“…According to Kardung et al [20], a new term "circular bioeconomy" has been introduced, combining the concepts of bioeconomy and circular economy and highlighting the use of a circular approach to the bioeconomy while showing overlap limitation. The importance of our research keywords "manure" and "biorefinery" is strengthened with the study of Khoshnevisan et al [27], about livestock manure management technologies. They are suggesting the necessity of forming a sustainable circle where manure management enters into the biorefinery concept integrating with manure nutrient recycling.…”

Bioeconomy and Livestock Production Nexus: A Bibliometric Network Analysis

Over the last couple of decades, the livestock production systems of the agri-food sector increase meat production in order to meet the demand and adapt to satisfy the food preferences of the continuously increasingly world population. This fact, along with the promotion of sustainable production, has brought to light the topic of bioeconomy. The rapid increase in publications on the research area of bioeconomy has become the motivation for this study in order to analyze its relation with livestock production. This study provides a thorough review of the scientific literature on the bioeconomy of livestock production. The bibliometric network analysis (i.e., software VOSviewer) were performed over the time frame of 2004–2021. The results identified 624 documents bioeconomy of livestock production by 160 research organizations from 83 countries. This paper visualizes the strongest links about livestock production bioeconomy, main research topics, most influential countries, authors, and organizations, as well as high-frequency keywords. Therefore, this study contributes to building global bioeconomy policies and encouraging the livestock sector to implement bioeconomy practices. The research gap identified in many countries should be the trigger for future research in this subject.

“…Part of the animal feed manifests as manure which again is a biorefinery input. It yields biogas when the solid fraction is digested anaerobically, and bio-oil, when the liquid portion is subjected to hydrothermal liquefaction [138]. While scenarios with bioenergy production were shown to rank higher on a scale of environmental sustainability in [110], the profitability, intuitively, will be greater if the wastes are valorised to bio-chemicals and biopolymers [284].…”

While ‘renewable’ is the keyword in a bioeconomy and resource conservation is the motivation behind a circular economy, a circular bioeconomy is one in which waste streams from renewable bio-resources are looped back into the technosphere—open-loop or closed-loop recycling or conversion from matter to energy. This systematic review brings together 385 publications from 2015 to 2021, originating from 50 countries and appearing in 150 journals, into a coherent account of the status quo of published research on circular bioeconomy. The numbers bear testimony to the growing interest in this field of research. Germany is the leading contributor to the scientific literature base (10%), while the Journal of Cleaner Production (9%) tops the list of journals in the fray. The methodology adopted has been clearly explained, and the discussion has been segmented into sub-sections and sub-sub-sections to do justice to the diversity of the nature of the publications. A little flexibility in organisation of the flow of the text has been availed of, to improve readability. The circular bioeconomy can be visualised as a set of ‘many through many to many’ relationships, enabling both economies of scale and scope in the longer run. This calls for extensive collaboration and cooperation among the numerous stakeholders involved. Several barriers will have to be overcome. Technology impact assessments and sustainability risk appraisals need to be carried out in order to ensure and convince stakeholders that they are on the right path. But as one knows and will appreciate, challenges lurk where there exist opportunities to be availed of, to replace the take-make-use-dispose paradigm of a linear economy to the grow-make-use-restore alternative.

“…Among particles smaller than 10 μm for anaerobic digestates, there were no particles larger than 2 μm detected. This suggests that, if a microfiltration step is intended for digested swine manure, the removal of particles larger than 10 μm may be sufficient as a pretreatment [ 64 ].…”

Manure and digestate liquid fractions are nutrient-rich effluents that can be fractionated and concentrated using membranes. However, these membranes tend to foul due to organic matter, solids, colloids, and inorganic compounds including calcium, ammonium, sodium, sulfur, potassium, phosphorus, and magnesium contained in the feed. This review paper is intended as a theoretical and practical tool for the decision-making process during design of membrane-based systems aiming at processing manure liquid fractions. Firstly, this review paper gives an overview of the main physico-chemical characteristics of manure and digestates. Furthermore, solid-liquid separation technologies are described and the complexity of the physico-chemical variables affecting the separation process is discussed. The main factors influencing membrane fouling mechanisms, morphology and characteristics are described, as well as techniques covering membrane inspection and foulant analysis. Secondly, the effects of the feed characteristics, membrane operating conditions (pressure, cross-flow velocity, temperature), pH, flocculation-coagulation and membrane cleaning on fouling and membrane performance are presented. Finally, a summary of techniques for specific recovery of ammonia-nitrogen, phosphorus and removal of heavy metals for farm effluents is also presented.
