What You'll Learn
Bioplastics: made from natural substances, not petroleum
Bioplastics are biodegradable or compostable plastics made from natural substances such as shellac, cellulose, corn starch, rice starch, or chitosan instead of petroleum. They are often touted as being eco-friendly, with reduced use of fossil fuels, a smaller carbon footprint, and faster decomposition. Bioplastics are also said to be less toxic and do not contain bisphenol A (BPA), a hormone disruptor often found in traditional plastics.
The concept of bioplastics dates back to the early 20th century, with significant advancements occurring in the 1980s and 1990s when researchers began developing biodegradable plastics from natural sources. Today, bioplastics are gaining interest again in the context of the bioeconomy and circular economy. Companies like Minnesota-based NatureWorks are producing polylactic acid (PLA) under the brand name Ingeo, which is commonly used for medical applications and single-use food packaging.
However, it is important to note that most bioplastics do not break down in home composts, landfills, or loose in the environment. They typically require commercial composting facilities, which are not always accessible to the average consumer. Additionally, bioplastics can contaminate municipal recycling programs when people unknowingly add them to their recycling. Furthermore, a 2010 study from the University of Pittsburgh questioned the eco-friendliness of bioplastics, finding that bioplastics and conventional plastics have similar levels of toxicity.
While bioplastics have their advantages, it is clear that they are not a perfect solution to the problem of plastic pollution. Nevertheless, with the world having produced over nine billion tons of plastic since the 1950s, and single-use plastic continuing to be a huge presence in supply chains, it is important to explore a range of alternatives to traditional plastic, including bioplastics, to create a more sustainable future.

PHA: a compostable, biodegradable alternative to traditional plastic
The world is awash with plastic, and its presence is a huge problem for the future of our planet. Single-use plastic is everywhere, from our appliances, computers, and clothing to the packaging of everyday items. However, there are many plastic alternatives available to consumers and businesses, and more are being developed all the time.
One such alternative is PHA (polyhydroxyalkanoates), a type of bioplastic. PHAs are biodegradable, compostable, and non-toxic, making them an excellent alternative to traditional plastic. They are produced by numerous microorganisms, including through bacterial fermentation of sugars or lipids. PHAs are also biocompatible, meaning they can be implanted in living human tissue.
PHAs have robust mechanical qualities comparable to those of thermoplastics derived from petroleum. They can be thermoplastic or elastomeric materials, with melting points ranging from 40 to 180°C. They are also UV stable, in contrast to other bioplastics. The mechanical properties and biocompatibility of PHA can be altered by blending, modifying the surface, or combining PHA with other polymers, enzymes, and inorganic materials. This versatility allows for a wider range of applications.
PHAs are more expensive to produce than traditional plastics, which has hindered their widespread adoption. However, researchers are working on new technologies and materials to reduce the costs. For example, some companies are using wastewater and cheese-making byproducts as feedstock for microorganisms to produce PHA. As production methods improve and costs become more competitive, PHAs have the potential to be used across various industries, including medical, automotive, packaging, and agriculture, providing a sustainable alternative to traditional plastics.

Cloth: cotton and hemp bags are washable and sustainable
Cloth bags made from cotton and hemp are washable and sustainable alternatives to single-use plastic bags. They are biodegradable, reusable, and made from natural and renewable sources. Cotton and hemp bags are also durable and can be used multiple times, reducing the amount of waste generated.
Cotton bags are made from natural and renewable sources and are biodegradable, but they have a high demand for water, pesticides, and space. According to a 2018 study, a single organic cotton bag would need to be used 20,000 times to offset its environmental impact. This is because of the large amount of energy and water required to produce these bags. For example, producing 1kg of cotton textile requires 10,000-20,000 liters of water. Therefore, the environmental benefits of cotton bags are only apparent when a single bag is used over a long period.
Hemp bags are a more sustainable alternative to cotton bags. Hemp is a fast-growing crop with a shorter growth cycle of 90-120 days, and it can be grown on the same land for about two decades without stripping the soil of its nutrients. Hemp is also drought-tolerant, thriving without the need for fertilizers or pesticides, and it replenishes soil quality as it grows. Additionally, hemp is a robust and durable material, making it an excellent, eco-friendly substitute for plastic bags. An acre of hemp produces 1300 pounds of fiber on average, while cotton yields less than 800 pounds. Hemp bags are also cheaper to produce than cotton bags, making them a more cost-effective option for consumers.
The use of cloth bags, especially those made from hemp, can significantly reduce the amount of plastic waste that ends up in the environment. By encouraging the use of reusable cloth bags, we can take a step towards reducing our reliance on single-use plastics and promoting a more sustainable future.
