Biogas from brewery wastewater makes power with a fuel cell

This month, a demonstration project to generate power from fuel cells running on biogas has begun at Asahi Breweries’ Ibaraki Brewery. Coordinated by Asahi Quality & Innovations, Ltd., an independent research subsidiary of Asahi Group Holdings, Ltd. (Tokyo, Japan; www.asahigroup-holdings.com),…

Fruit peels help recover metals from e-waste

Scientists from Nanyang Technological University (NTU; Singapore; www.ntu.edu.sg), led by professor Madhavi Srinivasan, have developed a method of using orange peel waste to extract precious metals from spent lithium-ion batteries and to make batteries from those recovered metals, creating minimal…

Graphene-POSS polymer additives enable lightweighting

MITO Material Solutions (Indianapolis, Ind.; www.mitomaterials.com) has developed a proprietary graphene-functionalization technique that produces unique strength-enhancing additives for a wide variety of polymers and composites. The additives significantly improve mechanical properties (including tensile strength, flexural modulus and others) of the…

Single-atom thin platinum makes a sensitive chemical sensor

Boosting the sensitivity of solid-state gas sensors is often achieved by incorporating nanostructured materials as the sensing element. However, interfacial effects at nanoparticles, grains or contacts can lead to non-linear responses, high electrical resistance or electrical noise. A possible way…

An electrochemical process treats wastewater from biofuels production

Researchers from the School of Chemical and Biomolecular Engineering at the Universiy of Sydney (Sydney, Australia; www.sydney.edu.au), led by Alejandro Montoya, have developed an electrochemical oxidation process to clear up wastewater, which is heavily contaminated with organic and inorganic species…

A more efficient way to upgrade lignin bio-oils

Lignin bio-oil is a common waste stream formed during the production of cellulose and ethanol from biomass. Due to its high oxygen and low hydrogen content, lignin bio-oil must be upgraded via hydrogenation and deoxygenation before it can be used…

New process efficiently filters hormones from water

Drinking water can be contaminated with micropollutants, including steroid hormones that are used as medical substances and contraceptives. Although their concentration in wastewater may be only a few nanograms per liter, this small amount can already damage human health and…
