Biodegradable Plastics could be the solution to the growing accumulation of hydrocarbon-derived plastics. With reports of growing amounts of plastic accumulating in the Earth’s oceans, not to mention landfills, there is a real need for some form of biodegradable alternative of plastics. This is where bioplastics and eco-friendly poly bags come into their own. Since these types of biodegradable plastics are made from natural raw materials they are also able to be degraded by nature, in some cases eaten – by you. The following types of biodegradable plastics’ solutions could replace regular hydrocarbon derived plastics in the not too distant future.
1. Biodegradable Plastics Can Now Be Made From Sugar and CO2
Scientists from the Centre of Sustainable Chemical Technologies (CSCT) at the University of Bath managed to make a type of biodegradable plastic. This eco-friendly plastic is made of sugar and carbon dioxide and not oil. It is made by combining a sugar called thymidine with CO2 at low pressures and room temperature.
2. Biodegradable Containers Can Be Made From Rice
Finnish researchers, in 2014, were able to use rice starch to make sustainable, biodegradable polymers. These polymers could then be used to make eco-friendly food packaging. Their biodegradable plastic also had a high degree of thermal resistance and mechanical strength.
3. Biodegradable Food Wrappers Can Be Edible
Earlier in 2018, researchers at the University of Otago have managed to develop biodegradable food packaging material made from corn and shellfish industry by-products. This is already great news but it gets better – this eco-friendly food packaging material would not cause any harm even if you consume it by mistake.
Their research will reduce our dependence on oil and other non-biodegradable plastics but also reduce waste by simply eating it rather than binning it.
4. Waste Frying Oil Can Be Converted to Eco-friendly Plastics
The types of biodegradable plastics belonging to the second generation can be made from used frying oil. This kind of oil is a great source of polyhydroxybutyrate that can be used to make bioplastics.
STU chemists have developed an idea for using bioplastics for sunglasses frames, the design that won the 2017 National Design Award. They are also waiting on a patent application for the process.
5. Banana Peel Could be Used to Make Bioplastics
In 2013, a Turkish teenager, Elif Bilgin, won the Science in Action Award for her concept of making bioplastic from banana peels. Elif managed to devise a chemical process for converting the peel into a resistant bioplastic that would offer a solution to reduce waste and our dependence on oil for plastics.
6. Avacado Based Biodegradable Straws Are a Thing Now
A Michoacán based company, Biofase, are converting 15,000 tonnes of avocado seeds into bioplastics every day. The company’s process was devised by its founder, Scott Mungía, who was looking for an abundant raw material to make bioplastics.
7. Biodegradable Plastics Can Now Be Made From Shrimps
Not only are shrimps tasty to eat but their ‘waste’ shells can be used to make bioplastic and eco-friendly plastic bags. Their shells are made, primarily from a biopolymer called chitin (like many arthropods).
8. Seaweed Can Be The Ultimate Raw Material For Bioplastic
Most types of biodegradable plastics today are made from either corn, sugarcane, vegetable oil, and starch. But a lot of these are also foodstuffs – leading to potential competition.
Seaweed is, however, very abundant, rarely eaten, doesn’t require fertilizer an doesn’t take up land space to grow. It is the perfect non-food alternative for making bioplastics.
9. The Humble Masked Bee Already Makes types of Biodegradable Plastics
An Australian startup, Humble Bee, have found that the Australian Masked Bee’s (Hyleaus Genus) nesting materials could be a great source for making various types of biodegradable plastics. Unlike other bees, they don’t live in hives but their cellophane-esk nesting material is water repellent, heat resistant and chemical resistant.
Their research has received a lot of attention recently and they even managed to secure significant funding from New Zealand’s government agency Callaghan Innovation.
10. The Toys of the Future Could Be Made from Biodegradable Plastics
Two companies, Bio-on and Italeri are currently collaborating on Minerv Supertoys to make their toys of the future from various types of biodegradable plastics. Bio-on’s bioplastic is 100% biodegradable polymer and is completely natural.
Their work has had some encouraging results and they plan to take their PHA-based (polyhydroxyalkanoates) toys to market very soon.
11. Lego Have are using Bio-based polymers in their products
Lego Kits now contain several types of biodegradable plastics. They plan to introduce sugarcane-derived biodegradable plastics that will be limited, initially, to Lego trees, bushes, leaves, and other botanical elements.
Lego first announced the move in 2015 but have since committed three years of research and $1 billion in investment to make it a reality.
12. Algae and 3D Printing Could be a Match Made in Heaven
Two Dutch designers, Eric Klarenbeek and Maartje Dros, have developed types of biodegradable plastics that are made from algae. They are also convinced that, in time, it could completely replace ‘synthetic’ plastics.
It doesn’t end there. The algae are cultivated, then dried and processed, ready for use in 3D printers.
13. Recycled Ocean Plastic and Deep Sea Gillnet Shoes
Although not technically a bio-plastic application, Adidas released a prototype for new sneakers in 2015. This might not sound groundbreaking, but the critical thing is that the products are made from recycled ocean plastic and deep-sea gillnets.
They reduce waste, clean the oceans and provide you with a new pair of shoes all in one go and for ‘as little’ at $200.
Well, this doesn’t end here. Oxygreen Plastics are into biodegradable food packaging, shopping bags and many more products that involve a plastic additive Oxygreen, accelerating Plastic Degradation into Nature.
