Experienced engineers usually prefer the tried and tested methods, rather than possibly more exciting but untried novel designs. The work that is required to develop new processes, and the cost, are usually underestimated. Commercialization of new technology is difficult and expensive and few companies...
the chemical engineering scope has never been higher. the world awaits chemical engineers who can bring forth new environment-friendly materials which reduce the impact of our actions on our planet. also, there is always that race going on to improve the standard of living and technological innova...
Environmental engineers look for solutions to environmental issues, such as waste disposal, recycling, and pollution. They perform tests and quality checks for compliance and regulation adherence. They also develop processes and procedures for organizations that could impact the environment. Field service ...
