Researchers use cellulose nanofibrils in 3D-printed concrete

A research team at the University of Virginia School of Engineering and Applied Science (Charlottesville, Va.; engineering.virginia.edu) is the first to explore how an emerging plant-based material, cellulose nanofibrils, could amplify the benefits of 3D-printed concrete technology. “The improvements we…

Chementator Briefs

Tanning Agent Södra Skogsägarna (Södra; Växjö, Sweden; www.sodra.com) is investing in a production line at Värö that will create a tanning agent from tree bark. This new tannin can be used to process leather in a more environmentally friendly way,…

Versatile production of biopolymers in new semi-crystalline format

Bio-based polymers, such as polyhydroxyalkanoate (PHA), are seeing increasing application as a more sustainable alternative to fossil-based materials. A new, flexible production platform developed by CJ Biomaterials, Inc. (Woburn, Mass.; www.cjbiomaterials.com) is now enabling the production of PHA in both…

A proof-of-concept “BionicHydrogenBattery”

At a press conference during Achema 2024, Festo SE & Co. KG (Esslingen, Germany; www.festo.com) presented the BionicHydrogenBattery — a new concept for the simple storage and safe transportation of hydrogen. Currently, H2 can only be stored and transported safely…

Biomimetic membrane may have promising applications

Researchers from the Adolphe Merkle Institute (AMI; Fribourg, Switzerland; www.ami.swiss), together with international collaborators, have pioneered a novel method for creating thin, energy-converting membranes that mimic the structure and function of biological cell membranes. This discovery, described in a recent…

Electrocatalytic reduction of CO2 into a range of chemicals

At Achema in June, GIG Karasek GmbH (Gloggnitz, Austria; www.gigkarasek.com) introduced the ECO2Cell, an electrochemical CO2-recycling technology that utilizes proprietary catalysts to convert captured carbon dioxide into a range of chemicals. Using only water, CO2 and electricity as process inputs,…

New bio-based concrete admixture is scaling up production

A new biomass-based liquid admixture for concrete uniquely combines the benefits of traditional performance-enhancing additives with decarbonization. Hydrous bio-graphene oxide (hBGO), developed by AlterBiota (Edwardsville, Nova Scotia, Canada; www.alterbiota.com), is a stable, high-solids dispersion that helps to improve strength and…

A biocatalytic process for producing nitriles — without cyanide

Nitrile compounds (R–N≡N) are important for the manufacturing of fragrances, pharmaceuticals, superglue and chemical-resistant gloves. Currently, such nitrile compounds require the use of highly toxic cyanide in their synthesis. Now, an alternative cyanide-free chemo-enzymatic cascade process is being developed by…

Pilot plant produces climate-friendly cement clinker

Concrete production is responsible for 6–9% of global anthropogenic CO2 emissions. “The largest contribution to that comes from the production of cement, a precursor product,” says Peter Stemmermann from the Institute for Technical Chemistry (ITC) at the Karlsruhe Institute of…

New structured packing introduced at Achema

At Achema 2024 (Frankfurt, Germany; June 10–15), Sulzer Chemtech (Winterthur, Switzerland; www.sulzer.com) revealed MellapakEvo (photo), the latest addition to its structured-packing product family. The MellapakEvo structured packing has been developed to enhance the efficiency and capacity of distillation columns, maximizing…
