A new company — Tsubame BHB Co., Ltd. (Tokyo, Japan; www.tsubame-bhb.co.jp) — has been established to commercialize the world’s first on-site production of ammonia for supplying amino-acid synthesis, fermentation materials and fertilizers. The company — a joint venture of Ajinomoto…
Researchers at Princeton University (Princeton, N.J.; www.princeton.edu) have developed a water treatment technique that injects carbon dioxide gas into a stream of water to separate suspended particles that would be difficult to remove by sedimentation or by microbes. The system,…
Additive manufacturing (3-D printing) has quickly gained popularity, due in part to its potential for rapidly creating customized parts. However, one inherent limitation of additive manufacturing — specifically the high-speed fused deposition modeling (FDM) technique — is the potential for…
Although there are several ways to reduce the phenol concentration in industrial effluent, they each have drawbacks. Chemical treatment, such as adsorption and stripping, is fast but expensive, and the chemical degradation of phenol leads to the formation of toxic…
A new electrochemical water-treatment process developed in the laboratory of T. Alan Hatton, professor of chemical engineering at Massachusetts Institute of Technology (MIT; Cambridge; web.mit.edu), employs functionalized electrodes to selectively remove contaminants, such as pesticides and pharmaceuticals, at extremely low…
On May 31, Climeworks (Hinwill/Zurich, Switzerland; www.climeworks.com) inaugurated its — and the world’s — first commercial plant that captures CO2 directly from air. The Direct Air Capture (DAC) facility, located at the waste-utilization plant of KEZO in Hinwill, Switzerland, will…
A spray-drying technology that applies an electrical charge to feedstock as it exits the atomizing nozzle allows significant reductions in processing temperature and can eliminate downstream processing steps. The charge application can improve control over particle morphology, lengthen shelflife of…
Recycling sachets Later this year, Unilever (London, U.K.; www.unilever.com) plans to open a pilot plant in Indonesia to test the long-term viability of its new technology for recycling plastic sachet (small bags) waste. The process, called CreaSolv, has been developed…
Membrane distillation (MD) — a thermal desalination technique used for recovering pure water from concentrated salt solutions — is hampered by high energy consumption, low single-pass recovery rates and by the need to use expensive heat exchangers to handle the…
