ICL researchers develop new membrane-based system for cheap, efficiently made biofuels

Green Car Congress

The membrane successfully protects the micro-organisms from the extractant, which, although ideal in other respects, is a metabolic inhibitor. Biofuels can be produced by fermenting waste biomass and recovering the fuel from the fermented solution using an extractant. MJ kg -1 , substantially less than other recovery processes (17.0–29.4

Efficient recovery of lithium from spent LiFePO4 batteries via air oxidation–water leaching at room temperature

Green Car Congress

The toxic electrolytes, binder, and other organic chemicals will result in serious environmental pollution if the spent batteries are not properly treated. As the most cheap and green oxidant, air may be suitable as the oxidant to selectively extract lithium from the LFP cathode material in the water leaching process.

China researchers synthesize high-density aviation fuel with cellulose

Green Car Congress

Scientists in China have developed a process for converting cellulose from plant waste from agriculture and timber harvesting into high-density aviation fuel: a polycycloalkane mixture. Tuning the reaction conditions also permits the selective production of methyl cyclopentane, which can be used as high-octane-number gasoline additive.

Lund researchers develop optimized two-phase enzymatic process for production of biodiesel

Green Car Congress

An alternative approach is the use of immobilized lipase-catalyzed transesterification in the presence of an organic solvent. This part is oriented towards the organic layer, such that the lipid can easily enter the active site and the hydrophilic products can diffuse into the aqueous layer. —Mangas-Sánchez and Adlercreutz.

Non-bike bike gear tested: Foldylock Forever is the most secure folding lock, period.

Baua Electric

Someone will eventually mention Lockpicking Lawyer and say you’re all wasting your time. It’s not cheap – I’ll tell you that immediately. But good quality isn’t cheap, and if I could go back and spend that $125 before my $3,000 e-bike was stolen last year , I’d do it in a heartbeat. Basically, there’s little consensus.

QUB spin-out to commercialize to technique for production of MOFs; storage for natural gas vehicles

Green Car Congress

Chemists at Queen’s University Belfast (Ireland) have devised a novel environmentally friendly technique which allows the rapid production of metal-organic frameworks (MOFs). MOFs are crystalline, sponge-like materials composed of two components: metal ions and organic molecules (linkers). Pichon et al. Click to enlarge. —Prof.

Delivery of renewable isooctane to Audi tips interesting potential non-biomass pathway for biogasoline; “e-benzin” as solar fuel

Green Car Congress

Global Bioenergies, founded in 2008, has developed a synthetic isobutene pathway that, when implanted in a micro-organism, enables the organism to convert sugars (e.g., The addition of Global Bioenergies’ synthetic isobutene pathways into the LanzaTech organisms would presumably offer another end product for the LanzaTech process.
