Book excerpt: Packaging plays a major role in the environmental footprints of products from any industrial sector, and thus is important to address the sustainability issues of packaging.

Plastic packaging is one of the most common element and the packaging sector accounts for almost 40% of plastic pollution in the world. Sustainable packaging is the only way forward to alleviate the environmental devastations from the the packaging sector. This book presents case studies and discusses how to make packaging more sustainable for a better future. ​
