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.

Solar energy represents one of the future energy sources with a high potential, used as an alternative to conventional methods, especially during summer. The advantages of using solar energy are multiple, this type of energy being virtually endless and free, and its use has no negative effects on the environment, being regarded as a clean energy source. Solar energy has multiple applications in agriculture, one of its benefits being that it is used for dryers as an alternative energy source, especially in regions with a high solar potential. In this paper different types of fruits and vegetable dryers, nationally and abroad are presented, as well as results obtained from different methods of solar dryers.
