Diffusion of oxygen in cork.
2012
International audience; This work reports measurements of effective oxygen diffusion coefficient in raw cork. Kinetics of oxygen transfer through cork is studied at 298 K thanks to a homemade manometric device composed of two gas compartments separated by a cork wafer sample. The first compartment contains oxygen, whereas the second one is kept under dynamic vacuum. The pressure decrease in the first compartment is recorded as a function of time. The effective diffusion coefficient D-eff is obtained by applying Fick's law to transient state using a numerical method based on finite differences. An analytical model derived from Fick's law applied to steady state is also proposed. Results give…
Sustainable design: study of the life cycle assessment of the production and packaging of wine
2003
The object of the study is the identification of the factors that interact with the environment during the production and the packaging of wine. For this aim is use an Economic Input-Output Life -Cycle assessment (EIO-LCA) and I-LCA database to access both the direct and indirect effects of supply chain on the environment and economy. In this phase is examines the impact on the environment by different types of packaging, and transport, the comparisons are made analyses energy, materials consumption and emissions in the environment.
