Technologies used in enabling effective CE

TechnologiesTechnologies used in enabling effective CE
Internet of things (IoTs)IoT technologies can help reduce waste and improve food safety, as well as increase the overall efficiency and sustainability of the food supply chain (Ben Daya et al., 2019)
Machine learningMachine learning has been used to help reduce greenhouse gas emissions and to promote environmental and social concerns (Liu et al., 2020)
Circular integrated waste management systems (CIWMS)CIWMS have been used to promote sustainability by increasing the link between resource disposal and recycling (Cobo et al., 2018)
3D printingTo produce high-quality consumer goods such as camera tripods, SD card holders and camera covers, plastic waste from computer debris is transformed into 3D printed filaments, thus shortening the CE cycle (Zhong and Pearce, 2018)
Waste electrical and electronic equipment (WEEE)WEEE can be used to integrate waste and product lifecycle management, making cities more sustainable and smarter by using the internet of Things (Esmaeilian et al., 2018). To improve the WEEE recycling process, collaborative robots could be introduced into a processing line that would work alongside humans to increase the number of valuable parts recycled (Alvarez-de-los-Mozos and Renteria, 2017)
Radio frequency identification (RFID)RFID technology is an effective way to improve product quality assurance and safety by identifying batch dates and times as well as identifying individual products (Verdouw et al., 2016). Environmental factors such as weather, humidity and nutritional parameters can be assessed using this tool
