What are Green Plastics &Their Environmental Benefits?
The awareness and concern over Earth’s environmental degradation are rapidly increasing around the globe. As a result, an increasing number of businesses and innovators are focusingon environmentally sustainable alternatives. One such alternative that has come up is called ‘Green Plastic’.
Plastics can be found everywhere around you. Most of these plastics (hydrocarbon plastics) are traditionally made from nonrenewable oil-based products.Green plastics, on the other hand, are biodegradable plastics usually made from plant-based polymers.
To put it simply, green plastics or bioplastics are plastic materials that are either:
These plastics are becoming increasingly popular as they can reduce greenhouse gas emissions, dependency on fossil fuels, and landfill volumes. These plastics are still in their infancy, but they have the potential for incredible growth. Green plastics can be used for a wide range of applications, including theproduction of disposable and durable goods.
Some of the most commonly used bioplastics are:
This part bio-based plastic is also known as bio-PET. It is made from bioethanol from sugar cane and is the leading drop-in bioplastic. The best part about this polymer is that it can replace its petrochemical counterpart. Bio-PET comprises 30-35% percent biomass on average.
Polyethylene (PE) and Polypropylene (PP)
The bio-based versions of PE and PP comprise 100% biomass, non-biodegradablepolyolefins based on bioethanol. They’re the second most popular bioplastics. These can be used to include rigid containers, barrier coatings, lidding, film wraps, and othersimilar products.
Polylactic Acid (PLA)
PLA comprises 100% biomass and is a biodegradable plastic. It can be manufactured using the most conventional polymer processing methods. It is strong but brittle and is used to make rigid containers, barrier coatings, and films.
There are numerous other green plastics like Polyhydroxy Alkanoates (PHAs), Cellulose Acetate (CA), and Polyamide (PA) that are being developed and implemented in various industries.
As the name suggests, green plastics are better for the environment. This is mainly because they reduce fossil fuel depletion and greenhouse gas emissions. The environmental impact of green polymers is considerably lower than their petroleum-based counterparts. For example, Coca-Cola’s initial studies show that bottles with 30% bio-PET reduce carbon emissions by 20%.
Biodegradable green plastics help in reducing the waste that occupies landfills. There are systems in place to capture and compost the plastic and produce useful products through the process. Composting can also save money that municipalities and companies have to spend as landfill costs.
Many consumers are now looking at ways they can help the environment. As a result, brands that use green plastics will appeal to these consumers. Moreover, the use of environmentally sustainable practices has shown to enhance brand image in the minds of customers.
In certain industries, the use of biodegradable plastics can save time. Many crops, for example, are covered in thin polypropylene mulch. This has to be collected and recycled every season. If a bioplastic mulch is used instead,it can simply dissolve and even improve the carbon content of the soil. Similarly, compostable utensils can help restaurants save time in sorting waste.
