  • Reducing the Economic Friction of Regulation

    Last month, we looked at two distinctly different bioenergy business models that are merging. Energy profit centers and waste cost-recovery facilities are learning the benefits of each other's business model. The resulting projects generate maximum revenue with lower production costs. The same kind of business model duality occurs in biomass energy regulation. There are more than two kinds of ...

  • Decoupling dependence on natural water: reflexivity in the regulation and allocation of water in Israel

    Since 1999, Israel has secured a decoupling between the total water supplied and water derived from the natural environment through surface and groundwater. Between 2007 and 2010, this decoupling enabled a cut of over 20% in natural water use, while maintaining overall supply volumes despite drought. By 2009–2010, natural water supply had been reduced to the levels of the early ...

  • Gray Water Characteristics and Implications on Regulations for Sustainable Water Reuse

    Different types of gray water in terms of origin (from bathing, kitchen and laundry activities) and in terms of type of source (medium and low-income residential housing and a hotel) have been studied in Gaborone, Botswana during 2004, with respect to BOD5, TSS, TP, pH, fecal coliforms and conductivity. Results show an expected high variability. No statistically significant difference was ...
