Biodegradable plastics break down faster in soil
Biodegradable plastics rapidly decompose in soil through microbial action, offering a sustainable solution to the centuries-long persistence of traditional plastics and reducing environmental pollution.
Biodegradable plastics decompose much quicker in soil than traditional plastics. While fossil fuel-based plastics can linger for hundreds to thousands of years, creating lasting pollution, biodegradable alternatives, often from cornstarch or sugarcane, use soil microbes to break down into harmless elements like water and CO2. For example, PLA plastic can degrade in soil within six months to two years under ideal conditions, a stark contrast to the 450 years a plastic bottle might take. This rapid breakdown significantly reduces microplastic accumulation and helps tackle the 300 million tons of plastic produced annually.
