Produced The Compost by Recycling The Municipality Waste

Abstract

Around 5000 tons of food waste are prooduced every day in Iraq, accounts for about (50%) of the waste that we get rid of .Waste sent to landfill for disposal may breakdown and produce methane gas that causes greenhouse effect ,as well as odour , epidemics , and disease because of the disintegration. The aims of the research are to produce organic fertilizer through the recycling of domestic refuse. It has been working through this research to collect the domestic food waste which represent the nitrogen source, as well as the remains of cleaning and trimming of various trees and the remains of lawn mowers, and use of sawdust white wood which represent the carbon source. Working on dried and arranged in layers of perforated plastic containers for the purpose of ventilation, it was moisturized with two different types of water and monitored fertilizer maturity for four months. Previously the fresh water was used for the purpose for moisturizing the mixture (tap water) later the domestic wastewater have been used. The comparison was made between the results of tests performed; the test has come up with the resalt that the use of "domestic wastewater" rich in living organisms and bacteria to hydrate the mixture is better than the use of "tap water". The felicitous fertilizer is rich with nutrient nitrogen 2.3%, phosphorus 13% and potassium 20% etc. There are a number of important factors affecting the process of production of fertilizer, including air ventilation, temperature, and moisture content in the mixture, which ranges from 40-60% to provide a suitable medium for microorganisms within the mixture. Where less than 40% lead to dry mixture and kill organisms.
