Re-engineering the toilet for sustainable waste water management
Article Abstract:
The present municipal wastewater treatment system is carrying a load of pollution it was never designed to accommodate. Many concerns are present, chief among them, human excretion of micropollutants. These concerns have resulted in the search for solutions, one possibility, the creation of a new toilet that could separate urine from wastewater streams.

Sorbent organic domains: discovery of a humic acid glass transition and an argument for a polymer-based model
Article Abstract:
The determination of a glass transition point for humic acid contained in soil and sediment organic matter (SOM) and the comparison of this glass transition point with those for synthetic polymers revealed the sorption tendencies of SOM macromolecules exhibiting glassy and rubbery characteristics. The implications are that environmental remediation performed over short periods of time is most effective in removing contaminants from the rubbery parts of SOM. It appears to be much more difficult to remove contaminants from the glassy SOM macromolecules.
