THE INVESTIGATION OF THE CONVERT TO BIOGAS AND SUBSTANCE SOLUBLE IN WATER OF MUNICIPAL ORGANIC SOLID WASTE COMPONENTS (MARKET WASTES)
Abstract
Biogas is a part of the natural circle. Biogas is formed by the activity of anaerobic bacteria. In nature biogas is produced for example in bogs. It is also possible to produce from biological material in an environment free from air. The gas that is produced is methane (CH4), which is an excellent fuel for heat, electricity, and cars that doesn’t drain the earth’s fossil resources. The raw-material in biogas production has traditionally been waste from the food industries, and communal sewage treatment works. Biogas is comprised of about 60 \% methane, 40 \% carbon dioxide, and between 0.2 to 0.4 \% hydrogen sulfide. One cubic meter clean biogas is approximately the same as one litre gasoline. Biogas is the most environmentally friendly automotive fuel commercially available today In this study, Aqueous slurries of municipal solid organic waste components (market wastes) which has been taken from the Selcuklu Municipality Local Bazaar has been used in experiments in order to determine water solubility and biogas production. The aqueous sludge directly without any pretreatment is carried out to determine the percentage of water solubility of solid in laboratory. The percentages of water solubility of solid sample was determined gravimetrically by filtering and weighting the dry solid. The filtrates were used for anaerobic processes in order to determine the biogas amount. Anaerobic process was carried out at 303 K for 45 days. The volume of produced gas, which was collected at five-day intervals, was measured and calculated at STP (Standard temperature and pressure). It was found from the results that the maximum water solubility, total amount of biogas and methane and the maximum methane content of biogas were 47,35\% (by mass), 63,2 mL, 34,0 mL and 53,79 \% respectively. It was concluded that the market waste is used for biogas production efficiently after converting into water soluble substances.
