Abstract

VAN ZYL, M.  and  VAN EEDEN, J.. A circular economy investigation into treatment technologies available for the disposal of slaughterhouse derivatives. S. Afr. J. Ind. Eng. [online]. 2022, vol.33, n.3, pp.150-168. ISSN 2224-7890.  http://dx.doi.org/10.7166/33-3-2791.

Two major problems challenge the world of food today: the constantly growing demand for meat products and dealing with the volumes of waste produced by the industry. The volume of slaughterhouse derivatives produced when generating meat products threatens the health of humans and the environment. The need to feed a growing population sustainably and to find more sustainable and circular alternative treatment technologies for handling and disposing of slaughtering derivatives undoubtedly creates opportunities for several role players. A comprehensive bibliometric analysis was undertaken to identify such processes, considering the different slaughterhouse derivatives generated by red meat and poultry slaughterhouse facilities. The literature search and refinement process identified 130 scientific documents for analysis. The results highlight an increase in the scientific literature on the sustainable recovery of slaughterhouse derivatives, and a diverse range of available treatment technologies to dispose of such derivatives.
