Plastic 101: Microplastics and Pollution

Plastic has become a constant element in our lives, with billions of plastic items being created and briefly used daily. Our reliance on plastic has started the course of mass pollution, leading to an array of planetary issues; but the path we are currently on isn’t irreversible. Small, simple changes in our lifestyle can make leaps toward righting the ship, cleaning our oceans, and saving our planet.

With an estimated 11 million metric tons of plastic ending up in our oceans annually, it’s important to know the “what, why, and how” of plastics so we can help each other lessen the impact we make. In this blog, we’ll discuss how plastic is made, the problem with microplastics, and tips for those who want to use less plastic, along with casting a spotlight on plastic-free brands with excellent products to make going zero-waste easier than ever.

How is Plastic Made?

To make plastic, scientists must take base materials, such as crude oil, and transform them with additives, heat, manipulation, and time into a workable polymer. Though the main component of most of these plastics is crude oil, other materials, such as salt, cellulose, natural gas, and coal are also sometimes used.1

The base ingredients are refined during the plastic-making process into ethane and propane, which are heated in a process known as “cracking” until they transform into the monomers ethylene and propylene. As monomers, ethylene and propylene can then be converted into subsequent polymers via a catalyst.2

Transforming ethylene and propylene into polymers can release toxic emissions into the air and may include potentially dangerous chemical compounds like benzene, ethylene oxide, ethylbenzene, and nickel.3 

Two primary plastics come out of the plastic-making process: thermoplastics, which can be melted, cooled, and molded until they harden, and thermosets, which are not meltable once they have been cooled. Examples of thermosets are epoxy, polyurethane, silicone, and phenolic, while common examples of thermoplastics include acrylic, polyester, polypropylene, polystyrene, nylon, and Teflon.4

Despite popular belief, not all plastics are recyclable. The bulk of plastic recycling is downcycling, meaning plastic degrades with each turn through the recycling process. During this process, though, most thermoplastics break down into microplastics, which can cause an abundance of planetary and health issues.

The Problem With Microplastics

Microplastics, as the name implies, are tiny plastic particles. Officially, they are defined as plastics less than 0.2 inches in diameter, which is smaller than a standard pearl. There are two categories of microplastics known as primary and secondary.

Primary microplastics are tiny particles designed for commercial use, such as microfibers shed from clothing and other textiles. Secondary microplastics are particles that result from the breakdown of larger plastic items like water bottles. This breakdown is caused by exposure to environmental factors like the sun’s radiation and ocean waves.6

The problem with microplastics is that they don’t readily break down into harmless molecules. In fact, microplastics have been detected in marine organisms and our drinking water; standard water treatment facilities cannot remove all traces of microplastics. To further complicate matters, microplastics in the ocean can bind with other harmful chemicals before being ingested by marine organisms.7, 8

Many countries are taking action to reduce microplastics in the environment. A 2017 United Nations resolution discussed microplastics and the need for regulations to reduce this hazard.9 Additionally, going into 2022, the California Ocean Protection Council approved the first comprehensive microplastics strategy in the nation, which identifies early actions and research priorities to reduce microplastic pollution in California’s marine environment.

Plastic Stats and Facts

Undoubtedly, plastics have helped make a number of commodities more affordable, adding vitality to many economies, but the world’s plastic appreciation has turned into a reliance that’s damaging our planet. Here are a few interesting plastic stats and facts to take note of:

  • Nearly 380 million metric tons of plastic waste are produced yearly, which is equivalent to the weight of the human population.
  • Plastic waste is growing at an annual rate of 9%.
  • The US is the world’s top generator of plastic waste.
  • Around 70,000 microplastics are consumed by an average person each year.
  • One million marine animals die due to plastic pollution every year.
  • 75% of all plastic produced has become waste.
  • It takes around 500 to 1,000 years for plastics to decompose.
  • 73% of all litter on beaches worldwide is plastic.
  • About 91% of plastic is not recycled.10

Tips to Help You Use Less Plastic in Your Everyday Life

When we read about the scale of plastic waste in our landfills and oceans, it’s tempting to feel overwhelmed and question whether anything we can personally do would make a difference. However, the truth is that even the smallest changes of habit, accumulated over time, add up to a massive difference. Here are our top six tips for living with less plastic:

  • Try using a reusable produce bag, such as these from Purifyou, as a single plastic bag can take nearly 1,000 years to degrade. 
  • Try to avoid using plastic straws and instead purchase reusable stainless steel or bamboo ones. You can also try compostable straws like the EQUO Grass Straws.
  • Grab your own reusable water bottle, considering that plastic bottles are one of the most common sources of plastic pollution, and are frequently found on beach cleans globally. The Tree Tribe Stainless Steel Water Bottle, for example, is insulated, indestructible, and eco-friendly.
  • Composting is a great way to reduce your waste overall. When you throw away less food, you’ll use fewer plastic garbage bags and storage dishes. Check out this beginner’s guide to composting for tips, tricks, and an easy how-to.
  • You can reduce plastic waste by eliminating plastic bottles of body wash each month. Instead, try switching to soap bars wrapped in paper or cardboard, like these from ECO Amenities, for an easy zero-waste swap. 
  • Disposable plastic razors are not typically recyclable and therefore sit in landfills without ever completely decomposing. The good news is that there are plastic-free options, such as these from Preserve POPi.  

Plastic-Free Brands to Take Note Of

We all face slightly different obstacles when it comes to going zero-waste. Maybe you find it hard to kick the habit of getting your caffeine fix in a takeaway coffee cup? Or perhaps you tend to end up with excess food that finds its way into the trash? These plastic-free brands provide sustainable solutions to help you succeed on your zero-waste journey:

KeepCup

When siblings Abigail and Jamie Forsyth started a café business in Melbourne in 1998, disposable cups were being introduced into the public landscape; but as their business grew, so did their concerns about the volume of packaging being consumed, particularly disposable cups as they were lined with polyethylene and non-recyclable.

The first KeepCups were sold to in 2009 at an independent design market. People recognized KeepCup as the solution to single-use packaging and the volume of waste entering the environment. KeepCups are now used in more than 75 countries around the world and have been named a B-Corp company.

Single-Use Items Need to Go

The convenience of single-use items comes with a massive environmental cost. Unknowingly, your day is probably filled with single-use items that will eventually fill landfills and the ocean. The disposable coffee cups you grab in the morning from your local shop are made with hard-to-recycle materials such as styrofoam, polyethylene, or polypropylene. And the plastic straws? They’re just as dreadful for the environment.

We are producing over 380 tons of plastic every year, and it’s estimated that 50% of that is for single-use purposes.1 However, other materials besides plastic, such as paper, cardboard, styrofoam, and more, are just as bad. It’s time to become more aware of these materials and the single-use items we use regularly. That way, we will help to create a more circular economy for a far more sustainable future.

The Truth Behind Single-Use Plastic Items

Around 40% of single-use plastics are consumed and then discarded.2 Additionally, between 5 and 13 million tons of plastic is estimated to end up in the ocean every year. Single-use plastics need hundreds of years to break down in landfills. Disposable plastic items, such as plastic straws, coffee stirrers, food packaging, bags, and water bottles, never break down completely.3 Instead, they degrade and become microplastics. Plastic has an abundance of negative effects on the environment:

Wildlife Is Suffering

Every year, animals are killed by plastic. Approximately 700 species, even some that are endangered, have been affected by the material.4 Also, more than 100 aquatic species have been found with microplastics inside them, which can lead to pierced organs or digestive tract issues that can potentially lead to death.

Many seabirds, turtles, fish, and marine mammals are found with plastic bags or fishing gear in their stomachs. Currently, marine litter is 60% to 80% plastic, leaving these animals to constantly be ingesting toxic seawater that is full of chemicals from plastic decomposition.5

Our Oceans Are Full of Trash

The oceans are filled with trash, especially single-use plastic items. Our throw-away lifestyle is negatively affecting almost all areas of our ecosystem, especially the ocean.

Every year, 8 million tons of plastic enter the ocean, which is equivalent to one truckload dumped into the ocean every minute of the day. Currently, unless it’s burned, almost every piece of plastic that’s ever been created still exists today. When these plastics enter the ocean, their effects can be felt for centuries.6

The Pacific Trash Vortex, which is in the North Pacific Ocean, holds an exceptionally high concentration of single-use plastics that have been trapped by currents. It is estimated to be twice the size of Texas, and according to research, its contents are rapidly accumulating.

Greenhouse Gas Emissions Are No Joke

When disposable plastics degrade in the environment, they emit greenhouse gasses. After the plastic is exposed to sunlight, it produces methane and ethylene. These two gasses are detrimental to the environment. It is reported that emissions from the life cycle of plastic accounts for 3.8% of global greenhouse gas emissions.7 Once released, these gasses can be toxic and have adverse effects on the animal and plant habitat.

It is estimated that in 2050, carbon dioxide (CO2) emissions from plastic could grow to more than 2.75 billion tons. Additionally, this also means that plastic will be responsible for up to 13% of the total “carbon budget,” which is equivalent to 615 coal-fired power plants.8 The plastic binge we’ve been on is threatening the Paris Agreement, which is a legally binding international treaty on climate change.

Other Harmful Single-Use Materials

Single-use items aren’t always packaged in plastic. There is a multitude of other unsustainable materials that are also heavily used and just as detrimental to the environment. A few of these materials that you likely come across daily are:

  • Cardboard: Think about how many boxes you receive on your doorstep step every month. It’s probably more cardboard than you think. Cardboard comes from wood pulp, which contributes to methane emissions while breaking down.9 Plus, imagine all of the trees cut down to create cardboard. Additionally, those juice, milk, soup and other liquid-filled cardboard packages we buy are lined with plastic or wax. This helps them retain the liquid without breaking down, but unfortunately renders the packages unrecyclable.
  • Paper: A paper bag takes 4 times the amount of energy to produce than a plastic one. Also, the energy required for paper is significantly greater than that needed to recycle the same weight of plastic.
  • Styrofoam: Styrofoam is a trademarked brand name that has come to refer to the material made from expanded polystyrene foam (EPS) or plastic foam. Styrofoam doesn’t break down properly, as it takes around 500 years to decompose.10
  • Aluminum Foil: Many food products and face masks are packaged using aluminum foil. Clean aluminum foil can be recycled, however much of the foil packaging that is used for personal care tubes, wipes, sheet masks, frozen foods, snacks, and coffee is multilayered with plastic fused to the aluminum. Some packaging is made of up to seven layers of plastic and foil. Currently, there is no machinery to separate these layers, so it becomes completely unrecyclable.
  • Glass: While glass includes some natural materials, it also requires sand. Unfortunately, we are running out of sand around the world. When these elements are removed from wildlife habitats, ecosystems can be disrupted. Glass production also releases carbon into the atmosphere.11

What Are The Most Offending Single-Use Items?

Avoiding extra waste is key to reversing the environmental crisis we are currently facing. It is hard to avoid single-use items these days; however, many companies are creating innovative alternatives. By becoming aware of the negative impacts of single-use packaging and how commonly we succumb to them, the change can begin.

Here are a few of the worst offending single-use items and their alternatives:

Plastic Water Bottles

Did you know that around 25% of bottled water is actually just tap water?12 80% of plastic water bottles end up in landfills. And for each bottle, it takes 1,000 years to fully break down. As they decompose, they leak harmful chemicals into the atmosphere.

Alternatives: Opt for a reusable water bottle and invest in a tap filter at home or a filtering jug. Check out this reusable water bottle that is made out of 50% recycled material!

Paper Coffee Cups

Each paper cup, taking into account the paper, the sleeve, the production, and shipping, emits around 0.11 kilograms of CO2.13 Additionally, paper cup production results in ecosystem degradation, a reduction of the planet’s carbon absorption capacity, and the loss of trees. 4 billion gallons of water are wasted every year to produce single-use cups and enough energy to power 54,000 homes.14

Alternatives: Bring your own reusable travel mug to your favorite coffee shop in the mornings. Here’s one that is insulated and has a handle so the barista can pour your drink of choice with ease.

Disposable Utensils

It is estimated that in the United States alone, 40 billion plastic utensils are wasted every year. Plastic utensils, even when put in the recycling bin, don’t often get recycled because of food contamination and incompatibility with sorting equipment due to their small size and light weight.15

The #CutOutCutlery campaign is asking many businesses, such as Grubhub, Postmates, and UberEats, to include an option on apps for customers to decide if they want utensils included with their delivery. This would make opting out of disposable utensils the default choice.

Alternatives: There are lots of biodegradable utensils available, such as this set that’s made out of 100% untreated bamboo that’s cultivated without pesticides and fertilizers. The utensils are also BPA-free and recyclable.

Menstrual Products

Around 20 billion tampons and pads are dumped into the landfill every year. Conventional pads contain the equivalent of about four plastic bags! Additionally, the polyethylene plastic in pads can take hundreds of years to decompose.16

Alternatives: Invest in reusable pads. Try grabbing some from Rael, which is a great mission-driven brand. You can also try a menstrual cup from DivaCup if you aren’t a fan of pads.

Plastic Straws

You’ve probably seen the viral video of the sea turtle that had a plastic straw stuck in its nose. It was horrible to see, but it probably made you rethink using plastic straws. As it is, 500 million straws are used daily in the United States.17 Due to the chemicals that most straws are made of, they can’t be recycled. Additionally, the majority of plastic straws are not biodegradable and cannot be broken down naturally by bacteria and other decomposers into non-toxic materials.

Alternatives: FinalStraw created an innovative alternative to plastic straws by making a reusable silicone and stainless steel hybrid straw. It also collapses to make keeping it on hand easier.

Tips to Avoid Single-Use Items

Making simple swaps, like purchasing a reusable water bottle, coffee container, or straw, can spare the environment tons of unsustainable waste each year. Here are a few tips for ridding your life of single-use items for good:

  • Always have reusable bags on hand, especially for grocery shopping.
  • Cook at home more often to avoid plastic take-out containers.
  • Buy in bulk to keep away from individually packaged items.
  • Walk, bike, or take public transportation to buy items and avoid unnecessary packaging used during shipping.
  • Ask for non-plastic alternatives at restaurants.
  • Avoid plastic wrap by using reusable containers to keep your food fresh.
  • Speak out and let companies know that you care about packaging!

We’ve Signed the #StopSingleUse Petition

The Human Beauty Movement and Humanist Beauty have had the last straw. We’ve signed the #StopSingleUse petition and pledged to not sell or distribute any items that are used once and thrown away, such as sheet masks, pads, wipes, sample packets, and other single-use products. We are very aware of how single-use items negatively impact the environment and are actively striving for a cleaner, more sustainable planet.
