Refrigerants are known to have harmful impacts on the environment. It is essential that those that are particularly harmful with a high global warming potential (GWP) are recovered correctly for proper recycling or disposal. Unfortunately, all too often, refrigerant is not properly recovered either due to system failure, technician error, or unincentivized industry practice. With implementation of ...

Michigan Aerospace proposes to retrofit the Egret LIDAR technology to improve operation stormwater management infrastructure. The Egret LIDAR is a novel sensor that can monitor stormwater without submersion. Using LIDAR remote sensing, the Egret can measure turbidity, surface height, water depth, flow speed, and suspended particle sizes from above the water surface. The Egret measures water proper ...

Fats, oils and greases (FOGs) cause 75% of sewer systems in the US to operate at 50% capacity, cost US cities over $20 billion in sewer maintenance, and cause over 40,000 sewer overflows annually. Most commercial kitchens are required by law to remove FOGs with a grease interceptor from wastewater before emitting into public sewers. In order to reduce sewer maintenance costs and overflows while in ...

Taskforces, utilities, and manufacturers must adapt to contaminants of emerging concern. The most prevalent, persistent, and problematic of these pertinent pollutants are per- and polyfluoroalkyl substances (PFAS). Resource managers need reliable and resilient technologies that convert waste streams to value streams and satisfy regulations. Current state of practice for management of PFAS-laden so ...

This Small Business Innovation Research (SBIR) Phase II project will perform some needed tests for commercialization of the highly PFAS-selective nanofiber mats fabricated from electrospun polymer nanofibers. The Phase I results have shown the proof of concept for two materials developed for the removal of PFOA and PFOS with over 91% efficiency at very high concentrations (ppm level) and 99% at lo ...

We propose to develop an innovative, inexpensive process to destroy poly- and perfluoroalkyl substances (PFASs) and provide safe drinking water to millions of U.S. residents.Need. PFASs are highly resistant to breakdown in the environment and pose risks to developmental, immune, metabolic, and endocrine health. The drinking water supplies for millions of U.S. residents exceed the U.S. EPA’s life ...

Per- and Polyfluoroalkyl Substances (PF AS) have been widely used in everyday consumer products. Landfills are the final repository for the PF AS-containing products and wastes, and consequently, one of the major sources of PF AS to the environment. Elevated concentrations of PFAS in leachate have raised concerns regarding disposal of leachate. Yet, cost-effective treatment technologies for PF AS ...

In addressing Topic 1C in this solicitation, “Innovative pretreatment technologies for PFAS in industrial wastewater”, this Small Business Innovation Research (SBIR) Phase I project will develop a novel nanofiber mats fabricated by electrospun polymer nanofibers for the “smart” (selective) removal of perand polyfluoroalkyl substances (PFAS) from landfill leachate. The co-contaminants, low ...

Assessment of wild land fire smoke exposure is a genuine concern to fire managers, public health officials, air quality regulators, and the public. Exposure to vegetation fire smoke products poses acute and chronic health hazards to first line responders, firefighters, and to communities located downwind of their source. Current instrumentation capable of providing reliable air quality data is exp ...

This EPA SBIR Phase I Research and Development proposal will demonstrate feasibility of reduction in halogenated flame retardant use in polyisocyanurate foams prepared from lignincontent rPET polyols. The study will show whether or not the lignin rPET polyol formulations meet ASTM flame retardancy standards and thus reduce or eliminate the need for halogenated fire retardants (HFRs) in spray foams ...
