Harvard Papers in Botany

We present a revision of all the species and available names of Eriopsis, a long misinterpreted genus of Orchidaceae described by John Lindley in 1847. A new species from the Venezuelan Guayana, E. escalerensis, is described and illustrated. An additional species from the Andes is circumscribed morphologically and geographically, but it remains undescribed until further data are available. A key to identify all the seven recognized species, conservation assessments in accordance with the B set of criteria of the IUCN, and miscellaneous notes are also provided. © President and Fellows of Harvard College, 2015.

Waste Management and Research

The final products of the ethanol industry are alcoholic beverages, industrial ethanol and biofuels. They are produced by the same production process, which includes fermentation and distillation of raw materials which come from plant biomass. At the end of the distillation process a waste effluent is obtained called vinasse or stillage. The direct disposal of stillages on land or in groundwater (rivers, streams or lakes), or even for the direct irrigation of crops, pollutes the environment due to their high organic contents, dissolved solids and many other compounds which are toxic or could be contaminants under certain environmental conditions. This work reviews the characterization of vinasses from different feedstock sources and the main treatments for conditioning the soluble solids of vinasses before their disposal. © 2011 International Solid Waste Association.
