Why biodegradable plastic is important?

This blog post will answer the question, “Why biodegradable plastic is important” and cover topics like biodegradability of plastic and frequently asked questions related to the topic.

Why biodegradable plastic is important?

Biodegradable plastics are important because they degrade quickly, may be absorbed by the soil, and can even be turned into compost.

Biodegradable Plastic: What Is It?

A synthetic substance known as biodegradable plastic may deteriorate over time with the help of living things, ultimately decomposing into water, co2, and biomass as byproducts. 

Unlike other plastics, which might take hundreds or thousands of years to decompose, biodegradable plastic can break down organically over an organic period of time. 

Polyhydroxyalkanoates, Polylactic Acid, plant starch blends (such as maize starch), and cellulose-based polymers are a few of the known categories of biodegradable plastics.

What Differs Between Compostable Plastic, Bioplastic, and Biodegradable Plastic?

Between biodegradable plastic, bioplastic, & compostable plastic, there are a few key distinctions to be made:

  • Biodegradable plastic: Regardless of the source material from which it was made, biodegradable plastic refers to any plastic that may break down organically via the action of living things. 

Plastic may degrade without becoming a bioplastic or a “compostable plastic,” yet it can still be biodegradable.

  • Bioplastic: Bioplastic is a word used to describe any plastic produced from raw, naturally renewable resources. While some bioplastics are compostable or biodegradable, many of them are not, therefore despite being formed of natural ingredients, they won’t decompose.
  • Compostable plastic: The phrase “compostable plastic” refers to polymers that need certain circumstances in order to degrade, as opposed to the simpler requirements for biodegradable plastics. 

Compostable plastics often need industrial composting facilities, but biodegradable plastics may decompose in a more natural setting.

How Long Does Biodegradable Plastic Take to Disintegrate?

When exposed to air or sunshine, biodegradable polymers typically take three to six months to break down. Regular plastics may take up to a thousand years to decompose to the same degree.

4 Environmental Benefits of Biodegradable Plastics

Bioplastics, often known as biodegradable plastics, may decompose naturally since they are created from natural plant-based basic ingredients. 

This is accomplished when the plastics are naturally metabolized by the bacteria and fungus present in the immediate environment. 

They also aid in further disassembling a biodegradable plastic structure. These plastic materials, which were developed to address the issue of plastic waste, will decompose over time.

The following list outlines four ways biodegradable plastics are good for the environment and save natural resources.

  • Conserves nonrenewable energy sources
  • Cuts Back on Carbon Emission
  • Utilizes Less Energy
  • Offers an environmentally friendly remedy

I will now elaborate on these.

Conserves nonrenewable energy sources

Plastics made from biomaterials help save petroleum resources. Oil molecules are heated and processed into polymers to create traditional plastics. 

Bioplastics are produced using plants, such as switch grass and maize, as their primary raw materials. This encourages them to preserve non-renewable energy sources like petroleum.

Cuts Back on Carbon Emission

Significantly lower carbon emissions during production are one of the key benefits of utilizing biodegradable plastic. 

Additionally, since biodegradable plastics are made from plant-based ingredients, very little carbon is released during the composting process.

Utilizes Less Energy

Less energy is used for the production of biodegradable polymers. Additionally, they may be reprocessed without using fossil fuels. The pollutants and environmental damage are greatly reduced since less energy is used.

Offers an environmentally friendly remedy

For biodegradable plastics to break down properly, composting or recycling is necessary. Waste is automatically reduced by the obligation to properly discard biodegradable plastic items. 

Otherwise, this garbage would be disposed of by being transported to landfills. Furthermore, rather than being turned into landfills, the land areas might be utilized for industrial, residential, or agricultural purposes.

As you can see, biodegradable plastic is crucial and shown to be highly important when it comes to cutting waste and preserving the environment. 

A greener and more sustainable future for our world is something we may anticipate with the rising usage and production of bioplastics.

What benefits can biodegradable bags offer?

As you can see, utilizing biodegradable bags does not compromise quality, but what other benefits are there? 

The top seven reasons why you should select biodegradable packaging for your company have been compiled from the many advantages of using biodegradable bags.

  • Decreased Carbon Emissions
  • Waste minimization
  • Recycling and reusing
  • Reduction in Pollution
  • Non-Toxic 
  • Less Petroleum
  • Supportive of brand

I will now elaborate on these.

Decreased Carbon Emissions

The distinctive biodegradable substance used by Polystar is constructed of PLA bioplastic. This product’s production method emits far fewer carbon emissions than typical plastic since it is plant-based. 

Biodegradable polymers have a 500% lower carbon footprint than conventional plastic, emitting just 0.8 tonnes instead of four tonnes.

Waste minimization

The UK now produces over 30 million tonnes of residential garbage annually, of which around 35 percent is garden and kitchen waste. 

Biodegradable plastics degrade over time, which results in a significant decrease in the amount of garbage produced and less waste ending up in landfills. 

Less trash means less waste to manage since there is less rubbish taking up space in landfills. conserving the beauty of our earth and saving land for other uses.

Recycling and reusing

Bioplastics are significantly better than conventional plastic kinds in that they include oils that are derived from plants. It is simpler to create novel forms and textures because the oils make the surface of biopolymers more flexible and less brittle.

They may be shaped in various attractive ways to meet your needs and are just as moldable as conventional polymers. Additionally, during their lifespan, they may be recycled and used for other purposes.

In contrast, certain non-biodegradable plastics are unsafe for recycling because they may leak hazardous, poisonous substances after their first usage. 

There are no harmful chemicals or poisons in biodegradable bags & packaging since they are made from organic elements that may be found in nature.

Reduction in Pollution

Biodegradable materials gradually decay and are absorbed by soil and other natural elements as they degrade organically. Less pollution will occur from this natural process since no forced chemical reaction is required to initiate the process.

They are simple to recycle and don’t release harmful substances since they break down faster than conventional plastics.


Because they are comprised of natural materials, biodegradable bags are safer for users.

Traditional plastics are created with hazardous chemicals and byproducts that endanger both the environment and human life. During the disintegration process, they are probably going to release these dangerous compounds. 

In addition, PET, the plastic used to make the majority of conventional water bottles, may draw dangerous microorganisms or potentially leak chemicals.

However, this is not the case with biodegradable plastic, adding weight to the argument in favor of these materials. They are risk-free and don’t produce any poisons when they break down. By the earth, they are absorbed.

Less Petroleum

Additionally, using biodegradable polymers reduces the need for petroleum. Oil molecules are heated and processed to create polymers to create traditional plastic.

Traditional plastic production procedures require up to 2.7% of a nation’s petroleum reserves.

On the other side, natural resources including sugar cane, maize, orange peels, starch, and plants are used to make biodegradable plastics. The energy needed for this process is far lower, and it often doesn’t entail burning fossil fuels.

This translates into a far larger production capacity for biodegradable polymers while using much less energy. Therefore, less pollution is created in addition to the use of fewer valuable resources. 

We can redirect oil resources to other purposes, including heating and transportation, by producing less conventional plastics and more biodegradable plastics in their place.

Supportive of brand

The good impact biodegradable bags may have on your business is another advantage. Due to its reputation for sustainability, big businesses like Coca-Cola use bioplastics in their goods. 

Along with benefiting the environment, choosing greener solutions may enhance your brand.

Biodegradable Plastics Uses

Although there are theoretically numerous applications for conventional plastics that may be replaced by biodegradable polymers, the increased expense of switching keeps many firms from doing so. 

You still come across biodegradable plastics on a regular basis, therefore search for the label that indicates this. Most often, biodegradable polymers are used to create items like:

  • Food packaging: A variety of materials, like cheese byproducts and nut shells, may be used by manufacturers to create biodegradable food packaging. Coffee cups, carryout bags, and takeout containers are examples of typical biodegradable plastic items.
  • Disposable tableware: It’s simple to buy biodegradable plastic dishes, cups, and utensils on the market; some of them feel smoother like ordinary plastic, while others have the texture of paper or cardboard.
  • Plastic bags: A variety of biodegradable plastic bags, such as produce bags, shopping bags, and other single-use bags, are available.
  • Packing peanuts: Biodegradable packing peanuts are now widely available, replacing the old ones that were constructed of non-biodegradable polystyrene.
  • Plant pots: Many businesses now package their plants in biodegradable containers, allowing for direct germination and natural soil decomposition of the material.
  • Medical goods: Many medical products, including surgical sutures & wound dressings, are manufactured from biodegradable materials, so they spontaneously decompose once the patient has recovered without the need for an intrusive procedure to remove the product.

What Issues Arise With Biodegradable Plastic?

Although biodegradable may help in the fight against conventional plastics in the environment, it does have several disadvantages:

  • It may not decompose entirely. While the impacts of biodegradable plastic are still being studied, there is evidence that certain forms do not totally degrade. Biodegradable plastics may be much more detrimental to the environment when they only partly degrade since the tiny fragments (known as microplastics) are more difficult to detect or clean up.
  • When it breaks down, hazardous compounds may be released. Even though less toxic chemicals are released as biodegradable plastic breaks down, certain forms of biodegradable plastic may still emit dangerous materials including metals and methane.

Frequently Asked Questions(FAQs), “Why biodegradable plastic is important?”

Why are environmentally friendly biodegradable polymers preferable?

The use of biodegradable plastics is preferable since they degrade quickly, may be absorbed by the soil, and can even be turned into compost. 

Furthermore, even if a total breakdown does not take place, it is simple to reduce the amount of area needed to get rid of the world’s plastic trash.

Why is biodegradation significant?

Products that are biodegradable degrade substantially more quickly than other product categories. Biodegradable materials decompose into harmless substances including carbon dioxide, water vapor, and organic debris.

What benefits and drawbacks do biodegradable garbage have?

Biodegradable plastics are non-toxic since they include no chemicals or poisons in contrast to other kinds of plastics that may release dangerous compounds, particularly if burnt, and they decompose more quickly when thrown. They can also be recycled.

How do biodegradable plastics affect the environment, and what are they?

If a degradation-promoting ingredient is added to degradable polymers, the plastics might disintegrate into smaller pieces. 

However, depending on the exposure to sunshine and oxygen, the biodegradation of oxo-degradable plastic bags in compost conditions might take many years.

How does the economy benefit from biodegradable plastic?

Utilizing renewable feedstocks, recycling petroleum-based plastics, and lowering the use of scarce resources, growing usage of bioplastics is reducing landfill trash and producing goods that function on par with or better than conventional plastics in many applications.
