Conclusion
There are many challenges of chemical
engineering, humans will benefit in overcoming these challenges. Developing chemical engineering is very important for humans ,but people should do it without pollution of environment.
Restore and Improve Urban Infrastructure
The infrastructure of large cities, including utilities, transportation systems, telecommunications stems, healthcare systems, and the like, affect quality of life and need significant improvement in most cities of the world. Chemical engineers can play a role in some aspects of this challenge, including in the improvement of water-treatment systems and power plants and the reduction of automobile pollution.
Introduction
The list of challenges was directed to all engineering disciplines, but chemical engineering is uniquely positioned to play a leadership role in many of them. In other words, chemical engineers can help humankind in general and can impact our whole earth! Here are the Grand Challenges
Provide Access to Clean Water
The lack of clean drinking water directly or indirectly causes millions of deaths worldwide and is today’s greatest health hazard. Chemical engineers will continue to play a critical role in developing better and less-expensive methods for removing microbes and toxins from water and for removing salt from sea water.

Make solar Energy Economical
Chemical engineers can help develop new materials with unique chemical/electrical properties that will help reduce the cost and increase the efficiency of solar collectors and to create battery systems to store electrical energy from solar systems. Provide Energy from Fusion Fusion, which produces the energy of the sun, clean energy on Earth if it can be harnessed. Chemical engineers can help to discover and design the conditions and materials needed to induce fusion reactions and the reactors needed to contain those reactions.

Reverse-Engineer the Brain
This grand challenge is based on the notion that knowledge of the information patterns of the brain (information sharing, parallel processing, etc.) could provide a key to more effective diagnosis and treatment of neurological diseases and could also be utilized to formulate more effective decision-making strategies in our technical world. Chemical engineers are well equipped to join with others in this effort. Prevent Nuclear Terror Methods are needed to thwart possible terrorist attacks using nuclear weapons constructed from waste material stolen from nuclear reactors and shipped into our country hidden in the vast volume of our imports. Needed are devices to track nuclear material in reactors and post-reaction facilities to detect its unlawful removal, and devices to more effectively detect such material in shipping containers. Chemical engineers will contribute to these developments.
Secure Cyberspace
Improved methods of security are needed to thwart possible cyber attack on our computer-based society. Needed are more rigorous authentication of users, protection of data during transfer, and countermeasures. Chemical engineers generally play a peripheral role in such work, but a few typically build upon their versatile foundation to focus on computer technology. Engineer the Tools of Scientific Discovery Future technological achievement will require more advanced, yet cheaper, analytical instruments and methods adaptable to research environments ranging from biological field studies to advanced laboratories to space stations. Chemical engineering, with its broad encompassing of chemistry, math, physics, and biology, will continue to play a leadership role in this innovation.

Advance Health Infrastructure Grand Challenges
Develop Carbon Sequestration Methods
The concern that rising levels of carbon dioxide – which can trap heat like a “greenhouse” – in our atmosphere may be promoting warming of the earth has led to efforts to capture or “sequester” carbon dioxide produced by the burning of fuels and to convert it to useful products or store it, for example in the earth. Chemical engineers can help develop these chemical processes. Advance Health Informatics Health informatics involves the collection and maintenance of health information in order to enhance quality of life through improved medical care. This area, however, involves much more than health records! Imagine if health data could be gathered continuously by means of tiny sensors embedded in clothing or within the body. Chemical engineers will play a critical role in the development of such technology. Chemical engineers
