Energy sustainability is keyed to social development, and thus finding renewable and clean energy sources is crucial to modern society. Waste to energy technology is of particular interest in recent years because the feedstock supply is relatively stable and the technology is less influenced by climate and geographic conditions. This study first reviews this technology, and then provides a case study to explore the potential investment, economic benefits, and environmental consequences associated with such an application. The results indicate that the energy conversion efficiency and net social benefits are highly dependent on the composition of the wastes, the transportation costs, and the distribution of regional population. The results imply that for the application of waste to energy technology to be efficient and effective, the locations of refuse plants play an important role, as well as the recycled rates of municipal solid wastes. Policy implications regarding these points are also discussed in detail.

In recent years, the environmental and rechargeable Li-ion battery has become a hot spot in new energy technology field. The performance of Li-ion battery is in a large part affected by the advanced special equipment. The current and voltage needle is an important part in the special equipment. Based on the existing current and voltage needle, the paper designs a new current and voltage needle which is used for Li-ion battery formation. In this paper, we make a detailed analysis of mechanical structure and point out the superiority compared with the existing current and voltage needle. Cooperating with other formation equipment, it has achieved good economic benefits for the enterprise.

Abstract Distributed energy technology is an important developing direction of the future energy technology. This paper puts forward a distributed energy system named SOFC–GT–RC (solid oxide fuel cell–gas turbine–recovering carbon dioxide) with liquefied natural gas (LNG) as fuel and recovering carbon dioxide. In the system, the cold energy of LNG can not only cool the compressor inlet air to reduce the consumption of compressor work, but also to supply cold energy and to recover CO2. Based on the mathematical model of each part, the thermodynamic calculation model of the whole system is built by fortran, which is embedded in aspen plus. The results of calculation indicate the thermal efficiency and total power efficiency are 74.5% and 56.7% while the exergy efficiency is 61.8%. In addition, some operating parameters such as fuel utilization factor and fuel flow rate are selected. Based on these operating parameters, the new system thermodynamic performance is studied. The results point that this SOFC–GT–RC system fueled by LNG increases the total power and decreases waste of cold energy and the pollution of the environment, which would be an effective utilization style of energy in China's LNG satellite stations.

Distributed energy technology is an important developing direction of the future energy technology. This paper puts forward a distributed energy system named SOFC-GT-RC with LNG as fuel and recovering carbon dioxide. In the system, the cold energy of LNG can not only cool the compressor inlet air to reduce consumption of compressor work, but also to supply cold energy and to get zero-CO2 and other emissions. Based on mathematical model of each part, the thermodynamic calculation model of the whole system is built by FORTRAN, which is embedded in ASPEN PLUS. The results of calculation indicate the thermal efficiency and total power efficiency are 74.5% and 56.7% while the exergy efficiency is 61.8%.

Nowadays, waste-to-energy has become a type of renewable energy utilization that can provide environmental and economic benefits in the world. In this paper, we evaluated the quality of twelve biodegradable waste samples from Myanmar by binder laboratory heating and drying oven at 105 °C. The calculation methods of the Intergovernmental Panel on Climate Change (IPCC) and Institute for Global Environmental Strategies (IGES) were used for the greenhouse gas emission estimation from waste disposal at the open dumpsites, anaerobic digestion, and waste transportation in the current situation of Myanmar. Greenhouse gas (GHG) emission and fossil fuel consumption of the improved biodegrade waste utilization system were estimated and both were found to be reduced. As a result, volume and weight of the biodegradable wastes with 100% moisture reduction were estimated at approximately 5 million cubic meters per year and 2600 kilotonnes per year, respectively, in 2021. The total GHG emissions in the current situation amounted to approximately 1500 and 1800 Gigagrams of CO2-eq per year in 2019 and 2021, respectively, while the total GHG emission avoidance from a sustainable approach amounted to 3500 and 4000 Gigagrams of CO2-eq per year, respectively. The study aimed at highlighting the utilization of biodegradable wastes as a clean energy source in developing countries.
