Composition of Domestic Solid Waste on Biogas Production and Characteristic in MSW Landfill

Organic solid waste will undergo a decomposition process and produces some gases compounds such as a large enough of Methane (CH4), Carbon Dioxide (CO2) with Oxygen (O2) and N2. The high heating value of CH4 in biogas can make biogas as a good source of renewable energy and environmentally friendly. Biogas calorie efficiency is proportional to the concentration of CH4 in biogas. However, the quantity and quality of biogas that produced in landfill depend on the characteristic and density of domestic solid waste in landfill. The composition of organic and inorganic waste and the density of waste pile will alter the CH4 content. This study focuses on measuring CH4 content of the solid waste with different density while also identifying the composition of disposed solid waste. The result indicates that the CH4 content ranges from 33% to 57.7% with 22.19% to 42.24% of CO2 and approximately 1.21% - 7.92% of O2. The presence of inorganic waste and density level of waste contribute to the decomposition rate and CH4 content.

Suitable Environment

Solid waste which is sent to Jatibarang landfill in Semarang City can reach up to 4000 m3/day. The composition of solid waste consists of 61.95% of organic waste and 38.05% of inorganic waste. The environmental impacts of solid waste can be reduced using bioreactor methods which being able to accelerate the solid waste decomposition. Large amount of solid waste which is sent to Jatibarang landfill certainly has great potential to environment pollution. Therefore, a technology such as landfill bioreactor is needed to speed up the decomposition process of organic solid waste. Landfill bioreactors are characterized using a range of technologies in order to create an suitable environment for degradation processes. In this study four bioreactors simulated landfills that consist of hybrid bioreactors and anaerobic control bioreactors. The result shows that hybrid bioreactor has increases the decomposition process of organic solid waste. The hybrid bioreactor also produce more methane in subsequent anaerobes.

Waste is a source of problems, if not managed properly it will cause environmental pollution, especially in residential settlements that live around landfills in Puuwatu District. The purpose of this community service activity is to reduce the pile of waste in the Puuwatu sub-district landfill through the application of the principle of zero waste, namely by processing organic solid waste into compost, leachate into a decomposer microorganism solution, and recycling inorganic waste for verticulture media. Activities undertaken to achieve the objectives of the Community Partnership Program (PKM) are through mass and group counseling to partners, training and plot demonstrations. Through these activities, partners who live around the landfill had been able to process organic solid waste, with the hope that the volume at the landfill will decrease, and the partner's income will increase. Partners who were actively involved in the activity had been able to produce compost (labeled Komsa-Mitra) that was ready to be commercialized, and are also able to process leachate as a source of decomposer microorganisms (labeled mollin) in the composting process. Partners around the Puuwatu landfill were also able to utilize waste plastic and rubber containers into a vegetable cultivation container with a verticulture system in the yard and the hervested vegetable was used to meet the family's nutritional needs.

Windrow Composting

Out of the millions of tons of Municipal Solid Waste (MSW) generated annually in India, only about 75-80% of the waste gets collected and out of this, only 22- 28% is processed and treated, and the remaining is deposited indiscriminately at dump yards. Hyderabad city generates around 5500MT of waste every day. And only 20% of the waste is used for composting using the windrow composting process. MSW composting is a rapidly growing method of solid waste management in Hyderabad and In-Vessel composting is the recent initiative by the Govt. of India to reduce the organic solid waste generated at the source. The present study was aimed to assess the degree of accumulation and contamination of the heavy metals in composts from Centralised Windrow Composter (CWC) and Source Segregated Accelerated Vessel Composter (AVC). Compost Samples from CWC and AVC were analysed for metals concentration using Energy Dispersive X-ray Fluorescence Spectrometers (ED-XRF). CWC samples were found with slightly high concentrations of heavy metals like Zinc (0.51 – 0.66%), Copper (0.36 – 0.45%), Nickel 0.03 – 0.05%), Iron (11.46 – 13.27%), and chromium (0.06 – 0.14%) compared to AVC. AVC samples contained high concentrations of Calcium (14.99 – 64.19%), Potassium (9.13 – 29.59%) and Phosphorous (1.55 – 3.43%) when compared to CWC. The current study does a comparative analysis on the process and nutrients available to assess the quality of the compost from both sources. Considering the above findings source segregated AVC seems to be a better composter than centralised CWC, as the concentrations of Ca, K, and P required by the plant were abundant in AVC. Also, considering the process aspect, there is always scope for cross-contamination if the waste is separated after treatment which is the case in CWC.

Solid waste management is now one of the big challenging issues in Bangladesh. With increasing population, volume of solid waste is increasing enormously. Production of biogas from organic solid waste is an environment friendly energy source as well as great management strategy of solid waste. The purpose of this current study is to determine the physicochemical composition of solid waste to determine the prospect of biogas production. Results reveal that, temperature and pH of the solid waste should be controlled for the maximum production of biogas. On the other hand, collected solid waste samples contained sufficient amount of moisture for the production of biogas. Appropriate temperature controlling system and buffer for pH maintenance can play a great role to maximize biogas production.J. Environ. Sci. & Natural Resources, 9(2): 151-154 2016

Humification Degree

Abstract Background: Microbe is the driver for disposing of organic solid waste (OSW) during aerobic fermentation. Notwithstanding, the significance of microbe is always underestimated in numerous preceding studies about the aerobic fermentation products assessment. Results: Here, we investigate the humification degree (HD) and humic acid content could be assessed in terms of the bacterial community. Microbial sequencing and bioinformatics approaches are combined to analyze the biological characteristics of 105 aerobic fermentation samples collected. The bacterial communities could make predictions, which even correctly determines the categories of OSWs with 94% accuracy. Furthermore, the bacterial genera screened are designated as the bacterial code, which is substituted into the Random forest model to predict HD. And the bacteria codes can also provide a better prediction of the HD. Conclusions: Our result suggested that bacteria codes a reliable biological method is proposed to assess HD effectively. Our experiment not only proves that the aerobic fermentation can be revealed by biological means. The bacterial codes can also be used as an ecological and biological indicator to evaluate the quality of the aerobic fermentation of different materials. This study further provides new insights on the use of microbe to evaluate the content of various substances during the degradation process of OSWs.
