Why Are Composable Plastic Kitchen Bags Considered Better for the Environment?

Composable plastic kitchen bags are considered better for the environment because they break down more easily and leave behind less harmful waste than traditional plastic bags. These bags are designed to decompose into natural materials, reducing their impact on landfills and ecosystems.

The definition of composable plastics comes from the American Society for Testing and Materials (ASTM), which categorizes them as materials that can decompose under specific environmental conditions into carbon dioxide, water, and biomass within a designated timeframe.

Several factors contribute to the environmental benefits of composable plastic bags. First, they are made from renewable resources, such as corn starch or other plant materials. Second, their degradation process is expedited under certain conditions, such as heat, moisture, and microbial activity. This contrasts with conventional plastics that can take hundreds of years to break down.

Key technical terms include “biodegradable” and “compostable.” Biodegradable refers to substances that can be broken down by microorganisms into natural substances. Compostable, however, indicates that a material can biodegrade under composting conditions, creating nutrient-rich compost for soil.

The decomposition process involves microorganisms consuming the organic material in composable bags. These microorganisms, such as bacteria or fungi, thrive in moist environments. They break down the bag, converting it into carbon dioxide, water, and biomass. This process can occur within a few months to a couple of years, depending on the conditions.

Specific conditions that enhance the decomposition of composable kitchen bags include exposure to sunlight, moisture, and a warm environment. For example, placing these bags in a compost pile with food scraps and garden waste provides an optimal environment for degradation. In contrast, traditional plastic bags remain intact in similar conditions, contributing to pollution and environmental degradation.
