Valuable resources are extracted every day to develop convenient products such as bottles, containers and more. As the extraction of virgin resources rapidly depletes the availability of such, it is high time a sustainable alternative is fetched, to ensure longevity and liveability for future generations.
With the prices for virgin material on the rise, the alternative, which is waste that can be recycled, is staring at us from the roadsides, canals and landfills. If we collect and recycle the waste plastic bottles around our island, the need to import approximately 1000-1300 tonnes of polyethylene terephthalate (PET) every month would significantly reduce, and help revive the environment and economy as well.
60% of the monthly PET plastic in Sri Lanka is circulated within the Western Province. Unless measures are taken to collect and dispose of waste plastic effectively, the requirement to import plastic will continue to rise, and the potential for a resilient circular economy and improved livelihoods in the recycling sector will eventually disappear.
Bottle-to-Bottle: a better solution?
One of the easiest solutions is to bring plastic back into the system and recycle it to produce a bottle again. But, that’s hardly a reality. Why? Sri Lanka doesn’t legally allow recycled content in food-grade manufacturing.
According to the Extraordinary Gazette Notification No. 1160/30 of 29th June 2010 “any food in any package, appliance, container or vessel that has been made from recycled plastic” is prohibited. Thus, there is a fear around using recycled plastic in food-grade packaging in terms of quality and impact on the health of the end consumer.
However, around the world, countries are embracing this concept, committing to world-class standards and implementing the bottle-to-bottle concept to efficiently curb plastic waste pollution, while also giving back to their economy and local communities. Developed and developing economies such as the USA, Canada, Europe, Brazil, Bangladesh and Nigeria allows recycled PET in food-grade packaging, which scales down on the use of virgin resin in manufacturing.
For example, the level of PET bottle recycling in Japan is one of the highest in the world, and this was made possible by the Containers and Packaging Recycling Act (1995) which was implemented to promote the segregated collection and recycling of containers and packaging waste. The Government of Japan designates three types of recycling processes; Material, Chemical and Thermal recycling. PET plastics fall under the ‘Material’ category, where PET bottles are made into new PET products.
In Indonesia, Coca-Cola plans to set up a new recycling facility, which will help eliminate the use of virgin plastic. The facility will house a bottle-to-bottle grade PET recycling facility where the use of recycled plastic could reduce the amount of new plastic resin the company uses by an estimated 25,000 tonnes each year. Through this venture, Coca-Cola hopes to play a critical role in supporting Indonesia’s plastic waste management issue, while creating an impact on the country’s circular economy as well.
Moreover, in evident efforts to save foreign exchange and successfully battle against the war of pollution, the bottle-to-bottle concept is approved in many countries. The case in Sri Lanka should be no different. As this concept is also approved by The United States Food and Drug Administration (FDA), Lankan authorities should follow suit and save valuable foreign exchange by converting waste PET back to a bottle. Currently, Sri Lanka spends up to USD 1,550 per ton, per month in foreign reserves for the importation of PET plastic, where approximately 1000-1300 tons of PET is imported per month.
Additionally, recycling PET bottles to their original form can be done more than 7-8 times, where the process is much more affordable and less harmful to the environment, as PET plastics produce 3 times less CO2 in production when compared to an alternative material such as glass.
Using modern and advanced machinery in the recycling process, the intrinsic viscosity (IV) level, which is the strength of a bottle, will not only be kept stable but increase as well.
So if the underlying benefits are clear and extremely advantageous to all Sri Lankans, why hasn’t this concept been implemented?
Waste management: a need for stronger reform
From a holistic point of view, one of the biggest issues in Sri Lanka’s waste management system is the poor implementation of proper waste collection. From rural households to the urban West, to the authoritative bodies in the country, a responsibility to segregate and dispose of plastic waste appropriately must be indoctrinated.
Primarily, every household should ideally have 4 separate designated bins to collect organic waste, paper waste, glass and metal waste and plastic waste. This way, collectors can collect the less contaminated plastics and give them to the recyclers.
In Japan, households are encouraged to sort their waste at home as they are provided with specific containers for PET bottles, PS foam containers, and PP bottle caps separately, instead of mixing them with other plastics. They are further encouraged to utilise segregated disposal methods such as PET bottle shredders provided at supermarkets for consumers to dispose of their used PET bottles, after which they can collect store credit or shopping tokens. Japan’s impressively high plastic recycling rate is owed to its local Governments’ sorting rules, which are some of the strictest in the world.
In Sri Lanka, most people look up to the Government to address this issue, but the truth is told, the infrastructure and practices in place are outdated and inefficient. In essence, the local Government’s policy decisions in the waste management and recycling arenas have been extreme, often overlooking the long-term economic and environmental benefits that could be availed, in favour of an ‘easy-fix’ ban.
Local authorities are also a key stakeholder in ensuring proper and efficient waste segregation and management system. Their support in raising awareness and imposing strict rules and penalties to maintain proper waste segregation will not only empower the local recycling industry, but also reflect well as people now want to recycle, but the issue prevails in collection efforts.
Therefore, the local communities and the Government must take a strong stance in handling the country’s waste management issue, as the long term economic and environmental benefits definitively outweigh the complications and issues created by either neglecting the concerns in the local waste management and recycling sector or simply chucking the problem under the rug with another ‘ban’.
Waste management efforts must be strengthened so that waste plastic makes its way into the recycling economy. An easy solution to the plastic waste issue is also to have plastic go back into the system. However, this is currently prohibited in the country as it has been gazetted as mentioned above. Allowing recycled material to be used in food-grade packaging will further increase the demand for plastic recycling, a critical priority in our island nation.
