There is a reason why plastic waste is so abundant – plastic solves our day-to-day problems, making daily tasks easier. But at what cost!
Trying to find alternatives for plastic can be challenging and frustrating. Plastic zip lock bags, for example, make it easy to put things away, pack lunches, and preserve cheese! Why not take a step to a more sustainable lifestyle and replace plastic zip lock bags with compostable zip lock bags? Same functionality and better for the planet!
Made from renewable resources like cornstarch or sugarcane, compostable zip lock bags biodegrade in composting environments, reducing dependence on non-renewable fossil fuels and lowering their carbon footprint. The production of compostable bags is generally more sustainable, and their use contributes to a decrease in pollution and harm to wildlife associated with persistent plastic waste. With a growing consumer demand for sustainability, choosing compostable zip-lock bags aligns with eco-friendly preferences and supports a more environmentally conscious approach to waste management.
Here are the 5 best compostable zip lock bags that we recommend.
