PLA (polylactic acid) is made from renewable raw materials which is 100 % biodegradable and compostable. It has a reduced carbon footprint compared to fossil based plastics.
In the wild, light, rain, temperature, moisture, PH value are all important element for degradation, it will take about 1 year to degrade completely in normal nature environment; in landfill environment, the synergy of temperature, moisture, microbes, PH value will reduce the degradation time, it will take about 3 to 6 months.
