Several leading soda companies have successfully adopted innovative materials in their can production processes. Nestl, for example, has been a pioneer in the use of alternative plastics and recycling technologies. The company has invested heavily in research and development to create sustainable packaging solutions, including cans made from PLA and PBAT. Nestls efforts have been widely recognized, as the company has received awards for its commitment to sustainability.
Another notable example is Coca-Cola, which has been using recycled aluminum for its cans. The company has committed to using 100% recycled aluminum by 2025, which is more than double the percentage it used five years ago. This initiative has helped Coca-Cola reduce its environmental impact while maintaining the quality and durability of its packaging.
Sunkist, a division of PepsiCo, has also made significant strides in the use of innovative materials. The company has introduced cans made from a blend of PLA and aluminum, combining the benefits of both materials. This approach allows Sunkist to create cans that are both durable and sustainable, positioning the company as a leader in the industry.
One specific case study is worth highlighting: MillerCoors has implemented a closed-loop recycling program where all aluminum cans produced are 95% recycled. They also work closely with suppliers to ensure the use of plant-based materials. MillerCoors has seen a significant reduction in its carbon footprint and has received positive feedback from consumers who appreciate the company's commitment to sustainability. This success not only enhances the company's brand image but also sets a precedent for other beverage companies to follow.
