“…The implementation of a circular bio-economy based on the efficient bioconversion of agro-industrial residues by selected yeast species/strains is an important societal challenge [ 1 , 2 , 3 ]. Agro-industrial residues can serve as low-cost raw material for the biotechnology industry, and these organic wastes are sources of carbon, nitrogen and other nutrients for microbial growth and metabolite production while decreasing their negative effects as environmental pollutants [ 4 , 5 ].…”

Agro-industrial residues are low-cost carbon sources (C-sources) for microbial growth and production of value-added bioproducts. Among the agro-industrial residues available, those rich in pectin are generated in high amounts worldwide from the sugar industry or the industrial processing of fruits and vegetables. Sugar beet pulp (SBP) hydrolysates contain predominantly the neutral sugars d-glucose, l-arabinose and d-galactose, and the acidic sugar d-galacturonic acid. Acetic acid is also present at significant concentrations since the d-galacturonic acid residues are acetylated. In this study, we have examined and optimized the performance of a Rhodotorula mucilaginosa strain, isolated from SBP and identified at the molecular level during this work. This study was extended to another oleaginous red yeast species, R. toruloides, envisaging the full utilization of the C-sources from SBP hydrolysate (at pH 5.0). The dual role of acetic acid as a carbon and energy source and as a growth and metabolism inhibitor was examined. Acetic acid prevented the catabolism of d-galacturonic acid and l-arabinose after the complete use of the other C-sources. However, d-glucose and acetic acid were simultaneously and efficiently metabolized, followed by d-galactose. SBP hydrolysate supplementation with amino acids was crucial to allow d-galacturonic acid and l-arabinose catabolism. SBP valorization through the production of lipids and carotenoids by Rhodotorula strains, supported by complete catabolism of the major C-sources present, looks promising for industrial implementation.

“…DCs, as well as the chopstick waste, belong to the category of lignocellulosic materials, which are the most abundant and available biodegradable resources on Earth (Zuin et al 2018). Nowadays, a variety of technologies are available for the conversion of biomass or bio-waste to different energy forms including biochemical, thermal chemical, and physical processes (Qiu and Hu 2013;Fieschi and Pretato 2018).…”

With the rapid advancement of online food delivery and takeaway markets, the use of disposable chopsticks has exponentially increased in China, resulting in the reduction of forest resources and the generation of large amounts of chopstick waste. This review summarizes a variety of methods to produce eco-friendly chopsticks with the aim of enabling a second life cycle for chopstick waste. The related practical recycling systems and policies based on government experience in developed regions are proposed. Furthermore, perspectives with regard to the future development of waste chopsticks recycling systems are also discussed.

“…Currently, plant-derived natural pigments have been used as supplements or additives in the cosmetics, food, pharmaceuticals, livestock feed, and other applications. [46,47] A green method based on ILs-assisted extraction and preconcentration of natural pigments was described using ultrasound-assisted extraction coupled with dispersive micro solid-phase extraction. The pure chitosan nanoparticles (CS NPs) were then utilized as a sorbent under microextraction mode.…”

The evolution of petroleum‐derived polymers is one of the crowning accomplishments of the past century. Although the significant economic gains from this industrial model of resource utilization are achieved, the environmental impacts are fatal. One of the principles of sustainable development is to replace such polymers with potential alternatives derived from renewable materials. Biopolymers derived from natural resources afford a new, versatile, environmentally benign feedstock that could exhibit closed‐loop life cycles as part of a future material's industrial ecology. However, the solubility and processability of biopolymer materials provoke a serious bottleneck owing to their dense networks of inter ‐ and intramolecular bondings and structural heterogeneity. Recently, ionic liquids (ILs) have emerged as promising green solvents and acquired augmented appreciation for their peerless power of biopolymer processing. Among the fourteen principle of green chemistry, the two key elements encourage the exploitation of renewable raw materials by using environmentally benign solvents that cover in dissolution of biopolymers using ILs. This mini review represents a brief overview of the comprehensive ILs assisted extraction and processing of various biopolymeric materials for value‐added applications.
