  • Technico-economic assessment of groundwater treatment by palladium-on-zeolite-catalyst in comparison to GAC fixed bed adsorbers

    A technico-economic comparison between palladium-on-zeolite (Pd/Y), and granular activated carbon (GAC) based methods of groundwater clean-up is presented. The treatment concepts are assessed by means of process-based cost functions that can be applied to a broad range of case-specific conditions. The analysis accounts for variability in cost and performance parameters and reduces the interplay ...

  • Market transformation: can washing machines really help clean up surfing?

    The culture of surfing is awash in environmentalism. It has soul, it's connected to the natural rhythms of the earth, it has icons like Jack Johnson singing about reducing and reusing. Beneath the mythical veneer, however, the business of surfing (worth $7 billion annually) is big business. So it has all the usual problems - and then some - as it looks to live up to its eco-friendly image. Most ...
