Dust pollution and control with leather waste
- 89 Downloads
Dust is a serious worldwide pollution, notably for nanoscale particles that are both toxic and difficult to control. Dust suppression can be done by adsorption on solid wastes, such as collagen from by-products of leather manufacturing. Here we review dust pollution and dust control, notably using collagen degradation products. Simulation experiments show that dust suppression using modified collagen degradation products reaches 68.2% for particulate matter 2.5 (PM2.5) and 78.7% for particulate matter 10 (PM10). The advantages and disadvantages of the current dust suppressors are discussed.
