However, due to slow reaction rates, there is a lack of an industrially viable biodegradation strategy for most plastics. Here, we highlight the applicability of a thermophilic biodegradation strategy over a mesophilic approach, to enhance enzyme accessibility and catalyze plastic biodegradation. Thus, at reactions closer to the melting temperature or glass transition temperature of plastics, thermophilic reactions can offer an alternative direction to conventional plastic biodegradation strategies.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"articleInformation\">Article info<\/h3>\n\n\n\n<h3 class=\"wp-block-heading\">Publication history<\/h3>\n\n\n\n<p>Published online: April 28, 2023<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Publication stage<\/h3>\n\n\n\n<p>In press, corrected proof<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Identification<\/h3>\n\n\n\n<p>DOI:&nbsp;<a href=\"https:\/\/doi.org\/10.1016\/j.tibtech.2023.03.016\">https:\/\/doi.org\/10.1016\/j.tibtech.2023.03.016<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Copyright<\/h3>\n\n\n\n<p>\u00a9 2023 Elsevier Ltd.
