“…Reported as carbon neutral life cycle material, PLA can also be produced from food waste, e.g ., fish, rice bran, vinification lees, soy protein hydrolyzate, and unpolished aged rice, among others ( Shi et al, 2018 ; Tsang et al, 2019 ), being an appropriate material to promote a circular, sustainable and less wasteful economy ( Jribi et al, 2020 ). Recent studies show that several technologies have been developed so as to produce PLA materials comparable to those obtained from petroleum-based polymers ( Asgher et al, 2020 ; Farah et al, 2016 ; Garcia-Garcia et al, 2020 ; Kalita et al, 2020 ). Various types of food with a wide range of water activity (a w ), pH and composition have already been packaged and marketed with PLA-based materials, including potato chips, ready-to-eat salads, yogurts, citrus juices, and water ( Gerometta et al, 2019 ).…”
