Bioplastics Are Biodegradable Materials Made From Renewable Resources That Reduce Pollution And Suffocate The Environment

 

Bioplastics 

Bioplastics are made from renewable resources such as sugarcane, corn, cellulose, and other grains. They are environmentally friendly and are in high demand from a variety of industries. Bioplastic is widely used in food packaging, disposables, containers, pouches, shopping bags, and other applications. Green products, a healthier lifestyle, and environmental sustainability are becoming increasingly popular.

Bioplastics are plastic materials made from renewable biomass sources such as vegetable fats and oils, corn starch, straw, woodchips, sawdust, recycled food waste, and so on. Some Bioplastics are produced directly from natural biopolymers such as polysaccharides (e.g. starch, cellulose, chitosan, and alginate) and proteins (e.g. soy protein, gluten, and gelatin), while others are chemically synthesised from sugar derivatives (e.g. lactic acid) and lipids (oils and fats) derived from plants or animals, or biologically produced through sugar or lipid fermentation. In contrast, common plastics, such as fossil-fuel plastics (also known as petro-based polymers), are derived from petroleum or natural gas.

One advantage of Bioplastics is their lack of reliance on fossil fuel as a raw material, which is a limited and unevenly distributed resource linked to petroleum politics and environmental impacts. According to life cycle analysis studies, some Bioplastics can be manufactured with a lower carbon footprint than their fossil counterparts, such as when biomass is used as a raw material as well as for energy production. Other Bioplastics' processes, on the other hand, are less efficient and have a higher carbon footprint than fossil plastics.

The distinction between non-fossil-based (bio)plastic and fossil-based plastic is largely irrelevant because materials like petroleum are simply fossilised biomass. As a result, whether a plastic is degradable or non-degradable (durable) is determined by its molecular structure, not by whether or not the raw material is fossilised. There are both long-lasting Bioplastics like Bio-PET and biopolyethylene (bio-based analogues of fossil-based polyethylene terephthalate and polyethylene) and biodegradable Bioplastics like polylactic acid, polybutylene succinate, or polyhydroxyalkanoates. To avoid plastic pollution, Bioplastics must be recycled similarly to fossil-based plastics; "drop-in" Bioplastics (such as biopolyethylene) fit into existing recycling streams.

Although biodegradability may provide an end-of-life pathway in some applications, such as agricultural mulch, the concept of biodegradation is not as simple as many believe. Because biodegradability is highly dependent on the chemical backbone structure of the polymer, and different Bioplastics have different structures, it cannot be assumed that Bioplastics in the environment will readily disintegrate. Biodegradable plastics, on the other hand, can be made from fossil fuels. Bioplastics accounted for approximately 2% of global plastics output (>380 million tonnes) in 2018. With continued Bioplastics research, investment in bioplastic companies, and increased scrutiny on fossil-based plastics, Bioplastics are becoming more dominant in some markets, while fossil plastics output is steadily increasing.
