Partnership targets bio-based building blocks from CO2
AkzoNobel N.V. (www.akzonobel.com) has partnered with Dutch start-up company Photanol (both Amsterdam, the Netherlands; www.photanol.com) to manufacture specialty chemicals using a photosynthesis-like process that combines sugar production with fermentation in a single organism. Photanol has developed genetically engineered cyanobacteria that…
A waterless hydraulic-fracturing technique gets field-tested
A method for using liquid CO2, rather than water, as a hydraulic fracturing fluid has been field-tested in a mid-continent oil well, and has benefited well productivity, according to developer Praxair Inc. (Danbury, Conn.; www.praxair.com). Aside from enhanced well performance,…
A new carrier for MBBR technology
Last month, Veolia Water Technologies (Birmingham, England; www.veoliawaterst.co.uk) introduced a new generation of biofilm carriers for moving-bed biofilm reactors (MBBRs). Trade-named AnoxKaldness Z-MBBR, the new carrier is the result of two decades of development work, says the company. Unlike conventional…
Slash energy costs with this new electrowinning anode
The research group of Masatsugu Morimitsu at Doshisha University (Kyoto, Japan; www.doshisha.ac.jp) has developed an “evolutionary” electrowinning process for the production of rare and base metals that promises to reduce both the power consumption and environmental burden. The process features…
November Chementator Briefs
Graphene continues to show new, promising properties Researchers from Monash University (Melbourne, Australia; www.monash.edu.au) have discovered that graphene oxide sheets can change their structure and become liquid droplets spontaneously. Because graphene droplets change their structure in response to an…
‘Clean power’ demo
Last month, NET Power, LLC (Durham, N.C.; www.net-power.com) announced the completion of major project agreements for its first-of-a-kind power plant — a 50-MWth demonstration plant that will validate the world’s first natural-gas power generation system that produces no air emissions,…
Large-scale CCS
Last month, the first commercial-scale, post-combustion carbon capture and storage (CCS) plant started up in Saskatchewan, Canada. The SaskPower facility at the Boundary Dam Power Station is expected to capture around 1 million m.t./yr of CO2, which is up to…
Making nanoparticles
Scientists from the Materials Science and Technology Div. of the U.S. Naval Research Laboratory (Washington, D.C.; www.nrl.navy.mil) have developed a one-step process to form oxide nanoparticles. The technique is capable of producing large quantities (10 g) of oxide nanoparticles —…
Combine wastewater treatment with biofuel production
Algae Systems LLC (Daphne, Ala.; www.algaesystems.com) has inaugurated a demonstration plant that integrates municipal wastewater treatment with the cultivation of biofuel-producing algae. Pretreated and disinfected municipal wastewater is passed to Algae Systems offshore floating-bag photobioreactors (PBRs), which are located in…
October Chementator Briefs
A step closer to bio-based acrylic acid Last month, BASF SE (Ludwigshafen, Germany; www.basf.com), Cargill (Minneapolis, Minn.; www.cargill.com) and Novozymes (Copenhagen, Denmark; www.novozymes.com) achieved another milestone in the joint development of technologies to produce acrylic acid from renewable resources.…
