“…Absolute priorities are energy-saving [3,4] with the simultaneous development of renewable energy [5,6]. The next set of challenges concerns the economic use of resources such as water [7,8], forests and plants as a source of medicines and other substances [9,10], the comprehensive implementation of green chemistry technologies [11,12]. Last but not least, it is to solve the problems of utilisation and processing of waste from various industries and reduce industrial carbon emissions [13,14].…”

Textile and clothing industries generate a lot of waste at both production stages and in the process of wearing garments. Every inhabitant of developed countries annually wastes up to 30 kg of used but still suitable clothes, which decompose very slowly in natural conditions. The broadest possible implementation of textile waste processing technologies, such as downcycling and upcycling, is the key to ensuring the successful operation of the textile and clothing industries under conditions of sustainable development. The paper goal is to determine factors controlling students’ upcycling behaviour to strengthen the educational components and meet sustainable development challenges for the garment industry. Based on interpersonal and planned behaviour models, 93 students of 1-6 years majoring in clothing technology, design and sectoral professional education were surveyed to understand their upcycling behaviour. The surveyed students are divided into similar-sized groups of optimists (practice upcycling more than once every three months) and pessimists (less than once a year). Upcycling behaviour was shown to correlate with intentions, which are, in turn, affected by social factors, attitude, and perceived behaviour control. Perceived habits and facilitating conditions have a relatively small impact. There is almost no difference between students of different years of study and specialities. Students’ understanding of the benefits of upcycling is shallow and does not change with training years. Amid a highly-positive attitude towards upcycling, a low level of knowledge of the benefits and lack of progress with years indicate existing problems in developing upcycling behaviour in the learning process.

“…Fundamental transformations are taking place and are yet to take place in terms of the effects of economic activity on the environment. These are the development of renewable energy [2,3]; energy-saving [4,5]; improvement of water supply and water treatment [6,7]; spread of green chemistry technologies [8,9]; widespread use of natural medicines [10,11] or the development of new drugs from natural raw materials [12].…”

By surveying 95 students studying design and technology in the light industry, the problems in mastering upcycling technologies were explored, and ways to overcome them were outlined. The analysis of existing problems is carried out at three levels - personal perception of upcycling, the formation of relevant skills and knowledge and lack of experience in scaling personal expertise to a business startups level. All respondents are roughly divided into those who practice upcycling frequently and those who do it occasionally. Another 15% of respondents did not decide on their preferences. Respondent attitude, control of behaviour, and behavioural intentions are the most influential factors that encourage upcycling. The influence of social factors, perceived habits and the presence of facilitating conditions is more moderate. Interviewed students have a poor understanding of the benefits of upcycling. Competence for creativity, which is key to mastering upcycling techniques, is absent in educational and professional programs in technology and design. Several examples of possible changes in curricula from 4 disciplines aimed at the formation of creativity are given. The main reasons that complicate the scaling of acquired skills and knowledge in developing business startups with upcycling are analysed. An example of a designed startup is given.

Мета роботи. Визначення вмісту біологічно активних речовин та елементного складу трави звіробою різних виробників, виявлення кореляцій між вмістом АФІ та мікроелементним складом трави. Матеріали і методи. У дослідженні використано стандартні зразки органічних речовин виробництва фірми Fluka, стандартні зразки іонів металів виробництва СКТБ фізико-хімічного інституту імені О. В. Богатського НАН України, зразки звіробою трави різних виробників. Аналітичне обладнання: спектрофотометр Hewlett Packard 8452A, рідинний хроматограф Shimadzu LC-20, обладнаний УФ-детектором, з використанням колонки Phenomenex Luna C18, атомно-абсорбційний спектрофотометр Solaar S4 AA (Thermo Electron Co., США). Статистичні розрахунки здійснено з використанням пакету статистичних програм IBM SPSS-19. Результати й обговорення. Досліджено вміст біологічно активних речовин (гіперицин, гіперозид, рутин, кверцетин, хлорогенова, неохлорогенова, розмаринова та кофейна кислоти) та елементний склад зразків трави звіробою чотирьох різних виробників. Зареєстрована суттєва варіація вмісту органічних речовин. Наприклад, концентрація гіперицину, що є одним з основних активних фармацевтичних інгредієнтів звіробою, змінюється у 2-5 разів. Встановлено статистично значущі позитивні або негативні кореляції між концентраціями деяких елементів (K, Mg, Fe, Mn, Cd) та вмістом органічних речовин (рутин, гіперозид, гіперицин та гідроксикоричні кислоти). Висновки. Вміст біологічно активних речовин, а саме гіперицину, рутину, гіперозиду, досліджених гідроксикоричних кислот, суттєво змінюється в залежності від походження та елементного складу зразків трави звіробою.
