“…Consequently, the distillate produced can be marketed, with numerous spirits with different names being produced around the world [15,16]. Other exploitation methods include its use as a fertilizer or as animal feed [17,18]. However, all these valorization methods present several drawbacks, the major of which is failing to exploit the full market potential of GP [19].…”

Grapes are cultivated globally with the total area under vines reaching 7.4 million hectares in 2018, and the global wine market is expected to increase to USD 423 billion by the end of 2023. However, winemaking produces large quantities of by-products/wastes like grape pomace (GP; the residue of pressed grapes), wine lees (WL; the residue accumulating in vessels containing wine after fermentation), and vine shoots (VS; generated during the pruning season in the vineyard). Exploitation of agro-industrial side-streams, wastes, and residues, such as WL, GP, and VS, is an issue of vital importance to global good environmental governance. As WL and GP constitute valuable sources of nutrients and VS are a source of cellulose fibers, their use for novel products with applications in winemaking is of major importance. In the present study, the recent trends in sustainable exploitation of such by-products for application in winemaking are presented. WL consist mainly of ethanol, tartaric acid, and yeast cells, and it is usually used for the recovery of these bioactive compounds and as a nutrient supplement of lactic acid bacteria and yeasts growth. GP has been used for the recovery of phenolic compounds, as a substrate for alcohol production, and as fertilizer in the vineyard. New trends include its use for eliminating unwanted wine compounds (like ochratoxin A and pesticides) and as a sustainable fining agent of wines (in order to modify its sensory features such as astringency, bitterness, and mouthfeel). Finally, VS has been used as biochar and for nanocomposite film production.

“…Generally, there were significant differences for almost all factors among compost from different piles, even for those coming from the same mixtures (p<0.05). Temperature is one of the most significant factors for assessment of composting processes, because it affects the sanitation capability and microbial activity of the process (Salgado et al 2019). As a result of high moisture content and anaerobic conditions, the maximum temperature in TW0 and TW1 was just 37°C; consequently, these piles did not reach the thermophilic phase and their data were not shown.…”

Abstract. Nafez AH, Nikaeen M, Hassanzadeh A, Kadkhodaei S. 2020. Changes in microbial populations during co-composting of dewatered sewage sludge with pruning wastes in windrow piles. Biodiversitas 21: 4648-4655. The aim of this paper was to study the composting of sewage sludge (SS) and pruning waste as bulking agent with regard to abiotic factors and succession of functional microbial groups. To prepare the composting piles bulking agent and SS in volumetric ratios of 1:1 (TW1), 2:1(TW2), and 3:1(TW3) were used, and a pile of raw sludge was used as control. Samples for investigation were obtained from the composting piles at time intervals of 5-7 d. The temperature of the control pile and TW1 was just 37°C and did not reach the thermophilic phase. The number of thermophilic bacteria increased to 14 log CFU gDW-1 in the thermophilic phase. The salmonella was lost on the 47th and 19th days of the composting process, for TW2 and TW3, respectively. There was a significant correlation between mesophilic fungi with mesophilic bacteria (r=0.942, P<0.001). The majority of the microbial populations inspected revealed their maximum numbers towards the end of the thermophilic phase, with decreasing tendencies afterward. The number of evaluated microorganisms was controlled by differences in physicochemical parameters at different composting phases. The results revealed that the scheduling of the thermophilic period, as well as the microbial community and environmental situations, affects the microbial structure andTW2 had the best quality compared to other piles in achieving the best thermophilic phase and elimination of pathogenic microorganisms.

La predominancia orgánica de los Biorresiduos (BOM) presentes en los Residuos Sólidos Municipales, favorece su aprovechamiento mediante estrategias como el compostaje; sin embargo, presentan deficiencias que pueden ser mitigadas con la incorporación de materiales acondicionadores. En este estudio se evaluó el efecto de la incorporación de Pasto Estrella (PE) como material de soporte, sobre el compostaje de BOM (proporciones BOM:PE A1 90:10, A2 80:20 y A3 70:30), evidenciándose efectos favorables. A2 mantuvo las mayores temperaturas; A2 y A3 registraron la mayor reducción de sólidos volátiles (SV) y concentración final de nitrógeno total (NT). Los productos finales de A2 y A3 también presentaron mejor calidad en términos de capacidad de intercambio catiónico, contenido de nutrientes (fósforo, potasio y nitrógeno totales), densidad aparente, capacidad de retención de humedad y contenido de materia orgánica, siendo el producto de A2 el de mayor valor agronómico, de acuerdo con la Norma Técnica Colombiana 5167.
