Bioplastics are are made out of natural materials, and are easily degradable. Thus, they cause little harm to the environment. The conventional plastics are products of chemicals from fossil fuels which are energy intense and green house emission. This creates a need to alternative plastics.
How does BioPlastics Function and Benefit?
Bioplastics are not new in the market; they already exist either wholly or partially. They are called bioplastics because they are made from natural materials. Several bioplastics can biodegrade; however they need industrial composting settings to do so.
Some of the bioplastics cannot biodegrade, but, they can act as a usable substitute for traditional plastics and are recyclable. One of the classic examples for the same is bio- based polyethylene terephthalate (PET). Coco Colas PET bottles are a product of sugarcane residue; they are not biodegradable but fully recyclable.
On the contrary, the bioplastics also comprises of plastics from oil and can be biodegradable too. Polybutyrate adipate terephthalate (PBAT) is a bio plastic from oil. Further, manufacturers use it to make compostable shopping bags.
Plastics using raw materials such as sugarcane, corn, and sugar beet pulp are gaining popularity. We call these plastics polylactic acid (PLA), and industries in food manufacturing use to make containers and cans. This comes across as a solution for packaging waste for adulteration with food residues that is not recyclable. However, if people use them for serving meals, it is possible to dispose them in a factory composite setting.
Researchers call this as ‘Zero Waste’ approach for out-of-home catering services. Many hotels, restaurants, and canteens are adopting this approach across U. K.
