“…The first generation, which is produced using food crops, accounts for the majority of the bioethanol currently produced. Examples include the United States, which makes ethanol from corn, Brazil, which makes ethanol from sugarcane, and Europe, which makes ethanol from wheat and barley [11,12]. Recent concerns about the production of firstgeneration biofuel brought about by the conflict between food and fuel have prompted field experts to look into alternate paths for biofuel production [13].…”

“…The focus has shifted to the production of second-generation biofuels because the feedstock is easily accessible and it has a less significant impact on the food web, water resources, and ecosystem due to the extensive food versus fuel debate associated with first-generation biofuels [16,17]. The current methods for making second-generation bioethanol are neither cost-effective nor environmentally friendly [12]. Therefore, the entire production process needs to be improved in order for it to be environmentally friendly and for the cost of the fuel produced to be competitive with other fuels already on the market [18,19].…”

The primary contributor to global warming has been the careless usage of fossil fuels. Urbanization's threat to the depletion of these resources has made it necessary to find alternatives due to the rising demand. Four different forms of biofuels are now available and constitute a possible replacement for fossil fuels. The first generation of biofuels is generated from the edible portion of biomass, the second generation is made from the non-edible portion of biomass, the third generation is made from algal biomass, and the fourth generation is made using molecular biology to improve the algal strain. Second generation biofuels are extremely important because they are derived from non-edible biomass, such as agricultural and agro-industrial wastes rich in cellulose, hemicellulose, pectin, and starch impregnated with lignin, and are hydrolyzed after delignification by physio-chemical or biological pretreatments using ligninases. There has been a lot of research on their production using chemical and enzymatic hydrolysis, but it has not been economically viable in comparison to first generation biofuels due to the formation of several inhibitors with chemical hydrolysis and the high cost of the enzymes. Furthermore, the need for multiple enzymes due to the various types of carbohydrates in the feedstocks makes the enzymatic process too expensive. This article examines the enzymes involved in the hydrolysis of feedstocks for the production of second generation bioethanol, a highly acceptable biofuel.

“…Out of this, the agriculture sector accounts for ∼11.1 Gt CO 2eq per y GHG emission. [23][24][25][26] With this background of the signicant impact of agricultural activities on climate change, countries participated at the Conference of Parties-26 (COP26) on 5th November 2021, as part of the discussion on agriculture and agreed on a transition toward climate-resilient sustainable food systems. It was recognized by the parties that climate-resilient agricultural practices would be crucial for ensuring food security and ending global hunger besides fullling COP26's commitment to minimizing 45% of emissions by 2030.…”

“…Бобовые культуры играют ключевую роль в устойчивой интенсификации сельского хозяйства, что делает это их вторыми наиболее культивируемыми растениями в мире после зерновых. Внедрение различных видов бобовых культур в системы севооборота имеет особое значение для того, чтобы: 1) обеспечить производство продуктов питания (главным образом, белковых концентратов и крахмалов) и кормовых добавок; 2) обогатить почвы азотом в результате его биологической фиксации; 3) снизить экологическую нагрузку на окружающую среду путем снижения объемов вносимых химических 158 удобрений, 4) снизить зараженность почв некоторыми вредителями; 5) повысить рентабельность сельского хозяйства за счет последовательного получения из одного и того же растительного сырья нескольких продуктов с высокой добавочной стоимостью [1,[4][5][6][7].…”

“…В семенах кормовых бобов по сравнению со злаковыми культурами содержится в 2, а в некоторых случаях и в 3 раза больше белковых веществ, и в то же время они имеют максимальные показатели по выходу перевареваемого протеина и незаменимых аминокислот с одного гектара. А это делает возделывание кормовых бобов выгодным с точки зрения удовлетворения возрастающих потребностей в пищевом и кормовом белке [3,4,9].…”

Отходы сельского хозяйства, не имеющие пищевой ценности, представляют особый интерес в качестве вторичных ресурсов для получения востребованных биологически активных веществ. Ежегодно в мире производится около 800 млн. тонн сухих сельскохозяйственных отходов, что приводит к проблемам загрязнения окружающей среды. Следовательно, эффективная переработка таких отходов одновременно решает и экологические вопросы, и позволяет получить продукты с высокой добавочной стоимостью из бросового сырья. В представленной работе проведено исследование химического состава водных экстрактов, полученных из створок гороха сорта «Сладкий жемчуги бобов «Русские черные, проанализирована антиоксидантная активность полученных экстрактов. Полученные результаты могут быть использованы для разработки рациональных способов переработки данных крупнотоннажных растительных отходов. Agricultural waste, which has no nutritional value, is of particular interest as secondary resources for obtaining biologically active substances in demand. About 800 million dry tons of agricultural waste are produced annually in the world, which leads to problems of environmental pollution. Consequently, the efficient processing of such wastes simultaneously solves environmental issues and makes it possible to obtain products with a high added value from waste raw materials. In the presented work, a study was made of the chemical composition of aqueous extracts obtained from the wings of pea varieties "Sweet Pearls" and beans "Russian Black", the antioxidant activity of the obtained extracts was analyzed. The results obtained can be used to develop rational methods for processing these large-tonnage plant wastes.
