Physicochemical Dynamics of Composting Screw Pressed Cattle Slurry Amended with Italian Ryegrass Straw or Gorse Bulking Agents

“…In Portugal, other plant materials, traditionally used as livestock bedding, such as gorse or furze (Ulex europaeus L.), may also have potential use as bulking agents. In Portugal and Spain, this branched shrub has become a serious, highly invasive weed problem (Richardson and Hill 1998), where it also represents a significant fire risk (Nunez-Regueira et al 2004). However, the application of gorse as a bulking agent for composting biowastes, such as SF, has not been previously described in the literature.…”

Extraction of phenolics from broom branches using green technologies

“…They have been proposed as a potential high quality feeding resource for grazing ruminants, particularly during dry seasons . Alternative uses for the management of the excess of shrub species based on the energetic exploitation of this resource for production of electric energy were proposed …”

“…11,12 Alternative uses for the management of the excess of shrub species based on the energetic exploitation of this resource for production of electric energy were proposed. 13 Autohydrolysis processing of broom branches with hot compressed water has been proposed to produce a solid-containing fraction mainly made up of cellulose and lignin and a liquid phase containing sugar oligomers derived from hemicelluloses. The solid phase was used for manufacturing polylactic acid based biodegradable composites, and the sugar oligomers in the soluble fraction could be suitable as prebiotic agents.…”

Caracterización Bioenergética de los Residuos de Cosecha de las Principales Especies Forestales del Noroeste de España

“…Dopazo et al, 2008, 2009, Vega et al, 2010. A pesar de este potencial de energía biomásica, los estudios de calidad de biomasa en la región son relativamente limitados (Nunez-Regueira, 1996, 1997, 1999, 2004, Pérez et al, 2008, Gómez et al 2014. Los estudios disponibles se han centrado en la variación estacional de poder calorífico y cenizas de especies arbóreas y matorrales (Nunez-Regueira, 1996, 1997, 1999, 2004, Pérez et al, 2008, no existiendo sin embargo ningún estudio en la región que haya realizado un análisis estadístico de la variación de estos parámetros entre las principales especies arbóreas, similares a los trabajos realizados en otras regiones de España (Elvira y Hernando, 1989, Gillon et al, 1997 o en Portugal (Lousada et al, 2010, Telmo y Lousada, 2011a, 2011b.…”
