“…The impact of renewable sources on global climate change mitigation has been widely recognized [62,73,74]. Renewable sources are not perfect and have some disadvantages, such as higher investment costs, less reliable technology, and issues with the consistency of the energy supply [75]. Therefore, it is necessary to support innovations in the field [53].…”

The increasing popularity of social media worldwide provides us with an opportunity to understand social, cultural, and environmental issues about people’s perception of sustainability. The article aims at identifying the main topics of communication related to hashtag # sustainability based on a communication analysis on the Twitter network. We investigated the perception of sustainability using data from 414,926 Twitter interactions by 223,476 users worldwide. The data were recorded between April 17, 2018 and July 12, 2019. We identified Innovation, Environment, Climate Change, Corporate Social Responsibility, Technology, and Energy as key hashtags in the field of sustainability. In conjunction with this, we identified the six following communities: (1) Environmental Sustainability, (2) Sustainability Awareness, (3) Renewable Energy and Climate Change, (4) Innovative Technology, (5) Green Architecture, and (6) Food Sustainability. The usage of these communities is applicable in marketing communication as well as in the Corporate Social Responsibility activities of the given companies. The results of the analysis give the organizations a possible direction for their sustainable business model improvement via the contribution of society´s voice.

Abstract. Intense development of research equipment leads directly to increasing cognitive abilities. However, along with the raising amount of data generated, the development of the techniques allowing the analysis is also essential. Currently, one of the most dynamically developing branch of computer science and mathematics are the Artificial Neural Networks (ANN). Their main advantage is very high ability to solve the regression and approximation issues. This paper presents the possibility of application of artificial intelligence methods to optimize the selection of cosubstrates intended for methane fermentation of chicken manure. 4-layer MLP network has proven to be the optimal structure modeling the obtained empirical data.

“…The result shows that the heat generated by AD can basically maintain 35°C temperature condition in actual biogas engineering, while the experimental condition at 50°C needs to provide external heating. 39 Compared with the condition of 35°C, the total output of biogas at 50°C is only increased by about 10%. Therefore, from the point of view of engineering application, the temperature condition of 35°C may be more advantageous.…”

Anaerobic digestion (AD) of livestock and poultry manure to produce biogas can not only improve environmental problems, but also effectively utilize waste. In order to maximize the resource utilization of livestock and poultry manure, the AD experiments of mixing cow dung, deer manure, and mushroom fungus were carried out. The changes of AD biogas production (daily and cumulative biogas production), CH4 content, volatile fatty acids (VFAs), pH at different temperatures (20, 35, and 50°C), and mixing ratios were studied, and the optimum reaction conditions were discussed. Results show that with the increase in temperature the biogas production rate and the cumulative biogas production at each proportions increase. At 20°C, the amount of biogas generated is very small. Under different proportions of raw materials, the cumulative biogas production first increased and then decreased. The best biogas production is at a temperature of 50°C and a proportion of cow dung, deer manure, and mushroom fungus is 0.3:0.4:0.3. The unit total solid biogas production rate reached 0.23 L·g−1. The mixed fermentation of livestock manure and mushroom fungus made up for the inadequacy of its separate fermentation performance and was also an effective method to improve the biogas rate and comprehensive utilization rate of livestock manure. The results of this study are of great significance in promoting the utilization of livestock and poultry manure.
