New data from Appleyard Lees\u2019 Inside Green Innovation: Progress Report<\/em> highlights record levels in bioplastic and chemical recycling patent applications, reflecting ongoing innovation in sustainable materials despite economic challenges.<\/p>\n

The report<\/a> indicates an increase in both bioplastic filings and interest in chemical recycling technologies, with particular progress noted in Polyhydroxyalkanoates (PHAs), a promising bioplastic with natural biodegradability.<\/p>\n

Bioplastic patent filings reach new heights<\/h2>\n

In 2022, global patent applications for bioplastics exceeded 600 for the first time, marking a 10% rise from 2021. The data suggests increased innovation around sustainable plastic alternatives, especially in PHAs, which grew by 58% over the year.<\/p>\n

Unlike other bioplastics such as polylactic acid (PLA), which requires industrial composting, PHAs degrade naturally, offering an environmentally friendly option.<\/p>\n

A significant portion of this activity is driven by companies in South Korea, where governmental policies push for plastic waste reduction.<\/p>\n

Companies like Brazil\u2019s Bioreset Biotecnologia and South Korea\u2019s LG Chemical are among the leading patent applicants, particularly focusing on improving PHA production and its use in various applications, including non-woven fabrics.<\/p>\n
