Plastic pollution is not just about the visible aspects of it anymore.

Yes, we can see plastic bottles floating on the surface of rivers when we look out over them.

We can see carry bags hanging from trees when we walk through parks.

And we often hear the ocean is full of plastic waste.

But microplastic pollution is an even larger and more dangerous issue, and much harder to see.

Microplastics are minuscule plastic pieces—generally less than five millimeters in size—that have been discharged into the soil, into the water supply, into the food chain, and even into our own bodies. One of the greatest sources of microplastic pollution is everyday plastic bags that end up in the environment through unintentional disposal by people living in developed countries.

What can earth-friendly, biodegradable, compostable bags do to help reduce this pollution? Read on to find out how compostable bags can help reduce the microplastic pollution problem and why it’s even more essential for India and around the globe today.

What Are Microplastics and Why Are They Dangerous?

When large pieces of plastic, like shopping bags, are exposed to light, heat, and the elements, they break down into smaller pieces called microplastics. These small pieces do not decompose; they simply become smaller. Therefore, instead of disappearing completely when they break down, they:

• Form smaller microplastics over time.
• Get mixed into the earth.
• Wash into rivers and lakes.
• Flow through groundwater.
• End up on farms.
• Eventually, go into the food chain.
  
  

Once microplastics get out, it is extremely difficult to remove them.

Global research shows that microplastics have been found in various places, including:

• Farms.
• Drinking water.
• Oceans and other waterways.
• Sea salts.
• Fruits and vegetables.
• Human blood samples.
  
  

Microplastics and their health risks have grown beyond an environmental issue and are now a public health issue.

How Traditional Plastic Bags Create Microplastics

The process by which traditional plastic bags create microplastic particles is as follows:

1. Get exposed to sunlight and heat
2. Undergo photo-degradation
3. Fragment into micro-sized particles
4. Mix into the soil layers
5. Get washed into water bodies through rainwater runoff.
   
   

Most microplastic particles in the environment can remain there for hundreds of years.

The long-term impacts of microplastics in the environment include:

• Loss of soil fertility
• Disruption of soil organisms
• Contaminated crops
• Ingestion by marine animals
• Chemical leaching into the groundwater.
  
  

These are all reasons why it is important to find a substitute for traditional plastic bags.

What Makes Compostable Bags Different?

Compostable bags are designed to break down to natural products only under ideal composting conditions.

Composting is a natural process and will take time to occur. However, once composting takes place, compostable bags will decompose into water, carbon dioxide, and biomass. Compostable bags do not break down into microplastics.

There are some advantages of compostable bags compared with traditional plastic:

• Will not fragment into microplastics
• Decompose into water, carbon dioxide, and biomass
• Will not leave toxic residue
• Will support soil health
  
  

Compostable bags are made from plant-based materials:

• Corn starch
• PLA (Polylactic acid)
• compostable polymers blends.
  
  

At Dr. Earth, we designed our biodegradable and compostable bags to break down completely and not leave behind any harmful plastic remains.

The greatest difference is that plastics fragment, compostable materials do not.

How Compostable Bags Prevent Microplastic Formation

Let’s break this down simply with a scientific explanation.

1. Complete Biological Breakdown

Compostable bags are made to decompose completely by the action of organisms such as bacteria and fungi present in a composting environment. When compostable bags decompose, they do not generate smaller pieces of persistent plastic as they:

• Are eaten by microbes
• Converted into natural organic matter
• Became incorporated into the compost.
  
  

The biological breakdown prevents the generation of long-lasting microplastics.

2. No Synthetic Polymer Residue

Conventional plastics use synthetic polymers made from petroleum, which takes millions of years to naturally decompose. Conversely, compostable bags use natural, biodegradable materials that decompose completely under appropriate environmental conditions. In carefully controlled studies, compostable bags are tested to ensure that, after decomposing, they:

• Do not produce any visible plastic remains
• Do not leave any toxic residues present
• Do not degrade soil quality
  
  

Therefore, compostable material contributes to soil quality as well as groundwater systems.

3. Reduced Soil Contamination

Microplastics contaminate soil in many different ways such as:

• Blocking the opportunity for water to be absorbed
• Interfering with the growth of plants’ roots
• Harming beneficial organisms such as earthworms and other organisms
• Reducing crops from growing causing food shortages.
  
  

If compostable bags are properly composted, they will enhance the soil and not contaminate it. For example, for farming to succeed over a long-time period, it is imperative to minimize soil contamination.

Compostable bags improve agricultural productivity and food security, especially within agricultural societies, such as in India.

4. Protection of Water Bodies

Plastic bags often end up in:

• Drains
• Rivers
• Lakes
• Coastal regions
  
  

Microplastics enter the water system as they break down into smaller and smaller pieces. Fish and other marine species consume the microplastics by mistake. This disrupts the foodchain of aquatic ecosystems, and ultimately impacts human consumers.

Compostable bags help to alleviate this problem by preventing the persistent plastic foundation that generates microplastics from being in the ocean.

Since compostable materials decompose with proper disposal, there will not be any long-lasting plastic impact on the ocean.

The Indian Context: Why This Matters Now

India produces a lot of plastic waste (millions of tons) each year; a large volume of it is dumped into open landfills and disposed of in natural water bodies or agricultural areas.

As a result of rapid urbanization and increased consumption patterns, if conventional plastics remain the dominant form of packaging, we’ll continue to see an increase in the number of microplastics in our environment.

Soil in India is already under immense strain due to:

• Chemical fertilisers
• Industrial by-products
• Urban runoff
  
  

Microplastics add to this amidst other stresses, further reducing crop yields.

Replacing plastic with compostable bags is not limited to finding alternatives — it is about ensuring the overall health of soil and water for future generations.

Supporting a Circular System Instead of a Fragmented One

The lifecycle of plastic involves a fragmented process.

• Production → Use → Dispersing → Microplastic Pollution → Damaging the Environment
• Compostable bags have a circular process of life (production, Use, Compost, enrich the soil, and restore the World).
• Using a circular system stops the slow accumulation of microplastic particles within the environment.

Many people have questions about compostable bags:

Addressing Common Concerns

Do compostable bags break down everywhere?

Compostable bags will break down 100% in industrial facilities. When supplied with adequate conditions of heat, humidity, and oxygen, they break down without leaving behind plastic.

Are compostable bags strong enough?

Yes. The new development of composition technology has produced a product that has an equivalent strength and durability to a traditional plastic bag, while not being harmful to the environment.

What if compostable bags end up in landfills?

The most eco-friendly choice for a compostable bag is if it is composted; however, even if a compostable bag ends up in a landfill, it would yield fewer long-lasting microplastics than a traditional bag. (It will be worth as much as you invest in proper segregation of waste and compost infrastructure.

Why Responsible Manufacturing Matters

Not every product claiming to be environmentally safe is truly making an effort to stop microplastics from reaching their final resting place (the ocean).

Inferior manufacturing materials can:

• Only partially decompose (breakdown)
• Leave behind residues from synthetic materials
• Confuse consumers as to whether they are buying a quality product
  
  

A certified compostable bag is tested and approved to ensure that it will completely break down into natural materials without creating any microplastics.

At Dr. Earth, we manufacture high-quality biodegradable and compostable bags that meet environmental regulations and sustainability objectives. In order for there to be a reduction in microplastic levels made through eco-friendly marketing claims, science-based solutions must support the claims.

The Bigger Picture: Protecting Future Generations

Microplastic pollution is not visible at present, but will be irreversible in the future. If we continue our dependence on traditional plastic bags, the continual accumulation of microplastics in soil and water will take place each year.

That means:

• An increase in contaminated crops
• An increase in polluted rivers
• An increase in health risks
• An increase in costs for cleanup
  
  

Changing to compostable bags is a very simple but powerful choice that will:

It helps:

• Protect the fertility of the soil
• Protect the quality of our groundwater
• Protect the marine ecosystem
• Reduce long-term environmental impacts
  
  

Many individuals and businesses make small daily decisions that can provide an even greater cumulative impact than any large decision could ever achieve.

Final Thoughts

plastic waste is not only found on the surface of the land and in our oceans, but also has a terrible impact at a microscopic level — all these plastic bags break down into microscopic pieces of plastic over hundreds of years or more (called microplastics).

Compostable bags are made to be completely returned back to the Earth, while still being safe for the Earth, after they are used.

Since India relies significantly on having a healthy soil and clean water, the choice to use compostable packaging should not only be made to help our planet but should also be seen as an investment in the future of our ecosystem.

At Dr. Earth, we are committed to producing biodegradable and compostable bags that help reduce microplastic pollution and protect our soil and water resources.

Because true sustainability is not about what we see.
It is about protecting what we cannot see — before it is too late.
