“…The sixth cluster, identified in yellow, is made up of a total of six authors. Two of the investigations carried out by this collaborative group are "Gasification biochar from horticultural waste: An exemplar of the circular economy in Singapore" and "Closing the food waste loop: Food waste anaerobic digestate as fertilizer for the cultivation of the leafy vegetable, xiao bai cai (Brassica rapa)" [67,68], which have the collaboration of Yen Wah Tong, Hugh TWTan, and Ee Yang Lim. Finally, the sixth cluster is identified in dark blue and records numerous investigations on CE applied to agriculture [69,70].…”

In this current and global context led by scarcity of resources, environmental degradation, global climate change, and a progressive demand for food, the circular economy (CE) represents a key economic model or framework for sustainable, restorative, and regenerative agriculture. Hence, CE applied to agriculture seeks to close the life cycle of products, services, waste, water, and energy to obtain a better use of resources and a reduction of the ecological impact. An initial review of the literature corroborates the hypothesis that the CE framework has not yet been comprehensively adapted to the field of agriculture. This research seeks to overcome this gap in relation to the performance of the circularity of agricultural production systems in support of decision-making processes. A bibliometric analysis of 1060 documents was carried to synthesize the knowledge base on this topic. The results show recent studies that identify weaknesses derived from food production, such as waste generation, biomass, water pollution, and greenhouse gas emissions. It has been identified how their analysis has developed to date and what terms allow us to visualize new approaches; consequently, it is a useful tool for researchers and sponsors who provide financial resources for the development of new lines of research.

“…180,181 Likewise, a previous study 182 documented the potential of carrot peel waste for the bioconversion of pectin and carotene through advanced biorefinery approaches. In addition, another study 183 demonstrated the conversion of greenhouse horticultural waste into value-added products through bioconversion and biorefinery approaches. These approaches can effectively valorize the unavoidable yet potential food waste and waste streams through the concept of bioeconomy.…”

“…99 The competitiveness of the gasification process over the other technologies is due to its low cost. 100 Moreover, this strategy was also discovered to be more viable for disposing of food waste and creating renewable energy using waste. 101 Despite its several advantages, one of the primary drawbacks was that the biochar generated frequently contained certain harmful substances, such as chemical compounds and polyaromatic hydrocarbons, making environmental mitigation more challenging.…”

Among the feasible options for valorizing lignocellulosic biomass into value‐added products, biochar is considered to be extremely appealing and it could be applied easily in several established thermochemical processes. Biochar possesses a large surface area due to its porous nature, which permits easy use in various applications, including catalytic biofuel production. This work summarizes research on biochar generation processes, its critical physicochemical properties, and factors that influence them. Important studies adopting biochar catalysts for liquid biofuel production are critically reviewed, and the reaction mechanisms and biofuel yield are analyzed. Finally, challenges in the use of biochar‐based catalysts for biofuel production are presented, together with possible solutions. In general, this current work aims to provide the critical characteristics of biochar as a potential catalyst to biofuel synthesis toward sustainable bioenergy production.
