Olive oil has long been a popular kitchen staple. Yet producing the oil creates a vast stream of wastewater that can foul waterways, reduce soil fertility and trigger extensive damage to nearby ecosystems. Now in a study appearing in ACS Sustainable Chemistry & Engineering, scientists report on the development of an environmentally friendly process that could transform this pollutant into “green” biofuel, bio-fertilizer and safe water for use in agricultural irrigation.

On Sept. 27, NHC forecaster Daniel Brown noted, “Deep convection and banding has increased over the eastern and northeastern portion of the large circulation of Maria since yesterday.”
