A new source of carbon: food-processing wastes
Article Abstract:
Shimazu Corp. and Research Institute of Innovative Technology for the Earth (RITE), both from Tokyo, Japan, have developed a method of producing carbon from food-processing wastes. The process starts with the fermentation of food wastes to form methane gas through the use of anaerobic microbes. Afterwards, methane is placed in a fluidized-bed reactor (FBR) heated at 500-600 deg Celsius, and with the aid of a nickel-based catalyst, methane will be further broken down into carbon and hydrogen. The carbon produced will be separated from the FBR and will be recycled.

Reverse logic: methane from hydrogen
Article Abstract:
A new method is allowing production of methane from hydrogen through seawater electrolysis with the use of solar energy for electricity generation. The process, designed by researcher Kouji Hashimoto in Tohoku University Institute for Materials Research in Sendai, Japan, is developed to be employed for a liquefied-natural-gas-operated seaside thermoelectric power facility. The process has undergone testing in a three-cube-meter over density methane reactor and is estimated to produce roughly $85/mt in a 4,200-cube-meter over density facility.

A more-efficient way to make L-aspartic acid
Article Abstract:
Nippon Shokubai Co. of Osaka, Japan, has employed genetic engineering to develop an enzyme that makes L-aspartic acid that is 20 to 30 times quicker than the common enzyme. A bacillus makes the aspartese enzyme after it has been altered to produce the enzyme in a concentration 50 to 60 times bigger than that of conventional aspartese. The enzyme's lifetime has also been increased ten times from that of the conventional enzyme by immobilizing the bacilli in a fixed catalyst bed, instead of gel carriers.
