Are Compostable Green Produce Bags Really Compostable?

As consumers become more environmentally conscious, compostable green produce bags have become increasingly popular. However, recent research has raised questions about the actual compostability of these bags.

Are green produce bags compostable

Compostable green produce bags are made from plant-based materials, such as corn starch, and are marketed as a more sustainable alternative to traditional plastic bags. The idea is that these bags will break down in a compost pile, leaving no harmful residue behind.

However, a study by the University of Plymouth in the UK found that these bags can take years, if not decades, to fully break down in a home composting system. The study tested four different types of compostable bags, including those made from corn starch, and found that they all remained largely intact after three years.

The problem lies in the fact that home composting systems simply do not get hot enough to fully break down these compostable produce bags. In order for compostable materials to break down properly, they need to be exposed to temperatures of at least 60°C for several weeks. Most home composting systems, however, only reach temperatures of around 30°C.

This means that compostable green produce bags are not actually compostable in the way that consumers may expect. Instead, they are better suited for industrial composting facilities, which can reach the high temperatures needed to break them down.

While compostable green produce bags may not be as environmentally friendly as initially thought, they are still a better option than traditional plastic bags. Biodegradable produce bags wholesale are made from renewable resources and do not release harmful chemicals into the environment. However, consumers should be aware of their limitations and make sure to dispose of them properly.

In general, while eco-friendly compostable green produce bags are marketed as a more sustainable alternative to traditional plastic bags and they are a better option than traditional plastic bags, they are better suited for industrial composting facilities rather than home composting systems. Consumers should be aware of their limitations and make sure to dispose of them properly.
