Understanding Biodegradable Plastic
Bio means life.
Biodegrade means - the concept of the manufacturer of degradable plastics and polymers was in 1980. These biodegradable plastic bags are capable of being decomposed by bacteria and other living organisms.
A quick note:
Bioplastics are made out of natural products like wheat corn. Bioplastics are made from traditional petrochemicals, which break down quickly.
Bioplastic bags are made from substances to which microbes can quickly ingest.
Let’s understand what biodegradable plastic is.
PLA (polylactic acid) is made out of sugars, corn starch, cassava, or sugarcane. It is biodegradable, carbon-neutral, and edible. To transform corn into plastic, corn kernels are immersed in sulfur dioxide and hot water, where this raw material breaks down into starch, protein, and fiber to attain the bioplastic.
These bags take three to six months to decompose completely, much quicker than synthetic bags that take thousands of years.
Biodegradable plastic is one of the products made from petrochemicals. These particular kinds of plastic are made so that they can easily breakdown in the presence of water and air.
Here is why you should use biodegrading plastic bags
Bio degrading bags are eco-friendly and are 542 able to break down much more quickly than traditional plastic bags.
Biodegradable plastic bags can be recycled.
These plastic types take less time to decompose when disposed of but can easily be recycled through an organic process. They are also non-toxic is they have no harmful or chemicals in their manufacturing process.
Energy consumption is less.
The manufacture of these plastic bags is indeed costly. In the end, it's worth it if the clean-up cost is considered. Biodegradable plastics will turn out to be a smart choice.
Biodegradable plastic bags are thrown. Their presence in the soil will make them fertile. The ingredients decay and improve the soil water and nutrient retention and help the plant grow without pesticides or chemical fertilizer.
Reduction of carbon dioxide levels
With biodegradable plastics, some of those made from sugar and carbon dioxide, researchers from the University of Bath, the world foretell a future of plastics that can decompose and release only the amount of energy used to make it.
Biodegradable bags do not release harmful chemicals when disposed of.
Since they are made from natural substances, when disposed of will only release natural substance unlike the traditional plastic bags when disposed release methane which is harmful to the plants.
Are biodegradable bags good for me to line my bins with?
The most eco-friendly solution is in doubt to not line your bin with a bag; you can decide not to use a liner? You can achieve this by separating your compostables, recyclables, and general waste, composting and recycling as much as you can. By doing this, you may notice you’re sending less waste to landfills as a result. And suppose you still prefer a bag to line your general waste bin with a plastic bag. In that case, the best option is to choose a certified biodegradable or certified compostable bag instead of traditional plastic bags or those labeled degradable.
Comparison of traditional plastic bags and the degradable plastic
When biodegradable plastic bags are acted upon by fungi and bacteria, they are friendly to the environment because they are made out of plant-based material. These bags take a period of three to six months to decompose fully.
Traditional plastic bags are made out of polyethylene, which consists of a long chain of monomers. These are non-renewable resources and are a rise to harm both the land and marine. When thrown to the ground, these plastic bags do not decompose, leading to both soil infertility and the death of both plant and water inhabitants.
