“…The development of innovations that combine agriculture with biotechnology enables the production of high potential bioproducts such as enzymes, organic acids, bioethanol, and biopesticides, as well as energy generation. Indeed, the management of agroindustrial waste and its practical application are critical to the circular economy's development (Leong et al, 2021;Lachos-Perez et al, 2022;Yaashikaa et al, 2022).…”

Eco-innovations that reduce the environmental effect of manufacturing and consumption are seen as critical components of sustainable development and a critical component of the transition to a circular economy. Food systems address the issue of food waste, which is generally acknowledged as a cost to the economy, the environment, and society. Eco-innovations seem to be critical for the food system's transformation to a more circular model centered on sustainable food production and processing. The goal of this paper was to determine the variables that influenced the introduction of product, process, organizational, and marketing innovations in European Union agri-food enterprises between 2012 and 2014. According to a preliminary analysis of the data, 57.40% of agribusinesses did not implement any form of innovation, which prompted the authors to study the difficulties surrounding innovation development over the 3-year reference period. Several key factors emerge as significant influences on the introduction of product innovations (0.055**); contractual requirements as significant influences on the introduction of process innovations (−0.081***); and environmental incentives as significant influences on the introduction of marketing innovations (0.062***). Additionally, product (0.704***) and process (1.051***) innovations tend to have a greater influence on enterprises' views of circular benefits. The investigation also demonstrates how enterprises and end users interpret the effect of various forms of innovation differently. Indeed, end users, in contrast to how enterprises understand it, believe that organizational (0.611***) and marketing (0.916***) innovations are critical in pursuing circular benefits.

“…Pant et al [ 21 ] formulated research on the present growth of the bio-based economy among European countries and India. Yaashikaa et al [ 22 ] discussed various sources of agro-industrial waste and different methodologies for its valorization along with life cycle analysis in agricultural circular bioeconomy. Technological improvements in bioethanol production along with its blending mandates and policies worldwide were reviewed by Raj et al [ 23 ].…”

Lignocellulosic Biomass Valorization for Bioethanol Production: a Circular Bioeconomy Approach

et al. 2022

View full text Add to dashboard Cite

Lignocellulosic biomass generated from different sectors (agriculture, forestry, industrial) act as biorefinery precursor for production of second-generation (2G) bioethanol and other biochemicals. The integration of various conversion techniques on a single platform under biorefinery approach for production of biofuel and industrially important chemicals from LCB is gaining interest worldwide. The waste generated on utilization of bio-resources is almost negligible or zero in a biorefinery along with reduced greenhouse gas emissions, which supports the circular bioeconomy concept. The economic viability of a lignocellulosic biorefinery depends upon the efficient utilization of three major components of LCB—cellulose, hemicellulose and lignin. The heterogeneous structure and recalcitrant nature of LCB is main obstacle in its valorization into bioethanol and other value-added products. The success of bioconversion process depends upon methods used during pre-treatment, hydrolysis and fermentation processes. The cost involved in each step of the bioconversion process affects the viability of cellulosic ethanol. The lignocellulose biorefinery has ample scope, but much-focused research is required to fully utilize major parts of lignocellulosic biomass with zero wastage. The present review entails lignocellulosic biomass valorization for ethanol production, along with different steps involved in its production. Various value-added products produced from LCB components were also discussed. Recent technological advances and significant challenges in bioethanol production are also highlighted in addition to future perspectives. Graphical abstract

“…On similar lines, these agro-industrial residues have been found to be suitable as nutrient supports for the growth of microorganisms and produce pigments by both submerged and solid-state fermentation (SSF). This approach not only combats environmental problems but also provides a sustainable and cost-effective framework for developing the circular bioeconomy ( Banu et al, 2021 ; Muscat et al, 2021 ; Yaashikaa et al, 2022 ).…”
