Waste tires have been used mainly for recovering energy sources; only small proportions of the carbon black contained in these tires are recycled, since mineral ash accounts for around 20% of its content. Around three kilograms of carbon black—also known as industrial soot—are found in a standard car tire.
A team led by researchers from the University of Alberta (Canada) Scientists has developed a hybrid sodium-ion capacitor (NIC) using active materials in both the anode and the cathode derived entirely from peanut shells—a green and highly economical waste globally generated at more than 6 million tons per year. Scanned from 1.5–4.2
The partnership will begin with a project in the battery anode space with the development of a novel process for the production of hard carbon from bio-waste. Using readily available, sustainable bio-waste material will provide Sparc with a strong environmental value proposition when compared with conventional sources of hard carbon.
Using a novel, reusable carbon material derived from old rubber tires, an Oak Ridge National Laboratory (ORNL)-led research team has developed a simple method to convert used cooking oil into biofuel. The patent-pending, waste oil-to-biofuel conversion adds a new approach to waste tire recycling initiatives. —Hood et al.
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.
By some estimates, as much as 15,000 metric tons per year of lithium carbonate could be recovered from a single geothermal power plant in the Salton Sea area of California—one of the most mineral-rich brine sources in the United States. Concentrated brines left over from the operation are then pumped back into the ground.
The dominant conventional process for refining battery-grade lithium from hard rocks such as spodumene and lepidolite relies on sulfuric acid and produces sodium sulfate as a byproduct—a waste stream that requires costly and proper disposal. Tesla will use inert reagents such as soda ash and lime.
In addition, similar to other amine-based sorbents, this hybrid sorbent is regenerable with waste heat or thermal energy at The desorbed CO 2 is simultaneously sequestered as innocuous baking soda (sodium bicarbonate, NaHCO 3 ). Concept of CO 2 sorption by polyamine-Cu(II) complex.

In the next recycling step after the glass recyclate has been processed and all possible waste materials have been removed, Saint-Gobain Glass turns it into plate glass in Herzogenrath, Germany. Saint-Gobain Glass then mixes the recyclate with, among other things, quartz sand, sodiumcarbonate, and chalk—the basic components of glass.
The study, published by the Mineta National Transit Research Consortium (MNTRC), observed a reduction in amount of particulate matter, number of elements, and elemental carbon; the reduction is considered beneficial to promoting the clean air and human health. Kumar et al. Ultra-low-sulfur diesel (ULSD) was used as base fuel.
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.
Projects selected for the Electric Vehicles for American Low-Carbon Living (EVs4ALL) program ( earlier post ) aim to expand domestic EV adoption by developing batteries that last longer, charge faster, perform efficiently in freezing temperatures and have better overall range retention. Award amount: $3,198,085). Award amount: $2,945,000).
The approach, described in a paper in the journal Nature Communications , could be an important advance in carbon capture and sequestration (CCS). They have significant performance advantages over the carbon-absorbing materials used in current CCS technology. carbon dioxide uptake and release over repeated cycles.
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. Silica is essential for the high performance of our tires.
The solicitation was designed as a call for early-stage clean energy innovations that fall within five defined technology areas: energy efficiency; energy storage; AI/machine learning; advanced power electronics/power conditioning; and zero- and negative-carbon emission generation.
The new thermochemical cycle devised by the team has four main steps: Thermal treatment of a physical mixture of Na 2 CO 3 (sodiumcarbonate) and Mn 3 O 4 (manganese (II, III) oxide) to produce MnO (manganese (II) oxide), CO, and ?-NaMnO NaMnO 2 at 850 °C; Na + extraction from ? NaMnO 2 at 850 °C; Na + extraction from ?-NaMnO
New Zealand-based waste gas and syngas to fuels company LanzaTech ( earlier post ) has attracted US$18 million in Series B financing from investors led by China-focused venture capital firm Qiming Ventures. LanzaTech uses proprietary bacteria to convert industrial waste gases into fuels and chemicals. Gary Reischel. Köpke et al.
Nuclear energy is one of the key low-carbon energy technologies that can contribute, alongside energy efficiency, renewable energies and carbon capture and storage, to the decarbonization of electricity supply by 2050. Progress in implementing plans for the disposal of high-level radioactive waste will also be essential.
Carbon Capture (5 projects). 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. CARBON CAPTURE. Water (1 project).
Niquelandia provided the SMP Refinery with nickel carbonate. The scenarios are designed based on filtration and management of waste limitations based on SMP Refinery’s existing production capacity and flowsheet of 25,000mtpa and 2,000mtpa of refined nickel and cobalt cathode respectively. SMP Refinery restart scenarios.
By using renewable electricity, the initial unit will enable a carbon saving of up to 350,000 tons of CO 2 per year, equivalent to the emissions of more than 40,000 households. Nouryon already has 1000 MW of electrolysis capacity installed in various facilities, using three processes: chlor-alkali, sodium chlorate, and water electrolysis.
For example, if you put a pair of carbon atoms at each point (forming two FCC sub-lattices), you get diamond. If you put a pair of sodium and chlorine atoms at each lattice point, they form sodium and chlorine sub-lattices and you get salt. Materials Thermoelectrics Waste Heat Recovery' CIS is a bit more complicated.
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 companys plan is to electrochemically strip carbon dioxide out of the ocean, store or use the CO 2 , and then return the water to the sea, where it will naturally absorb more CO 2 from the air. Captura is one of a cadre of startups eyeing Earths oceans as a carbon sink ready to be harnessed.
In an integrated system, stored hydrogen can be converted back to electricity or used as a feedstock with atmospheric or source carbon dioxide (CO 2 ) to produce a liquid fuel for heavy-duty vehicles including trucks and jet planes. Analysis of excess and/or waste hydrogen sources. transit buses or other heavy duty vehicles).
Pyrometallurgy, which traditionally doesn’t recover carbon or lithium, seems likely to be phased out. 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. They need to contain them.
At full scale, Aqua will provide 30% of the nickel and lithium carbonate needed at 6K’s PlusCAM facility. The companies’ patented processes also eliminate the production of thousands of tons of sodium sulfate waste—a byproduct of traditional cathode production and recycling methods.
What is the impact on the EV lifecycle carbon footprint? A 30% decrease in grid carbon intensity would reduce emissions from the battery production chain by about 17%. Audi’s e-Tron batteries are manufactured at a carbon-neutral facility. So, how clean is EV battery manufacturing? Is it becoming cleaner?
