The Hydrogen Energy Potential of Solid Waste: A Case Study of Misrata City

Abstract

This study presents an overview on solid waste that can be used as a source of bioenergy in Misrata including municipal solid waste (MSW), industrial solid waste (ISW), and healthcare solid waste (HSW) as biomass sources. The management of solid waste and valorization is based on an understanding of MSW's and HSW's composition and physicochemical characteristics. Of MSW's, the results show that organic matter represents 59% of waste, followed by paper-cardboard 12%, miscellaneous 10%, plastic 8%, metals 7% and glass 4%. While HSW comprised of 72% general healthcare waste (non-risk) and 28% hazardous waste. The average general waste composition was: 38% organic, 24% plastics, and 20% paper. The potential of hydrogen energy produced from biogas in Misrata including MSW, and other organic feedstock such as food and kitchen waste, animal wastes, clover and reeds, wheat residues, barley residues, HSW and sewage waste as biomass sources. The total potential hydrogen output is estimated to be around 10,265 tons per year.

Experimental Study of Biogas Production from Cow Dung as an Alternative for Fossil Fuels

“…It is a step by step process where the organic carbon is mainly converted to carbon dioxide and methane. Figure 1 shows the process of producing biogas divided into hydrolysis, acidogenesis, acetogenesis and methanogenesis [4].…”

Experimental Investigation of Biogas Production from Cow Dung in an Anaerobic Batch Digester at Mesophilic Conditions

“…Biogas is a renewable energy source and in many cases exerts a very small carbon footprint [1]. Biogas may be produced by anaerobic digestion with anaerobic organisms, which digest material inside a closed system (air-tight tanks with different configurations) [2]. Biogas is produced as landfill gas (LFG), which is produced by the breakdown of biodegradable waste inside a landfill due to biochemical reactions occurred inside microorganisms.…”
