Background The production of single-use plastics (SUP) is increasing and has become one of the most pressing environmental problems. Scope and approach This review evaluates the environmental aspects of SUP in the packaging industry, considering challenges, impacts and global policies. The focus is on biodegradable packaging alternatives, certification standards, consumer behavior, and the critical role of R&D and patents in moving towards a circular economy. This report integrates discussions on bans and taxes on SUP globally and proposes comprehensive strategies, including extended producer responsibility and consumer education. The technological status and trends in biodegradable plastics are addressed. The impact of certification standards and patents are examined. Consumer demand for eco-friendly packaging is explored, highlighting the complexity of purchasing behavior influenced by demographic and economic factors as well as marketing strategies. The phenomenon of greenwashing and the importance of transparent environmental labeling are also addressed. Key findings and conclusions Global efforts to curb SUP have led to a 68% reduction in polyethylene bags in some regions. Legislative action against SUP is essential, especially for packaging, which accounts for 53% of SUP. Biodegradable plastics currently account for 0.5% of the 400 million tons of plastics produced annually. 44% of patents filed worldwide for biodegradable polymers relate to packaging. Their growth depends on strict standards, transparent certifications and the priority of environmental integrity over the market. The growing demand for biodegradable packaging based on sugar cane, cassava and corn starch reflects consumer awareness. Real progress is hampered by the mismatch between consumer intentions and behavior, economic constraints and greenwashing. A solid legal framework, eco-labels and environmental education are essential.
