Creating a circular economy for plastics
A circular economy is inherently restorative and regenerative, emphasizing the continuous flow of materials within a closed-loop system, as opposed to single-use and disposal. Specifically regarding plastic, the aim is to retain its value within the economy while preventing any leakage into the natural environment. However, achieving this goal is more challenging in practice than in theory. Shifting society away from the conventional "take, make, dispose" approach ingrained in business models demands a fundamental reconsideration. This entails enhancing recycling efforts, encouraging reuse practices, establishing a market for recycled materials, and redesigning products with their end-of-life phase in consideration.
Boosting demand for Recycled Plastic A major obstacle hindering the establishment of a circular plastics economy is the ineffective market for recycled plastics. This presents a significant challenge in boosting global recycling rates. Currently, most plastics are derived from fossil fuels, which are more economical than recycled materials. Consequently, the economic viability of plastic recycling is compromised.
Despite numerous companies setting ambitious goals for recyclability, few consider their responsibility in fostering demand by stimulating markets for recycled materials. To address this, companies need to prioritize the utilization of post-consumer resin (PCR) whenever feasible. This proactive approach will help create demand for recycled materials, thereby establishing crucial end markets and ensuring the sustainability of domestic recycling efforts.
Closing the loop with chemical recycling
While mechanical recycling faces limitations due to contamination and challenges in material separation, chemical recycling offers a distinct process wherein materials are broken down into their original chemical components, allowing for their reconstruction into new products.
One promising aspect of chemical recycling is its ability to convert waste plastic into food-grade rPET, sourced not only from plastic bottles but also from ocean waste and polyester textiles. Despite being overshadowed in public discussions about plastic waste due to insufficient investment and infrastructure, chemical recycling is now experiencing significant innovation and attention.
A circular economy for plastics presents a hopeful prospect for mitigating the issue of plastic waste. However, achieving a fully operational closed-loop system necessitates increased collaboration from all stakeholders along the value chain. The recent introduction of the New Plastics Economy Global Commitment, an unprecedented collaborative effort aimed at establishing a transformed paradigm for plastics, signifies a positive stride forward.
Let’s Look into some of the key considerations
Strive for economies of scale: Back projects and initiatives that enhance the economic viability of recycling infrastructure and recycled polymers.
Adopt a comprehensive perspective: Companies must extend their concern beyond their own materials and composition, considering their impact on the broader collection and recycling system.
Balance local and global considerations: While plastic waste poses a global challenge, effective solutions must be tailored to local contexts to ensure lasting impact, given the diversity of infrastructure worldwide.
Foster collaboration to drive innovation: Collaboration among resin suppliers, packaging manufacturers, brands, waste contractors, and recyclers is essential for building a circular economy that benefits society as a whole.
Maintain a long-term outlook: Companies that invest in the long term stand to gain significant commercial rewards as recycling infrastructure and technology mature, and packaging design advances.
