One of the main criticisms that have been leveled at biodegradable plastics is that some materials will biodegrade in industrial composting systems, but less reliably so in home composts or ocean water. Other materials have even been shown to merely fragment rather than fully biodegrade, which only further exacerbates the negative environmental impacts of plastic products.
However, the industry has remained steadfast in its dedication to solving this challenge, and 2018 has produced several promising advances in biodegradable plastics. This has been the case particularly with polyhydroxyalkanoate (PHA) products. There have been several developments around the capabilities and production of PHA in 2018, and they will likely have a great impact on the industry going into 2019.
