The circular economy aims to reduce the volume of waste generated in the world,
transforming it into resources. The concept of indicator of circular economy was introduced to
evaluate the improvement obtained regarding e ciency in terms of reduction, reuse and recycling of
waste generated on the campus of the University of Lome (Togo). These indicators showed that 59.5%
of the waste generated on the campus in 2018 could be introduced into the circular economy paradigm
through composting, and 27.0% of the energy consumed could be replaced by clean energy obtained
from biogas. The entire plastic fraction can be introduced into the circular economy paradigm by
reusing plastic bottles and selling the rest in the port of the city. Thus, the income obtained could
range from €15.5/day in 2018 to €34.5/day in 2027. Concerning old tires, 1.5% of the rubber needed to
pave the entire roadway of the campus could be replaced by the waste generated by the tires currently
existing there. Consequently, waste management on the campus could be controlled thanks to these
indicators, and this could serve as a model for the rest of the country.Research Project ECO2017-84138-P MINECO, AGENCIA ESTATAL DE INVESTIGACIÓN and
