Environmental pollution is defined as “the unfavorable alteration of our surroundings through direct or indirect effects on the chemical, physical, and biological characteristics of our air, land, and water influenced primarily by man's actions. Some of the major variables, elements of the problem, and problems related to farm animal waste management can be found in Table 1.

Biogas is an alternative to gaseous biofuels and is produced by the decomposition of biomass from substances such as animal waste, sewage sludge, and industrial effluents. Biogas is composed of methane, carbon dioxide, nitrogen, hydrogen, hydrogen sulfide, and oxygen. The anaerobic production of biogas can be made cheaper by designing a high throughput reactor and operating procedures. The parameters such as substrate type, particle size, temperature, pH, carbon/nitrogen (C/N) ratio, and inoculum concentration play a major role in the design of reactors to produce biogas. Multistage systems, batch, continuous one-stage systems, and continuous two-stage systems are the types of digesters used in the industry for biogas production. A comprehensive review of reactor design for biogas production is presented in the manuscript.

Sản xuất phân hữu cơ từ chất thải biogas để tạo ra nguồn phân bón và giải quyết ô nhiễm môi trường là vấn đề quan trọng hiện nay. Do đó, nghiên cứu được thực hiện với mục đích đánh giá ảnh hưởng của việc phối trộn một số vật liệu ủ đến chất lượng của phân hữu cơ từ chất thải biogas và từ đó xác định được vật liệu phối trộn cho chất lượng phân hữu cơ từ chất thải biogas tốt nhất. Thí nghiệm được tiến hành tại phường Hương Vân, thị xã Hương Trà, tỉnh Thừa Thiên Huế trong thời gian từ tháng 11/2019 đến tháng 3/2020 trên 6 công thức với các vật liệu và tỷ lệ ủ khác nhau. Thí nghiệm gồm có 03 lần nhắc lại, bố trí theo kiểu RCBD. Kết quả nghiên cứu cho thấy vật liệu và tỷ lệ ủ khác nhau có ảnh hưởng đến tính chất lý, hóa học của phân hữu cơ từ chất thải biogas theo thời gian ủ. Trong các vật liệu ủ thì kết hợp rơm rạ, vỏ lạc với dung dịch và chất cặn hầm ủ biogas (1:1) + chế phẩm Trichoderma và rơm rạ, vỏ lạc, than bùn với dung dịch và chất cặn hầm ủ biogas (1:1:2) + chế phẩm Trichoderma cho chất lượng của phân hữu cơ là tốt nhất (N 2,72 - 2,92%; P2O5 0,92%; K2O 2,84 - 4,64%, OM 33,50 - 38,84%). Hiệu quả kinh tế trong sản xuất phân hữu cơ từ chất thải biogas thu được cũng cao nhất ở các công thức này. Cần mở rộng kết quả nghiên cứu trên quy mô lớn hơn và thử nghiệm hiệu quả của nó với cây trồng góp phần tăng năng suất, cải tạo đất và giảm thiểu ô nhiễm môi trường từ nguồn chất thải chăn nuôi này. ABSTRACT Producing organic fertilizer from animal wastes after biogas treatment to create fertilizer source and solve environmental pollution is now an important issue. Therefore, the study was conducted with the purpose of assessing the effect of mixing some composting materials on the quality of organic fertilizer from animal waste after biogas production and thereby identifying good mixing materials with the best organic fertilizer from animal waste after biogas production. The experiment consisted of 6 treatments with different composting materials and rates which was conducted in Huong Van ward, Huong Tra town, Thua Thien Hue province from November 2019 to March 2020. The experiment consisted of 3 replicates which was arranged in the Randomize Complete Block Design (RCBD). The research results showed that different composting materials and rates affected on the physical and chemical properties of organic fertilizer from animal waste after biogas production. Among the composting materials, the combinations of liquid and solid wastes from the biogas digesters with rice straw and peanut husks (1:1) + Trichoderma; rice straw, peanut husks and peat (1:1:2) + Trichoderma gave the best quality of organic fertilizers (N 2.72 - 2.92%; P2O5 0.61 - 0.92%; K2O 2.84 - 4.64%, OM 33.50 - 38.84%). The highest economic efficiencies also obtained in these treatments. It is necessary to expand the research results on a larger scale and to test its effectiveness on crops that contribute to productivity, soil improvement and environmental pollution from the animal wastes.

The article explores the economic essence of the concept of “waste-free technologies” and it was determined that the main idea of waste-free production is the conversion of residues of secondary raw materials and waste obtained in the production process into finished products, which is able to bring economic benefits to the enterprise. Has been analyzed the dynamics of the volume of generated and utilized agricultural waste in Ukraine in 2010-2019. And it was determined that no more than 30% of waste is disposed of, the share of which has been rapidly decreasing in recent years. It was noted that the agro-industrial complex is one of the material-intensive and high-waste sectors of the economy, which accounts for a significant part of greenhouse gas emissions - more than 12%. It is concluded that the introduction of waste-free production technologies in agricultural enterprises of Ukraine will not only reduce the amount of waste generated and their impact on the environment, but it is also a source of income by replenishing the energy balance of enterprises. Attention is paid to the most promising direction for the introduction of waste-free technologies at agricultural enterprises - the production of biogas from organic waste (biomass). It is noted that agricultural waste, mainly animal waste, such as manure, chicken droppings, can be an additional source of replenishing the energy balance of agricultural enterprises and ensuring the energy security of the region. Have been analyzed the volumes of animal waste generation in Ukraine and the potential for biogas production from manure in Ukraine in 2020. A sample of the 10 largest biogas plants in Ukraine was carried out and the further development of the bioenergy sector in 2050 in terms of biogas production was predicted. 6 main environmental effects from the introduction of biogas complexes in Ukraine were identified. The main directions of the European Green Deal are characterized and the key areas of harmonization of domestic legislation on waste management are given with European ones.
