(2023) Horak, Jakub; Bilan, Yuriy; Dankevych, Andrii; Nitsenko, Vitalii; Kucher, Anatolii; Streimikiene, Dalia
Sunflower is a strategic crop in the agriculture of Ukraine as it is important for food and energy production. Recently the processing of secondary products, solving the issues of waste disposal and improving the environment have been paid much attention. This is an example of a cyclic economy, as during the production of oil from sunflowers, their husk can be used for energy production. The ash obtained by burning husk is a valuable complex mineral fertilizer and can be further applied as ecological fertilizer. The aim of this article is to assess the energy and investment potential for sunflowers as an internal reserve for increasing production efficiency and reducing carbon dioxide emissions. In particular, the equivalents of energy substitution of sunflower husks for energy costs at fat-and-oil enterprises, the reduction of carbon dioxide emissions are estimated. A generalized scheme for the production of electricity from sunflower husks is considered. In particular, the use of ash from sunflower husks as a fertilizer is described. The research has shown that the sunflower husks available in Ukraine can be used more efficiently to produce electricity. Therefore policy recommendations were developed based on a study conducted

The resource and energy potential of crop biomass forms significant reserves for the economy. There are 42.3% oil, 37.4% meal, 18% husk and 0.7% sunflower oil sludge from 1 ton of sunflower. Currently, scientists are paying a lot of attention to biomass processing and improving ecology. Phosphatide concentrate and lycetin are obtained from sunflower oil sludge. Husk is a source of energy, and its energy value is 18 MJ/t. The purpose of this study is to assess the bioenergy and investment potential in agriculture. In particular, on the example of sunflower, the reserves for increasing the efficiency of electricity production. In particular, the energy cost equivalents of sunflower husk replacement of energy costs in production were estimated. The legal, organizational, and economic foundations of activities related to the prevention or reduction of waste generation have been studied. The substantiation of the necessity of including organic waste in the cycle of substances in the system “soil–plant–person” is confirmed. The need for funds for the modernization of the industry was estimated

(2024) Nitsenko, Vitalii; Dankevych, Andrii; Dzoba, Oleh; Ustenko, Andriy; Bashynska, Yulia
It is noted that in terms of sustainable development, company management should pay attention to the issues of CSR, including social and ethical values. In the international legal field, documents have been developed under the auspices of the UN regarding CSR, some of which have been ratified in Ukraine. This group of documents is optional for use by company manage ment, but affects access to international capital markets, rating and reporting transparency. Companies in the energy sector and metal rolling implement the principles, standards and norms of social and ethical business into their practice, ensuring a positive reputation and image, supporting social infrastructure and welfare of employees and the general population

У статті розглядається проблема глобальної продовольчої безпеки. Ми обґрунтували, що через вторгнення російських військ в Україну Росія може спричинити гуманітарну продовольчу кризу в деяких країнах світу. Тому війна Росії проти України – це також війна проти країн Близького Сходу та Північної Африки, які є основними імпортерами продовольства з України. Ми обґрунтували, що за нинішньої ситуації, а саме війни Росії проти України, дефіцит виробництва та експорту неминучий. Війна загрожує посівній. Ми встановили, що найбільше залежними від українського продовольства є Єгипет, Ємен, Індонезія, Бангладеш, Ефіопія, Ліван, Лівія, Пакистан та Ірак
