“…According to Vives [2006], the disseminating of the CP concept among SMEs is constrained by a lack of resources, lack of knowledge, and the perception of SMEs that CP didn't have an impact on the environment. Other studies showed that the disseminating of the CP concept among SMEs is constrained by these factors: a lack of vision and knowledge on the part of business managers [Baas, 2007], [Studer , et al 2005], [Hilson, Nayee, 2002]; lack of internal resources such as investment capital [Mitchell, 2006], [Hitchens, et al 2003], [Frijns, van Vliet, 1999]; limited technical know-how and information about viable cleaner practices and technologies [van Berkel, 2007], [Grutter, Egler, 2004], [ Hilson, 2000]; little staff motivation for development and implementation of CP alternatives [Baas, 2006], [Stone, 2006]; and lack of availability of tailor-made tools and strategies for environmental improvement in SMEs [Jenkins, 2004]. Although there are a number of constraints in disseminating CP concepts among SMEs, a study conducted by Rahman, et al [2009] found that CP activities provide environmental improvement and it contributes to competitive advantage in Indonesian SMEs.…”
