After the coal, oil, natural gas is no longer used as a fuel and a large number of synthetic materials mainly used as raw material, the supply of non-metallic materials are also available to ensure the long-term gas chemical engineering, metallurgical engineering and other production processes arising from waste water environmental pollution, by improving processes, increasing purification machinery and equipment and improve its purification efficiency, is technically capable of being eliminated.
Mechanical engineering has always been to increase production, improve labor productivity, improve the economics of production, namely to increase the interest of mankind as the goal to research and development of new mechanical devices

Mechanical engineering has always been to increase production, improve labor productivity, improve the economics of production, namely to increase the interest of mankind as the goal to research and develop new machinery products. In the coming era, the development of new products will reduce resource consumption, the development of clean and renewable energy, governance, reduce environmental pollution as well as the elimination of extra-economic objectives and tasks of mechanical engineering is the traditional engineering techniques. Machinery can be done with human hands and feet and eyes and ears done directly can not directly work done, and done faster and better. Modern mechanical engineering to create more and more sophisticated and more complex machinery and mechanical devices
