The Small and Mid-Size Farms topic area aims to promote and improve the sustainability and profitability of small and mid-size farms and ranches (where annual sales of agricultural products are less than $350,000 for small farms and between $350,000 and $999,999 for mid-size farms – hereafter referred to as small farms).

The objective of this topic area is to enhance crop production by creating and commercializing engineering technologies that enhance system efficiency and profitability and protect crops from pests and pathogens in economically and environmentally sound ways.

Zero-liquid discharge and brine concentrate minimization Treatment and destruction of PFAS in wastewater and other waste streams HABs sensors that can monitor cyanobacteria and toxins 1 EPA SBIR 2023-2024 Phase I Solicitation Environmental Protection Agen ...

Energy efficient and cost-effective technologies that can minimize or eliminate the liquid portion of brine concentrate and can therefore enable the treatment and potential use of different types of wastewater. Ideally technologies should recover water or even solids from these waste streams and create additional benefits to offset costs and enable additional water reuse and resource recovery. A ...

Technologies should be field deployable and should be able to remove or destroy PFAS in relevant waste streams including, but not limited to, leachate, wastewater, RO concentrates, ion exchange regenerant solutions, and spent activated carbon and ion exchange resins. Ideally, technologies could operate at flow rates appropriate to field application, and all residual or emission streams should be e ...

Technologies can be remote or in-situ, should be self-recharging and should include communication technology for real-time detection from remote locations that don’t have access to cellular signals. Technologies should be affordable and reliable and should ideally have the following characteristics: • Have the capability to detect chlorophyll a (a surrogate for phytoplankton biomass) and phyco ...

Ideally, technologies would significantly reduce indoor PM2.5 and other air pollutants (e.g., volatile organic compounds or VOCs), and maintain performance under real-word conditions (i.e., high outdoor concentrations). Applications should consider cost, noise, safety, energy consumption, pollution generation, ease of use, and environmental lifecycle of materials used. Technologies could be design ...

Innovative, cost-effective mitigation technologies to reduce emissions from small point sources in urban areas. Ideally, technologies would be able to be retrofitted, cost-effective, offer greater mitigation than current technologies, and have low maintenance and energy costs. The mitigation technologies must include efficacy of reducing emissions and improving local air quality and should address ...

Slurry injection into engineered treatment devices, such as supercritical water oxidation technologies, that use higher temperature and pressures than ambient conditions and could provide treatment to complex waste matrices.

Solutions should provide an AI-driven indoor mapping and localization application that utilizes mobile smartphone cameras and sensors to precisely determine a user's position within an indoor setting. This system will emulate human spatial memory by employing AI, video, and directional data to identify and remember routes within an indoor space. Furthermore, it will offer users a streamlined 3D in ...
