Two-pronged approach recycles textile waste while also producing glucose
Glucose is a key pillar in producing bio-based alternatives to conventional chemicals, but finding industrially viable, non-food-competitive sources for glucose has proven challenging, due to the difficulty in obtaining glucose from hemicellulosic materials, such as woody biomass, in a cost…
Short-loop battery recycling uses vegetable-oil nanoemulsion
Efficient and sustainable recycling of lithium-ion batteries is a crucial element in electrifying transportation. Black mass is a mixture of cathode and anode materials remaining after disassembly and shredding of end-of-life lithium-ion batteries (LIBs). Many valuable materials, including lithium and…
An integrated process makes valuable mid-chain carboxylic acids from organic waste
A dual process strategy bridging fermentation and electrochemistry is enabling the production of mid-chain carboxylic acids (MCCAs) — important and valuable precursors to a number of products — using inexpensive organic waste streams from breweries, distilleries and dairies. Developed by…
Selective silica removal makes for better bauxite beneficiation
The extraction of alumina from bauxite is significantly impacted by the silica content of the ore — specifically the presence of silica in kaolinite (Al2Si2O5(OH)4). This is because traditional bauxite-beneficiation methods, such as washing, flotation and particle-size separation, also typically…
