Closing the Loop for a Better Future
Listening Sessions Identify Stakeholders’ Top Goals
By Zach Muscato, Corporate Sustainability Manager at Plastic Ingenuity
The packaging industry has a shared ambition to become more sustainable, and materials scientists and manufacturers play a pivotal role increasing the circularity of plastics. For example, polyethylene terephthalate (PET) plastic is recyclable, and it was designed to be remade into new items, including carpets, clothing and beverage bottles. However, there is a misconception that PET bottles are single-use packaging.
Businesses are setting goals to improve the sustainability of their packaging, and we have conducted multiple listening sessions to identify their priorities. We have spoken to a diverse group of stakeholders from retail, healthcare and consumer packaged goods (CPG) organizations. Participants include various packaging subject matter experts, including packaging engineers, sourcing and procurement professionals, operations managers, marketing experts and sustainability leaders.
Stakeholders frequently mention corporate responsibility and accountability as drivers in the circularity movement, and share a common goal to minimize harmful outcomes on people and the environment.
Analyzing sustainability priorities
Minimizing plastic material usage was a goal for 87% of respondents, and 60% marked it as a top pick. This can entail eliminating plastic packaging material entirely, or shifting to plastic alternatives. As a close second, 80% of stakeholders are focused on maximizing PCR content (post-consumer recycled material) in their packaging to improve circularity. Additionally, 73% of stakeholders say using recyclable materials is a goal their organizations are pursuing, and nearly half prioritize using the How2Recycle instructions to provide clearer guidance to their consumers.

Calculating the return on investment
Cost and profitability are top of mind when businesses evaluate the effect of circularity and sustainable packaging efforts. Yet minor changes, when multiplied across business operations, can have significant impact. For example, initiatives such as downgauging, right-sizing and component elimination will typically decrease packaging system costs.
Adding PCR to packaging is critical to enhance circularity, but supply constraints and price pressures can pose challenges. Another improvement with an associated cost premium is using labels and adhesives more conducive to the recycling process. Furthermore, food producers are mindful of the harmful climate change implications of food waste and will not make any packaging changes that could potentially increase the risk.
Consumer influence, legislative policy, non-governmental organization (NGO) leadership and retailer directives are currently the main influencers on organizations’ sustainability strategies. But that will only go so far. Stakeholders across sectors recognize that existing recycling programs and infrastructure will need improvements to fully realize circularity and sustainability goals.
Forming a better future
Emerging technologies have vast potential in shaping the future of packaging sustainability initiatives. Advanced recycling, also called chemical recycling, was most recognized by survey respondents. Plus, many stakeholders are excited about the possibilities of new material additive technology.
When packaging is designed with the intent to be recycled, the packages that touches millions of lives – from preserving food to protecting medical devices – are optimized to be recovered at the end of their useful cycle. At that point, organizations essentially become their own material suppliers. Through investments, partnerships and mutual passion, the packaging industry can help close the loop and advance to a circular economy.
