Anaerobic Digestion Process of Food Waste for Biogas Production: A Simulation Approach

et al. 2019

View full text Add to dashboard Cite

Anaerobic digestion (AD) involves a series of biological processes in which organic material is broken down and transformed into biogas. A simulation model of the AD process in treating food waste to produce biogas was developed using Aspen Plus software. The components list, thermodynamic property package, reaction list, reactor model, and process condition were specified in Aspen Plus. Sensitivity analysis was performed to study the effect of hydraulic retention time and changes in food waste composition on the biogas production. The methane composition in biogas decreased when the hydraulic retention time was increased which is due to the reduction of substrate consumption during the AD process. The process model is able to represent the AD process and provides a good approximation on the production of biogas under various process operating conditions.

“…Refering to Indonesia standard for emission of Thermal Power Generator, the predicted emission of NOx and SOx in this study were lower as compared to threshold value (NOx= 50 ppm and SOx=170 ppm). On the contrary, dioxin emission somehow higher (dioxin emission standard according to US Federal Emission Limit is 0.02 ppm) [7]. The presence high amount of water (70 -80%) in MSW enhances digestion of organic compound in MSW especialy in preliminary stage of anaerobic process.…”

Abstract. Municipal solid waste (MSW) in MedanCity is facing problems either with the quantity and management of MSW. Local authority only dumped approximately 73.9% MSW in the landfill over the years. Spontaneous phenomena of methane formation in dumping site indicates the potency of MSW conversion into energy by biochemical conversion. On the contrary, the presence of plastics, woods, papers, etc. in the MSW show the potency of MSW to be treated by thermal conversion. Both thermal incineration and anaerobic digestion may convert MSW Medan City into energy. This study evaluates potency of MSW conversion into renewable energy using proximate and ultimate analysis. Overall, MSW of Medan City has the opportunities to be converted into energy by both thermal and biochemical conversion with a special requirement such as pre-dry the MSW prior incineration process and degrade organic MSW in a bioreactor.

“…Further, there are many types of solid waste, which can be generally classified into three. The first is any materials that can be recycled or accumulated, which can be useful objects but no longer wanted such as scrap metal, glass, cans, paper, plastics, wood and similar materials [2]. The second type is the ones which can be segregated for disposal or burned for energy recovery, reclaimed and accumulated speculatively.…”

This study simulated the routes of a municipal solid waste collection by a mathematical model of Dijkstra's Algorithm. Its aim was to achieve route optimization by shortening the distance travelled by the municipal solid waste collectors. The waste collectors usually face difficulties in selecting the most cost-efficient routes to collect wastes due to the presence of multiple collection points. It is observed that unsystematic collection route planner travelled by the waste collectors increases the time and cost of waste management. Thus, to reduce the time and cost of collection, it was hypothesized that the routes taken by the waste collectors be shortened to optimize the cost-effectiveness. This study again hypothesized that employing a mathematical model of Dijkstra's Algorithm would be able to demonstrate the route optimization.
