What is PFA Good for?
January 24, 2025Plastic waste is a pressing issue for our planet. With millions of tons of plastic ending up in landfills and oceans every year, questions about biodegradability are crucial. Among the many types of plastics, Polyoxymethylene (POM) has become a topic of interest. But is POM plastic biodegradable? Let’s explore the facts.
The Growing Concern Over Plastic Waste
Plastic pollution affects our environment, wildlife, and even human health. Traditional plastics can take hundreds of years to decompose, leading to accumulation. Citizens around the world are pushing for better waste management and the creation of sustainable materials.

What is POM Plastic and Where is it Used?
POM, also known as acetal, is a high-performance engineering plastic. It is often used in:
- Automotive parts
- Industrial applications
- Consumer electronics
- Household items
Its strength, durability, and chemical resistance make it a popular choice for various applications.
Decoding Biodegradability: Key Definitions
Biodegradability refers to the ability of materials to break down naturally by microorganisms. Understanding this concept is essential when discussing plastics and their environmental impact.
The Science Behind POM’s Composition
Polymer Structure and Degradation Pathways
POM is made from a polymer structure that consists of repeating units of formaldehyde. This resistant structure makes it challenging for natural microorganisms to break it down.
Factors Affecting Biodegradation Rates
Several aspects affect the biodegradation of plastics:
- Temperature: Warmer conditions can speed up breakdown.
- Moisture: Wet environments may facilitate microbial action.
- Oxygen levels: More oxygen can enhance the degradation process.
Comparing POM to Other Plastics
Compared to biodegradables like PLA or PHA, POM is less environmentally friendly. While other plastics can decompose in months, POM can persist for years.
POM Plastic and the Environment
Persistence in Landfills: Statistics and Studies
POM plastic tends to accumulate in landfills, where breakdown is minimal. Studies indicate that up to 91% of plastics never fully degrade, leading to long-lasting environmental issues.
Impact on Marine Ecosystems: Real-World Examples
POM can enter oceans through waste. Once in marine environments, it poses risks to wildlife. Sea turtles and fish may ingest small pieces, leading to health impacts.
Microplastic Pollution and POM’s Role
POM can break into smaller particles, contributing to microplastic pollution. These tiny bits can enter the food chain, affecting not just marine life but also humans.
