1979 wood chip road experiment cut coal dust tenfold
Original: In 1979, wood chips covered a U.S. coal-haul road and made dust control last 10 times longer than water s
In 1979, a United States coal-haul road was treated with wood chips instead of water, and the dust control lasted about ten times longer. The little-known case is being shared as an example of how simple, low-cost materials can solve industrial dust problems, prompting comparisons with modern dust-suppression methods used in mining and construction.
Why now: People are discussing it as a retro engineering solution that still outperforms common water-based dust control.
