“…In the case of environmental science, the terms of sustainable development and agroecology are framed among other concepts since the purpose of this field of study is to ensure a sustainable future [13,72,73]. On the other hand, the terms energy and engineering are related to the search for actions that optimize waste management processes [84][85][86]. Therefore, both subject areas represent the terms of agricultural robots or nutrient recovery.…”

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.

A growing global population and climate change threaten the availability of many critical resources, and they are directly impacting the food and agriculture sector. Therefore, new cultivation technologies must be rapidly adopted and implemented to secure the world’s food needs. Closed-loop greenhouse agriculture systems provide an opportunity to decrease resource reliance and increase crop yield. Greenhouses provide versatility in what can be grown and the resources required to function. Greenhouses can become highly efficient and resilient through the application of a closed-loop systems approach that prioritizes repurposing, reusing, and recirculating resources. Here, we employ a text mining approach to research the available research (meta-research) and publications within the area of closed-loop systems in greenhouses. This meta-research provides a clearer definition of the term closed-loop system within the context of greenhouses, as the term was previously vaguely defined. Using the meta-research approach, we identify six major existing research topic areas in closed-loop agriculture systems, which include models and controls, food waste, nutrient systems, growing media, heating and energy. Furthermore, we identify four areas that require further urgent work, which include the establishment of better connection between academic research to industry applications, clearer criteria surrounding growing media selection, critical operational requirements of a closed-loop system, and the functionality and synergy between the many modules that comprise a closed-loop greenhouse system.

“…By applying appropriate practices, such as a circular economy approach to organic food waste, there is an opportunity to generate revenue, reduce waste management issues, and bolster the economy (Rashid and Shahzad, 2021). However, the level of understanding regarding the advantages of adopting closed-loop technologies for organic waste varies by country and poses a challenge (van der Velden et al, 2022).…”

The growing global population and climate change threaten the availability of many critical resources, and have been directly impacting the food and agriculture sector. Therefore, new cultivation technologies must be rapidly developed and implemented to secure the world's future food needs. Closed-loop greenhouse agriculture systems provide an opportunity to decrease resource reliance and increase crop yield. Greenhouses provide versatility in what can be grown and the resources required to function. Greenhouses can become highly efficient and resilient through the application of a closed-loop systems approach that prioritizes repurposing, reusing, and recirculating resources. Here, we employ a text mining approach to research the available research (meta-research) and publications within the area of closed-loop systems in greenhouses. This meta-research provides a clearer definition of the term “closed-loop system” within the context of greenhouses, as the term was previously vaguely defined. Using this meta-research approach, we identify six major existing research topic areas in closed-loop agriculture systems, which include: models and controls; food waste; nutrient systems; growing media; heating; and energy. Furthermore, we identify four areas that require further urgent work, which include the establishment of better connection between academic research to industry applications; clearer criteria surrounding growing media selection; critical operational requirements of a closed-loop system; and the functionality and synergy between the many modules that comprise a closed-loop greenhouse systems.
