The resource basis of industrial energy production is still, to a large extent, in non-renewable fossil fuels, the use of which creates emissions that the ecosystem has difficulty in tolerating. The goal of industrial ecology is to substitute the non-renewable stocks with renewable flows. In this paper, a regional industrial ecosystem that relies on a power plant as its key organisation, as an anchor tenant, is considered in the context of energy production and consumption. The co-production method of heat and electricity (CHP, co-production of heat and power) is implemented in the local power plant. This method uses the waste energy from electricity production for district heat and industrial heat/steam. The fuel basis in a CHP plant can include heterogeneous waste fuels. The method has been applied, to a large extent, in only three countries in the world; Denmark, The Netherlands and Finland. Examples of CHP-based industrial ecosystems from Finland are considered. CHP is reflected upon from the viewpoint of industrial ecosystem principles. 相似文献
