Grape pomace (GP) is a low-value by-product that contains a significant amount of high value-added products. The huge amount of non-edible residues of GP wastes (seeds, skins, leaves and, stems) produced by wine industries causes' environmental pollution, management issues as well as economic loss. Studies over the past 15-20 years revealed that GP could serve as a potential source for valuable bioactive compounds like antioxidants, bioactive, nutraceuticals, single-cell protein, and volatile organic compounds with an increasing scientific interest in their beneficial effects on human and animal health. However, the selection of appropriate techniques for the extraction of these compounds without compromising the stability of the extracted products is still a challenging task for the researcher. Based on the current scenario, the review mainly summarizes the novel applications of winery wastes in many sectors such as agriculture, pharmaceuticals, cosmetics, livestock fields, and also the bio-energy recovery system. We also summarize the existing information/knowledge on several green technologies for the recovery of value-added by-products. For the promotion of many emerging technologies, the entrepreneur should be aware of the opportunities/techniques for the development of high-quality value-added products. Thus, this review presents systematic information on value-added by-products that are used for societal benefits concerning the potential for human health and a sustainable environment.
葡萄皮渣（GP）是一种低价值的副产品，却含有大量高附加值产品。葡萄酒产业产生的大量葡萄皮渣废弃物（种子、果皮、叶子和茎）不可食用，会造成环境污染、管理问题以及经济损失。过去15至20年的研究表明，葡萄皮渣可作为抗氧化剂、生物活性物质、营养保健品、单细胞蛋白和挥发性有机化合物等有价值生物活性化合物的潜在来源，人们对其对人类和动物健康的有益影响的科学兴趣与日俱增。然而，选择合适的技术来提取这些化合物而不影响提取物的稳定性，对研究人员来说仍是一项具有挑战性的任务。基于当前情况，本综述主要总结了葡萄酒厂废弃物在农业、制药、化妆品、畜牧领域等多个行业的新应用，以及生物能源回收系统。我们还总结了有关几种绿色技术回收高附加值副产品的现有信息/知识。为推动许多新兴技术的发展，企业家应了解开发高品质高附加值产品的机会/技术。因此，本综述提供了关于高附加值副产品的系统信息，这些副产品用于关乎人类健康潜力和可持续环境的社会福利。
