Plastic Alternatives

Scientists around the world are developing innovative and exciting new alternatives to plastic. There are now ways that we can wrap, carry, and preserve our products just as we always have, but without damaging the Earth.

Nearly 400 million tonnes of plastic waste gets into air, water and soil every year.

The TeamSeas Robot works at cleaning up this plastic pollution in the ocean , and plastic-eating bacteria is being developed to clean plastic waste up on land.  But the fact is that these solutions don’t target the source. They can only be so effective if plastic keeps being thrown into the environment.

In comes plastic alternatives.

What Are Plastic Alternatives?

Plastic alternatives are materials that replace traditional plastics. There are dozens of plastic alternatives, and they can all be categorized in two ways: traditional plastic alternatives and innovative plastic alternatives.

Traditional plastic alternatives have been used for centuries and became ubiquitous with plastic use; whereas innovative plastic alternatives are new and compete with plastic as a more sustainable alternative.

Here are the top 5 genius plastic alternatives that—while new and expensive—can help save the planet by reducing plastic pollution.

Zerocircle: Plastic Alternatives from Seaweed

Seaweed has been protecting the ocean since long before human beings have been wandering the world. It only seems logical to let it keep doing that. That’s what entrepreneur Neha Jain figured when she founded Zerocircle in 2020.

Seaweed is an easily renewable resource available in most of the oceans of the world. They provide as much as 50% of the oxygen in the atmosphere and play a vital role in the health of our planet.

Zerocircle uses these plants to develop and distribute an exciting seaweed-based plastic alternative. It quickly dissolves back into water and soil, leaving no harmful chemicals behind.

WasteBased: Plastic Alternatives from Hydropol

Easily one of the biggest challenges in the battle against plastic pollution is the everyday plastic shopping bag. Wastebased, a UK-based startup has introduced an answer to that problem.

Item Bag 2.0 “… is no ordinary bag,” says their website. “It will dissolve in fresh or saltwater and leave no microplastics behind. It’s also biodegradable, non-toxic, and carbon negative.” It also dissolves in boiled water leaving no harmful chemicals behind.

Rather than the usual chemicals and polymers that traditional shopping bags are made of—like forever chemicals—Item Bag 2.0 is made from Hydropol. This biodegradable bioplastic is similar to the material used to coat dishwasher or laundry pods. Presently, it’s being manufactured from fossil fuels, but they can also be made from renewable resources such as sugar cane. Wastebased is currently working toward making the switch.

Plastic Alternatives from Potatoes

Another great idea is coming from a man at Lund University in Sweden. It’s a plastic alternative made of just potato starch and water. The potato plastic decomposes within only two months of landing in the environment. That’s a huge improvement over the 500 years it takes traditional plastics to break down.

Pontus Tornqvist, the developer of the material, took it one step further. The plastic not only breaks down quickly, but because it’s made of potato material, it actually nourishes the soil it lands in. As Pontus puts it, it’s just better to use the waste we’re already creating than to make new waste.

Ecovative: Plastic Alternatives from Mushrooms

Ecovative is a company that specializes in making packaging out of mushroom material which they grow in their own facility. They create a packaging solution with the natural binding properties of the roots of mushrooms. The solution, known as Mushroom Packaging, can be added to the compost heap to biodegrade safely and quickly into the Earth. More than that, the fungus content of the material will nourish the soil around it.

Paptic: Plastic Alternatives from Wood Fibres

Finland has another good idea about innovative plastic alternatives. Paptic is a growing company that uses a plastic, paper, and canvas alternative made from wood fibers.

They use only forests that produce more trees than they need and with careful attention to biodiversity and the natural world. The resulting product is reusable, recyclable, and biodegradable. It’s already been commercially available for several years.

Wood fiber plastic is used to make a wide variety of sturdy products including bags, food packaging, and mailers. This plastic alternative is likely to be stronger than that of plant-based alternatives.

Are Plastic Alternatives Better for the Environment?

Traditional plastic alternatives like paper, wood, and glass are heavier than plastic and release more greenhouse emissions during production. This increase in GHG emissions make traditional plastic alternatives worse for the environment than plastic. However, some innovative plastic alternatives like seaweed have natural elements that break down in the environment over time. This makes bioplastic alternatives better for the environment because it reduces plastic pollution.

The only problem is that bioplastics remain expensive to produce. This makes it difficult to gather the data needed to understand how much GHG they emit during production, and whether it is less than plastic alternatives.

Why Are Bioplastic Alternatives Expensive?

Many bioplastic alternatives are plant-based. They are made from materials that don’t just require processing like traditional plastic, but that also require growing and harvesting. Moreover, they are not widely available, and their scarcity in comparison to plastic further raises their price. All of these factors— including that they are also new—make bioplastic alternatives expensive.

Bioplastic Alternatives Are Increasing

Research and development is the key to making Bioplastics widely used. If renewable energy has taught us anything, its that things become less expensive as we continue to use them because we get better at producing them. While bioplastic make up less than 1% of the plastic currently used, its production and refinement is increasing every year.

The global production capacity of bioplastics increased to 2.6 Billion metric tons in 2024, a 22% increase from 2023. This number is expected to quadruple in 2025. If this happens, it will be the biggest yearly increase in bioplastic production ever.

Drawbacks of Plastic Alternatives

There are some challenges for adopting many of these alternatives to plastics.

• GHG Emission: Plant-based plastic alternatives require growing and harvesting in addition to manufacturing. These added layers to the production process may increase GHG emissions.
• Inefficient Production: Many innovative plastic alternatives, like seaweed, require manual processing. This takes up a lot of time and adds to the cost.

• Pesticides: Plastic alternatives made from plant materials carry with them the risk of pesticide contamination. This is something that could be remedied using AI agricultural robots in the future.
  
• Methane: Bio-based plastics alternatives are not entirely biodegradable. They are only partly made from bio-materials. When these alternatives get thrown in landfills, they can produce methane which will aggravate the global warming problem. However, this is also true of traditional plastic.
  
• Higher Cost: Some bioplastics cost 20% to 50% more to produce than traditional plastics making them financially unsustainable.
  

There is no perfect solution to plastic pollution, but the development of all these possible plastic alternatives is inspirational and brings with it some amazing innovations for the future. It’s only a matter of time before we find the best solutions to plastic pollution.

Seaweed Plastic

Every minute, two garbage truck’s worth of plastic enters our oceans.

And every other minute, thousands of people across the world dedicate themselves to creating low-cost, biodegradable plastic alternatives that dissolve as soon as it enters the ocean.

This spells good news for the future of our human underwater habitats.

What is Seaweed Plastic?

Seaweed plastic are plastic alternatives that are made from seaweed, and that are bio-degradable. This means that when any of these “plastics” reach the ocean, it will dissolve as soon it touches the water. Moreover, seaweed is also edible, making seaweed plastics less likely to end up in oceans because there is an option that it might end up in the stomach of users.

Who Invented Seaweed Plastic?

The Idea of a seaweed plastic alternative was developed by engineering college students Rodrigo García González, Pierre-Yves Paslier and Guillaume Couche. They were the first to invent the “edible water bottle”, a sachet made from seaweed which contains water, and which was sold by the startup Ooho. in 2019, Ooho rebranded to the name Notpa, and has since included food packaging, rigid cutlery and containers among their bioplastic products.

What are the Disadvantages of Seaweed Plastic?

• High Cost: Production costs are high for seaweed plastics, making their demand low and their production limited.
• Less durable: Seaweed plastic alternatives are biodegradable, but they have weak mechanical properties compared to traditional plastics. This makes them less durable, and more prone to tearing.
• Limited Applications: Seaweed plastics currently have a very limited use and are often restricted to gift and food wraps, tea bags, and sachets; whereas, conventional plastics can be used for almost everything.

What are the Advantages of Seaweed Plastic?

Less than 10% of plastics actually end up being recycled. This makes seaweed plastic alternatives much more practical as a solution to plastic pollution than recycling. The advantages of seaweed plastic alternatives include the following:

• Biodegradable: Traditional plastics can take centuries to decompose; however, plastics made from seaweed dissolve as soon as it reaches the ocean.
• Edible: Bioplastics made from seaweed don’t need to reach the ocean in the first place because they can be eaten. Imagine receiving a gift-wrapped present in the near future and knowing that if you wanted to, you can have your gift and eat it too.
• Carbon Capture: Seaweed cultivation absorbs carbon dioxide from the atmosphere, helping mitigate the affects of climate change and create a clean energy future.
• Healthier Oceans: It is estimated that algae produce up to 70% of Earth’s oxygen. If seaweed plastics end up reaching the ocean, it will contribute to a healthy environment for both terrestrial and marine life—assuming nobody eats their grocery bag first.

Can Seaweed Replace Plastic?

Seaweed is indeed replacing plastic, but not to the extent where it is currently making a large difference in reducing plastic pollution. Startups like Mumbai-based Zerocircle are creating tea bags, burger wrappers, gift wraps, and grocery store bags from seaweed plastic; however, while seaweed plastics are good for some applications, they are not likely to completely replace plastic.

Zerocircle received $200,000 from the Tom Ford Plastic Innovation Prize for bringing to life a bio-degradable alternatives to plastic films. Lonely Whale in association with TOM FORD BEAUTY and The Estée Lauder Companies have also helped the startup receive widespread market adoption.

While still in its early stages, production methods for seaweed-based bioplastics are evolving. We will see more of these plastic alternatives being used in the future as its uses become more versatile.

Archangel Ancient Tree Archive

Archangel Ancient Tree Archive (AATA) is a non-profit organization that locates and then clones the world’s most ancient trees. They do this to propagate the powerful DNA of these ancient trees—which they say can cool down the earth 10 times faster than ordinary trees can.

Where is the Archangel Ancient Tree Archive?

Volunteers at Archangel have successfully cloned over 150 ancient trees and then planted tens of thousands of these trees in over 7 countries including France, the US, and New Zealand. Trees act as powerful carbon stores, and that is part of the reason why such great emphasis is put on regrowing forests to stop the climate crisis.

History of Archangel Ancient Tree Archive

In 2008, co-founder David Milarch embarked on a journey to save the last remaining population of old-growth trees after a life-long battle with alcoholism led him to a near-death experience.

A day came when he was so fed up with the life he was living that he left his bottles of alcohol outside his room door and locked himself in. He made a strong promise to himself that he would not come out until the alcohol was completely out of his system…

3 days later his kidneys began to fail, and he ended up in the emergency room.

When he woke up, he said he was revealed a mission: clone ancient trees and then plant them. Ever since, the Archangel Ancient Tree Archive has located the remaining 2% of the largest and oldest living trees on the planet and began cloning them, then preserving their genetics in a “Living Library”.

This living library preserves the genetics of these trees by species, safeguarding the DNA and genetic heritage of the sort of trees that grow 10 times faster than current generations. Trees that grow 10 times faster will help in recovering forests lost to deforestation and forest fires 10 times quicker, creating lusher forests, and contributing to the planet’s health at a rate that is faster than the descendants of these trees.

Champion Trees of the AATA

David Milarch’s family and numerous volunteers of the Archangel Ancient Tree Archive have called these trees “Champion Trees”. The idea is that by planting them, these Champion Trees go on to share their genetics with existing trees, which strengthens the forests’ ability to store carbon and preserve habitats.

In their YouTube video “About Archangel Ancient Tree Hive”, Dr. William J. Libby, science advisor at Archangel expresses: “What we are doing is, we are not changing the genetic constitution of any trees. In fact, we are trying to capture that so it can be studied in the future without being changed.”

How do you Clone Ancient Trees?

Volunteers climb to the top of these trees, trim the ends of the branches from a height not yet touched by any chemicals or new hormones, and send the cuttings to their Michigan facility so that cloning can begin.

This entire process of cloning, archiving, and then reforestation, has become a healing system for the entire planet, thanks to the efforts of David Milarch and this motivational organization.

How Does the Archangel Ancient Tree Archive Help Forests?

In 2020 the devastating Castle Fire took away half of the ancient trees in Sequoia Crest in California, which is home to the oldest living trees on the planet. These trees were presumed to be immune to fires. 

However, AATA foresaw the possibility of such an event happening due to rising temperatures and had been working for a decade before the event to collect material and clone these ancient trees from American forests. Ultimately, these seedlings helped the team to quickly rebuild the burnt area of the forest and provide new life to these giant Champion Trees, and the habitats that come with them.
