Our Position on Sustainability

Sustainability outcomes are embedded in our core business strategy, prioritizing three Impact Pathways: Product Stewardship, Responsible and Efficient Operations, and Partnership for Sustainable Progress.

Sustain Product

Product Stewardship

Utilizing a comprehensive lifecycle approach, CSI has embedded circular principles in all new product research and development, evaluating every aspect for improvements – from materials and design to packaging and transportation.

Responsible Closure Designs

Post Consumer Recycled Material

PolyCycle® is a new Post-Consumer Recycled (PCR) resin developed to comply with stringent food and beverage packaging requirements. Innovated by Closure Systems International, Inc. (CSI), PolyCycle® PCR resin closures meet performance requirements across five markets and has earned FDA-approval.

Our closures are 100% recyclable at all standard recycling centers, helping to divert solid waste from landfills.

Bio Feedstock

As alternative packaging materials gain traction with consumers, CSI is evaluating bio-resins and biodegradable plastics as options to reduce a products’ environmental impact.

Biodegradable plastics have many unique properties which can offer certain additional advantages during use and/or waste management, e.g. reduced processing time, water-soluble, etc.

Like other plastics waste, biodegradable plastics waste can be included in material recovery to be recycled or reworked by the converter, it can also be composted and/or digested anaerobically.

Tethered Closures

CSI’s Twist & Flip® Tethered Closure delivers a robust, sustainable solution to evolving legislation in the beverage industry. With intuitive easy opening for consumers, the precision-engineered hinged design increases the recyclability of the closure by ensuring it stays attached to the bottle throughout the product’s lifecycle.

Flip-top Closures

Our research and development efforts are leading the way in a next generation of flip top offerings that ensure the closure stays with the bottle for recycling.

All of our new sustainability technologies meet the requirements of existing and potential legislation.
