Around the world communities are discovering that Per- and Polyfluoroalkyl Substances or PFAS are commonly found in the environment. Scientific studies have linked exposure to PFAS to various adverse health effects, including altered metabolism, infertility, reduced fetal growth, disruption of hormonal and immune systems. There are several ways people can be exposed to PFAS including ingesting con ...

Repeated use of aqueous firefighting foams containing per- and polyfluoroalkyl substances (PFAS) has contaminated hundreds of sites. To delineate the extent of contamination, many of these sites are undergoing intensive site investigations and generating large quantities of investigation derived wastes (IDW). Current disposal practices of landfilling or incineration are costly and burdensome. This ...

Inerting, the process of suppressing oxidation ensures the freshness of food while retaining its nutrients and taste, extends the shelf-life of foods by up to eight times longer than other refrigerators. Xergy is proposing a low-cost, compact, simple to integrate and novel solid-state method of oxygen control based on an alkaline exchange membrane (AEM) electrolysis cell, a derivative technology f ...

The 1990 Federal Clean Air Act mandated the incorporation of oxygenates into gasoline in ozone and carbon monoxide nonattainment areas. Methyl tertiary butyl ether (MTBE) is the oxygenate of choice due to economic and supply considerations. Despite federal and state programs to improve handling of gasoline and other fuels in pipelines, underground and above-ground storage tanks, and other transpor ...

A novel combination of technologies is proposed by Montec Research to improve ex situ mercury remediation. The combination of acoustic agitation, iodine leaching chemistry, and real-time management of leach oxidation potential will allow mercury to be extracted economically from soils, sediments, and debris. Additional residue-washing steps are proposed to help residues pass the Universal Treatmen ...

The Phase I objective is to demonstrate the feasibility of applying recently developed enhanced ammoniacal leaching techniques and solvent extraction reagents to recycle nickel, copper, cobalt, zinc, and cadmium from hydroxide sludges such as those produced by electroplating shops, metal finishers, treatment of acid mine drainage, and industrial wastewater in general. Electroplating sludges, class ...

Sandhill Industries, a woman-owned small business and manufacturer of glass wall and floor tile, has developed a process for manufacturing paving products made from 99 percent recycled soda-lime plate or container glass. The glass pavers are thinner, lighter, denser, stronger, and perform better in paving applications than brick or concrete. Furthermore, the manufacture of the glass pavers generat ...

Lean burn spark engines are a promising technique to further reduce both NOx and hydrocarbon/carbon monoxide (HC/CO) engine emissions. Higher lean burn levels improve HC/CO oxidation while simultaneously reducing NOx formation. The NOx reduction is due to cooler flame temperatures. While the lean burn limit (beyond which combustion is poor) restricts further emission reductions, the use of oxyg ...
