“…The process is maintained in the thermophilic temperature range, the values recorded for C/N are among the values allowed by Solid Waste Management (SWM) rules 16 , in addition, they are consistent with results obtained in other studies, evidencing that the loss of nitrogen in ammonium form during composting, indicating that mature compost was obtained with a high nitrogen content as nutrient and a high fertilizing value 17,18,19 .…”

The purpose of this research was to evaluate the production of compost, biol and biogas from organic solid waste using cattle manure as inoculum through aerobic and anaerobic biodigestion; two prototypes of biodigester were designed on a pilot scale. The monitored variables were pH and moisture in order to obtain good quality compost. Solid organic waste from a sample of restaurants in the city of Cartagena de Indias was used; cattle manure was also used for its production. The growth of mesophilic bacteria, fecal coliforms and fungi present in different stages of composting was monitored, using Brilla Broth and Mac Conkey and Brilla agar. The Most Probable Number method was used for counting microorganisms, and the successful collection of biological by-products and biogas was performed. The obtaining and quality of the compost from the experiments depended substantially on the use of inoculum, as evidenced by the aerobic/anaerobic experiments with inoculum, from which a greater quantity of by-products was obtained and complied with the optimum ranges for the chemical, physical and microbiological parameters for organic fertilizers.

“…Community composting has also gained some attention and has been encouraged by national legislations in recent years, which will be thoroughly reviewed and discussed in the following sections. Meanwhile, home composting presents some potential environmental benefits such as the avoidance of collection, transportation and management of biowaste [42][43][44]. However, home composting also brings some environmental concerns: generation of GHG emissions and odor due to the absence of gas treatment systems [45,46], insufficient elimination of pathogens due to the lack of adequate heating [47] and uncontrolled leachate [48].…”

Decentralized Community Composting: Past, Present and Future Aspects of Italy

et al. 2020

Italy is among the top biowaste-generating countries in Europe, and has a well-structured waste management framework with quite a number of centralized composting facilities. In recent years, there has also been huge interest from local communities in decentralized composting. Although decentralized community composting is common in some countries, there is still a lack of information on the operative environment together with its potential logistical, environmental, economic, and social impacts. Considering the national Italian legislation on community composting as well as successfully implemented projects at EU level, Italy can set a model especially for Mediterranean countries that intend to build decentralized composting programs. Therefore, in the context of this review paper, a brief overview of the composting process was presented together with main applications in centralized and especially in decentralized composting, while the main focus was kept on the operative and legislative information gathered from Italian community composting. There is a huge difference in the number of composting plants between the regions, and the lack of centralized facilities in the central and southern regions can be supported by decentralized solutions. Decentralizing waste treatment facilities and thus creating local solutions to urban waste management strategies will help to achieve the resource recovery and valorization targets in line with the circular economy.

“…For vermicomposting, an increase in total nitrogen content may also be attributed to earthworm activity such as the addition of mucus, growth-stimulating hormones, nitrogenous excretory substances, and microbe-mediated transformations [41]. A reduction in moisture content especially for T, M, and V systems is indicative of the progress in composting [42], which may be attributed to a high consumption rate of cattle manure by microorganisms, earthworms, and bacteria, which makes it friable [43]. The decrease in the amount of carbon may be attributed to its role as an energy source for both earthworms and microorganisms [44].…”

Comparative Performance of Organic Fertilizers in Maize (Zea mays L.) Growth, Yield, and Economic Results

et al. 2020

Maize is a major crop grown and consumed in Uganda and it requires a high fertilizer input. However, the existing inorganic fertilizers in the market are often not affordable especially to small scale farmers, which results in decreased maize yields in the country. On the other hand, there is an abundance of unutilized animal manure, which, when treated, can be used to increase maize yields. This study evaluated the response of maize to products of different cattle manure treatment methods as well as inorganic fertilizer. The treatments such as cattle manure stored under shade (T), cattle manure stored in the open (M), cattle manure slurry digestate (S), vermicompost (V), and an inorganic fertilizer, DAP (D) were all applied in completely randomized block plots at an equal application rate of 50 kg N ha−1 with four replications per treatment. Control plots (C) where no fertilizer was applied were also considered. The experiment was done for two planting seasons in 2018. Number of leaves, plant height, cob, and grain yields were used to evaluate the performance of different fertilizer treatments. Economic assessment of all the six treatments was also carried out to determine the economic viability of applying these fertilizers on maize. Maize growth parameters and yields were all significantly increased (p < 0.05) with an application of both organic and inorganic fertilizers when compared with the control. However, there was no significant difference (p > 0.05) in the maize yields under the different fertilizer treatments. Vermicomposting was the most economically viable manure treatment method due to low operating costs and higher returns on investment that are supplemented with the production of chicken fodder (earthworm biomass) and, thus, can be recommended to farmers for production of a fertilizer that increases maize yields with assurance of economic returns.
