Road Sweepers for Hazards on Street - Waste and Recycling - Hazardous Waste
Several studies made by the Environmental Protection Agency, USA shows that the dirt on the road is just not normal soil but contains hazardous heavy metals. Recent studies have shown that more than 50% of heavy metals and other serious pollutants are attached to particles which measure 60 microns in size and smaller.
It has been confirmed that even though a street may look clean, there may still be a significant loading of small micron, pollution-laden debris on it. Additionally, from an environmental standpoint, it is exactly this formerly inconsequential material which is now considered most important to remove. The increased emphasis, by the EPA and others, is now being placed upon the removal of small micron debris.
