Green design

Room-temperature ionic liquids have received much attention as green designer solvents. We first demonstrated that ionic liquids acted as good medium for lipase-catalyzed production of polyesters. The polycondensation of diethyl adipate and 1,4-butanediol using lipase CA as catalyst efficiently proceeded in l-butyl-3-methylimidazolinium tetrafluoroborate or hexafluorophosphate under reduced pressure. The polymerization of diethyl sebacate and 1,4-butanediol in l-butyl-3-methylimidazolinium hexafluorophosphate took place even at room temperature in the presence of lipase BC. ... 

Fueled by natural gas, the 200-kW fuel cell will be a continuous source of power. The residual heat of almost 700,000 Btu per hour will be used for the shop s domestic hot water system. In case of a power disruption, the fuel cell will automatically supply electricity to the building s non-emergency lights. Combined with other sustainable green design elements, NYC Transit expects to use 36% less energy over the life of the new facility. 

Beckman emphasized that the convergence of chemistry and engineering is needed to accomplish real green design. Beckman cited an article from the Journal of Business ResearcE on how to achieve sustainable product design. The article features three approaches ...
