These facts skew the material selection analysis toward materials that can be disposed of alongside food waste and biodegraded in composting settings. Like PET and PP, paper is also recyclable but differs in that it is also compostable. Paper products often are coated to prevent leakage from liquids. These coatings are a recognized shortcoming of paper products, posing challenges to composters as sources of plastic contamination . Historically, they have included persistent per-and polyfluoroalkyl substances (PFAS) ; however, next-generation coatings, such as biowaxes and PLA, have begun to be phased in . PLA can be industrially composted; however, without improvements in the availability and accessibility of such facilities , PLA items may follow a linear lifecycle . Conversely, CDA can be home-composted , enabling a broader range of end-of-life disposal methods for this material. While composting is not a panacea without environmental impacts, it presents a path to circularity for mixed, readily biodegradable organic waste. Future work should prioritize the development of robust exchange constants for beginningand end-of-life scenarios so their tradeoffs can be compared, like those for GHG emissions, water usage, and environmental lifetime.
