NEET BIOLOGY

Detailed explanation-1: -The problem: Ordinary plastic bags are made from oil, which few microbes can digest. So these plastics don’t decay easily. Biodegradable plastics are sometimes made from materials that microbes do readily digest. Others may be held together with chemical bonds that break apart when exposed to water or sunlight.

Detailed explanation-2: -It takes 1, 000 years for a plastic bag to degrade in a landfill. Unfortunately, the bags don’t break down completely but instead photo-degrade, becoming microplastics that absorb toxins and continue to pollute the environment.

Detailed explanation-3: -Plastic bags are non biodegradable.

Detailed explanation-4: -Degradable bags should only be used for and placed into your general waste bin. Like degradable bags, biodegradable are often still plastic bags that have microorganisms added to break down the plastic. Compostable bags are made of natural plant starch, and do not produce any toxic material.
