Abstract

Ecomaterials were categorized based on their life cycle and eco-efficiency. Taking ecomaterials in their broadest sense, as “materials for the environment”, there are “function materials for environmental protection” and “materials for advanced energy systems”. These materials improve services such as maintaining the living environment, or rendering energy. “Materials of life-cycle design” which are ecomaterials in the strict sense, are characterized by the stages in life-cycle where the focus of reduction of the environmental burden is given to: “materials with a green environmental profile”, “materials of higher material efficiency”, “materials of higher recyclability”, “materials of hazardous substance free”. On the basis of this classification, the present state of Website home pages and commercialized ecomaterial described in the environmental report book of the enterprise was investigated. There were many “materials of higher material efficiency” and “materials of hazardous substance free”, and these were respectively 39%, and 31% of the total. “Materials of green environmental profile” composed 21%, and “materials of higher recyclability” gleamed 5%. The “materials of life-cycle design” are obviously well represented in the market, appealing as they do to the consumer.
