A continuous biotreatment process that degrades phenol in wastewater
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…

Plant Watch Ineos announces plans to build new PDH plant, increase ethylene capacity June 12, 2017 — Ineos (Rolle, Switzerland; www.ineos.com) announced plans to construct a propane dehydrogenation (PDH) unit in Europe. The plant will produce 750,000 metric tons per…
Finely tuned electrodes for water treatment
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…
Commercial debut for a process that captures CO2 directly from air
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…
Electrostatic spray drying protects heat-sensitive products
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…
CNT membrane aids distillation of brine
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…
Harvesting agricultural fertilizers from wastewater sludge
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…
Scaleup for cellulose nanofiber production
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…
Low-cost solar collectors provide renewable process heat
The first pre-commercial demonstration has started for a system that can provide steam for industrial process heat using solar energy at prices lower than using natural gas. The technology uses solar thermal collectors to generate hot water, air or steam…
