Green smart manufacturing can be considered as the integration of Industry 4.0 to achieve "smart" goals and implementing a circular economy to achieve "green" goals. In particular, green productivity and circular economy provide businesses with tools and methods to improve productivity, profits and overall growth with the least possible impact on the environment.

In addition, Industry 4.0 allows businesses' production activities to become intelligent, while meeting diverse market needs, optimizing resource use, building smart supply chains, reducing costs, minimize hazards and automate operations.

The main purpose of Industry 4.0 is to create value by integrating resources, services, data and people together. Manufacturers are starting to approach smart manufacturing, so Industry 4.0 will be a great assistant for information sharing, allowing transparency and visualization of production processes. In addition, manufacturers can ask customers to share market needs through market analysis technologies. A good information sharing system will improve the implementation of raw material management to reduce waste of environmental resources.
