Yes! PLA undergoes a two-step degradation process during composting. The first step is disintegration, where moisture and heat in the compost pile break down the polymer chains, resulting in smaller polymers and lactic acid. The second step is biodegradation, where microorganisms in compost and soil consume the smaller polymer fragments and lactic acid as nutrients. This process is temperature and humidity dependent and ultimately leads to the production of carbon dioxide, water, and humus, which is a valuable soil nutrient.
