Plastic is everywhere, and it's hard to escape using it. Plastic accounts for 20-25% of the waste generated by US healthcare facilities, and Americans throw out about three-quarters of a pound of plastic per person per day. Plastic pollution is a huge problem, with plastic waste found in oceans, rivers, beaches, and the food chain. While some countries are taking steps to reduce plastic use, such as banning plastic bags or pledging to reduce virgin plastic use, the plastic industry continues to rely on fossil fuels as a feedstock. However, there may be ways to produce plastic without using fossil fuels, such as using sugars, methanol, or biomass. The challenge is to make these fossil-free plastics cost-competitive with traditional plastic production methods.

What You'll Learn
Plastic alternatives
Plastic is derived from petroleum products, and while we will eventually run out of oil, it is unlikely that we will run out of ways to make plastic. Petroleum-based plastics are so common because they are incredibly cheap to produce, chemically versatile, and durable. However, plastic waste is a major contributor to pollution, and there is a growing need to find sustainable alternatives.
One alternative is to simply reduce the use of disposable plastic by adopting reusable and refillable packaging or buying unpackaged goods. This approach requires a shift in consumer habits and behaviour.
Bioplastics, or plastics made from renewable biomass, are another alternative. Bioplastics are derived from plant sugars and oils, such as corn starch, wheat, potatoes, soybean, and cotton. They are biodegradable, but they are not without their drawbacks. Bioplastics can take up land needed for food production, and they require high-temperature industrial composting facilities for disposal. Additionally, bioplastics are currently very expensive to produce, and it is challenging to scale up production.
Other natural materials, such as coconut fibre, hemp, husk, oat hulls, cotton burs, and jute, can be used as packaging and shipping materials. Silicone, derived from silica stone, water, and natural gas, is another alternative that shares many physical characteristics with plastic but is considered safer and more environmentally friendly.
Researchers are also exploring innovative solutions, such as an anti-microbial and biodegradable spray-on coating made from plant cellulose for produce and food items. This spray is designed to be rinsed off with water and degrade in soil within 3 days, eliminating the need for plastic packaging.
While there is no single magic solution, a varied approach that includes sustainable alternatives and a reduction in plastic usage can help address the plastic crisis.

Plastic usage reduction
Plastic usage and plastic pollution are two of the most pressing environmental issues facing the world today. Plastic is cheap to produce, and its unique chemical properties make it indispensable in medical settings. However, plastic pollution is endangering marine life, terrestrial animals, and even human health.
- Avoid single-use plastics such as plastic bags, straws, cups, plates, utensils, and food containers. These items are used once for mere minutes but will remain on the planet for hundreds of years as plastic does not biodegrade.
- Opt for reusable alternatives, such as cloth napkins, reusable dishes, glasses, silverware, and reusable containers for packed lunches.
- When shopping, bring your own reusable bags and try to buy items with minimal packaging.
- Purchase products made from recycled plastic materials, such as bubble wrap containing recycled plastic.
- Buy items packaged in aluminum or glass rather than plastic. Aluminum cans and glass bottles and jars are infinitely recyclable.
- Maintain and repair plastic products so they don't have to be thrown out and replaced as frequently.
- Sell or donate unwanted plastic items that are still in good shape so that others can reuse them.
- Choose products with natural exfoliants, like oatmeal or salt, instead of microplastics.
- Support restaurants and businesses that use reusables over disposable plastics.
- Check with your local recycling program to find out which types of plastic they accept, and recycle plastic bags, wrap, and film at designated drop-off locations.
- Support policies and initiatives that aim to reduce plastic usage and increase recycling, such as the Plastic Pollution Reduction Act.

Plastic collection methods
Plastic pollution is a pressing issue, with plastic waste being found in oceans, rivers, beaches, and the stomachs of marine animals. Corporations and governments are facing increasing pressure to reduce plastic usage and increase recycling efforts.
There are several methods for collecting plastic waste:
- Curbside collection: This is the most widely accessible method, where residents place recyclables in designated containers (large bins, coloured bags, or small open plastic tubs) at the curb for collection. This is convenient for community residents and yields high recovery rates.
- Drop-off recycling: Containers for designated recyclables are placed at central collection locations, such as parking lots, schools, or malls. Residents bring their separated recyclables to these locations, where they are further sorted by material type. This method is suitable when residents already bring their garbage to a central waste collection facility.
- Buy-back centres: These are usually operated by private companies that pay consumers for bringing in recyclable materials. These centres often have purchasing specifications, requiring consumers to source separate and specified recyclable materials.
- Deposit/refund programs: This method involves consumers paying a deposit when purchasing products in containers or with packaging that can be returned for a refund upon recycling. This encourages consumers to return their recyclables and reduces plastic waste.
- Household collection: This method focuses on collecting plastic waste directly from households, including door-to-door collection. It is more efficient than litter picking and can help prevent plastic from reaching oceans and rivers, addressing the root cause of ocean pollution.
- Ocean and river collection: Organisations recover plastic from oceans and heavily polluted rivers using various technologies, such as barge-like vessels, bubble barriers, mesh barrier systems, and waterwheels. While this method addresses existing plastic pollution in waterways, it is not as effective as preventing plastic from entering these environments in the first place.

Plastic production without fossil fuels
Plastic is everywhere, and it is a significant contributor to pollution. Over 99% of plastic is made from chemicals sourced from fossil fuels, and the plastic and fossil fuel industries are deeply intertwined. However, as the world moves towards reducing plastic pollution, the plastic industry is looking for ways to continue producing plastic without relying on fossil fuels.
The journey towards fossil-free plastic has just begun, and there are already many ways to create plastic without fossil fuels. For example, plastic can be made from sugar, methanol, or even fungi. Sugar-based plastics are known as bioplastics, and they are made from plant sugars and crop residues. Big manufacturers such as BASF, Dow, Huhtamaki, Plantic, Mondi, and Amcor are researching plastic production from corn, wheat, potatoes, soybean, and cotton. Bioplastics are also used in some medical sectors, although the levels are incredibly low.
Another way to produce plastic without fossil fuels is by using methanol, which can be made from renewable biomass or green hydrogen. Methanol is an important component in producing plastics, synthetic fibres, paints, adhesives, pharmaceuticals, and agricultural chemicals. As we move towards a net-zero economy, methanol is likely to become a crucial feedstock for plastic production.
While these methods of producing plastic without fossil fuels exist, there is still a significant price gap that needs to be addressed. Fossil-free plastics need to be cost-competitive to be scaled up and made mainstream. This can be achieved through subsidies, clients willing to pay more for green plastics, mandatory production targets for fossil-free plastics, or taxing current plastic production from oil or gas.
In addition to these alternative production methods, reducing plastic pollution can also be achieved through other means. Novel ways to collect plastic from rivers and oceans have been introduced, such as the Ocean Cleanup project's Interceptor vessel and Waternet's "bubble barrier" in Amsterdam's canals. Recycling and carbon capture and storage (CCS) technologies can also help mitigate the CO2 impact of plastics derived from oil and gas.

Plastic reduction challenges
One major challenge is eliminating single-use plastic, which accounts for a significant portion of plastic waste. Many countries and companies have pledged to reduce or eliminate their use of single-use plastic, and campaigns such as "Plastic Free July" have gained traction, challenging people to avoid using any plastic during the month of July. Another challenge is shifting to sustainable sources for plastic, such as bioplastics made from corn, wheat, potatoes, soybeans, or cotton. While bioplastics are a promising alternative, they face challenges such as competition for land with food production and the need for industrial composting facilities.
Additionally, improving recycling systems and increasing recycling rates is a significant challenge. This includes updating regulatory systems, establishing producer responsibility systems, and creating federal policies to promote circularity and improve recycling infrastructure. Standardizing recycling processes and creating clear guidelines can also help increase recycling rates.
Finally, there is a challenge in balancing the benefits of plastic in certain industries, such as healthcare, with the need to reduce plastic usage. Plastic is indispensable in medical settings due to its sterility, flexibility, and low cost, but alternatives must be found or developed to reduce the environmental impact of plastic waste. Overall, addressing these challenges requires a combination of policy changes, public support, and innovative solutions to reduce, reuse, and recycle plastic more effectively.
