The fundamental difference lies in the source and composition of the materials used. Traditional plastic bags are typically made from polyethylene, derived from non-renewable resources like petroleum. On the other hand, compostable bags are made from renewable resources like cornstarch, PLA, and PBAT. This distinction is critical because it not only affects the biodegradability of the bags but also their impact on resource depletion and environmental pollution.

Biodegradability and Environmental Impact

When it comes to environmental impact, biodegradability is a game-changer. Traditional plastics can take hundreds to thousands of years to break down, and even then, they fragment into microplastics that continue to pollute the ecosystem. Compostable bags, in contrast, are designed to break down in a compost environment within a much shorter period – typically a few months. This rapid degradation means they contribute significantly less to landfill mass and are less likely to cause long-term environmental damage.

Landfill Space and Marine Pollution

In landfills, traditional plastic bags can occupy space for centuries, contributing to the growing waste management crisis. They are also a significant contributor to marine pollution, harming wildlife and ecosystems. Compostable bags, due to their ability to break down, alleviate some of these pressures on landfills and pose a lesser threat to marine life.
