The Truth About “Biodegradable” Labels in India
The Problem with “Biodegradable” on Product Labels
Walk into any shop in Kochi or browse an e-commerce platform today, and you will see the word “biodegradable” plastered across countless products — from carry bags to takeaway containers. For small business owners and MSMEs across Kerala, choosing eco-friendly packaging is no longer just an ethical decision; it is often a regulatory requirement. But how much of what is labelled “biodegradable” actually breaks down as promised?
The truth is more complicated than the label suggests. In India, the term “biodegradable” has become a marketing buzzword, applied loosely to products that may or may not meet genuine environmental standards. For a business owner trying to make responsible packaging choices, understanding what lies behind these labels is essential — both for the planet and for compliance with Indian regulations.
What Does “Biodegradable” Actually Mean?
At its core, a biodegradable material is one that can be broken down by microorganisms — bacteria, fungi, and other natural agents — into water, carbon dioxide, and biomass. In theory, this sounds straightforward. In practice, the conditions required for biodegradation vary enormously depending on the material and the environment.
Some materials biodegrade within weeks in a home compost pile. Others require industrial composting facilities that maintain specific temperatures, humidity levels, and microbial activity. And some so-called biodegradable plastics will only break down under very narrow laboratory conditions that are rarely found in nature or even in most Indian waste processing facilities.
Certified Biodegradable vs. Oxo-Degradable
A critical distinction that every Kerala business should understand is the difference between genuinely certified biodegradable products and oxo-degradable plastics.
- Certified biodegradable — Products tested and certified to international standards such as ASTM D6400 or IS/ISO 17088. These materials fully biodegrade within a specified time frame in industrial composting conditions.
- Oxo-degradable — Conventional plastics with additives that cause them to fragment into small pieces. They do not fully biodegrade; instead, they create microplastics that persist in the environment. The Indian government has moved to ban these products.
- Home-compostable — Materials certified to biodegrade in ambient temperature conditions (typically to EN 13432 or similar standards). These are more suitable for Kerala’s waste management reality, where centralised industrial composting is still limited.
The Indian Regulatory Landscape
India’s approach to biodegradable labelling has evolved rapidly in recent years. The Plastic Waste Management Rules, 2024, brought significant changes that directly affect manufacturers, distributors, and users of plastic packaging in Kerala.
Key Regulations to Know
- Ban on oxo-degradable plastics — The manufacture, import, stocking, and distribution of oxo-degradable plastics have been prohibited across India.
- Compostable plastic requirements — Only plastics certified as compostable under IS/ISO 17088:2021 are permitted for use as carry bags and packaging.
- CPCB certification — Manufacturers must obtain certification from the Central Pollution Control Board (CPCB) for compostable plastic products.
- Labelling standards — All compostable plastic products must display the certification mark, serial number, and manufacturer details on the product or packaging.
For MSMEs in Kochi, Thiruvananthapuram, and other Kerala cities, compliance with these rules is not optional. Local municipal authorities have begun inspections, and businesses found using non-compliant packaging face penalties.
How to Verify a Truly Biodegradable Product
As a business owner, you do not need to be a materials scientist to verify whether a packaging product is genuinely biodegradable. Here is a practical checklist you can use when sourcing bags and packaging materials.
Check for Certification Marks
Look for the CPCB compostable certification mark and the certification number on the product. Genuine compostable bags carry a clear imprint that includes the manufacturer’s registration number and the standard reference (IS/ISO 17088).
Ask for Test Reports
Reputable manufacturers will provide third-party test reports confirming that their products meet biodegradation standards. Ask your supplier for documentation before placing bulk orders.
Distinguish Thickness from Degradability
A thick plastic bag is not necessarily biodegradable. Some businesses assume that thicker gauge means more eco-friendly, but thickness has nothing to do with biodegradability. Always verify certification independently of the product’s physical properties.
Beware of Vague Claims
Terms like “eco-friendly,” “green,” “earth-safe,” and “natural” without a certification standard are marketing claims, not scientific guarantees. Insist on seeing the specific standard reference.
What This Means for Kerala Businesses
Kerala has been at the forefront of environmental regulation in India. The state’s Malabar region and cities like Kochi have seen growing awareness around plastic waste, and consumers increasingly expect businesses to use genuinely sustainable packaging.
For retailers, restaurants, and e-commerce businesses in Kerala, choosing truly biodegradable packaging is both a compliance requirement and a competitive advantage. Customers can tell the difference between a business that has carefully selected certified packaging and one that simply puts a “green” label on conventional plastic.
However, the lack of widespread industrial composting infrastructure in Kerala means that even certified compostable bags may not break down if they end up in a landfill instead of a composting facility. This is an important limitation to understand — biodegradability is only meaningful when the product reaches the right environment.
Making the Right Choice for Your Business
Navigating the world of biodegradable labels can feel overwhelming, but the fundamentals are simple: look for certification, ask for documentation, and choose suppliers who are transparent about their standards. For most MSMEs in Kerala, bio-degradable polymer bags from reputable manufacturers offer a reliable path forward.
