“…In this sense, interaction with other ecosystem actors is fundamental to CE implementation in SMEs. While the lack of supporting reference points and challenging B2B cooperation (Jaeger & Upadhyay, 2020; Rizos et al, 2016) may be barriers, networks are considered a valuable information source (Ostermann et al, 2021), and the existence of a fertile ecosystem, CE intermediaries for the implementation process, and stakeholder engagement may act as drivers for CE implementation in SMEs (Caldera et al, 2019; Torres‐Guevara et al, 2021). In the case of potentials for industrial symbiosis in SMEs, three groups of problems were identified; namely, organisational management, related to low IT assistance and lack of data reliability; waste management, related to the weak CE waste policy and poor waste‐to‐resource strategies; and resource management, related to low coordination and high centralisation of resources (Rincón‐Moreno et al, 2020).…”
