In a world striving for greener solutions, the word "compostable" is everywhere. But what does it actually mean? And how is it different from "biodegradable"?
Definition
A compostable material breaks down into natural elements withon a composting environment, leaving no toxic residue. This process is driven by microorganisms like bacteria and fungi under controlled temperature and humidity.
Certified compostable products meet strict standards such as ASTM D6400 or EN 13432.
Compostable vs. Biodegradable
Biodegradable: Anything that can break down over time. But this process can take years and may leave harmful microplastics.
Compostable: Designed to transform quickly and safely into nutrient-rich compost, improving soil health and reducing landfill waste.
Why Compostability Matters
Waste Reduction: Compostable packaging diverts organic waste from landfills, reducing methane emissions.
Soil Health: Compost enriches soil, reduces reliance on synthetic fertilizers, and promotes sustainable agriculture.
Circular Economy: Compostable materials close the loop by returning nutrients to the earth, creating a regenerative cycle instead of a wasteful one.
The Reality Check
Research shows challenges: The Big Compost Experiment found that 60% of plastics labeled "home compostable" did not fully disintegrate under real home composting conditions. This highights the need for proper infrastructure and clear labeling.
What can you do?
Look for certifications: BPI, ASTM D6400, EN 13432
Dispose correctly: Compostable products need the right facilities
Educate customers: Clear labeling and instructions prevent contamination and maximize environmental benefits
