How Can We Reduce Plastic Pollution in the Ocean?

Experts estimate that about 8 million tonnes of plastic enter our oceans every year. These numbers are overwhelming and as changemakers, it's hard to imagine how we can reduce plastic pollution in the ocean. But sustainability begins at home.

The plastics collected in our water bodies are there because we put them there. Tackling the global problem of pollution will require a concerted effort from households, communities, businesses, and governments. However, we must identify and address our daily contribution to this problem.

The first step? Finding out how plastics go from our homes, workspaces, and factories into the ocean.

Where Does The Plastic In Our Oceans Come From?

Approximately 80% of the litter in the seas comes from the land. Industrial processes and factories are responsible for a proportion of plastic pollution. Poorly managed industrial and commercial practices are partly to blame.

But individuals and households also play a role in creating this problem. It is important to realise that almost all of us will contribute to this issue in some way. Individuals and households contribute to plastic pollution through:

Littering

One of the direct ways that plastic ends up in our waterways and oceans is through littering. Visitors leave plastic bottles and other picnic items on beaches or the wind blows these items to the rivers or shores. However, while littering is a problem, many people with an interest in green living and our environment will know to take their litter home. It is the less well known, and more hidden causes of plastic pollution that are the main problem.

Non-recycled plastic household waste

Many plastics in our homes, especially single-use plastics, are not recyclable. Even that which is recyclable, we often don’t– sometimes due to contamination but often also for economic reasons. Often, recycling businesses simply do not find it profitable to recycle lower-grade plastics. That too can result in more plastic ending up in landfills.

Contamination is also a problem with recycling. Even if you sort your refuse properly, your household plastics can still end up in a landfill. You might have washed out your plastic containers and put them in the correct bin, but that doesn’t mean that everyone else will too. If someone else doesn’t wash their plastics out properly, then it can result in everything in that bin going to the landfill rather than the recycling plant.

Plastic on route to landfills or at landfill sites can easily fly off the trucks, ending up in the streets. The plastics are carried by wind and rain to our waterways, and much of it ultimately finds its way to the sea.

Plastic down the drain

Another way in which lots of plastic makes it from our homes into the oceans is through our drains. Microbeads in cosmetic products are one major source of plastic pollution. These are too small for the wastewater plants to filter out, and may end up in water that flows eventually back to the ocean.

People also flush plastic items such as wet wipes, cotton bud sticks, or sanitary products, which can also make their way into the wider environment. Many people are unaware that certain products they are using contain plastic. They are oblivious to the potential for these items to make their way from their homes, down the drain, and eventually, into aquatic and marine environments.

Another common source of plastic pollution which many people are unaware of is fibres from synthetic clothing. When we wash synthetic clothing in washing machines, plastic fibres will travel down the drain. Outdoor gear, leggings, fleeces, and jumpers made from acrylic and polyester, polyamide, spandex, and nylon can shed up to 700,000 microfibres with each wash1.

Driving cars

Plastic items often erode as we use them and tiny plastic pieces will become detached and enter the wider environment. These microplastics (plastics less than 5mm in length) form another source of plastic pollution. One example of this, which has a significant impact, is driving cars and other vehicles. Tyres (due to friction on roads) create a huge amount of plastic dust2.

What Individuals Can Do To Reduce Plastic Pollution

Of course, plastic comes not just from individual households but also commercial and industrial sources. Businesses and governments also have important roles to play in reducing the plastic that ends up in our oceans. Waste coming from production facilities also accounts for a large proportion of the plastic waste that ends up in the marine environment.

However, as the consumers who buy and use these products, we can incite change in these areas. To put a stop to plastic pollution, we should take some serious measures.

Make your voice count

Lobbying companies that continue to produce non-recyclable plastics, or which are responsible for releasing plastic waste into the environment is crucial. We all have voices, and we should use them as drivers for sustainable change.

But perhaps one of the most important ways to make your opinion matter is to put your money where your mouth is. We can help tackle plastic pollution in the ocean by refusing to buy items we know to harm. We should refuse all single-use plastics whenever we can. And avoid buying plastic items at all when there is a better, greener alternative available.

Of course, we’re stronger together and plastic waste is bigger than any one of us. Consider how you might play a role in helping your local community go plastic free or be inspired and take action to help your local schools go plastic free.

Reduce the plastic packaging you bring into your home

One major source of plastic pollution is plastic food packaging and the packaging of other items we buy. To reduce the packaging we bring into our homes, we can buy less, and buy better. We should:

  • Grow our food to reduce our reliance on packaged, store-bought food.
  • Take reusable containers to wholefood or plastic-free stores to avoid packaging whenever possible. And take reusable bottles, cups, straws, etc. with us when out and about.
  • Choose fresh, buy local, seasonal, organic ingredients rather than packaged junk food.
  • Buy staples in bulk, and ideally from those who offer them plastic-free.
  • Make shopping lists and stick to them, to avoid overconsumption.
  • Learn skills and take a DIY approach, to reduce the amount we need to buy in general.
  • Make do and mend, to reduce our overall consumption. Reuse all items we own for as long as possible.
  • Choose items packaged with cardboard, or home compostable plastics, rather than non-recyclable ones.

Find alternatives to plastic products

In addition to reducing consumption in general and avoiding plastic packaging, we can also help tackle ocean plastic by finding alternatives to many plastic products.

For example, we can:

  • Switch plastic kitchen items for natural wooden/ bamboo/ stainless steel/ silicone ones. And use beeswax wraps (amazon) in place of plastic wrap.
  • Choose wooden/bamboo toothbrushes (amazon), hairbrushes, cleaning brushes, etc..
  • Avoid synthetic fabrics for clothing, soft furnishings, etc., and opt for natural, sustainable textiles instead wherever possible.
  • Select reusable wipes (amazon) rather than plastic wet wipes etc..
  • Ladies - use a reusable cup (amazon) or washable pads rather than disposable sanitary products.
  • Take a look at our guide full of plastic free gifts
  • Or read up a bit more on how to go plastic free in the bathroom

Of course, these are just a few examples. There are plastic-free alternatives for most of the common products we use.

Flush and wash more wisely

Of course, to keep plastic waste out of our oceans, we all need to think more carefully about what we flush down our drains. Be careful not to accidentally flush anything containing plastic down your drains.

We also need to think carefully about when and how we wash synthetic clothes. Even when you are careful to choose sustainable clothing, it is unlikely that you will be able to avoid synthetic clothing entirely.

Wash on a low temperature, and in bulk. Consider washing synthetic fabrics in a bag to catch microfibres. Or add a filter.

Recycle plastic where possible

Of course, no matter how careful we are, we will likely still have plastic to dispose of. This is where recycling comes in. We must be careful to wash and sort well, and make sure we always recycle whatever we can, both at home and then through kerbside/ municipal recycling schemes.

Drive less

Plastic pollution caused by the friction of car tyres on roads is yet another reason, when trying to live in a more sustainable and eco-friendly way, to drive as little as possible. Walk or cycle rather than taking a car whenever you can.

Get involved with a beach clean

Finally, if you want to go that extra mile to help tackle plastic pollution in the ocean you should consider getting involved with a beach clean. While beach cleans cannot tackle the root causes of plastic pollution, or do anything about microplastics, they can help keep wildlife safe and reduce the problem at least a little in your local area.

Conclusion

Plastic pollution and its environmental impacts, specifically on our oceans, is a massive problem. It is not one that we can solve overnight. But by taking a series of small steps as individuals, we can help move things in the right direction and make sure we are part of the solution, rather than part of the problem. These steps in the right direction will support marine conservation and greatly improve the success of other eco-conscious agendas.

Please leave nothing but your footprints
