The Potential of City Park Waste for Biofuel Feedstock Production: A Case Study in Bandung City, Indonesia

Abstract

The increasing number of city park waste / open spaces will contribute to increase the number of city park waste. This study aims to predict waste generation and analyze city park waste’s potential as biofuels. The observation was conducted on ten thematic parks in Bandung city. The waste generation model was developed based on the number of trees, season, and park area. The average waste generation is 0.44±0.24 tons/day/park. The seasonal changes’ effect in parks had a significant impact with a P-value of 0.02 < 0.05. The most significant variable of the city park’s waste generation is the number of trees in every park with a P-value = 0.0002 < 0.05 generation model = 0.5435(number of tree) - 0.6783. The characteristics of sulfur and moisture are 0.31% and 2.6% respectively, while carbon content is high as much as 40.45%. The heating value is 15.2 MJ/Kg, and fixed carbon is 72%, while the cellulose is 21.87%. The study concluded that the city parks’ waste is potential as raw material for biofuel or transformed into other energy materials.
