I am a mechanical and environmental engineer, and I help companies pollute less by making a more efficient use of energy, water, materials and chemicals in their operations. When I started doing this, 15+ years ago, it was called pollution prevention or cleaner production, but now it has been rebranded as sustainability. Whatever the name of the practice, it is a pretty good idea to tread lightly on our resources by doing more with less.
