Answer: Green technology is a technology in which sustainability is a goal. This means that when the technology was developed and is now being used it serves the purpose of accomplishing something either common (like for instance industrial waste water treatment) or specifically developed in order to “green” something. Green technologies are growing in more popularity every year. A teacher of mine from a few years ago developed his own type of green technology when he worked with an industrial plant treating their waste water. Here he developed a way to remove mercury from the water to a very high percentage however he also managed to do so in a way that the mercury could be reused. Therefore eliminating the need to continuously be using mercury at the plant-the amount they had was sustainable for their operations.
