“…Thus, Harada & Inoko (1979) recommended values ranging between 60 and 80 cmol kg -1 for confirming maturity in composts from urban wastes. However, these values are in the same range as or even lower than those obtained by our group and by Reis et al (2003) and Bustamante et al (2008b), in yet-noncomposted wine industry wastes.…”

“…When measuring the content of these substances in composts from wine industry wastes, Patti et al (2004) reported a humic and fulvic acids low content, as opposed to high contents (above 60%) of humines. The final values of CEC were in the same range as those obtained by Reis et al (2003), although definitely lower than the ones obtained by Bustamante et al (2008b) with different mixtures of GS, GM, DM and manures. Even though the CEC measured by Harada & Inoko (1979) has been accepted as an indicator of compost maturity, its optimal value depends to a great extent on the nature of wastes.…”

To study the process of composting of grape marc and test the resulting compost as a substrate for the cultivation of ornamental plants, six composting processes, with mixtures of dealcoholised grapevine marc and grape stalk (DM + GS) in a 1:1 ratio (v:v), were carried out in Seville (Spain) between 2000 and 2006. The duration of the composting ranged between 20 and 24 weeks in the Spring-Summer season. Weekly, temperature, pH, EC, N-NO 3 -and N-NH 4 + , were measured. The maximum temperatures reached values of 65-73°C at a depth between 40 and 80 cm. The compost had a slightly alkaline pH, slightly salinity, high organic matter and total nitrogen contents. The final compost chemical composition in total elements showed values in the same range as those corresponding to plant material, except for Fe. The distribution in the size of the particles gives way to a total porous space that is close to the one considered as optimal in a substrate for soilless cropping. Pore size distribution showed a prevalence of big pores that produces unbalance in the water-air ratios, resulting in a material with a good aeration but with low water retention. The composts were tested as substrates for four ornamental species: geranium, petunia, carnation and gerbera. The results suggest that compost has no limiting characteristics for its use as a medium for the cultivation of ornamental plants in container, and can replace conventional substrates, such as peat and coconut fibre.Additional key words: compost; grape marc; growing media; soilless culture. ResumenCompostaje de residuos de la industria vinícola y su uso como sustrato para el cultivo sin suelo de plantas ornamentales Para estudiar el proceso de compostaje de orujos de uva y probar el compost resultante como sustrato para el cultivo de plantas ornamentales, se llevaron a cabo, en Sevilla (España) entre 2000 y 2006, seis procesos de compostaje, con mezclas de orujos de vid desalcoholizados y tallos de vid o raspón (DM + GS) en una proporción 1:1 (v:v). La duración del compostaje osciló entre 20 y 24 semanas en el período de primavera-verano. Se midieron semanalmente temperatura, pH, CE, N-NO 3 -y N-NH 4 + . Se alcanzaron temperaturas máximas de 65 a 73°C a 40-80 cm de profundidad. El compost resultante tenía pH ligeramente alcalino, moderada salinidad, altos contenidos en materia orgánica y nitrógeno total. Los análisis químicos del compost mostraron niveles de elementos totales en igual rango que los correspondientes a material vegetal, excepto Fe. La distribución del tamaño de partículas del material origina un espacio poroso total cercano al considerado óptimo en los sustratos para cultivo sin suelo. La distribución del tamaño de poros mostró una prevalencia de poros grandes, circunstancia que produce un desequilibrio en las relaciones aire-agua, dando como resultado un material con buena aireación, pero con baja retención de agua. Los composts se probaron como sustratos para cuatro especies ornamentales: geranio, petunia, clavel y gerbera. Los resultados no sug...

“…Now, the alternative uses of these residues allow to include energy production via anaerobic digestion or incineration, the spreading on agricultural land (raw or composted), and the use as a raw material for the production of cosmetics and pharmaceuticals goods. The use of wine industry residues in agriculture and on the beneficial effects of the composts as organic fertilisers and in soil amendments has been widely studied over ten years by many researchers (Bertran et al, 2004; Bustamante et al, 2009;Carmona et al, 2012;Díaz et al, 2002;Moldes et al, 2007;Reis et al, 2003;Ruggieri et al, 2009). The use of the untreated grape marc for the production of energy from biogas, in co-digestion with other biomass, allows to obtain environmental and economic benefits (Amon et al, 2009;Celma et al, 2007;Dinuccio et al, 2010;Fountoulakis et al, 2008;Moletta, 2005;Schievano et al, 2009).…”

The choice of grape marc as biomass to produce energy has a double purpose. It provides a valid alternative to the handing over to distilleries, which represents a considerable cost for the community and also gives value to a form of agricultural-industrial waste. In this paper, the results of an experiment performed at ERSAF (Lombardy) in their laboratories in Mantova are assessed. A laboratory scale plant was used in order to evaluate the biogas and the methane produced by the anaerobic digestion (AD) of fresh grape marc and to evaluate the role of seeds in the production of methane. The results indicate there have get yields of up to 110 Nm 3 /t sv of methane, with a much faster production rate than with other bio-masses. The inclusion of grape seeds has a positive effect on the production of biogas and methane. With crushed grape marc a higher percentage of CH4 could be reach than to the other tests, suggesting that the grape seeds crushed favours the methanogenesis. Nevertheless the differences between this matrix and that with as such grape marc are not statistically significant.
