Abstract
Purpose. Modelling environmentally safe bioenergy trends based on national and international patent databases and scientific databases. Methods. Bibliometric method of analysis using the Scopus database and patent databases, modeling methods using a special visualization software package. Results. An analytical diagram based on the review of patent databases was developed, as well as a model for visualization of interrelationships between clusters of bioenergy development trends as a complex solution for environmental protection. Thus, 4 clusters were formed based on data from the Scopus database using VOSviewer software: 1) cluster (red) reveals the environmental problems of changing the direction of implementation of stationary energy sources with the development of bioenergy potential, and the creation of strategies for this development at the level of regions; 2) cluster (yellow) covers the process of restoration of ecological systems, in particular forests and reduction of CO2 emissions from bioenergy; 3) cluster (green) covers the production and use of different types of fuel and energy produced by the introduction and improvement of bioenergy technologies; 4) cluster (blue) covers the impact of bioenergy technologies on environmental restoration and purification and reduction of damage from anthropogenic impact. Conclusions. The analysis of patent databases with cluster visualization based on a bibliometric approach allowed to identify the most promising areas of research in the field of bioenergy solutions development. Further research will be focused on the development of a lab bench for biogenic gas production with the possibility of complex processing of secondary raw materials and obtaining environmentally safe digestates.
Highlights
The greenhouse effect of increasing carbon dioxide content in the atmosphere is the result of the long-term use of traditional non-renewable energy resources
The purpose of this study is to model environmentally safe bioenergy trends based on national and international patent databases and scientific databases
The issue of waste recycling in urban areas is very relevant; the development of renewable energy sources is essential to increasing environmental safety in the regions and green economy stimulation
Summary
The greenhouse effect of increasing carbon dioxide content in the atmosphere is the result of the long-term use of traditional non-renewable energy resources Global production focuses on the development of energy-efficient and environmentally friendly technologies in all areas of human activity to solve existing problems related to the depletion of traditional non-renewable energy natural resources, environmental pollution, and population growth. Such technologies involve renewable energy sources, including biomass energy generated by livestock and agricultural waste, wood waste, plant biomass, marine phytoplankton plantations, and photobioreactor products [1, 5]
