Plastic pollution is one of the most pressing environmental challenges today. Plastic bags, bottles, and single-use packaging are ubiquitous in daily life. The emergence of degradable and biodegradable plastics offers a more sustainable path for both industry and society. However, these two types of plastics are often misunderstood as being the same. In this article, Vichem clarifies the differences between degradable and biodegradable plastics to help businesses and consumers make informed choices.
INTRODUCTION TO DEGRADABLE AND BIODEGRADABLE PLASTICS
What Are Degradable Plastics?
Degradable plastics are typically conventional plastics modified with additives to facilitate fragmentation. Their primary composition consists of petroleum-based polymers such as polyethylene (PE), polypropylene (PP), or polystyrene (PS). Under exposure to sunlight and oxygen, these plastics break down into smaller fragments.
While they may appear to “disappear,” this is misleading. Degradable plastics do not fully decompose in natural environments. Instead, they fragment into microplastics, which persist in soil and water for centuries, posing significant risks to ecosystems and human health.
What Are Biodegradable Plastics?
Biodegradable plastics are materials capable of complete biological decomposition. They are typically made from renewable sources such as corn starch, sugarcane, cassava, or organic acids. When degraded, these plastics break down into carbon dioxide, water, and biomass, leaving no microplastics behind.
Biodegradable plastics often comply with international standards like EN 13432 or ASTM D6400, ensuring their environmental safety. Unlike degradable plastics, they decompose harmlessly in a relatively short time frame—ranging from weeks to months, depending on environmental conditions.
KEY DIFFERENCES BETWEEN DEGRADABLE AND BIODEGRADABLE PLASTICS
Despite similar-sounding names, these two types of plastics differ fundamentally. Degradable plastics only fragment into smaller pieces and remain in the environment, while biodegradable plastics undergo chemical transformation, returning to natural substances. This distinction significantly impacts the sustainability of material solutions.
A common source of confusion arises from terms like “bio” or “eco” being misused on product labels. Not all products labeled “eco” are genuinely biodegradable. Businesses and consumers must verify certifications and product information to ensure true biodegradability. Only materials meeting international standards guarantee biological decomposition.
BENEFITS FOR BUSINESSES AND CONSUMERS
Choosing biodegradable plastics offers clear environmental advantages over degradable alternatives. Biodegradable plastics reduce long-term waste accumulation and mitigate microplastic pollution. Businesses adopting these materials are recognized for their social responsibility and can position themselves as leaders in the global green consumption trend.
Transitioning to biodegradable plastics is not only a long-term strategy but also a necessity. Modern consumers increasingly prefer environmentally friendly products, driving demand for bio-based materials. This shift creates significant market opportunities for businesses investing in sustainable solutions.
COMMON APPLICATIONS OF BIODEGRADABLE PLASTICS
Biodegradable plastics are widely used in producing food packaging, compostable waste bags, PLA-coated paper cups, and more. Other applications include agricultural mulch films, medical packaging, and commercial packaging. Their safety and rapid decomposition make them ideal for sensitive industries like food and healthcare, where hygiene standards are paramount.
Unlike conventional degradable plastics, biodegradable plastics leave no residual traces, which is critical for waste management and recycling processes. They can be processed in industrial composting facilities or natural environments, offering high adaptability and making them an effective alternative to traditional plastics.
CONCLUSION
The distinction between degradable and biodegradable plastics is unmistakable. Only biodegradable plastics ensure complete decomposition without contributing to microplastic pollution. To build a greener future, selecting the right materials is essential. Avoid being misled by confusing terminology when making decisions.
