New life for an old process?
Article Abstract:
Biofine Inc., based in Waltham, MA, has completed tests for its process that gears to produce levulinic acid from shredded municipal solid waste. The tests were done at the company's two-ton per density facility. The method that formerly employed dilute sulfuric-acid hydrolysis was replaced by the maleic anhydride process to boost levulinic production. Levulinic acid sees application in vulcanizing rubber, drugs and perfumes. Biofine intends to build a facility for the production of levulenic acid and a 500-ton per density commercial plant in Maryland.

Be up-to-date when choosing process control systems
Article Abstract:
Validation master plan, user requirements, general design specifications, software quality-assurance plan, functional requirements, detail design specifications, factor acceptance test are the essential elements when selecting process control systems. A totally-integrated facility is the user's goal from a control standpoint, which should encompass all process, safety, environmental and auxiliary requirements. The chosen control system should be 'smart,' cost-effective and easy to maintain.

Organize environmental data
Article Abstract:
The market for environmental management information systems (EMISs) is expected to jump from $500 million in 1997 to $1 billion in 2001. The growth has been attributed to the shifting environmental regulations and the ISO 14000 environmental management standard. The number of EMIS packages has increased from 22 in 1995 to 35 in 1998, while the average base price of a system has dropped from $500,000 in 1995 to $100,000 in 1998.
