Types of biodegradable plastic | What does biodegradable mean

Nowadays, Sustainable living is the most common word people are interested in after this pandemic because of the oxygen shortage they learn many things.

People get to know the importance of the environment & why its protection is required.

Here we will share a detailed guide about types of biodegradable plastic. What is it?

How this will help to make you & your surroundings more environmentally friendly so you can go towards adopting sustainable life after knowing this term.

What does biodegradable mean

Biodegradable is the property of any substance which denotes that the substance or material can be disintegrated or not & Able to convert into compost by using natural resources like sunlight, water, bacteria, etc.

Here are some examples of biodegradable materials present in our surroundings.

  1. Food waste( organic waste of fruits & vegetables, grains)
  2. Green waste (Plants, flowers, leaves, wood)
  3. Bodies of humans, animals, birds
  4. Paper wastes
  5. Sewage

What is a biodegradable plastic

Biodegradable plastic is a newly designed plastic that is created by focusing on the harmful effects of plastic. These are the plastics that can be decomposed in the presence of bacteria as do with other organic materials.

Usually, plastic is a material that is considered a non-biodegradable material but the technology goes too far & because of that science has successfully created a plastic that is included in the list of biodegradable materials.

Shocking!! But true

These types of biodegradable plastics will take approximately 6 months to break down but can’t find an estimated time.
Hence, it will not harm the environment.

Types of biodegradable plastic

Understanding the concept of biodegradable is much tougher but still, we are trying to make it as simple as possible so you will get the difference between all types of biodegradable plastics.

According to our research, we found few types of biodegradable plastics are there:-

Polyhydroxyalkanoates (PHAs)

Polyhydroxyalkanoates belong to a class of biodegradable plastic naturally produced by various microorganisms. The biosynthesis of PHA is usually driven by depriving some organisms of certain nutrients and supplying an excess of carbon sources.

Polylactic acid (PLA)

Polylactic acid is a thermoplastic aliphatic polyester synthesized from renewable biomass, typically from fermented plant starch such as corn, cassava, sugarcane, or sugar beet pulp.

Starch blends

Starch blends are thermoplastic polymers that are produced by blending plasticizers. While all starches are biodegradable, all plasticizers are not. Therefore, the biodegradability of the plasticizer determines the biodegradability of the starch blend.

Cellulose-based plastics

Cellulose bioplastics are essentially the cellulose esters (including cellulose acetate and nitrocellulose) and their derivatives, including celluloid. Cellulose can become thermoplastic when extensively modified.

Lignin-based polymer composites

Lignin-based polymer composites are bio-renewable natural aromatic polymers along with biodegradable properties. Lignin is also a byproduct of polysaccharide extraction from plant material through paper, ethanol, and more.

Petroleum-based plastics

Petroleum-based plastics are derived from petrochemicals obtained from fossil crude oil, coal, or natural gas. The most widely used petroleum-based plastics such as polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), and polystyrene (PS) are not biodegradable.

Polybutylene succinate (PBS)

Polybutylene succinate, i.e., PBS is a thermoplastic polymer resin that includes all properties comparable to propylene. It is commonly used in packaging films for cosmetics and food.

How does biodegradable plastic save the environment

Biodegradable plastic is made up of natural raw materials that will improve & affect many factors of the environment. The five advantages we shared below in which biodegradable plastic plays a vital role to save the environment.

Reduce the percent of carbon emission on world

The significant benefit is, it helps to decrease the percentage of carbon emission so much.
As we noted above it uses natural resources that will release less carbon during manufacturing in the industries.

Consume less energy

Although these biodegradable plastic needs less amount of energy during manufacturing comparatively the manufacturing of non-biodegradable plastic.

Produce less Waste

In the previous post as we discussed the waste segregation process & also talk about the plastic is spreading everywhere on the earth.

In India, millions of plastic wastes are produced from households every year that could be stopped to go into the landfills, oceans & save them for pollution that will happen due to biodegradable plastic.

However, biodegradable plastic has the characteristics to convert itself into compost it means the maximum waste problem will be solved automatically.

Reduce pollution

When the non-biodegradable plastic waste burns it releases many dangerous substances in the form of gas which harms the environment & affects living beings (Humans, Birds, Animals, etc.) health badly.

However By initiating the use of biodegradable plastic that will compost naturally in a short time without in the presence of chemicals than traditional plastic. Hence no-one won’t be able to burn plastics & the pollution will reduce.


The last advantage we add to the list is eco-friendly it will help to make your life sustainable & more eco-friendly.

Choosing eco-friendly products & add them to your daily life will put a positive impact on your health & you feel happier because you’re doing something good for the environment too.
