What are the problems with plastic?
Is plastic simply a litter problem?
“Plastic is a useful everyday item but has grown to become a global problem. Every year the world produces over 460 million tonnes of plastic, 90% of which pollutes almost all areas of our planet, it can be found at the bottom of the ocean, and on our tallest mountains. This pollution can cause harm to habitats and wildlife, impact livelihoods of people around the globe, and carries growing risks to human health. At the current rate, global plastic pollution could triple by 2040 unless we act now” – a quote from WWF. (1)
Could the answer be ‘more recycling’?
Yet last week an article in the Guardian reported that “in the past two years 21 plastic recycling and processing factories across the UK have shut down due to the scale of exports, the cheap price of virgin plastic and an influx of cheap plastic from Asia, according to data gathered by industry insiders.” (2) The UK now exports 600,000 tonnes of used plastic – making it the third largest in the world. Rather than being recycled within the UK, this plastic ends up in countries with neither the infrastructure nor the legal safety constraints to ensure that it is recycled without injuring either the environment or the local populace. The plastic is typically either burnt or allowed to build up in huge waste heaps where it invariably finds its way into rivers and oceans. Much of the UK’s plastic waste is exported to Turkey where, the Guardian reported two people are crushed, ripped, or burned to death in this work every month.
A combination of legislation to end the export plastics waste and taxes to discourage the use of virgin instead of recycled plastic is clearly needed. Rather than letting them close, recycling facilities should be seems as essential parts of the UK’s infrastructure: “If we were to stop exporting plastic waste, and we were to meet our increased recycling target of a 65% recycling rate for municipal waste by 2035, we would need to build 40 new factories across the UK – 20 of them would be sorting facilities and 20 would be processing facilities turning the material back into products,” said an industry source.
Or could the answer be ‘make less plastic’?
Earlier this year, an international gathering sought to agree a global plastics treaty. Work on this treaty began back in 2022 when growing scientific evidence highlighted the risks posed to humans (and other living organisms) by the toxic chemicals that can leach out of plastic as it breaks down. The ambition was not merely to ensure higher levels of recycling, but to to curb in absolute terms the amount of plastic produced globally each year. Plastic production had risen from 2 million tonnes in 1950 to 475 tonnes in 2022. However the treaty was successfully opposed by the large oil-producing nations and members of trade associations representing plastic producers. (3)
What if plastic pollution is a health problem too?
This week there was another newspaper article this time reporting on the spread of plastic into our bodies. “Microplastics have been found almost everywhere: in blood, placentas, lungs – even the human brain. One study estimated our cerebral organs alone may contain 5g of the stuff, or roughly a teaspoon.” (4)
What are micro plastics and where do they come from?
Microplastics are fragments of plastic that is between 1 nanometer and 5 millimetres wide. They come from two main sources:-
- plastics specifically manufactured as microbeads which are added to face ashes, shower bells and other personal care products – they make the liquid both smooth and sufficiently thick that it does run off like water. Think of the difference say between an antiseptic hand spray and an antiseptic hand-gel. These are known as primary microplastics.
- Plastic particles that derive from the disintegration of larger plastic items – eg plastic film and wrapping, takeaway containers, synthetic clothes , care tyres, paints and plastic turf etc.. These plastic particles may be shed as drinking from plastic bottles and take away cups (more plastic is shed when heat is present such as with hot drinks or microwaved food), from wearing and washing clothes, from friction between roads and tyres etc. These are known as secondary microplastics. (5)
Both types of microplastic can pass into water systems, can be present in the air we breathe, and can pass into the food chain and so into the food we eat. Microplastics are to be found all over the world – from the hops of mountains to the depths of the oceans and everywhere in between.
Nanoplastics are even smaller – less than 1,000 nanometers in diameter, or 100 times smaller than the diameter of a human hair. They are small enough to slip through the walls of the cells in our bodies and can be found in our blood, lungs, brains, bones, the placenta and breast milk. (6)
Do these pieces of plastic harmful?
We don’t yet know whether having such buts of plastic in our bodies is good for us (unlikely), neutral or harmful. Nor do we know whether there is a limit below which they are not harmful but above which they might be. It is possible that they may aggravate complaints such as asthma, dementia, cardiovascular disease, cancers etc. (7) The issue is further complicated as plastics contain toxins such as bisphenols (BPA), alkyphenols, and phthalates and dioxins etc, which are also thus passing into our bodies.
It is not just human bodies that maybe adversely affected. Micro and nanoplastics are already known to be adversely impacting the health wild life – eg damaging the gut biomes of seabirds, increasing the number of pathogens present and reducing antibiotic resistance. (8)
Should we panic?
No. We don’t yet know enough to know how dangerous, or not, micro and nanoplastics are. We don’t know whether or not our bodies have a way of eliminating such particles from our bodies. And realistically there is no way we can avoid ingesting these particles given their presence in very part of the environment.
In many instances using plastics can be lifesaving with benefits outweighing the – as yet unclear – disadvantages. For example the use of plastic syringes to give vaccines, plastic pipes to provide clean drinking water, plastic bags for collecting blood donations, waterproofing coats that keep us warm and dry.
But we could cut back on our use of plastic
We can reduce our exposure to plastic particles by reducing the amount of unnecessary plastic we have around us and by adjusting how we use those plastics. For example we might use a reusable water bottle and a reusable cup when out and about (and often cafes give discounts when you bring your own take away cup). You might use glass or metal dishes for storing food and wax wraps or foil instead of cling film. You might use wooden spoons and chopping boards rather than plastic one; metal colanders and metal washing up bowls etc. Equally you might avoid body care products with microbeads and use solid or liquid alternatives. You could try a milk delivery service and get milk in glass bottles rather than plastic cartons. And following that line of thought, you may have a local refill store that allows you to buy various food ingredients and household items without the need for lots of plastic packaging.
There are plenty of guides on line about switching to a plastic free life. eg https://friendsoftheearth.uk/plastics/living-without-plastic and some of my earlier blogs have explored this topic – https://greentau.org/tag/plastic-free/ and https://greentau.org/2022/01/27/eco-tips-zero-waste/
However we should remember that not everyone can afford the plastic alternatives – a metal drinks bottle can cost more that a plastic one. A sliced loaf in a plastic bag will be cheaper than it paper wrapped alternative.
What about changing the system?
If we are going to be fair for everyone and everything – wildlife, ecosystems, future generations, then the whole system needs to be changed.
Nations need to agree on a workable plastics treaty that will cut the amount of plastic produced. The plastics industry needs to develop alternative safe and sustainable substitutes. Governments need to implement a combination of legislation, taxation and investment to ensure that the changes needed do actually happen.
We can advocate for change by supporting groups like Friends of the Earth and Greenpeace, and we can raise awareness about the issue by talking with others – particularly if they are intrigued about the efforts we are making to reduce our use of plastic!
