In both the materials used and the construction process, sustainability and efficiency will become standard. Improvements mjob site management and building design will reduce waste and cost of construction. Materials such as engineered wood, recycled carpeting, and cellulose insulation, which have lower environmental impact, will become cheaper and more widely available. Not only are buildings constructed with such material friendlier to the environment, they also provide higher-quality, lower-cost solutions. 

Cost breakdown of a high production mold or die is approximately as follows Material cost used to about 12 to 20%, design about 5 to 10%, mold building hours about 40 to 60%, and profit at about 5 to 10%. In general they are very expensive with the major cost principally in machine building labor. The proper choice of materials of construction for their different parts is paramount to quality, performance, and longevity of a mold/die. Add good machinability of component metal parts, material which will accept the desired finish (polished, textured, etc.), ability to transfer heat rapidly and evenly, capability of sustained production without constant maintenance, etc. 

Unlike the majority of bulk chemicals, most pharmaceuticals are very complex organic molecules that have to be constructed using multiple synthetic steps, often involving the isolation and purification of intermediate products. As a consequence, process efficiency has historically been very low [28]. In recent years, driven by both cost and sustainability issues, the research pharmaceutical companies have become industry leaders in the introduction of Green Chemistry and technology techniques into their process design. The implementation of environmental legislation such as this directive provides a further stimulus.
