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…
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…
An international group of researchers, coordinated by the Institute of Solar Research of the German Aerospace Center e.V. (DLR; Cologne, Germany; www.dlr.de), is developing a sulfur-based storage system for solar power. Large-scale chemical storage of solar power and its overnight…
Efficient distillation Last month, Toyo Engineering Corp. (Toyo; Chiba, www.toyo-eng.co.jp) and Koch-Glitsch, LP (Wichita, Kan.; www.koch-glitsch.com) announced a new partnership to distribute Toyo’s energy-saving distillation system, SuperHIDiC, to new global markets in Europe and the Middle East. SuperHIDiC provides energy…
The New Energy and Industrial Technology Development Organization (NEDO, Kawasaki City; Japan; www.nedo.go.jp), in partnership with Japan Technological Research Assn. of Artificial Photosynthetic Chemical Process (ARPChem) members, Mitsubishi Chemical Corp. and the Tokyo Institute of Technology, has developed a hyperstable…
Researchers from the Ulsan National Institute of Science and Technology (Ulsan; www.unist.ac.kr) have found a new way to increase the energy efficiency of metal-air batteries — which are next-generation energy devices — by adding the conducting polymer polypyrrole (pPy). According…
Recovery of the essential plant nutrient phosphorus from wastewater can be an effective way to reduce runoff into waterways while avoiding the need to obtain the element from mined minerals. While phosphorus recovery from wastewater effluent performs well, it is…
Nippon Paper Industries Co. (NPI; Tokyo, Japan; www.nipponpapergroup.com) has installed the world’s largest facility of its kind for the commercial production of cellulose nanofiber (CNF). Located at its Ishinomaki Works in Miyagi Prefecture, the $16-million investment has a production capacity…
