Lignocellulosic feedstock: A review of a sustainable platform for cleaner production of nature’s plastics

Direct Etherification Reaction of Glycerol Using Alkali Metal Cation (Li+, Na+ and K+) Containing X-Type Zeolites as Heterogeneous Catalysts: Optimization of the Reaction Conditions

“…To the best of our knowledge, this is the first study for increasing the conversion of glycerol and the yields of DG and TG in the heterogeneous catalytic etherification of glycerol through suppressing the formation of oligomers by optimizing the reaction conditions. (19.5) This work 1 The numbers in parenthesis are the yields of each product.…”

“…With increasing concerns about environmental pollution caused by petrochemical products such as microplastics, various studies are being conducted to convert biomass into useful eco-friendly materials [1,2]. In particular, interests in the process for producing diglycerol (DG) and triglycerol (TG) have recently increased due to their various application fields including pharmaceuticals, surfactants, cosmetics, food additives, lubricants, fatty acid ester emulsifiers, plasticizers, biodiesel additives and oligomeric liquid crystals [3][4][5][6][7][8].…”

Sustainability implications of transformation pathways for the bioeconomy

“…Bio-ethylene production, used as a building block for a variety of bulk materials, is already economically competitive in Brazil, as it is based on established technologies; polylactic acid has the highest economic potential both now and in the long term ( Gerssen-Gondelach et al, 2014 ). So far, the production of second generation bioplastics from lignocellulosic feedstock (i.e., from wood or short rotation coppice) outside the context of sugarcane biorefineries in Brazil and Thailand (i.e., from bagasse and molasses), is still far from being profitable ( Carus and Raschka, 2011 ;OECD, 2013c ;Govil et al, 2020 ).…”

Integrated solid-state enzymatic hydrolysis and solid-state fermentation for producing sustainable polyhydroxyalkanoates from low-cost agro-industrial residues

“…Although bioplastics are produced at large scale starting from different substrates such as sucrose, glucose, starch or volatile fatty acids, their contribution to the global plastic market is still limited reaching just 1% of the total production in 2019 (European Bioplastics, 2020). One of the main constraints restraining the development of these products is the fermentation cost, mainly influenced by the acquisition of the raw materials, accounting between 30-50% of the total processing costs (Du et al, 2012;Govil et al, 2020;Rodriguez-Perez et al, 2018). Consequently, the search for economic raw materials and effective bioprocess to obtain PHA has served as driving force to develop alternative systems using renewable sources and waste streams (Govil et al, 2020;Kumar et al, 2020;Rodriguez-Perez et al, 2018).…”

Most of the advances for producing PHA in residue-based systems have been performed by using submerged fermentation (SmF) technologies with raw materials of diverse origin such sugarcane molasses (Acosta-cárdenas et al, 2018), municipal wastewater (Mannina et al, 2020), among others.…”
