Single-use plastics in the age of coronavirus

The coronavirus pandemic has been a blow to efforts in reducing the consumption of single-use plastics. The lockdown saw consumers, warned they may need to self-isolate for 14 days if symptoms developed, stocking up on long-life foods packaged in plastic. Many companies banned reusable products from their stores, forcing people to revert to single-use plastic bags and disposable cups. On top of that, there’s been a surge in PPE usage worldwide. People are buying single-use gloves and masks to protect themselves, alongside copious amounts of hand sanitiser, soaps, and household disinfectants.

Consumer anxiety has been further heightened by plastic lobbyists, who took the opportunity to announce that reusable bags and cups are nowhere near as safe as the single-use plastics their livelihoods depend upon.

The virus survives in droplets coughed, sneezed or spit out and travels through the air until they fall to the ground or hit something in their way. Once it attaches to a surface, unless it’s a surface it can infect, it’s vulnerable to being destroyed. If you can wash something, you can disinfect it from the coronavirus.

Coronavirus particles can hang around for up to twelve days on plastic surfaces, depending on the strain. The good news is that it’s really quite easy to destroy the virus by disinfecting and sanitising surfaces. Basic soap and water is enough to do the trick if you don’t have access to a disinfectant.

Water alone won’t work particularly well. Coronaviruses are surrounded by a hydrophobic envelope layer that prevents water molecules from breaking open the particle and damaging the virus RNA. It’s the addition of soap that’s key. Most household cleaners are fine to sanitise hard surfaces, and fabric can be cleaned in the washing machine with detergent.

With that, let’s break down some of the risks and benefits of single-use plastics compared to their reusable counterparts.

Plastic bags

Businesses that handle food in the UK are required to follow certain safety procedures, ensuring that products are clean and that the chance of infection is as low as possible. This means that there’s not likely to be any contamination of pre-prepared food and drink, or on the outer packaging of most foods. You may still come into contact with the virus if someone who has it (whether or not they realise) has handled something you’re interacting with. This is why it’s important to maintain distance in shops and only touch products you’re intending to buy. 

This goes the same for single-use plastic bags. Nothing makes them inherently more sanitary than anything else in the shop, and unless you yourself are carrying the virus they won’t necessarily be any cleaner than the bags you bring from home. As long as your bags are regularly cleaned (i.e. washing cloth bags and giving plastic ones a quick wipe down with disinfectant) they’re safe to use and you can continue to avoid unnecessary plastic use.

Cups

Again, there are certain standards in the UK that have to be met when you’re being served hot drinks. Your coffee does not have coronavirus floating in it. There’s a risk, just like with supermarket products, that you may touch a surface that’s been contaminated but most shops are carrying out regular sanitation. Staff should be wearing appropriate PPE and everything used to make your drink should have been cleaned before and after. 

Dishwashers are perfectly effective at dealing with virus particles, and scrubbing your cup in the sink with some dish soap will also work if you don’t have access to a dishwasher. If you’re regularly cleaning your reusable cup (and we’d hope you’re washing it between coffees), you should have nothing to worry about.

Masks

The latest announcement from the UK government is that face coverings will be compulsory in shops in England from the 24th of July. Until now, the government has held off advising mask use for the general public but that advice is set to change in light of increasing evidence that masks are effective at limiting the spread of the virus at the population level.

There is a difference between cloth face coverings and masks that qualify as personal protective equipment (PPE). Generally, masks that achieve PPE status are single-use, with re-use only allowed under extremely limited circumstances. Disposable masks absorb moisture after prolonged use, meaning that they won’t protect you any more than a cloth mask will once they’ve been compromised. Masks that meet the N95 standard also need to be fitted properly, and are designed for use in healthcare and surgical settings, where they are changed between patients. The blue surgical masks that many people associate with the term “face mask” are for protecting the wearer from splashes or droplets that may come into contact with the mouth and nose area. They are not as effective at blocking airborne particles that can be breathed.

The majority of people won’t have much need for a mask that meets the standards required for use in hospitals and care environments. Adhering to social distancing measures means a cloth mask should be more than adequate in most situations. They should be washable – and you should aim to clean them after every use.

If you’re looking for the best ways to make a mask, Happy DIY Home has tutorials for several types, including a no-sew version.

Gloves

Nitrile or latex gloves are the other item of PPE that members of the public can be seen wearing regularly. These are definitely only single-use – reusing disposable gloves is extremely inadvisable. They are difficult to clean, as washing them in water means that you probably won’t get them dry enough to ensure that they’re not going to provide a breeding ground for bacteria. Sterilising them in extremely hot temperatures or with alcohol-based cleaning products changes the physical properties of the glove, rendering them weaker and more prone to tearing or breakage.

A box of disposable gloves may appear sterile. They’re not – and once you’ve touched a couple of surfaces with gloves they’re not going to be much cleaner than your hands. Gloves in a medical or scientific setting are often used to prevent cross-contamination and so would be changed frequently. Most people wearing gloves are not changing them anywhere near as often as would be needed to prevent the transmission of the virus, and there have been suggestions that gloves may lull people into a false sense of security, making them less likely to follow sanitation procedures that are just as necessary with gloves as without.

It’s more effective, and far kinder to the environment, to go without the gloves and instead ensure you are continuing to wash your hands regularly.

The use of disposable plastics and single-use PPE during the pandemic cannot be avoided in some cases – hospitals and healthcare providers absolutely need them to limit the spread of the virus. It’s really not necessary, however, for the public to avoid reusable and environmentally-conscious options when they’re for personal use. Most of these can be sanitised fairly easily, and single use plastics outside of a medical setting are often no cleaner or safer than their eco-friendly counterparts.

Make 2020 Your Year for Low-Impact Living

Low -impact living 2020: a reusable bamboo coffee cup on a wooden bench.

We’re in a climate emergency. The Earth is dangerously close to its tipping point in terms of being able to come back from the damage humans are causing to our ecosystems. The devastating bushfires in Australia are merely a taste of what countries may face in the coming decades if we don’t take steps to lessen the damage we are causing to the planet.

The climate emergency is a borderless issue – its effects will not be limited to the countries that don’t take it seriously. Global efforts are necessary to combat this global problem, and change needs to happen at every level. Countries need to be working together, governments need to be putting policies in place for their own countries, businesses need to commit to sustainability, and individuals need to make changes to their lifestyle to lessen their impact on the planet.

We’re starting at the bottom, with a campaign to get as many people as possible trying low-impact living in 2020.

What is low-impact living?

A low-impact lifestyle, or low-impact living, is pretty much what it says on the tin. You try to reduce the impact your lifestyle has on the environment. It’s fundamentally “reduce, reuse, recycle”.

Reduce what you take from the environment and the waste you produce.

Reuse as much as possible

Recycle what you can’t use any more.

Nobody lives a completely impact-free life, and nobody should expect perfection. But your lifestyle choices may have more of an impact on the environment than you realise. You can check your personal environmental footprint here.

Why do I personally need to try low-impact living?

Low-impact living shouldn't cost the Earth - and it might save you money in the long run.
Low-impact living shouldn’t cost the Earth – and it might save you money in the long run.

The UK government has committed to reducing emissions by at least 100% of 1990 levels by 2050, and to limit global temperature rise to as little as possible above 2°C. To do this, they’ve set 5-year carbon budgets that will run until 2032. Currently, we’re in the third budget, which runs from 2018-2022.

We’re doing OK at the moment. We’ve hit both our previous budgets and we’re likely to beat our target in this one. But we’re not going to hit the fourth target if we don’t make some major changes. The government has not put enough firm policies in place to reduce carbon emissions. Many of these policies involve changing the way individuals live their lives to reduce their impact on the environment. Everybody needs to get involved if we’re to have any hope of meeting our emissions targets.

We’re going to take a massive hit to our way of life if we don’t take more action now. The wildfires we’ve seen in recent years are just a fraction of what we can expect. More weather events like extended droughts will reduce the availability of food. Rising sea levels will flood low-lying coastal areas, forcing communities to surge inland. Sure, in the short term areas like the UK may see higher yields of food crops – but we don’t have the capacity to feed the parts of the world that would have been producing food had we not fried the Earth. And that period of productivity won’t last forever.

But you know all this. The question is: are you prepared to do something about it?

So how do I go low-impact?

Low-impact living might be as simple as changing the type of soap you use.
Low-impact living might be as simple as changing the type of soap you use.

It doesn’t have to be much to start with. Cut down on your plastic use, eat those leftovers instead of heading out for a meal, walk or take public transport rather than drive if you can. Nobody lives a truly impact-free lifestyle and it’s better to make small changes where you can than not doing anything at all.

The goal with low-impact living is to reach a circular economy:

Not depleting finite resources.

Recycling products at the end of their life cycle rather than throwing them away.

Extending the lives of those products to reduce the amount of energy needed to process them.

Most of the things that we can do to achieve low-impact living are easy enough, and come with the added bonus of saving you money in the long term. Here are a few ideas to get you started:

  • Buy your produce loose and take a reusable shopping bag with you. Less packaging means less plastic to throw away. You can also choose exactly how much of something to buy if you can get it loose.
  • Switch to bar soap over liquid soap. Bar soaps use far less packaging and waste far less product per use than liquid soaps. They aren’t always as convenient, but they last longer and smell just as good!
  • Ditch the single-use bathroom products. Makeup wipes and cotton pads for skincare products are things you might use every day. You can get reusable cloths and use your hands to apply your skincare and you’ll cut down on waste in a big way. If you’re prepared to take the extra step, reusable menstrual products are widely available and easy to use.
  • Buy your electronics secondhand. Got your eye on a new phone? Check sites like eBay and Gumtree to see if there’s one on there – all too often people buy one new, don’t like it and sell it on at a hefty discount. It’s true you won’t get to pay it off monthly, but you’ll pay less than full price and your contract will be cheaper if it’s SIM-only. Plus, you’ll save one perfectly usable device from ending up in landfill and avoid the extra packaging you’d be dealing with buying it new.
  • Own a reusable cup – and use it. Single-use plastics and paper are everywhere. And while paper cups actually have a lower carbon footprint than ceramic mugs or reusable cups on a per-use basis, they still create waste that goes into landfill or takes energy to recycle. You need to use a reusable plastic or metal cup 20 times before it becomes more environmentally friendly than a paper cup – but we’d guess students will have reached that number of coffees by about Wednesday of every week anyway.
  • Switch to an eco-friendly search engine like Ecosia. We’ve posted before about Ecosia, and we’re going to keep plugging them because of the reforestation work they do. The campaign Royal Holloway on Ecosia has more information in case you need persuading.
  • Take public transport where you can, or walk. Public transport is better than cars, Walking or cycling is better than public transport. Some places may not have the best infrastructure in place for getting around in not-a-car, but if it’s available to you, use it. Oh, and take the train for long-distance domestic travel instead of an internal flight. Please.
Low-impact living: take public transport where you can.

We’ll be posting regularly about how you can change your lifestyle to reduce your impact on the Earth, so keep an eye out. And let us know your favourite ways to go low-impact in the comments below, on Facebook, or Twitter!

Ecosia: Save the Planet While You Search

This article is a guest post written by Rhiannon Morey, founder of Royal Holloway on Ecosia. Download Ecosia using this link to support the Royal Holloway on Ecosia campaign.

In case you haven’t heard of Royal Holloway on Ecosia…

We are a group of five first year students aiming to promote Ecosia – a search engine that plants trees. We want to inspire Royal Holloway, University of London to make environmentally friendly changes on campus, starting with setting Ecosia as the default search engine.

I first heard of Ecosia in 2018 whilst on holiday in Germany and I have been an avid user ever since. The more I read about the company, the more I was impressed at how much good they do on huge scales around the world, as well as offering individual benefits for the user. When I started at University, I knew it was something I wanted to bring to campus. Four other students joined me and Royal Holloway on Ecosia launched on 18th November 2019. The difference we can make could be huge if the 10,000 students and over 1,500 staff at Royal Holloway used Ecosia every day!

We are part of the officially recognised Ecosia on Campus campaign. It originally started with just 3 students at Sussex University but has now spread around the world with campaigners in Spain, France, America and Brazil, just to name a few. At the end of 2019, campaigners managed to finance the planting of over 85,000 trees! This is an incredible figure illustrating how much environmental impact students can have when working together. Here at Royal Holloway, we are so proud to be part of this international community.

What is Ecosia, we hear you ask…

Like Google, Ecosia is a search engine that makes its money through advertisements. But instead of being a for-profit business, Ecosia donates 80% of its surplus income to tree planting projects across the globe. They have planted over 80 million trees so far and we want Royal Holloway to contribute to its goal of 1 billion trees!

The benefits of this search engine reach far beyond the environmental aspect, supporting livelihoods, habitats and restoring landscapes amongst others. For instance, Ecosia’s servers are running from their own solar energy plant meaning that Ecosia is carbon-neutral (something many companies could only dream of achieving). Not only does Ecosia use renewable energy, the planting of trees helps to remove 1 kg of CO2 from the air. Incredibly, this means that Ecosia is an almost unheard-of carbon-negative search engine. On average, trees will each remove 50 kg of CO2 during an expected 15-year lifetime. With a tree planted every second at Ecosia, the search engine could absorb 15% of all global CO2 emissions if it was as big as Google which is enough to offset vehicle emissions worldwide! What a difference that would make to the current climate crisis!

There is also a tree counter on the right side of your browser allowing users to track the number of trees you personally have contributed to.

Ecosia runs tree-planting projects where they're needed most.

As well as using profits to plant trees, the company constantly strive to help their users make environmentally friendly choices in their daily lives. One of the ways they do this is by placing a green leaf icon next to websites that are eco-friendly like those that sell sustainable products.

Last Summer, Ecosia launched their travel service (in partnership with HotelsCombined). Ecosia plants 25 trees each time a holiday is booked! To use this service, just enter “hotel” in the search bar or directly access Ecosia Travel via the “more” button on their search results page.

Ecosia also has an online shop selling t-shirts and hoodies all made with organic cotton. Each one sold plants 20 trees!

Berlin based founder of Ecosia, Christian Kroll has also made a legal commitment to protect the future of the company, ensuring that shares can’t be sold at a profit nor owned by people outside of the company and that no profits can be taken.

Ecosia is also completely financially transparent, publishing monthly financial reports so users can see exactly how and where profits are being spent. Along with this, users can stay updated on tree planting projects in areas such as Burkina Faso, Peru and Madagascar (mainly biodiversity hotspots) through regular video and blog updates so you can see for yourselves the good they achieve. Ecosia also protects your privacy. They don’t sell your data to advertisers, have no 3rd party trackers and anonymize all data within a week. What more could you want from a search engine?

Here are just some of the ways trees benefit our world…

  • The most powerful CO2 absorbers are trees
  • Trees help mitigate climate change
  • Water cycles can be restored by trees
  • Trees stop the spread of deserts
  • Barren land is transformed back into productive forests and farmland by tree planting
  • Trees grow fresh produce
  • Trees help shape landscapes and build up deforested areas
  • The strong roots can stabilize shorelines and mountain sides
  • Trees help restore degraded lands and allow people to flourish off their land instead of moving in search of better living conditions
  • Trees provide us with clean oxygen
  • Local men and women are able to find stable jobs and earn their own income to help stabilize political and economic conditions in developing countries. As a result of this money, parents can afford to send their children to school, buy medicine and build houses
  • Trees provide a habitat for endangered animal species around the world, supporting biodiversity

How Royal Holloway can help…

As a campaign, we will endeavor to spread the word about Ecosia and try to persuade the University to make the switch by setting Ecosia as the default search engine on campus.

While the business is truly remarkable, they can only make a difference because of people like you. The good news is that by just searching the internet, you can actually help the environment from the comfort of your own home for free! Use our campaign’s unique URL to download Ecosia TODAY on your devices here. This URL allows our team to track the number of trees planted by our University and we look forward to seeing the number of trees grow!

Like our Facebook page and follow our Instagram for updates on events and for more information about Ecosia.

Please tell all your friends and family about this initiative – with the help and support of everyone at Royal Holloway, we can make it the default search engine. Show our University that its students care about the future of our planet.

The urgency of the climate crisis is something that cannot be ignored. This is something tangible that we can do to make a difference, as individuals and as a University.

Thank you and Happy Tree Planting!
