Several major automakers are betting on hydrogen-powered cars as the future of personal transportation. The first of these cars are already available in California. What isn’t readily available is the hydrogen to power them. There are very few hydrogen stations out there and hydrogen is pretty expensive.
Our nation’s landfills are overflowing and we are constantly seeking ways to reduce the amount of waste that needs to go into them. Usually, we are thinking about food waste, plastics, glass and paper. However, one of the largest sources of waste generation is actually construction and demolition waste. Estimates are that between 25 and 40% of the national solid waste stream comes from these activities and very little of it gets recycled.
