The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Our plastic age (2009, background): “Widespread public awareness of these materials and effective infrastructure for stringent control of certification, collection, separation and composting will be crucial to obtaining these benefits in full’ (Song et al. 2009).”
Sustainability assessments of bio-based polymers (2013, background): “As noted by Song and colleagues, “although it is feasible tomechanically recycle some bioplastic polymers such as PLA a few times without significant reduction in properties, the lack of continuous and reliable supply of bioplastics polymer waste in large quantity presently makes recycling less econ”
Abiotic and biotic environmental degradation of the bioplastic polymer poly(lactic acid): A review (2017, background): “waste management strategies to direct PLA plastics to commercial composting facilities will greatly reduce risk [23,56].”
Plastics, the environment and human health: current consensus and future trends (2009, background): “However, life cycle analyses are required to help establish the most appropriate usage, disposal (e.g. Song et al. 2009 illustrate relatively slow degradability of PLA in home composting) and hence labelling, of biopolymers such as this (WRAP 2009).”
