Plastic waste is a multi-faceted downside that requires the involvement and cooperation of many stakeholders, with companies being one of many key gamers. In Half 1: Unraveling the Causes, I elaborated on a few of the principal causes of the plastic epidemic in Asia.
On this half, we’ll delve deeper into the distinctive challenges stakeholders face when making an attempt to deal with the plastic downside, both via lowering, reusing or recycling.
The life cycle of plastics
First, allow us to do a fast run-through of the worth chain of plastics. The infographic beneath is a really simplified depiction of the journey of plastic waste all through its lifecycle.
The life cycle of plastics
Referenced From: OECD (2022, 22 February), Plastic air pollution is rising relentlessly as waste administration and recycling fall brief, says OECD.
The next issues outlined are a few of the most difficult issues to be addressed within the plastic waste area.
Price-effectiveness
The best downside in the case of recycling plastics on a big scale is its value. In response to a McKinsey report, primarily based on present applied sciences and assuming there are not any enterprise mannequin breakthroughs, recycling might solely be worthwhile for about 50 per cent of plastic-waste quantity as we speak. Some elements that contribute to this problem embrace the elevated value of manufacturing of recycled plastics and restricted technological capabilities.

Firstly, the economics of manufacturing recycled plastics comparable to polyethylene terephthalate (PET) is just not within the producer’s favour. There may be an elevated demand from companies, particularly Quick-Transferring Client Good (FMCG) corporations, to incorporate recycled plastics in new merchandise.
Thus, the worth of recycled plastics has been pushed up, inflicting recycled plastics to turn out to be costlier than virgin plastics for the primary time in just a few years. A report from S&P International Platts, a commodity market specialist, reveals that recycled plastic in 2020 prices an additional US$72 (£57) a tonne in comparison with newly made plastic.
This was additional exacerbated by the falling oil costs brought on by the pandemic and a rise in petrochemical manufacturing from the US pushed by the shale fuel increase. With shale oil being a key uncooked materials of virgin plastics, this decreases the price of manufacturing of virgin plastics and dramatically will increase the relative worth of recycled plastics, forcing recyclers in Asia to slash costs by 21 per cent on common.
Nevertheless, the consequences of COVID-19 prolong past the brief time period. The long-lasting impacts are evident within the sheer variety of recycling corporations compelled to close down in Asia because of the sharp lower in demand for recycled plastics.
As seen within the following determine, not solely are merely 58 per cent of recyclers within the listed Asian international locations working as of June 2020, however their common working capacities are at a mere 46 per cent of their full put in capability.
This paints a worrying image of the plastic recycling scene. Ought to they completely depart the trade, the entire recycling functionality would shrink even additional, posing a good larger downside to the already restricted recycling capacities within the area.

Secondly, the recycling course of itself nonetheless faces important technological constraints, making it a pricey endeavour. The costly processes used to engineer alternate options to plastics, particularly chemical recycling strategies, are an enormous deterrent to its adoption on a big foundation. One other key space which nonetheless closely faces technological limitations is waste sorting.
Single-stream recycling, which is widespread in lots of areas, is a system by which all waste supplies, comparable to plastics, papers and metals, are blended right into a single assortment truck. That is handy for shoppers but typically leads to contamination, and supplies should be sorted by each machine and human hand, making it costlier.
The decreased effectivity and elevated value thus pose an ideal problem to the corporate when it needs to scale up the system. Manufacturers want tens of millions of tons of recycled plastic for his or her merchandise, and at present, only a few recyclers can present the identical quantity. At present, only a few corporations can produce at this capability.
High quality of recycled plastics
The standard of recycled plastics is one other key space that must be addressed. Recycling plastics typically results in lower-quality supplies, which diminishes their attractiveness. Greater than 10,000 totally different components can be utilized to make plastics.
Plastics of the identical kind typically comprise totally different combos of components, leading to recycled materials with unpredictable and sometimes suboptimal additive combos. Plus, the lengthy polymer chains that make up these supplies turn out to be barely shorter every time they’re melted down.
That is particularly essential after we have a look at the plastic packaging used for meals, which solely permits for the very best grade of plastic for use.
The restricted recyclability of plastics compounds the issue, as many plastics can solely be recycled two-three instances earlier than their properties degrade past usability. After present process a number of recycling cycles, the plastics finally turn out to be environmentally unfriendly, and they might as soon as once more be subjected to the processes of incineration or be chucked into landfills.
Traceability of plastics
In 2020, Coca-Cola was named the highest plastic polluter on this planet three years in a row, with 13,834 of its discarded plastic bottles discovered mendacity on seashores, rivers and parks in 51 out of 55 international locations that had been surveyed.
This was regardless of its promoting claims that it was “investing in sustainable packaging platforms to scale back (their) carbon footprint”. And Coca-Cola is just not the one one. The prominence of greenwashing in plastic recycling is alarming, and a big a part of the issue lies in an absence of accountability.

“Tracing plastic resolves the anonymity of plastic waste,” Professor Barner-Kowollik of the Queensland College of Know-how opined. That implies that plastic waste might be traced again to the producer, paving the best way for plastic producers to be held accountable for each inch of their waste through laws.
Thus, there must be a technique to assign a novel code to every plastic waste generated and monitor its journey via the plastic worth chain, from manufacturing to disposal, pressurising companies to cope with the waste themselves as a substitute of expediting it to different corporations and even international locations. Traceability therefore presents a novel alternative that startups trying to enter the plastic waste ecosystem can discover.
Lack of correct plastic recycling schemes and insurance policies
Lastly, the dearth of correct plastic recycling infrastructures and enforced schemes is a pertinent space that should be addressed.
With the dearth of correct municipal waste administration programs, many households and firms might not have easy accessibility to methods to get rid of their waste. In flip, which means that plastic waste and waste, on the whole, is not going to be collected repeatedly, and the share of waste collected from the precise complete waste generated can be decrease.
Thus, recycling corporations might face difficulties in acquiring constant and high-quality feedstock, thus reducing their skills to reap economies of scale. As such, the businesses might incur the next value of manufacturing when making an attempt to recycle waste, and this might manifest within the type of increased costs for recycled plastics.
This exacerbates our very first argument on the pricey nature of recycled plastics when in comparison with virgin plastics, additional disincentivising extra corporations from coming into the plastic recycling area.
Subsequent, restricted infrastructural growth by governments additionally implies that there are inadequate and insufficient waste disposal amenities. The dearth of assist and funding from the federal government would additional disincentivise entrepreneurs to discover the plastic recycling area, main present corporates and startups to wrestle when discovering acceptable amenities or companions to deal with bigger volumes of plastic waste.
One of the best ways to scale collaboration is thru markets which have the precise incentives in place. Thus, with out the precise monetary or enterprise incentives, the dearth of structured assist can pose an ideal setback to the expansion of this trade. On a bigger scale, this could even result in the decreased capability of plastic recycling in a rustic.
Partly three, we’ll have a look at a few of the doable options provided by startups, governments, and plenty of extra stakeholders to deal with the plastic downside.
