We’re constantly bombarded with terms like “biodegradable” and “compostable.” While both terms suggest eco-friendliness, they don’t necessarily mean the same thing.
Understanding the key differences between biodegradable and compostable bags is crucial for making informed choices and minimizing our environmental impact. This blog post will delve into the specifics of each term, exploring their definitions, breakdown processes, and the implications for our planet.
By the end, you’ll have a clear understanding of which bags are truly sustainable and how to choose the most eco-friendly options for your everyday needs. Let’s dive in and uncover the truth behind these often-misunderstood terms.
What Are Biodegradable Bags
Biodegradable bags are designed to break down naturally over time through the action of microorganisms like bacteria and fungi. This decomposition process transforms the bag into simpler substances such as water, carbon dioxide, and biomass, which can be absorbed back into the environment.
The materials used to create biodegradable bags can vary greatly. Some are made from plant-based materials like corn starch or vegetable oils, while others may be traditional petroleum-based plastics that have been modified with additives to accelerate their breakdown.
What Are Compostable Bags
Compostable bags are a specific type of biodegradable bag that is designed to break down completely into natural elements within a relatively short timeframe. This breakdown occurs in a controlled environment like a commercial composting facility, where specific conditions like temperature, moisture, and oxygen levels are maintained.
These bags are typically made from renewable resources such as plant starches (like corn or potato starch), cellulose, or other bio-based polymers. They are certified to meet specific standards, ensuring they decompose safely and effectively without leaving any harmful residues.
