Summary
Oman generates a large amount of fruit and vegetable waste every day. An estimated 10 tons of fruit and vegetable trash are organic waste with a high moisture content that decomposes quickly if left open or disposed of in a landfill. Releases fruit and vegetable trash. Open mining emits pollutants and greenhouse gases (GHGs) into the environment. Polluting gases endanger human health, whereas greenhouse gases contribute significantly to global warming. The lack of industrial landfills for this type of trash causes significant environmental, health, safety, and economic problems, necessitating immediate intervention.
Anaerobic digestion (AD) is the process by which a consortium of microbes naturally degrades complex organic matter or organic components of matter (commonly referred to as fermentation) in the absence of oxygen. The most important end products of AD are biogas and digestate (the liquid, dry, or solid residue left after digestion). Biogas consists of methane (40–75%), carbon dioxide (19–38%), and water (6%). Digestate or residual sludge often has a low C.O.D. Pathogens are commonly used as soil fertilizers during composting or landfilling. In addition, leftover organic matter and nutrients can be recovered by incineration or treatment in later processes (Christensen, 2011). fruit and vegetable trash Homes, restaurants, marketplaces, and other commercial sources are good for AD because of their high moisture content (up to 90%), organic matter concentration (80–97%), and biodegradability (Lay et al., 1999). Zhang et al. (2007); Neves et al. (2009). A.D. by fruit and vegetable trash. thus contributes not only to significant waste reduction but also to the recovery of biogas, a source of greenhouse gases. Biogas, a renewable source of methane gas (37.8 MJ/m3), can be used to heat homes or generate power in cogeneration plants. In this study, we present the conditions (temperature, O.L.R.) for the most efficient conversion of fruit and vegetable trash. Convert to biogas and compare the performance of batch and continuous digesters at greater load rates. The findings of this study can be used to set up a centralized digestive treatment plant to handle fruit and vegetable trash. produced in our homes, marketplaces, and other commercial sources. Ultimately, the “circular economy” model will be adopted in waste stream management, which will call for the application of the “reduce, reuse, and recycle” philosophy for all recyclable waste, which contributes to achieving one of the goals of Oman Vision 2040.
Objectives
1- To carry out characterization and Bio-methane Potential test of the F.V.W.
2- To reduce the F.V.W. volume and C.O.D. to an acceptable limit by the A.D. process.
3- To capture and assess the quantity and quality of Biogas for use as a renewable energy source.
4- To establish the optimum temperature and bioclimatic conditions that will favour biogas production from the F.V.W. composition obtained in our environment all year round using batch and semi-continuous digesters.
5- To obtain a digestate quality that could be used as organic fertilizer or soil conditioner and design a “circular economy” model in treating and recovering energy for the organic portion.
