Bio Plastics

Anny | Jan 06, 2021

We all use plastics in our daily life in a vast number of ways such as in household appliances, wrappers, containers, etc. One advantage of plastics is that it can be easily manufactured and molded into a variety of shapes and sizes.  Discarded plastics container scan again be recycled and made into a new product. However, most of the left-over and discarded plastic waste often ends up in a landfill or is incarcerated which gives a lot of noxious fumes that pollute the atmosphere.

Plastic waste has been deemed to be one of the most polluting of all waste materials as its synthetic nature does not allow it to degrade into the soil. There has been a focus on alternatives to using plastics, and one such alternative is the usage of bio-plastics-which are derived from biological sources and are degradable.

Bioplastics are commonly made from natural substances such as corn, vegetable fats, etc. They are two different broad applications in using bio-plastics. One is to create a biodegradable form of plastic that easily disintegrates and does not cause environmental pollution. The other is to create plastic polymers from a natural source-thereby decreasing our dependence on petrochemicals and chemical sources of plastics.

Some examples of bioplastics are as below.

PLA – Derived from cane sugar: It can be made into foils, molds, cups, and bottles. PLA can be easily processed and is similar to conventional plastics.

Cellulose-based plastics-derived from common cellulose. Ex-Cellulose acetate

Thermoplastic Starch: This is one of the most widely used bioplastics and is derived from natural starch and similar substances. They are often blended with other varieties of bio-plastics and have diverse uses.

Renewable polyethylene: PET is one of the most widely used varieties of plastics, and also is one of the most polluting materials in recent times. Ethanol derived from natural sources can be made into PET, as ethanol is one of the building blocks of PET. Natural ethanol can be derived from a large number of sources such as sugarcane, corn, etc. Sourcing the basic material from a natural source would significantly decrease the amount of pollution and the carbon footprint in making commercial ethanol.
