Technical innovations in light emitting diodes (LEDs) and photovoltaics have consistently reflected the similarities between the two technologies. In fact, research groups at many universities, such as  the University of Michigan (Ann Arbor, Mich.; www.umich.edu) and the University of Southern California (USC; Los Angeles, Calif.; www.usc.edu), are studying both simultaneously. With pressing consumer...

In a ceremonious sense, the marking of a new year thankfully lets us put certain things to rest and look ahead to a fresh start. At the same time, a majority of the previous year’s challenges are still at hand — if not intensified. The latter is certainly true for the chemical process industries (CPI) in a broad sense and is especially the case this year in the context of greenhouse gas (GHG)...

Chemical products and processes make modern life possible. The systems that provide housing, transportation, health care, and food for billions of people rely on chemical products, but as demand for these essential materials grows, the environmental impacts of the products and the processes that create them are becoming a greater concern. As this concern about the magnitude of the associated environmental...

What we can do to support its goals Green engineering, as explained by chemists and bio-scientists, includes production of energy and materials from "green" feedstocks, such as biomass and microorganisms, with the intent of reducing energy, waste, greenhouse gases (GHGs) and water consumption. By extension, other contributions that reduce GHG emissions also support green engineering. The obvious...

The amount of crude oil remaining in depleted oil fields has been estimated to be about 50 – 80% of the total estimated oil reserves. In the past, CO2 has been injected into such wells for enhanced-oil recovery — a technique that displaces the oil and stores the greenhouse gas. Now, a completely different approach to monetizing the carbon is being considered by Inpex Holdings Inc. (Tokyo...

In Malaysia, the raw material for biodiesel production has been palm oil. However, making biodiesel can conflict with the oil’s use as food, and growing palm oil (even for food) has caused the destruction of tropical forests in Borneo, Sumatra and other regions. A team from the Dept. of Chem. Eng. at the Universiti Teknologi Petronas, (Perak, Malaysia...

China will likely achieve and may even exceed its target to obtain 15% of its energy from renewables by 2020, according to a new report released by the Worldwatch Institute (www.worldwatch.org). If China's commitment to diversifying its energy supply and becoming a global leader in renewables manufacturing persists, renewable energy could provide over 30% of the nation's energy by 2050. That is the major...

Technology to copolymerize carbon dioxide and propylene oxide (PO) was first discovered in 1960s, but has not been commercialized due to the formation of cyclic propylene carbonate (CPC) by a “back-biting” reaction, which leads to the formation of unstable, low-molecular-weight copolymers. This limitation has essentially been eliminated, thanks to a new catalyst developed by Professor Kyoko...

Within five years, four large power plants in Europe will be outfitted — for testing at the pilot scale — with energy-efficient CO2-filtering membranes that are being developed at the Norwegian University of Science and Technology (NTNU; Trondheim; edlinks.che.com/6901-531). Professor May-Britt Hägg, head of the membrane research group (MEMFO) at NTNU’s chemical engineering...

A plasma-based waste-treatment process will be installed in Dow Corning Corp.’s silicon-products-manufacturing plant in Midland, Mich., where it will recycle chemical wastes, help lower the site’s consumption of natural gas by 400-billion Btu/yr and help reduce the plant’s total emissions by 75%. The installation will mark the first use of the technology in a chemical process plant, says...
