“…However, it should be remembered that the emissions generated during the combustion of fuels containing biomass are related both to the process parameters during combustion and the type of biomass that is used as biofuel [11][12][13]. The implementation of low-emission economy principles is a long-term process, requiring many new investments and thus involving significant financial outlays [14,15], which is why in the countries where energy is still produced mainly on the basis of burning minerals a good solution is the introduction of composite fuels consisting of both biomass and non-renewable fuels. The consumption of such fuel pollutes the environment to a lesser extent, thus contributing to the goals of a low-emission economy [6,16].…”
The paper presents the possibility of managing forest and agricultural biomass for energy purposes in the aspect of environmental protection and sustainable development. The results of experimental studies of physicochemical properties of four types of plant biomass, i.e., a wheat straw, oat grains, larch needles and rapeseed pods are shown. The study consisted of determining the energy parameters in the form of gross and net calorific values of the test material. In addition, the ash and moisture content of the material was tested. Moreover, an elementary analysis for the tested materials by determining the content of carbon, hydrogen and nitrogen was performed. The studies have shown energy potential for the examined materials, in particular oat grains, where the gross calorific value amounted to 17.16 MJ·kg −1 , net calorific value to 15.37 MJ·kg −1 and ash content to 2.71%. Larch needles are characterised by the highest carbon content of 45.73%, oat grains by hydrogen at 6.53%, 1.53% nitrogen and sulphur 0.11%. Determined emission rates indicate a reduction of 31-41% CO, 30-39% CO 2 , 22-55% NO x , 95-97% SO 2 , 47-97% dust depending on the type of used biomass in relation to hard coal.

Section: Res Can Be Classified By Type Of Energymentioning
The topic of this article is very relevant, since the issue, concerning the level of environmental pollution by harmful emissions arose recently. The purpose of the article is to assess the situation from the point of view of the energy economy in the Chechen Republic. The task is to analyze of various options for the use of non-traditional (alternative) energy sources in the Chechen Republic. The article also provides an overview of proposals that promote the development of alternative energy. This article allows drawing a conclusion about feasibility of using alternative energy sources.
“…Nevertheless, their agro-product supply chains usually have low eco-efficiencies, which leads to less utilization of agro-waste, thus having an impact on the formulation of reverse logistics [4,5]. As these agro-wastes generally contain large amounts of biomasses, recycling them for energy recovery may yield greater economic and environmental benefits [6][7][8]. However, the incorporation of bioenergy enterprises into the supply chain inevitably disturbs supply chain operations.…”
This study redesigns the supply chain of agricultural products in southwest China under the Belt and Road Initiative to improve its eco-efficiency by considering the associated agro-wastes flowing into bioenergy enterprise for energy production. Two scenarios are created, in which the first assumes that all waste flows into the enterprise, whereas the second only considers the inflow of agro-waste produced by farmers and the wholesale market. A system dynamics simulation is conducted by using carbon emissions per product as an indicator to obtain the optimal scenario for managerial practice and design an incentivizing mechanism to drive supply chain operations. A case study is provided to demonstrate application of the system dynamics. Finally, the limitations of the study are discussed to lay the foundation for further improvement.
