“…The proper quantity of fresh materials was received to shape a windrow pile to be aerated using a machinery turner. Since the available market wastes (fruits and vegetables) did not meet the desired C/N ratio, materials rich in C (plants residues) were added as bulking agents to provide the required C/N ratio necessary for effective decomposition [14]. The mixture was chosen with respect to the needed C/N ratio of 25-30 for the beginning of the composting process [15].…”

“…During the composting, aerobic microorganisms break down the organic materials into stabilized substances through several chemical reactions: mineralization, ammonification, and denitrification, etc. The byproducts of biological process are heat, carbon dioxide, ammonia, and humus-containing products of lower weight and volume [14,30]. The mass and volume reduction during the composting of several raw materials is a key factor in the design and operation of composting facilities.…”

Developing countries face serious environmental, social and economic challenges in managing different types of organic waste. Proper treatment strategies should be adopted by solid waste management systems in order to address these concerns. Among all of the treatment options for organic waste, composting is the most approved method as an effective strategy to divert solid waste from landfills. This experimental research aimed to examine the potential of producing compost from source-separated municipal organic waste in Shiraz, Iran. Market waste (fruits and vegetables) and garden waste (plant residues) were used as the raw input materials. They were subjected to the windrow pile composting method in an open site area. The process was monitored against several physical, chemical and biological parameters. In-situ measurements (temperature and moisture content) were carried out on a daily basis. Sampling and lab analyses were conducted over the period of the biological treatment. The final product was of acceptable moisture and nutrient levels, pH, Electrical Conductivity (EC), and Carbon/Nitrogen ratio. All of the analyzed compost samples had lower concentrations of heavy metals than the Iranian and German standards. Overall, the results obtained revealed that composting is a promising method for municipal organic waste treatment. The findings also imply the effectiveness of the source-separation collection method in the production of high-quality compost.

“…The volume reduction is a result of the organic matter degradation by microbial activity during the composting process has also been pointed out by several investigators [10,32]. Additionally, previous studies investigating the change of physical properties of organic wastes during the composting phase have demonstrated that high levels of biodegradable organic matter increased the capacity of the microorganisms to oxidise the material, and consequently reduced the volume [17,33].…”

This study investigated the effect of microbial inoculant (Emuniv) on composting of biodegradable domestic solid wastes for over 30 days. Three different types of treatments were used for the composting of source separated domestic solid waste. The results showed that the use of microbial inoculant in the composting of domestic solid wastes enhanced the biodegradation of composted organic material, which is evident from the considerable changes in temperature, moisture content and volume reduction with time. The compost treatments with Emuniv inoculant recorded higher temperature for the duration of composting phases, compared to treatment without Emuniv inoculant. Whereas, the moisture content and volume reduction of all treatments was showed a decreasing trend during the composting process. The larger reduction was seen in the treatments with Emuniv inoculant. Additionally, according to the results of analysis of variance (ANOVA), there was a statistically significant difference in temperature, moisture content and volume reduction between treatments. Moreover, the utilisation of microbial inoculant in composting was also can improve the quality of final compost product as reflected by the total nitrogen and available phosphorus contents in the compost product were higher than in the control.
