A new study on the combustion properties of biodiesel for use in urban transit buses found that using biodiesel can effectively reduce the mass of particulate matter released in both hot and cold idle modes. Depending on the feedstocks and blending ratios used to produce the fuel, variations in chemical properties may also be an issue.
Brazilian researchers have demonstrated a new chemical approach for producing biodiesel from domestic cooking oil waste by using lithium hydroxide mixed with either sodium hydroxides or potassium hydroxides as catalysts. Before, in practice, these were just restricted to sodium hydroxide and potassium hydroxide.
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. —Calero et al. Calero et al.
A new study published in the journal Nature Materials has found a way to suppress the thermal conductivity in sodium cobaltate so that it can be used to harvest waste energy, with potential applications such as automotive waste heat recovery. CoO 2 , which has a large-period superstructure. —Voneshen et al.
The LDH sorbent is made up of layers of the materials, separated by water molecules and hydroxide ions that create space, allowing lithium chloride to enter more readily than other ions such as sodium and potassium. The technique is very sensitive to hydrogen atoms, making it ideal for studying water.
The projects, led by universities, private companies, and national laboratories, were selected to develop technologies to advance UNF recycling, reduce the volume of high-level waste requiring permanent disposal, and provide safe domestic advanced reactor fuel stocks. Award amount: $1,580,774). Award amount: $2,711,342).
a global engineering consultancy firm, has delivered its report that evaluates NOVONIX’s all-dry, zero-waste cathode synthesis process. The Hatch study found that NOVONIX’s process may potentially reduce power consumption by an estimated 25% and practically eliminate waste byproduct generation over the conventional process.
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.
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.
This process eliminates the acid-leaching of spodumene and the production sodium sulfate waste, which will make Tennessee Lithium one of the world’s most sustainable lithium hydroxide operations, according to the company. Based on prior studies, Piedmont plans to invest approximately $600 million in the development of the operation.
Nouryon (formerly AkzoNobel Specialty Chemicals), Tata Steel and the Port of Amsterdam have joined together to study the feasibility of a large green hydrogen cluster in the Amsterdam region. The three parties consider green hydrogen as vital for reaching climate targets and building a more circular economy—e.g.,
One of these processes, the sulfur-iodine cycle, has been studied extensively, and even piloted for implementation. NaMnO 2 (sodium manganate) at 850 °C; oxidation of MnO in the presence of Na 2 CO 3 by water to produce H 2 , CO 2 , and ?-NaMnO NaMnO 2 at 850 °C; Na + extraction from ? NaMnO 2 at 850 °C; Na + extraction from ?-NaMnO
for the materials and possibly good enough for consideration for waste heat recovery in automotive exhaust systems. The study by Yan et al. The high thermoelectric figure of merit is expected to enable the conversion of 14% of heat waste to electricity. The study by Biswas et al. was published in Nature Chemistry.
Olivine is a CO 2 -reactive waste product that can be returned as tailings after capture carbon from the air. Travertine will launch a transformative process that integrates strong acid treatment of mining waste or tailings with electrolytic acid recycling. Pacific Northwest National Laboratory. University of Nevada, Reno.
Solvay is investing at its Livorno, Italy site to launch the company’s first unit of circular highly dispersible silica (HDS) made with bio-based sodium silicate derived from rice husk ash (RHA). Rice husk is an abundantly available agricultural waste.
Jervois will initially lease SMP Refinery from CBA, providing Jervois access to undertake a Feasibility Study (FS) for a restart. During its due diligence, with regard to ICO concentrate, Jervois assessed implications at SMP Refinery both for processing (including impurity removal and physical handling constraints) and also waste generation.
Pre-feasibility studies have shown that the Jadar project has the potential to produce both battery-grade lithium carbonate and boric acid. The project under study consists of an underground mine, sustainable industrial processing and waste facilities as well as associated infrastructure. Economic assumptions.
Writing in the journal Nature Communications , the researchers reported finding this unusual arrangement of atoms while studying nanoparticles made from the semiconductor copper-indium sulfide (CIS), which is being actively studied for use in solar cells.

Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components. García-Cubero et al.
Lithium-intercalation compounds and sodium-intercalation compounds are used for anode and cathode, respectively. Sodium-ion based rechargeable batteries (SIBs, e.g., earlier post ) are of interest due to sodium’s abundance, far lower prices, and a greener synthesis while maintaining a similarity in ion-insertion chemistry.
The current predominant method for the transesterification of triglycerides (plant and animal oils and fats) to biodiesel (a mixture of esters) uses chemical catalysts (sodium or potassium hydroxides or alkoxides). In their study, the Lund researchers used a liquid formulation of T. —Mangas-Sánchez and Adlercreutz.
Wastewater treatment plants (WWTPs), waste streams from food and beverage processing plants, crop farms and animal feed facilities, and municipal landfills are all biogas sources. Analysis of excess and/or waste hydrogen sources. Combined heat and power (CHP) fuel cell systems.
A recent study from the Pacific Northwest National Laboratory (PNNL) looks at molten-salt batteries that can “freeze” their charge for months until required. We have some test cases ongoing for six months at this time,” says Minyuan “Miller” Li , first author of the study. When it comes to potential applications, adds Vincent L.
Waste Heat Capture (2 projects). Eagle Picher, in partnership with the Pacific Northwest National Laboratory, will develop a new generation of high energy, low cost planar liquid sodium beta batteries for grid scale electrical power storage applications. (DOE WASTE HEAT CAPTURE. Building Efficiency (3 projects). ENERGY STORAGE.
This chemically rearranges seawater molecules (hydrogen, oxygen, and sodium chloride) based on their constituent ions charge, resulting in the production of an acid (hydrochloric acid) and a base (sodium hydroxide). The acid stream, however, becomes a waste by-product that will need to be neutralized.
A focus on tailpipe CO2 emissions has distracted away from the impact of car production, suggests Professor Frank Figge who co-authored the ‘Sustainable Value in Automobile Manufacturing’ study. Its sodium oxide value contributions show the worst level of resource efficiency in the entire study.
