found in musical instruments, golf clubs and helmets.
It takes more than 450 years to decompose and can be found in detergent bottles, shampoo bottles, outdoor furniture, shower curtains, take away containers, shopping bags, single-use bottles, food wrappers and microwave containers.
It takes 100 to 400 years to decompose and can be found in sponges, thermal insulation, paint and polish.
It takes centuries to decompose and can be found in non-stick coating for pans and pots.
It takes 100 to 1000 years to decompose and can be found in cosmetics, body scrubs and toothpaste.
It takes 500 to 1 million years to decompose and can be found in filling, food packaging, disposable cutlery and plates or cassettes.
It takes millennia to decompose and can be found in cling film.
It takes millennia to decompose and can be found in pipes, insulation, electric cables and shower curtains.
Plastic pollution is not disappearing
Although plastic was accidentally discovered more than a century ago, this material has only become extremely popular in the 1970s. Most of all the plastic ever produced still exists to this day. This is because plastic can take between a dozen to a million years to decompose.
Top 10 plastic items found in beaches
A study carried out by the Earthwatch Institute in 2019 reveals the ten items most commonly found in beaches and rivers in Europe.
Each of these objects can be composed of various types of plastics. Nappies, sanitary towels or cigarette butts can contain up to a dozen different plastics.
Some types of plastic are essential
There’s no denying plastic is regarded as the environment’s number one enemy. However, we must admit plastic and its applications are completely essential nowadays – namely in medicine or science.
We refer both to plastic that is used in high technology, such as PEEK (polyether-ether-ketone), used in a variety of medical implants or even to recreate skulls in neurosurgery, and to more common types of plastic, like polyethylene, which has important applications in spacecraft.
At the same time, the discovery of plastic has brought more effective ways to protect and preserve food, extend shelf life or even reduce the carbon emissions associated with product distribution.
The problem does not lie in plastic itself, but rather in how we throw it away, how we process it, and in the world’s obsession with disposable and single-use plastic.
So how can we look at the problem of single-use plastic? Reduce, Reuse, Recycle, to which we add two more actions – Rethink and Refuse – are always good principles. But there is more. Get inspired by some zero waste tips.
