Organic Solid Wastes

Present work deals with the exhaustive investigations of rapid de-lignification processes from source-sorted organic fractions that are recalcitrant in nature. Organic solid wastes (OSW) belong to the organic fraction of municipal solid wastes (MSW) and they act as enormous potential substrate for alternative source of energy in the form of bio-fuels. Nevertheless, these substrates are not easily biodegradable and the degree of biodegradability is solely dependent on the composition and characteristic of organic solid wastes in municipal solid wastes. The component responsible for recalcitrance of organic solid wastes is lignin that occurs in variable amounts in different plant residues. In order to remove the recalcitrance from organic fraction municipal solid wastes and to make it more easily degradable by microbial groups, certain pretreatment techniques have been adopted and they are applied either individually or in combined way for enhancement of anaerobic digestion (AD) process. The present work studied the effect of acid treatment with acetic acid on the used substrate, evaluated its effectiveness on biogas production, and studied the concentrations of CH4 and CO2 during the fermentation period, which amounted to 90 days. All results are presented in clear curves for the purpose of facilitating the study.

Organic Solid Wastes

Tehran anaerobic digestion power plant has been built on the eastern margin of the urban district by the purpose of processing the organic fraction of municipal solid waste. One of the most suitable methods for the treatment of organic matter is the use of anaerobic digestion (AD) process, which in addition to significant reduction of organic solid wastes, will produce valuable energy. Contributing to maintain the environment, improve urban health, saving on fossil fuels and producing rich fertilizer for agricultural use are important advantages of anaerobic digestion. The plant has been set up in 2014 with a nominal acceptance capacity of 300 tons of organic solid wastes per day and the nominal power generation of 2000 kWe. This system has been faced with considerable challenges in terms of quantity and quality of biogas during operation. The high concentration of hydrogen sulfide (H2S) in produced biogas and the lack of appropriate technologies in the plant for biogas refining are critical for the biogas generator engine deployed in the complex. The purpose of this article is to investigate the factors affecting the quality and quantity of Tehran's AD plant biogas using various H2S reduction approaches and selection of appropriate implementing technologies. The results showed that the recirculation of the digester slurry increased the methane content by more than 30% and reduced H2S by more than 98%.©2020. CBIORE-IJRED. All rights reserved

Organic Solid Wastes

Rapid growth of population in Kathmandu valley has increased solid wastes generation tremendously. One of the best ways of managing the organic wastes is to recycle domestic wastes at the site of its origin by vermicomposting into valuable organic fertilizers. A laboratory experiment was carried out at for proper management of solid wastes of Kathmandu valley, generated from Ayurveda industry, sugar mill (bagasse), wood mill, kitchen, and vegetable and fruit markets. The experiment dealt with the decomposition of solid wastes through the action of red worm (Eisenia foetida). The vermicomposting of mixtures were carried out for 12 weeks. Observations showed that vermicompost obtained from Ayurveda industry wastes was found to be rich in N, P, K and organic matter, and vermicompost from sugarcane bagasse was found best for rapid multiplication of Eisenia foetida. Fish scales and sawdust were identified as worst substrate for this worm.
