“…An increase in EC usually takes place during composting as a result of the release of salts due to the mineralization of organic material. The range of variation of this parameter is dependent on the nature of the initial feedstocks: increases from about 600 to 800 µS cm -1 during composting of sheep manure and straw, [14] from 1166 to 2230 µS cm -1 during composting of sewage sludges mixed with wood shavings, [15] from 900 to 1600 µS cm -1 during composting of pig manure and sawdust, and from about 2000 to 3000 µS cm -1 during composting of food waste [16] were reported. In contrast, Li et al [17] observed a decrease from 4360 to 2750 µS cm -1 during composting of a mixture of sewage sludges, pig manure, and sawdust.…”

This study reports a pilot experiment of composting of anaerobically digested sewage sludges deriving from the production of biogas in a wastewater treatment plant. Two composting piles (about 15 m 3 each) were prepared by mixing 50% and 30% sludges with lignocellulosic material. The composting process was monitored through determination of the main physico-chemical properties. The maturity of the composts was assessed by determination of the respiration index and dehydrogenase activity. The data indicated that, at both sludges concentrations, the process produced a final compost suitable for agricultural applications. The germination and growth indexes of Lepidium sativum indicated the lack of phytotoxicity of the final materials. The suitability of the final product as a field improver and horticultural substrate has been attested through bioassays conducted on maize and chrysanthemum.

“…These parameters are within the range required for agricultural use as soil amendment agreed as [24][25][26][27]. The data above showed significant indicator that the product of food waste compost gain from this study is not at an optimum level compare to use of standard compost as fertilizer which is 23: 1 (Kim et al, 2008) [14]. in Sample (%)…”

“…Moreover, several studies also laid out the effect of adding bulking agents in which to adjust the MC, N-content, C/N ratio, and void spaces between particles in the past, since most waste materials such as sewage sludge, food waste and animal manure have too low C/N ratios and too high MC for efficient composting [6][7][8][9]. Generally, modification of physical properties of composting feed-stock may resulted from different bulking agents as well as change the biodegradation kinetics and composting performance [7,8,10].…”

“…Generally, modification of physical properties of composting feed-stock may resulted from different bulking agents as well as change the biodegradation kinetics and composting performance [7,8,10]. Thus, it is a prerequisite for collection program managers to have detail information about the nature and quantity of solid waste generated in order to set appropriate management systems which in this paper will be focused on composting.…”

High food waste generation in Malaysia that reached up to 15, 000 tonnes per day assign for major problems towards environment, economy and social aspect. Alternative method had been studied for the past years, but composting was seen among the best possible solution to treat this matter. Composting not only has an environmentally method but it also produces a valuable end product that will benefit in agricultural sector. Further studies had been done in this paper to represent their macro and micro nutrient quality as well as their bioavailability towards plant and the analysis of data collected in both CHNS analyser and mathematical method using ultimate analysis. This study also applied enhanced composting process with its segregation, drying, grinding and standard aeration time. Each container has been rotated for 5 minutes yet different resting time was applied which are 25, 55, 155 minutes namely A, B, C and D within 2 hours period. Result shown that overall Carbon (C), Nitrogen (N) and Sulphur (S) concentration increases as the higher aeration was applied while the Hydrogen vice versa. The highest elemental percentage distribution recorded is carbon (31%) while the lowest recorded is S (0.115%). The data collected from Ultimate Analysis was seen not applicable to be use as it has the same content as food waste after composting. The compound molecular formula recorded was C29H7N5S. Regarding ratio of carbon to nitrogen results, it was found that it ranged from 5.39 to 5.71% for different compost treatment under study, where the lowest value of C and N ratio (5.39%) for sample C and the highest value (5.71%) was obtained for sample B with all has the same C/N ratio which is 6: 1 which suitable range in application of soil amendment. Therefore, this study found a significant relationship between chemical factors and compost formation which contribute to better analysis, especially to food waste management.

“…In Taiwan, approximately 16.5 million tonnes of food waste is produced annually [20]. In the Republic of Korea, more than 22% of the municipal solid waste is reported to be food waste and the generation rate of food waste was 0.24 kg d −1 in 2004 [21]. This is equivalent to 4.3 million tonnes of food waste annually.…”

Food waste is a global problem. Each year food worth billions of dollars is wasted by the developed economies of the world. When food is wasted, the problem does not end at that point. More than 95% of the food waste ends at landfill sites, where converted into methane, carbon dioxide and other greenhouse gasses by anaerobic digestion. The impact of food waste to climate change is catastrophic. Food waste problem tends to increase in next 25 years due to economic and population growth mainly in Asian countries. In addition, when food wastes buried at landfill sites their energy content is lost. Although food waste is a huge problem, its global size and extent has recently become a hot topic in the academic community. This paper summarises the size of the global food waste problem together with the estimation of the amount of energy lost when food wastes dumped at landfill sites. Calculations in this study also revealed that energy lost at landfill sites equals to 43% of the delivered energy used for the preparation of foods in the US, 37% of the hydroelectric power generation of Japan, and more than 100% of the current annual renewable energy demand of UK industries.
