Biodegradable Smart Packaging: A Cross-Disciplinary Approach to Combat Plastic Pollution
AI summary Read the abstract
This review examines biodegradable smart packaging as a cross-disciplinary solution to plastic pollution, discussing materials such as polylactic acid, polyhydroxyalkanoates, and starch-based composites, and exploring how intelligent functionalities can be integrated into environmentally friendly packaging alternatives to replace the 300 million tons of plastic produced annually.
Plastic pollution has emerged as one of the most persistent and destructive environmental issues of our time. With over 300 million tons of plastic produced annually, much of it used for packaging and discarded within minutes, ecosystems around the globe are overwhelmed with synthetic waste. This environmental emergency calls for innovative, sustainable, and systemic responses. Biodegradable smart packaging represents one such cross-disciplinary innovation that not only offers an environmentally friendly alternative to conventional plastics but also introduces intelligent functionalities that improve product quality, safety, and traceability. This paper investigates the science, applications, and policy dimensions of biodegradable smart packaging, combining insights from material science, digital technology, environmental engineering, and industrial design. It aims to identify pathways for scalable implementation, assess consumer perception, and outline the infrastructural and regulatory frameworks necessary for mainstream adoption.
