Evaluation of Biodegradable Waste Quality by Drying for exploring the Possibilities of a Potential Renewable Energy Source in Yangon City, Myanmar

Abstract

Biodegradable waste to fuel becomes a potential renewable energy source to gain environmental and economic benefits in the world. To explore the opportunities of a potential renewable energy source from the biodegradable wastes in Yangon city, the study collected 12 different waste samples from the four districts of Yangon and evaluated the composition of the collected wastes. Then, the study assessed their moisture contents by Halogen Moisture Analyzer and dried 23 prepared waste samples (100 grams, 300 grams and 500 grams in mass) by Binder Laboratory Heating and Drying Oven at 105°C. The study also analyzed the effect of moisture reduction in volume reduction, weight reduction and heating value increase of the biodegradable waste samples after drying. The results showed that about 50% of moisture reduction could contribute approximately 25% of volume reduction, 40% of weight reduction and 200% of heating value increase (initially approximately from 3 Mega joules per kilogram to 8 Mega joules per kilogram). Therefore, if drying could be conducted with a renewable source such as solar energy and a waste heat source from industrial sectors, the dried biodegradable wastes could be beneficial in the energy and environment sector of Yangon city. The objective of the study was to estimate the biodegradable waste quality of Yangon city by drying for a future potential renewable energy source.

Development and Performance Evaluation of an Integrated Bio-degradable Kitchen Waste Comminution and Drying Machine

“…If such wastes were to be processed to a stable shelf life (20 % to 40 % moisture content), a reasonable amount of moisture has to be removed. Interestingly, such significant moisture removal causes a substantial reduction in the weight and volume of biodegradable waste but increases the energy value (Tun and Juchelkova, 2018). Although some researchers like Polprasert (2007) and Yang et al (2015) have shown considerable interest in biowaste treatment and its benefits relying on the sketchy overview of a range of treatment options, less emphasis was made on the development of a dedicated treatment technology taken into account bio-waste sources, compositions, and characterization.…”
