Industrial ecology and some implications for rural SMEs

Abstract

In a project at Western Norway Research Institute, the concept of industrial ecology (IE) is used as a framework for environmental performance of small‐ and medium sized enterprises (SMEs) in Norway. The main goal of the project ‘Green SMEs’ is to identify existing and future environmental challenges for rural SMEs. The focus is on external demands coming from the surroundings of the individual businesses. Examples of issues being dealt with are industrial wastes becoming sources of raw materials for other industries, design and material choice for disassembly and reuse, development of industrial ecosystems, and industrial metabolism. This paper presents actual examples of industrial ecosystems and also some cases illustrating the problems small remotely located firms meet when the principles of IE are to be applied. These problems include the inability to participate in efficient industrial ecosystems (webs) with exchange of wastes to raw materials. Larger companies, often being more centrally located, have greater chances at identifying and attracting other businesses which they can co‒operate with in finding usage for their wastes. The ‘cluster’‒properties of efficient industrial ecosystems can therefore be a limiting factor in the development of such systems in rural areas. Small companies also have less opportunities to be proactive in establishing industrial ecosystems also merely due to the smaller scale of their operations. © 1997 John Wiley & Sons, Ltd. and ERP Environment.

Using Life Cycle Assessment (LCA) to measure the environmental benefits of industrial symbiosis in an industrial cluster of SMEs

“…This study assesses the life cycle environmental benefits of the IS initiatives implemented in the industrial cluster of small and medium enterprises (SMEs) of S.Croce sull'Arno (Italy). Previous studies have highlighted how SMEs face barriers in the adoption of these initiatives (Andersen, 1997). Following Chertow's definition (see Sect.…”

Environmental management practices among hotels in the greater Accra region

“…Alvarez Gil and Cespedes Lorente (2001) are of the view that large firms are exposed to considerable environmental pressure from stakeholders because: their environmental impact is more visible; it is easier to control centralized sources of pollution than dispersed units and large firms are regarded as industry leaders and thus constitute models to imitate. Also, large firms have economies of scale in the reuse, recycling or valuation of waste (Andersen, 1997). Looking at the relationship between environmental management and chain affiliation, Alvarez Gil and Cespedes Lorente (2001) are of the view that the functions carried out by hotel chains that refer to transfer of knowledge are extremely important for environmental protectionrelated matters.…”

Environmental strategies in spanish hotels: contextual factors and performance

“…Likewise, other theoretical arguments that have been used to justify why large firms develop a more advanced environmental management point out that: (1) they have a greater availability of resources to invest in environmental protection [Sharma and Vredenburg, 1998]; (2) large firms usually adopt a more formal management and this would be extended to a more formal environmental management [Merritt, 1998]; (3) they may have economies of scale for the re-use, recycling or valuation of waste [Andersen, 1997]. For all these reasons, we can expect that large hotels will be more encouraged to adopt environmental proactive strategies than small ones.…”
