“…For example, Lopez and Hestekin (2013; 2015) 48,49 reported energy consumptions of 0.91−8.02 kWh/kg using bipolar membrane electrodialysis, and another report indicated 2.2 kWh/kg using resin-wafer electrodeionization. 50 Aside from performance indicators, comparing Figures S7c and S10g, the time to reach a state of dynamic equilibrium with sodium butyrate was significantly greater than with sodium chloride in this study as well as what is typically observed for sodium chloride desalination. 44,46 To further investigate this, a CDI experiment was conducted in single-pass mode (Figure S1b) using fresh pieces of activated carbon cloth.…”

Separation processes underpin chemical manufacturing, energy and fuel production, resource recovery, and water purification. Capacitive deionization (CDI) is an electrochemical separation technique based on electrosorption of charged species from an aqueous solution. This work reports the development and application of CDI for the extraction and recovery of butyrate, a carboxylate anion that is key to bioenergy production, among other applications. Electrosorption of sodium butyrate was evaluated using a bench-scale CDI system with activated carbon cloth electrodes. Applying an external potential (1.2 V) enhanced the adsorption capacity of activated carbon for butyrate by 250%. Reversible electrosorption was also demonstrated by extracting and recovering butyrate at 1.2 and 0 V, respectively. Performance metrics including butyrate adsorption and desorption capacities, adsorption and desorption rates, charge efficiency, energy consumption, and recovery are reported. This study also investigates the long-term operational stability of the system by cycling the cell more than 1000 times using 1.2 and 0 V for charging and discharging, respectively. Subsequent physicochemical characterization indicates increased oxygen content (from ∼2% to >8%), decreased specific surface area (by ∼20%), and decreased pore volume (by ∼20%), attributed to carbon oxidation. Overall, this work informs the design of CDI for organic anion separation and recovery.

“…To mitigate these inhibitory effects, one approach is in situ product removal (ISPR). Previous studies have successfully applied Resin Wafer (RW) Electrodeionization (EDI) (RW-EDI) to continuously remove CAs from a monoculture butyrate fermentation. , For example, continuous production of 250 g/L pure butyric acid was demonstrated using RW-EDI in a fermentation that employed ISPR . The neutralization chemical (NaOH) was in situ recycled back to the fermentation, which significantly reduced the carbon footprint and the overall production cost.…”

To reduce emissions from combustion of fossil fuels, sustainable aviation fuels (SAFs) have the potential to decarbonize the aviation sector. Redirecting wastes from conventional waste management practices and using them as cost-effective feedstocks for low-carbon fuels can reduce emissions from both waste disposal and fuel combustion. One approach is to upgrade wet wastes to SAF precursors, such as volatile fatty acids (VFAs). In this study, novel membrane-assisted arrested methanogenesis was developed to convert high-strength wastewater to VFAs. Based on experimental results of VFA production, techno-economic and life-cycle analyses were conducted to estimate the potential economic and environmental benefits of SAF production from high-strength wastewater via VFAs. By evaluating three proposed scenarios for VFA production, a minimum production cost of VFA is achieved at $0.60/kg VFA at a wastewater flow rate of 1100 MT/d. For the corresponding VFA-derived SAF, the estimated minimum fuel selling price is $4.64/gasoline gallon equivalent. The life-cycle analysis shows that up to a 71% reduction in greenhouse gas emissions can be achieved relative to its fossil-counterpart along with lower water and fossil-fuel consumption.
