Wood chips beat water in 1979 coal road dust control
Original: In 1979, wood chips covered a U.S. coal-haul road and made dust control last 10 times longer than water s
A 1979 trial in the United States found that covering a coal-haul road with wood chips kept dust suppression effective roughly ten times longer than standard water spraying. The decades-old result is being recirculated now, drawing attention as a low-cost, low-tech dust control method with possible relevance to modern road management and environmental practice.
Why now: People are sharing the striking finding that a simple wood-chip treatment dramatically outperformed water spraying, with fresh relevance amid interest in cheap dust and emissions control.
