“…Studies on the role of spent mushroom substrates after this cultivation produces many important materials, such as enzymes [12,19,126,127], biomass [118,128,129], bioethanol [19,127,130], feed ingredients, and functional foods [61,131,132]. Spent mushroom substrates can be recycled as a substrate for the "new cultivation cycle" of mushrooms, a feedstock for producing the second generation of biofuels, a bio-control agent, a biofertilizer, and for soil amendment [133][134][135]; 2.…”

The field of biotechnology presents us with a great chance to use many organisms, such as mushrooms, to find suitable solutions for issues that include the accumulation of agro-wastes in the environment. The green biotechnology of mushrooms (Pleurotus ostreatus L.) includes the myco-remediation of polluted soil and water as well as bio-fermentation. The circular economy approach could be effectively achieved by using oyster mushrooms (Pleurotus ostreatus L.), of which the substrate of their cultivation is considered as a vital source for producing biofertilizers, animal feeds, bioenergy, and bio-remediators. Spent mushroom substrate is also considered a crucial source for many applications, including the production of enzymes (e.g., manganese peroxidase, laccase, and lignin peroxidase) and bioethanol. The sustainable management of agro-industrial wastes (e.g., plant-based foods, animal-based foods, and non-food industries) could reduce, reuse and recycle using oyster mushrooms. This review aims to focus on the biotechnological applications of the oyster mushroom (P. ostreatus L.) concerning the field of the myco-remediation of pollutants and the bio-fermentation of agro-industrial wastes as a sustainable approach to environmental protection. This study can open new windows onto the green synthesis of metal-nanoparticles, such as nano-silver, nano-TiO2 and nano-ZnO. More investigations are needed concerning the new biotechnological approaches.

“…A large number of discarded wastes of many crops every year was produced along with the crop production, which may cause environmental problems and have potential safety hazards [41]. Globally, about 5 billion tons of bio-wastes are generated annually from agricultural activities [42]. These wastes are the main source of a huge amount of cellulose every year, such as banana rachis, coconut husk fiber, grain straw, grape skin, garlic peel, soy hulls, and sugarcane bagasse [43].…”

“…The synthetic material-based composites should be replaced by natural ones in several manufacturing industries, such as the field of textiles, which flax was used in ancient Egypt nearly 7000 years ago [3]. The cellulose is the most important component of the lignocellulosic natural fibers, which many plants could order their content of cellulose (%) as follows straw of rice (41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51)(52)(53)(54)(55)(56)(57), leaf of date palm (46), leaf of abaca (56)(57)(58)(59)(60)(61)(62)(63), bast of jute (61)(62)(63)(64)(65)(66)(67)(68)(69)(70)(71), leaf of banana , leaf of sisal (65), bast of hemp (68), bast of ramie (68.6-76.2), bast of flax (71), bast of kenaf (72), leaf of curaua (73.6), leaf of pineapple (81), bast of nettle (81)…”

Sustainable Applications of Nanofibers in Agriculture and Water Treatment: A Review

et al. 2022

Natural fibers are an important source for producing polymers, which are highly applicable in their nanoform and could be used in very broad fields such as filtration for water/wastewater treatment, biomedicine, food packaging, harvesting, and storage of energy due to their high specific surface area. These natural nanofibers could be mainly produced through plants, animals, and minerals, as well as produced from agricultural wastes. For strengthening these natural fibers, they may reinforce with some substances such as nanomaterials. Natural or biofiber-reinforced bio-composites and nano–bio-composites are considered better than conventional composites. The sustainable application of nanofibers in agricultural sectors is a promising approach and may involve plant protection and its growth through encapsulating many bio-active molecules or agrochemicals (i.e., pesticides, phytohormones, and fertilizers) for smart delivery at the targeted sites. The food industry and processing also are very important applicable fields of nanofibers, particularly food packaging, which may include using nanofibers for active–intelligent food packaging, and food freshness indicators. The removal of pollutants from soil, water, and air is an urgent field for nanofibers due to their high efficiency. Many new approaches or applicable agro-fields for nanofibers are expected in the future, such as using nanofibers as the indicators for CO and NH3. The role of nanofibers in the global fighting against COVID-19 may represent a crucial solution, particularly in producing face masks.

“…However, a few agro-industrial wastes are not adequately exploited due to their structural stability [ 1 ]. Lignocellulosic, chitinous, and keratinous biomass are the most ubiquitous biopolymers contributing to the rise in carbon footprint [ 2 ], with keratinous materials being unusually recalcitrant to natural degradability because of the high keratin contents [ 3 ].…”
