Benefits of Using Biodegradable Plastics

Studies have revealed that Americans are generating plastics more than ever, and a negligible amount of plastic is sent for recycling. At least 85% of the 40 million tons of municipal plastic waste anticipated to be produced in the U.S. in 2021 was dumped there, according to Statista. In spite of the U.S. producing more plastic debris than ever before, recycling rates are declining. Plastics and its by-products are cluttering up our cities, oceans and contributing to deadly health problems in humans and animals.

Thankfully, biodegradable plastic is an effective solution to mitigate the world-wide epidemic of non-biodegradable plastic bags and provide feasible alternatives to improve the environment and save marine species. Therefore, we can gain many benefits of using biodegradable plastics to save the future.

Biodegradable plastics have ignited a revolt against ubiquitous plastic bags and by using them one can effectively contribute in conserving non-renewable resources of Earth that are depleting at a high-speed. Knowing the advantages of the options can help you address the plastic issue. Let’s check this out!

Why Are Bioplastics Created?

There are many benefits of using biodegradable plastics. Suppose you are thinking to change your petroleum based plastics to bioplastics, the following points will give you better understanding:

  • Bioplastics are renewable; biodegradable materials. Their use is expanding, and they provide a great substitute for reducing the issue of environmental plastic waste. In fact, within 10 years, it is anticipated that this product would meet the demands of 10% of the European plastics industry.
  • Some claim that bioplastics, which contain 20% or more renewable resources, could be the answer to the problem of plastic pollution. Meanwhile, raw ingredients derived from petroleum are used to make traditional plastic. Therefore, bioplastic can reduce reliance on fossil fuel supplies, creating a smaller carbon impact, and quicker decomposition.

What is Biodegradable Plastic?

Biodegradable plastic is a type of plastic that is intended to disintegrate when it comes into contact with microbes. It is typically derived from natural byproducts and is manufactured under strict temperature and humidity controls. The term of biodegradable plastic refers to the plastic that is made from natural plant-based raw materials like corn-starch, sugarcane bagasse, orange peels, starch etc.

Moreover, biodegradable plastic decomposes naturally in the environment when microorganisms metabolize and break down the structure. The end-products of bio plastic also cause less harm to the environment as compared to the traditional plastic.

1. Biodegradable Plastic Meaning

Generally, biodegradable plastic means plastics that can be broken down into water, carbon dioxide, and biomass by living things, typically microbes. Biodegradable plastics are frequently made from petrochemicals, microorganisms, renewable raw materials, or mixtures of all three.

In addition, natural byproducts are typically used to manufacture biodegradable plastic. Bioplastics degrade under well regulated conditions of temperature and humidity in industrial settings.

2. How is Bioplastic Different From Normal Plastic?

Conventional plastics, like fossil-fuel plastics come from natural gas or petroleum. On the other hand, the term “bioplastics” refers to polymers made from renewable biomass sources, such as plant lipids and oils, corn starch, straw, woodchips, and recovered food waste, among others.

Due to the raw materials and certain making process, bioplastic has a slightly higher price than fossil fuel plastic. For instance, the cost of PET or PE made from sugar cane or bio-ethanol is around 20% higher than that of traditional plastics. 

However, bioplastic is still the better alternative to normal plastic. In terms of the impact to the environment, bioplastic has a better performance. In fact, the creation of bioplastics results in fewer greenhouse gas emissions compared to conventional plastic. In addition, bioplastic will break down after 3-6 months, while fossil fuel plastic takes years to fully degrade.

3. How Long Does Biodegradable Plastic Last?

Biodegradable plastic bags need a few months to a few years to completely decompose, depending on the environment that is populated by microbes to speed up the process. On the other hand, conventional plastic bags take hundreds of years to completely degrade.

Similar to conventional plastics, bioplastics would disintegrate into tiny fragments if they were to end up in the ocean. In contrast to conventional plastic, which can take hundreds of years to completely degrade, biodegradable plastics need only three to six months to do so, according to BBC Science Focus.

4. How Effective is It To Use Biodegradable Plastic?

The use of biodegradable plastics is preferable because 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 waste. Therefore, there is a good impact of using biodegradable plastic in future.

Moreover, biodegradable plastic production produces lower carbon emission. Because the plants that produce bioplastics absorb the same amount of carbon dioxide as they grew, there is no net increase in carbon dioxide as they decompose. After all, using biodegradable plastic is an effective way to protect the environment.

5. How Will Biodegradable Plastics Change The Future for The Better?

Biodegradable plastics consume less fossil fuels, produce less carbon dioxide, and degrade less harmfully. In addition, bioplastics are less harmful and don’t include Bisphenol A (BPA), a hormone disruptor that is frequently present in conventional plastics. As the demand for biodegradable plastics increases, they will contribute to save our planet.

According to a business analysis from MarketsandMarkets, the market for biodegradable plastics is anticipated to reach $6.12 billion by 2023.

Advantages of Using Biodegradable Plastics

When it comes to a simple step you can take to save the Earth, changing your conventional plastic to bioplastic is the right choice. Besides, there are many benefits using biodegradable plastics. To help you fully understand, here are some advantages when you decide to use bioplastics.

1. Reduction in Carbon Emission

The formation of traditional plastic involves use of carbon in an excessive amount. This carbon is released into the atmosphere when the used plastic begins to decompose or melt. There are positives that methane and other pollutants could also be released when traditional plastic is recycled or burned.

In contrast, biodegradable plastics do not release carbon or methane as no carbon is used in its manufacturing process. Biodegradable plastics are broken down by naturally-occurring bacteria and since these plastics are plant-based, a minimal amount of carbon is released during the composting process.

2. Lesser Energy Consumption

Though the initial investment in the biodegradable plastics might be slightly higher, in the long run biodegradable plastics involve a lesser amount of energy in its manufacturing process and do not need fossil fuels to be recycled. Thus, it contributes to conserving petroleum supplies.

Conversely, traditional plastic comes from heating and treating oil molecules until they turn into polymers and demands more energy in its production and burning of fossil fuel.

3. Environmentally Friendly Disposable Solution

The traditional plastics are thrown on the scrapheap at landfills. As a consequence, the land that could have been used for agriculture, residence or industrial applications is converted into landfills by non-biodegradable plastic. The usage of biodegradable plastic products will reduce the number of landfills as these products undergo biodegradation when buried or given to composting. The microorganisms in soil will break down the plastic pieces into compost, humus, and other useful compounds.

However, these bacteria will turn up their nose at traditional plastic. Yes, you can try loading their dinner plates with plastic bottles or bags, and you shall see the entire meal being skipped by these unicellular gluttons.

4. Recyclable Material

Biodegradable plastics not only take significantly less time to break down, but can also be recycled to manufacture more plastic by-products. The products produced are non-toxic as they don’t contain chemicals or toxins if compared to traditional plastic.

Use of ground-breaking technology in recycling the bioplastic has closed the loop by creating the materials that lessen our reliance on traditional plastics. The recycled materials are compatible with standard plastic manufacturing equipment, thus making a way for rapid market adoption.

How Safe is Biodegradable Plastic?

Bioplastics are not as toxic as other plastics. However, there are some notes you need to consider regarding its safety. Here are some points you should know to get a better view about the safety of biodegradable plastics:

  • If we’re talking about the “bio” ingredients that can decompose faster than conventional plastic, these materials are safe for the environment. However, some bioplastics are not fully using natural ingredients. In fact, they still mix between the renewable and non-renewable resources. So, the non-renewable material still can harm the environment.
  • Additionally, they contaminate other plastic recycling processes and end up producing microplastics. Therefore, bioplastics still need special disposal treatment to minimize the harmful effect.

How Does Bioplastic Help The Economy?

Bioplastics will be a significant part of the economy. As the green lifestyle becomes more popular, the demand for bioplastics will increase. There will be a shift from a linear economy to a circular economy if plastics industries want to grow without producing toxic waste or having a detrimental impact on the environment.

The design of the circular economy mimics the living environment itself and is restorative and regenerative. Natural materials break down into their fundamental components and are then reused to create new things. Similar to bioplastic production, these renewable material-based plastics are recyclable and compostable.

According to TheBalanceMoney, each year, plastic pollution causes marine ecosystems to suffer economic losses of $13 billion. This includes financial losses to the fishing and tourism sectors as well as expenses for beach cleanup. If we can replace the normal plastic with bioplastic, then we can minimize the negative impact of plastic pollution.

Final Thought

Bioplastics are considered to be more eco-friendly than traditional plastics. Over the course of their lifetime, bioplastics do emit much fewer greenhouse gasses than conventional plastics. In the end, the benefits of using biodegradable plastic that are explained before is definitely promising in the long term, saving our planet and future generations!

When it comes to a better solution to save the planet, bioplastics are definitely better than the conventional one. They reduce use of fossil fuel resources, producing a smaller carbon footprint. Since they are made from natural ingredients, they can break down faster than petroleum based plastics.

When did we start using biodegradable plastics?

The creation of bioplastics was prompted by the 1970s’ rising oil prices and reliance on oil. In 1975, a group of Japanese researchers identified the basic idea behind biodegradable plastics. They found a bacteria called Flavobacterium in pools containing waste water from a nylon mill that degraded nylon.

How can biodegradable plastic be improved?

Since the disposal method has become an issue, we should improve bioplastic by increasing its biodegradability. It is possible to boost the biodegradability of plastics by adding specific microbial strains, a process known as bioaugmentation. Plastics that are already compostable, such poly lactic acid, have had their rate of decomposition accelerated through the use of bioaugmentation.
