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 efficiency 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.
循环经济旨在减少世界范围内产生的废物量，并将其转化为资源。循环经济指标的概念是为了评估在减少、再利用和回收校园废物方面取得的效率提高，该指标针对的是多哥洛美大学（University of Lome）校园内产生的废物。这些指标表明，2018 年校园内产生的 59.5%的废物可以通过堆肥引入循环经济模式，27.0%的能源消耗可以用沼气产生的清洁能源代替。整个塑料部分可以通过重复使用塑料瓶并将其余部分在城市港口出售引入循环经济模式。因此，2018 年每天可获得 15.5 欧元，到 2027 年每天可获得 34.5 欧元。至于旧轮胎，可以用目前存在于那里的轮胎产生的废物来代替校园内全部道路所需橡胶的 1.5%。因此，这些指标可以控制校园内的废物管理，并可以作为该国其他地区的一个模式。
