“…Porous carbon hierarchical structures based on wood cellulose are frequently studied as electrodes in supercapacitors or in batteries [ 256 , 257 ]. Various cellulose raw materials including agro waste can be applied to form porous hierarchical carbon structures [ 258 ]. Carbonized cellulose structures have a wide range of potential applications.…”

Cellulose is the most abundant natural polymer and deserves the special attention of the scientific community because it represents a sustainable source of carbon and plays an important role as a sustainable energent for replacing crude oil, coal, and natural gas in the future. Intense research and studies over the past few decades on cellulose structures have mainly focused on cellulose as a biomass for exploitation as an alternative energent or as a reinforcing material in polymer matrices. However, studies on cellulose structures have revealed more diverse potential applications by exploiting the functionalities of cellulose such as biomedical materials, biomimetic optical materials, bio-inspired mechanically adaptive materials, selective nanostructured membranes, and as a growth template for inorganic nanostructures. This article comprehensively reviews the potential of cellulose structures as a support, biotemplate, and growing vector in the formation of various complex hybrid hierarchical inorganic nanostructures with a wide scope of applications. We focus on the preparation of inorganic nanostructures by exploiting the unique properties and performances of cellulose structures. The advantages, physicochemical properties, and chemical modifications of the cellulose structures are comparatively discussed from the aspect of materials development and processing. Finally, the perspective and potential applications of cellulose-based bioinspired hierarchical functional nanomaterials in the future are outlined.

“…26 It has been shown that organic municipal solid wastes (OMSW) and agricultural wastes are potential raw materials for production of enzymes. [27][28][29][30][31] The OMSW has about 70-80% organic content of which ∼89% is cellulosic that might be a potential source of raw materials for production of cellulase. With the view to produce industrially important cellulase from cellulosic OMSW, it is very important to obtain the cellulolytic organisms and their cellulase encoding genes for production of recombinant cellulase more efficiently.…”

Cellulases are used in textile, pulp and paper, brewery and wine, sugars, and ethanol industries. Four fungal isolates obtained from organic municipal solid wastes (OMSW) were selected based on their cellulolytic activity on carboxymethyl cellulose (CMC) agar medium. Based on the internal transcribed spacer (ITS) sequence of the ribosomal DNA, the four cellulolytic isolates were identified as Aspergillus fumigatus AKAL1, Aspergillus oryzae AKAL4, Aspergillus flavus AKAL8, and Aspergillus flavus AKAL9. After 9 days of fermentation at 30°C and pH 6.5 under 110 rpm agitation, these isolates produced the maximum amount of cellulase. The cellulase showed optimum activity at temperature 35–40°C and pH 6.0–7.0 and was stable for 1 h at 25–45°C and pH 5.0–7.0. The Mg2+ and Zn2+ significantly increased but Hg2+, K+, and Ca2+ severely repressed the cellulase activity. Degradation of filter papers and bio‐stoning of denim was successfully done with the crude cellulase. An endo‐β‐1,4‐glucanase was isolated and characterized from Aspergillus isolates. Genome‐wide analysis revealed that the genomes of A. oryzae, A. fumigatus, and A. flavus, the pertinent species of the fungal isolates, had 23, 25, and 22 cellulase genes, respectively. Phylogenetic analysis revealed that the cellulases in these fungal species were divided into three major groups, and the isolated endo‐β‐1,4‐glucanase clustered to Group II. Ten different motifs are present in cellulases of the three species. Results herein provide a valuable resource for understanding cellulase genes in Aspergillus species and potential application of cellulase in textile and fermentable sugars production industries.

“…In addition, AC production from agri-food waste, due to its good conductivity, stability, large and modifiable surface area, has been used in the construction of batteries for portable electric devices and hybrid vehicles, where they are a part of the so-called supercapacitors [58,59].…”

The agri-food industry is a source of various substrates -plants as well as plant and animal residues or waste, which can be recycled. Determining the yield of agri-food waste processing products that can be obtained from them, as well as estimating the local availability of a given raw material allows for the selection of appropriate substrates that guarantee both their effective production and their continuous supply. The presented article includes a review of scientific reports on the acquisition of bioactive substances, substrates for the production of activated carbon and materials for use in construction from waste from the agri-food industry. Moreover, the article discusses the economic aspects of agri-food waste in terms of bioeconomy.
