3. Biodegradable Plastics
Why in News?
- As people are searching for alternatives to plastics, many are trying out a new version known as biodegradable plastic. The question arises, whether it is as safe as presumed.
- Plastic, in the form of bottles, bags, packaging materials, furniture and more, has become an integral part of our present-day lives. However, there are rising problems due to over-use of plastic which has caused a worldwide alarm.
- Theoretically speaking, biodegradable means the material should break down into water, carbon dioxide and minerals. However, this is not the case with all plastics.
- Also, many of the plastics that are bio-degradable, only degrade at very specific temperatures and also need optimal levels of light, water and oxygen for the same.
- And even then, they leave behind residues which are toxic for the environment. Many of the plastics will not Biodegrade Naturally.
- Owing to the conditions required for their biodegradation, a lot of plastics will only get biodegraded at industrial facilities.
- Many Bio-based plastics are known to not be biodegradable. However, they can be recycled, albeit partially. They have known to have similar structure to that of fossil fuel-based plastics.
- Every bio-based plastic does not deliver the same amount of pure recycle streams. These streams are the amount of product that can be recycled to produce something new.
- Bio-based plastic and even biodegradable plastic while having their virtues, also come with their own set of flaws. As such, they cannot really be substitutes to plastic due to a lot of reasons.
