Scientists from ExxonMobil (Irving, Tex.; www.exxonmobil.com) and the Institute of Chemical Technology (ITQ; Valencia, Spain; http://itq.upv-csic.es) have discovered a new material that could significantly reduce the amount of energy and emissions associated with the production of ethylene. Depending on the…
Photocatalytic reduction of CO2 into a fuel is an attractive way to reduce CO2 emissions into the atmosphere, and there are many projects underway around the world to find ways of converting CO2 into chemicals, such as H2, CH4, ethanol,…
High-surface-area beads filled with microbes are being used to reduce biosolids in wastewater. In one case, Drylet LLC (San Francisco, Calif.; www.drylet.com) has developed engineered porous particles that provide large surface areas (the equivalent of 12 football fields of surface…
A biodiesel fuel blend known as B20 contains oils derived from waste coffee grounds, and will be used to power mass transit buses in London. The fuel is made through a partnership among bio-bean ltd. (London, U.K.; www.bio-bean.com), which has…
Foam dyeing, a new technology for dyeing cotton yarn that is being applied to denim production for the first time, eliminates the use of several chemicals and can reduce water use by up to 90% compared to traditional dyeing. The…
Using zinc-based coatings to protect galvanized steel from corrosion has been standard practice in the steel industry for decades, but these processes have several key disadvantages. First, achieving longer corrosion performance requires thicker layers of zinc, which raises costs and…
