“…The total Zn content was relatively similar in all of the samples studied (skins and seeds, Tables and ) with values ranging from 12.0 to 19.1 μg g −1 , except in distilled skins of the Treixadura white variety (25.8 μg g −1 ). Similar Zn values were found in other winery wastes . In general, micronutrient content obtained in all grape pomace samples that were analyzed in this work were lower than those found in other organic fertilizers used for agricultural soils, as well as in domestic sewage sludges and other animal manures …”

“…The main residues produced during the winemaking process are grape stalks (GS), distilled and undistilled grape pomace (GP), wine lees (WL), winery wastewater (WW), and winery sludges (WS) . To minimize the environmental impact of these residues, several recycling alternatives have been developed, such as the use of GP for the extraction and recovery of phenolic compounds, the production of grape seed oil, and their use as organic fertilizers or amendments for soils by both direct application or after composting . These residues usually have an elevated nutritional value associated with their high organic matter content and macronutrients, especially K .…”

BACKGROUND The possible agricultural use of grape pomace could be limited by the content and mobility of metals. This is influenced by many factors. In this study, the abundance and availability of heavy metals and essential nutrients were evaluated comprehensively in different grape pomace residues from winemaking of five white and red grape varieties, before and after the distillation process. RESULTS The total metal content found in grape pomace skins and seeds confirmed that there was greater metal accumulation in skins than in the corresponding seeds, with the exception of Ca and Mg. The enrichment of all metals (except K) during the distillation stage was confirmed by means of a significant correlation (R = 0.996, P < 0.001) between the metal content obtained in distilled and undistilled samples. Regarding availability, multivariate statistical analysis showed different behavior among elements, but a great similarity for metal mobility in both distilled and undistilled grape pomace samples and in both skins and seeds, except for Mn, Zn and Mg. CONCLUSION The results obtained in this study suggest the potential application of these grape residues as organic fertilizers for agricultural soils, without limitations resulting from heavy metal contamination. © 2019 Society of Chemical Industry

“…have tested a high linear correlation that exists between the aerobic and anaerobic biodegradability of substrates, making the aerobic test an adequate way to evaluate the feasibility of a substrate to be degraded. Therefore, grape marc waste is susceptible to being valorized by a biological treatment instead of being landfilled, as reported previously by Hungría et al . In addition to these results, Lim et al .…”

BACKGROUND Grapes are one of the largest crops produced worldwide and are used mainly to produce wine, which generates a large volume of waste. Certain designations of origin, such as the Montilla‐Moriles PDO of Cordoba (Spain) produce liqueur wines at low yield. The possibility of generating by‐products from the waste during the winemaking process might provide an additional economic input. RESULTS Anaerobic digestion of grape marc waste derived from the Pedro Ximénez variety (ecological crop) was evaluated under mesophilic conditions at laboratory scale. The loads added to the reactors varied from 0.50 to 1.25 gVS (volatile solids) L−1, with an average methane production coefficient of 252 ± 31 mLSTP CH4 g−1 VSadded (STP: 0 °C, 1 atm). The highest methane rate production was found to be 47.97 ± 4.29 mLSTP CH4 L−1 h for 1.25 gVS L−1 of grape marc waste. The volatile fatty acids concentration increased, and the pH and alkalinity slightly decreased over the experimental time. Moreover, the digestate contained lower metal concentration in comparison with waste derived from nonecological crops. CONCLUSION Anaerobic digestion of Pedro Ximénez grape marc waste is feasible and might be implemented for waste management, thus reducing the large volume of waste generated. © 2018 Society of Chemical Industry

“…After that, an integrated, intelligent and planned approach for the waste management is necessary [24]. Elements of attention, recommendations and risks while tackling this issue are suggested by the literature and the current practice [25,26]. Among them, OW treatment is crucial, because of the nature of OW and environmental, social and safety reasons [27].…”

Biogas Micro-Production from Human Organic Waste—A Research Proposal

et al. 2018

Organic waste (OW) management tackles the problem of sanitation and hygiene in developing countries and humanitarian camps where unmanaged waste often causes severe health problems and premature death. OW still has a usable energy content, allowing biogas production, potentially contributing to satisfy the local needs, e.g., cooking, lighting and heating. Digesters are the devices converting OW into biogas under anaerobic conditions. They are simple and effective solutions for the OW management in rural areas, humanitarian camps and remote developing regions, producing energy and fertilizers for local farming as residual. This paper describes the design and lab-test of a domestic OW management system integrating a waterless toilet with a small-scale digester producing safe biogas for local micro-consumption. Starting from people's needs and an extensive review of the current state-of-art technology, the proposed system's key innovation and strength is the combination of effectiveness and a very simple construction, set up and use, fitting with the rural conditions and raw materials available within the emerging countries. A small-scale prototype is assembled and lab-tested assessing the quantity-i.e., productivity-and quality-i.e., composition and methane content-of the produced biogas. The measured productivity in terms of specific biogas production (SBP) is of about 0.15 m 3 /kg SV and a methane content of about 74% in mass match the energy needs of domestic users, encouraging the spread of such systems in developing regions and rural areas.
