The world’s resources are finite. The more we personally use, the less there is for others. We should reuse, repair and recycle what we do use. Plastic is conventionally made from oil but can be made from recycled plastic which has both a smaller carbon footprint and allows virgin oil to be left in the ground together with its potential carbon emissions.
Recycling plastics is a good thing.
Whilst all plastic can potentially be recycled, with some forms of plastic the process is deemed too expensive. Plastics that can easily and cheaply be recycled are typically the ones that can go in your kerb side recycling bin or in recycling points at super markets etc. Items made of several different plastics can be difficult to recycle but more and more business are making this possible. Costa Coffee collects coffee cups for recycling (typically made of paper with a thin plastic lining). Superdrug collects blister packs from pills etc for recycling.
32% of all plastic in the UK was recycled in 2020: including 50% of plastic packaging and 77% of plastic drinks bottles. Plastic that is not recycled ends up in landfill sites or incinerators, or as pollution in rivers and the sea. There is scope for more and better recycling. Equally there is scope for reducing the amount of plastic that is in circulation. Do we need all that plastic packing? Do bananas need to come in plastic bags? Do we need drink coffee from throw away cups? Why aren’t sandwiches wrapped in paper?
Good Plastic Recycling Practice
Before throwing plastic in the land waste bin, check whether it could be recycled. If necessary contact the manufacturer. If enough people keeping asking, they may even swop to a more readily recycled plastic.
Check the type of plastic you are recycling. Is it a recyclable plastic that can go in your kerb side bin or do you need to take it to an alternative recycling point? The ‘wrong’ sort of plastic can contaminate the recycling process.
Make sure the plastic is clean: rinse to remove traces of food, detergent etc. Dirty plastic can contaminate the recycling process.
Stack plastic trays together to minimise the amount the of space they take up – this stops your recycling bin from overflowing and reduces the need for larger sized recycling trucks. Similarly flatten plastic bottles. Both these practices will prevent loose items of plastic being falling or being blown out of your bin.
Organic September, Movember, Veganuary, No-Mow May and now, Plastic-free July. Most months have a focus on changing habits to create a better future. Plastic-free July advocates remove all plastic from our daily lives – from the tooth brush in the bathroom, the plastic fruit packet from the supermarket to the once ubiquitous plastic carrier bag. The tax on plastic bags – now at 10p per bag – has significantly reduced their use: 212 billion plastic bags were sold by retailers in 2016-17, and only 496m in 2021-22. It is likely that it has not been so much the cost of the bags that has led to their decreasing use, but the change in expectation and habit that the original introduction of the tax engendered. Cotton reusable bag in all shapes and sizes are now widely available (often as freebies) and to carry one is the social norm.
Why is it desirable to get rid of plastic?
Plastic is made from oil, one of the main sources of carbon dioxide emissions causing global warming. Producing one tonne of plastic generates up to 2.5 tonnes of carbon dioxide (Material Economics, 2018). As the world’s use of plastic rises, so does its consumption of oil. In 2019 we the world produced 460 million tonnes of plastic, up from 313 million tonnes in 2010 and is likely to,triple by 2060https://ourworldindata.org/grapher/global-plastics-production
One way of reducing the carbon footprint of plastic is to reuse existing plastics. Some items such as PET bottles, widely used for soft drink, can be recycled repeatedly. This is closed loop recycling meaning that the plastic is recycled to create an identical replacement item. (Open loop recycling recycles plastics but produces a lower grade plastic for which an alternative use must be found). To be effective closed loop recycling depends upon consumers ensuring that they do put their plastics – washed and clean – in the correct recycling bin and upon manufactures using exclusively that recycled plastic. In the UK only 30% of plastics are recycled!
Plastic rubbish pollutes our streets, rivers, woodlands, and oceans. It doesn’t naturally decay and instead remains intact for 100s of years. Plastic that does tear and break down into smaller and smaller pieces still doesn’t decay. Micro plastic particle have been found polluting glaciers and icecaps, and polluting oceans where it is being ingested by sea birds and fish. Micro plastics are also found in the air we breathe and in the water we drink. Micro plastics can be found lodged in our lungs and in our blood.
Current estimates suggest that 8 million tonnes of plastic end up in the oceans every year adding to the 150 million tonnes already there. Projects are now being set up to remove plastic waste from the oceans. In 2020 a 48 day expedition by the Ocean Voyage Institute removed 103 tons from the Great Pacific Garage Patch. Other projects are being developed to process such waste into reusable plastic based materials: Patagonia uses recycled marine polyester in its clothes, Parley Ocean Plastics supplies material for Adidas shoes and Waterhaul in Cornwall uses marine plastic to produce sunglasses.
This is till only ‘a drop in the ocean’! The better solution is not to use the plastic in the first place. Hence Plastic Free July! Why not start now?
Plastic Free July’s own web site is a good starting point as is that of Friends of the Earth and City to Sea. You will also find plenty of web sites looking to sell you plastic-free products – and possible more than you need! Our own personal experience of shifting to a – largely – plastic free lifestyle began by collecting all the plastic that came into the house over a two week period. Then for each item we looked to see if there was a plastic free alternative for the product itself or of buying the same product without the plastic packaging, or whether we actually could manage without the item altogether. Over the next few months we looked for tried different ways of shopping – going to farmers’ markets, refill stores, buying in bulk, taking our own washable box to the butchers or coffee jar to the roasters – until we found the best fit for our lifestyle. Even today we are still making adjustments as new options become available. We have also written to suppliers asking them to use plastic free packaging. Whilst I don’t often have anything positive to say about Amazon, they have developed a simple straightforward cardboard packet for their deliveries!
Our own shift towards plastic-free and zero waste living has reduced both the amount that goes into our recycling bins as well as what goes into our dustbin. The latter is currently needs emptying twice a year.
