The study, done with collaborators Wake Forest University and Georgia Institute of Technology and detailed in Chemistry Select , provides a pathway for inexpensive, environmentally benign and high value-added waste tire-derived products—a step toward large-scale biofuel production, according to ORNL co-author Parans Paranthaman.

The platform technology is also being commercialized for conversion of waste brines to chemicals and desalinated water. Mangrove’s modular solution can be scaled to any capacity and co-located with upstream lithium producers or cathode and cell manufacturers. The process creates an effluent stream with salinity below 3,000 ppm.

The resulting blend exhibits properties similar to conventional biodiesel, while reducing waste and improving conversion. Biodiesel is produced from vegetable oils or animal fats via a transesterification reaction with a short chain alcohol and a basic catalyst such as sodium or potassium methoxide.

for the materials and possibly good enough for consideration for waste heat recovery in automotive exhaust systems. The high thermoelectric figure of merit is expected to enable the conversion of 14% of heat waste to electricity. at 700 °C (973 K), in half-Heusler alloys—about 60% higher than the best reported ZT of 0.5

Using electrolyzed water rather than harsh chemicals could be a more effective and environmentally friendly method in the pretreatment of ethanol waste products to produce an acetone-butanol-ethanol fuel mix, according to research conducted at the University of Illinois. Using the strong sulfuric acid method, there was no fuel produced.

Several companies are developing chemical processes, but these are still at pilot scale, and Aqua’s execs see serious challenges in delivering the required product purity and dealing with waste streams. There are real challenges with waste streams—they yield a lot of sulfuric acid and sodium sulfate, which will need to get landfilled.

The first thing postdoctoral scholar and lead author Bingjun Xu and graduate student Yashodhan Bhawe did was to perform a thermodynamic analysis demonstrating that it is unlikely, if not impossible, to split water with a two-step cycle where there is complete conversion between the oxidized and reduced forms at below 1,000 °C. van Amerongen.
