“…Agricultural by-products such as straw, pruning residues and other agricultural residues are a promising low-cost resource for pellet production (Mediavilla et al, 2009;Carone et al, 2011;Miranda et al, 2011;Chico-Santamarta et al, 2012;Liu et al, 2014). Among other biomass, vineyard-pruning residues represent a potential worldwide source of energy (Spinelli et al, 2012;Picchi et al, 2013).…”

Nowadays many types of biomass are studied to satisfy the increased demand of renewable energy based on pellet combustion. However, only a few biomasses fulfil the high quality standard required for pellet used in domestic appliances. European and International standards in force define this quality of non-industrial use of pellets in term of the origin of biomass, physical, mechanical and chemical parameters. Vineyard residues are a worldwide potential source of energy but their compliance to be used in domestic pellet stoves has not been yet proven according to the new standards in force. In order to meet this need, this study makes an exhaustive characterisation of vineyard based pellets manufactured from residues of Prosecco (Glera variety) vineyards, assessing both the quality of biofuel and its behaviour during combustion in a domestic pellet stove. The quality of biofuel has been evaluated according to the in force standards for wood and non-woody pellets. The results show that vineyard pellets do not meet the type B quality standards required for non-industrial use of wood pellet mainly because of the high amount of ash content (>2%) and the high amount of copper (>10 ppm) but they fulfil the specifications of the type B non-woody pellets. Furthermore, during combustion test of vineyard-based pellet the high emission of CO indicates incomplete combustion; and vineyard-based pellet NOx emissions are more than double compared to those obtained during the control tests, confirming that the analysed vineyard-based pellets are unsuitable, as they are, for use in traditional pellet stoves.

“…Grape pomace has so far been investigated as a fertilizer or soil conditioner [10][11][12][13] , as biomass for biofuel production [14][15][16] and as animal feed [17][18][19][20] . Wet grape pomace is a highly perishable material subject to uncontrolled microbial spoilage owing to its high moisture content (~60 % wb ) and water activity.…”

“…Sladký et al (2002) states that marc is responsible for better cohesiveness of pellets and prevents the breakdown of the material during the pressing process thanks to the cellulose content in the skins. Annamalai et al (1987) and Miranda et al (2011) state that with increasing share of marc in pellets, the ash content decreases. On the other hand, pellets with higher marc content show higher values of fi xed carbon.…”

“…Prozil (2012) states that biomass from forestry and agriculture is fi nding use as an alternative energy source mainly in household heating and electricity production. In recent years, attention is being directed more and more towards the use of waste biomass from viniculture and wine-making, which represent a signifi cant production sector in the EU (Freppaz et al, 2004;Baydar et al, 2007;Miranda et al, 2011). Waste products produced regularly every year in large amounts include vine shoots a er winter cutting of grapevine and marc produced during grape processing (Walg, 2007;Tangolar et al, 2009).…”

The contribution describe the possibilities of using marc for manufacturing pellets for energy purposes. Experiments associated with pellet production were performed in several variants. Biomass pellet variants consisted of diff erent percentages of vine shoots from vineyards, as well as marc and hay. These test variants were measured for their calorifi c value, which ranged between 17.36 and 19.21 MJ.kg −1. Bulk density was also determined, ranging between 619.27 and 630.9 kg.m −3. Pellets produced with marc content were also tested for mechanical durability, which was between 96.15 and 96.82% for the test variants. The calorifi c value, alongside other parameters assessed, shows favourable characteristics towards use in combustion processes. The results obtained show that in terms of the parameters analysed, marc pellets could be an attractive commodity for combustion.
