Red seaweed derived polysaccharides, a novel marine resource for bio-ethanol production J. Renewable Sustainable Energy 6, 033122 (2014); 10.1063/1.4880515 Multifrequency species classification of acoustic-trawl survey data using semi-supervised learning with class discovery Eutrophication combined with climate change has caused ephemeral filamentous macroalgae to increase and drifts of seaweed cover large areas of some Baltic Sea sites during summer. In ongoing projects, these mass occurrences of drifting filamentous macroalgae are being harvested to mitigate eutrophication, with preliminary results indicating considerable nutrient reduction potential. In the present study, an energy assessment was made of biogas production from the retrieved biomass for a Baltic Sea pilot case. Use of different indicators revealed a positive energy balance. The energy requirements corresponded to about 30%-40% of the energy content in the end products. The net energy gain was 530-800 MJ primary energy per ton wet weight of algae for small-scale and largescale scenarios, where 6 000 and 13 000 tonnes dwt were harvested, respectively. However, the exergy efficiency differed from the energy efficiency, emphasising the importance of taking energy quality into consideration when evaluating energy systems. An uncertainty analysis indicated parametric uncertainty of about 25%-40%, which we consider to be acceptable given the generally high sensitivity of the indicators to changes in input data, allocation method, and system design. Overall, our evaluation indicated that biogas production may be a viable handling strategy for retrieved biomass, while harvesting other types of macroalgae than red filamentous species considered here may render a better energy balance due to higher methane yields.

Актуальність. Серед головних пріоритетів державної політики є забезпечення розвитку регіонів України, що набуває важливого значення через упровадження реформи децентралізації-створення об'єднаних територіальних громад (далі ОТГ). Для забезпечення добробуту населення ОТГ мають розробляти прогнозні та програмні документи соціально-економічного розвитку відповідно до ви мог Наказу Міністерства регіонального розвитку, будівництва та житловокомунального господарства України «Про затвердження методичних

The article presents a revised draft Concept of economic development of Donetsk and Luhansk regions, on the territory of which a system of stimulating the intensification of economic processes will be introduced, which can be further implemented in other regions of Ukraine. The Concept of economic development of Donetsk and Luhansk regions was proposed for discussion in October 2020 by the Ministry of Temporarily Occupied Territories together with interested central and local executive bodies with the participation of local governments. The Concept envisages the creation of three types of priority development territories (territories of communities adjacent to the demarcation line, throughout Donetsk and Luhansk regions, on the territory of separate industrial and recreational clusters, including innovation and industrial parks, with a special regime of innovation and investment activities). Five groups of measures for the implementation of the Concept of economic development of Donetsk and Luhansk regions have been identified: improvement of regulatory policy and introduction of authentic institutional and financial instruments; industrialization of the real sector of the economy and its innovative development; development of critical infrastructure and logistics; formation of a balanced regional labor market; formation of information and communication space of Luhansk and Donetsk regions. Based on the results of the Concept implementation, it is planned to develop an appropriate Strategy and action plan. This set of regulations will allow to form a territory of priority development with a new structure of the economy and to modernize industrial production on an innovative basis, increase the share of innovative enterprises in the real sector, increase exports and the share of highly processed products, overcome logistical constraints and increase a transit region potential, increase revenues to the local budgets of the amalgamated territorial communities of Donetsk and Luhansk regions, create jobs, increase incomes, leave the youth of the regions and involve them in solving problems of economic development of Donetsk and Luhansk regions.
