| Summary: | This research provides an analysis of existing scientific production on agricultural waste
from 1931 to 2018. The database was obtained from Scopus and includes a total of 3148
articles, which were analysed using the bibliometric method. This method focuses on the
identification, evolution, approaches and trends referred to in the use and transformation
of agricultural waste. The results of the analysis of the most specific variables, some of
which are represented graphically through clusters in networking maps using VOSviewer
software, establishes that agricultural waste has been studied worldwide for more than 60
years and that research on this issue has become more relevant from 1998. However, it has
been in the last 13 years that more than 60% of the scientific production on this field of
study has been generated. The United States, India and China are the countries with the
greatest number of studies, whose central axis has been the use and exploitation of
agricultural residues, derived from cereal crops, mainly wheat and corn, as they are the
main producers of this type of crops. Many authors, mainly from government and academic institutions, have contributed considerably to this research topic. The evolution of
their studies evidences a change in the original approach, due to the influence of the new
global energy and environmental policies developed during the last decade. Undoubtedly,
the international regulatory framework on sustainable development has been transforming the role of agriculture and especially the policies and strategies on the circular
economy and bioeconomy. New and better techniques for the recovery of agricultural
waste have been developed, based on industrial innovation and high technology, which
has contributed to guaranteeing resource efficiency, sustainable production and consumption and the reduction of negative environmental impact.
