My City My Responsibility - Future of the Story of Plastic!

Dear All,

PPE made of Plastic

Plastic an ubiquitous thing on earth and is quite indispensable for most of us whether we like it or not. Yet this invention has now become an evil for the environment due to innumerable reasons.  When it comes to sustainability, plastic appears to be one of those materials that can be very efficient, cost effective and user friendly. However plastic waste disposal is a global problem that is choking up our oceans, filling our lands and entering our food chains. These thoughts were triggered after watching the documentary titled Story of Plastic aired on the occasion of this year's Earth Day. 

This documentary not only shows how big is the plastic pollution problem but also shows where does it come from and how it is a systemic problem than just an individual's choice. It captures the entire supply chain right from the use of petroleum to produce plastic to plastic pollution to its implications for climate change. Indeed it is an eye opening documentary when it comes to the life threatening impacts of plastic pollution. It pictures how managing the plastic waste is bigger challenge for developing countries where the plastic wastes are being shipped all the way by the developed nations. But when plastic wastes are no more accepted by the developing countries, how ineffective recycling plants create downgraded plastic products that cause even much more harm. Plastic pollution and its linkages with poverty, cheap labor and women who are involved in the overall process of sorting the wastes, recycling and processing especially in India have been highlighted as well. However packaging material and consumption of single-use plastic products like straws, carry bags and shampoo or food sachets etc pose bigger challenges of disposal, is the ultimate issue that we have been grappling with as per the documentary while the mismanagement of plastic is just an excuse to get away from the hidden agenda of the petroleum companies.

Given all these facts and concerns, the movie fails to effectively showcase the way forward apart from a ban on single use plastic and packaging material. The movie completely disregards the benefits of plastic especially if we consider the current pandemic scenario where PPE's made out of plastic have been the most efficient and easily affordable material for our safety.

I believe it is important to understand that even if we ban plastic completely today, an existing single waste bottle will take upto 450 years to decompose. From the entire host of plastic products that we consume to the huge plastic products that we use, its quite obvious that plastics are here to stay forever. So definitely banning plastic may not be that helpful, however can we explore and have stringent policies in place in order to phase out the production of virgin plastic along with creating complex recycling techniques that are effective, local and low cost that will ensure upcycling plastic waste into a much better and more durable and eco-friendly product? One such local example that quickly comes to my mind is of Aarohana Ecosocial development a plastic upcycling initiative by Amita Deshpande where plastic carry bags are cleaned and woven into attractive handbags, purses and mats that even generate local livelihoods for women. Inspired by Khamir, a platform in Kachchh that promotes indigenous knowledge on handicrafts and allied cultural practices for creation and preservation of local communities.

From the packaging problem perspective, a global standardization for packaging can be adopted that will improve recycling and ease resource recovery which in turn will enable circular economic models. As per Our World in Data statistics, mismanaged plastic waste is generated highly by the high income groups versus low income groups, but that is mostly due to accessibility, its not that the low income groups are wiser! Also countries having longer coastlines have seen tremendous mismanaged plastic wastes. So the question of managing plastic waste can be tackled only with the help better segregation and effective waste management infrastructure.  

When we talk about segregation another challenge is the segregation within the various plastic items, because some products like transparent PET bottles can be easily recycled or reused, while some products may need complicated processes in order to recycle them. The used PPE's are of hazardous nature and will have to be incinerated right away. For such products we need more effective technologies for incineration that are least polluting. Given the nature of plastic and its versatility, we need to explore for more such processes where a plastic waste turns out to be the raw material for another product.

Now that there is so much plastic in nature, some bacteria and fungi have started evolving the ability to eat it. Apart from recycling, such interesting ways to deal with plastics wastes are upcoming. Another concept of producing bioplastics from startch are already available, however problems with this plastic is about its look and feel which is exactly same like ordinary plastic and hence differentiating it is difficult plus its also a controversial issue when it comes to food security. Hence there's a lot of scope for research in this field to produce sustainable polymers.

In one of my earlier blogs I did mention why plastics were ever invented. A lot of scope lies for sustainable innovation given the technological advances today, industries have a great role to play. Better quality of plastics can be produced that have low carbon footprint and hence can reduce pollution. The idea is to no longer term plastic as WASTES but as a KEY resource and start reusing it at source. Many individuals do come up with innovative ways that ensure their plastics don't end up in a landfill or an ocean. A more systemic approach will help to solve the plastic problem that involves engaging public sector as well as private sector to pitch for effective enforcement of existing policies and strategies. 

In October 2018, UN Environment programme and the Ellen Mcarthur Foundation announced the New Plastics Economy Global Commitment with more than 290 signatories having a common vision to treat plastics at source based on circular economy models. One of the pioneers in circular economy has been the Banyan Nation who are converting collected post consumer and industrial plastic waste into high quality recycled granules which are termed as Better Plastic that has strength as good as virgin plastic. There are several such examples already who are using plastic as a resource for better economic gains. Its time we start valuing plastic as a raw material and use it effectively for the betterment of the environment.
