Making bioethanol directly from starch

Today, the cost of enzymes continues to make bioethanol uncompetitive as a fuel. Eliminating the need for amylases, which are used to hydrolyze starch into fermentable sugars, would be a key step toward reducing the operating costs for producing bioethanol.…

Air-capture of CO2 using waste process heat

Carbon-negative technology being commercialized by Global Thermostat LLC (New York, N.Y.; www.globalthermostat.com) removes carbon dioxide directly from the atmosphere using low-cost waste process heat from industrial processes. The technology works in a similar fashion to cogeneration approaches and could transform…

A desalination membrane that is resistant to chlorine

The major drawback of existing membranes for desalination plants is that the membranes are not tolerant of oxidizing agents, such as chlorine. To overcome this drawback, a team of researchers from the University of Melbourne (www.unimelb.edu.au) and CSIRO (Melbourne, Australia;…

New cryogenic technology for cooling superconducting cables

Industrial gases specialist Messer Group GmbH (Bad Soden, Germany; www.messergroup.com) has developed a new cryogenic technology that makes it possible to use liquid nitrogen (LN2) to cool high-temperature superconducting (HTS) cables down to –209°C, which is significantly lower than that…

An effective graphene-based desalination membrane

Researchers from Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov) have demonstrated an efficient desalination process using a porous graphene-based desalination membrane. While the thinness of the freestanding graphene (roughly 0.3 nm) allows for significantly higher flux than traditional…

April Chementator Briefs

Nanocellulose pilot Sappi Ltd. (Johannesburg; South Africa; www.sappi.com) will build a pilot-scale plant for low-cost nanocellulose (Cellulose NanoFibrils; CNF) production at the Brightlands Chemelot Campus (Sittard-Geleen, the Netherlands; www.brightlands.com). The pilot plant will test the manufacturing of dry re-dispersible CNF…

Lignin to adipic acid

A new study from the National Renewable Energy Laboratory (NREL; Golden, Colo.; www.nrel.gov) demonstrates the conversion of lignin-derived compounds to adipic acid, an important precursor for making nylon and other chemicals. The new route offers a “greener” alternative to conventional…

Biomass pretreatment approach can reduce enzyme requirements

Biomass is a recalcitrant, heterogeneous matrix of cellulose, hemicellulose and lignin that resists microbial and enzymatic breakdown. Overcoming this recalcitrance is the major economic barrier to the conversion of biomass to sugars or other chemicals. Heat, acid and other chemicals…
