Evaluation of Hard Materials Using Eco-Attributes Md.
Eco-attributes of some selected hard materials.
Categories of hard materials in terms of eco-attributes.
Categories Reasons Position of Hard Materials used in this study (based on the results in Figs. 3-4) A Close to idea materials Alumina based hard materials B Some cases close to ideal materials some cases not Zirconia based hard materials Silicon Carbide based hard materials C Relatively far from ideal materials Boron Nitride based hard materials D Mostly far from the ideal materials Boron Carbide based hard materials Sensitivity Analysis An obvious question is that, what if the membership functions of the linguistic classes (fuzzy numbers) in Table 1 are defined differently?
The environmental impact of Boron Nitride based materials remains between that of Zirconia and Boron Nitride based materials

Materials efficiency is therefore the ratio of output of products and goods to input of raw materials.
The materials with the highest consumption rate are construction materials (sand, gravel, stones and cement).
A jury with experts from science and economy selected the best-practice examples of an economically profitable increase of materials efficiency by using innovative applications.
