Control Methods for Odor and Dust in MRFs

In many ways, material recovery facilities (MRFs) are harsher work environments than landfill working faces. During both operations, the protection of human health and the environment are primary concerns. While not exposed to the elements, the management of waste in a confined building has its own hazards. Enclosed facilities that

Pierce County’s Surface Water Management (SWM) division is charged with maintaining both the natural surface water systems and the stormwater collection and conveyance infrastructure within its unincorporated 1,800-square-mile service area (population 380,000). These areas include an impressive variability in landscapes: from glacial streams of Mt. Rainier to fertile farmlands of

STORMCHAMBERS
HydroLogic Solution’s StormChamber systems are highly cost effective for control of stormwater runoff, peak flow attenuation, sediment control, nutrient and pollutant removal, and stormwater conveyance. One row of 34-inch StormChambers provides conveyance capacity approximately equivalent to 42-inch pipe; 52-inch pipe with our 44-inch StormChambers. StormChamber systems are less expensive, and

You might never look at gummy bears in the same way again. This summer, fishing crews all along the West Coast of the US and Canada are finding an abundance of pyrosomes—colonies of jelly-like sea creatures, or zooids—that have been compared, in texture and appearance, to the dense, transparent candy. Typically
