Cellulolytic enzyme production from agricultural residues for biofuel purpose on circular economy approach

Analysis of the Circular Economic Production Models and Their Approach in Agriculture and Agricultural Waste Biomass Management

“…The main reason for this is the fact that these CEPMs encourage the development of knowledge, research, and Another relevant term is "waste management" (Figure 10). Twelve percent of the studies are linked to valorization [47,177,179,180] and AWB management [7,44,45] under the approach of the CEPMs (Figure 11). From the analyzed sample, the main valorized residues are tomato leaf waste, rice industrial by-products, banana residue, fruit, and straw remains.…”

“…For example, the Spanish province of Jaen is one of the territories with the highest production of AWB from the olive oil industry [43]. Ten-year legacy of organic carbon in non-agricultural (brownfield) soils restored using green waste compost exceeds 4 per mille per annum: Benefits and trade-offs of a circular economy approach X [175] Bioeconomy and the production of novel food products from agro-industrial wastes and residues under the context of food neophobia 2018 X [176] The bioeconomy of microalgal heterotrophic bioreactors applied to agroindustrial wastewater treatment X [177] Camelina and crambe oil crops for bioeconomy-straw utilisation for energy 2020 X [178] The circular economy of agro and post-consumer residues as raw materials for sustainable ceramics X [50] Cellulolytic enzyme production from agricultural residues for biofuel purpose on circular economy approach 2019 X [179] The management of agricultural waste biomass in the framework of circular economy and bioeconomy: An opportunity for greenhouse agriculture in Southeast Spain X X [7] Co-digestion of by-products and agricultural residues: A bioeconomy perspective for a Mediterranean feedstock mixture 2020 X [180] The potential of plantain residues for the Ghanaian bioeconomy-assessing the current fiber value web X [181] By observing the net developed from the keyword co-occurrence analysis (Figure 10), it can be noted that the term "bioenergy" is the most relevant. In fact, 19 percent of the articles appearing focus on the use of AWB to produce renewable energy [31,37,44,45,174] (Figure 11).…”

Bioenergy from biofuel residues and waste

“…Cultivar M734 was estimated to yield the highest potential of total sugars (1557 kg/ha) and oil (663 kg/ha). Astolfi et al (2019) evaluated the use of cellulolytic enzymes produced from different agricultural residues. They were able to obtain maximum cellulolytic activities from using the hulls of soybeans.…”

Phytopathogenic Fungi: Useful Tools to Degrade Plant Biomass for Bioethanol Production

“…Residues from agriculture, forests and industries have highly increased with the expansion of the world population and studies stipulate that there will be around 8.5 billion of persons by 2030 in the planet, which could cause serious environmental and socioeconomic consequences [1]. However, agricultural by-products, which are lignocellulosic wastes, constitute promising renewable resources for bioethanol production since they are widely available and rich in polysaccharides as cellulose and hemicellulose [2]. The use of plant biomasses as renewable energy reduces environmental problems such as pollution and fires [1].…”
