“…A standard family produces up to 0.5 -0.75 kgs of kitchen waste per day. [22]. Environmental dilapidation under the present circumstances has further fortified due to the incessant production of CO 2 and organic acids produced during microbial metabolism of vermin composting that eventually decrease the pH during the process.…”

With the rapid urbanization managing of the kitchen waste generated by the large population has become a big problem. Kitchen wastes comprises of vegetables peels, fruit peels, smashed fibre of fruits, spare uneaten food items, food grains etc. These are loaded with nutrients and organic material, and can be easily recycled. In recent years, researchers have explored the various methods of extraction of biogases like Hydrogen, Methane, etc. from these biodegradable wastes. This paper reviews the various research works carried out on the synthesis of kitchen waste using anaerobic digestion process, biomethanation or composting. Hydrogen, a valuable gas is produced through the anaerobic fermentation of domestic organic waste in the absence of pretreatment or photo-fermentation, or bioaugmentation of indigenous fermentative communities. Chronological dark and photo fermentation process is also an emerging way studied for production of bio-hydrogen using kitchen waste. Esterification and hydrolysis process has also been utilized to synthesize kitchen waste forming Lactic acid. Thermo-chemical Hydrolysis of Kitchen Waste through optimization of temperature, time and chemical compositions, Fourier Transform Infrared Spectroscopy, microaeration process are studied resulting in bio-fuel production. Methane formation combining Kitchen Waste and black water using two-stage upflow anaerobic sludge blanket (UASB) septic tanks at the lower temperatures has also been studied and it appears to be more efficient than using only Black Water. Organic acids produced from anaerobic digestion of kitchen waste using an integrated method consisting of freezing, thawing, centrifugation, filtration and evaporation. Thus this review paper deals with the study of various methodologies of kitchen waste utilization.

“…The percentage of nitrogen, N content in the compost fluctuates as shown in Figure 7. Increase in N content may be due to the mineralization and active microbial cellulolytic degradation of complicated molecules in which releases N and other ions into the compost [37]. Volatilization of ammonia, on the other hand causes nitrogen loss as it is released into the air as ammonia gas [36].…”

Composting is a biochemical process in a controlled aerobic environment where thermophilic microorganisms stabilize organic waste substrates into valuable humus-like products. Three parameters which are known to affect the composting process including temperature, aeration rate and composting time. This research aims at developing a model to describe the relative influence of different temperatures, aeration rates and reaction time on the composting process and how it affects the final quality of EFB compost produced. EFB samples were mixed with urea as a source of nitrogen and fresh compost as inoculum. The composting process was carried out in a composting test bench for a total of 42 days. The moisture content was found to be significantly affected by temperature and reaction time. Carbon loss was significantly affected by all three factors. Nitrogen content was affected by aeration rate, reaction time as well as interaction between temperature and reaction time. Changes in total ions over time showed a positive correlation with the value of conductivity (Pearson correlation coefficient of 0.853) and the largest reduction in C/N ratio (from 30.2:1 to 17.6:1) was obtained at temperature of 40°C and aeration rate of 0.4 L/min kg. The results of this study could form a basis for palm oil mills to improve the quality of EFB composts produced within a short maturation period and with low C/N ratio.

“…Different bulking agents have been used at waste sludge composting operational tests. Many researchers have reported the effectualness of adding bulking agents such as lignocellulosic waste (Fels et al, 2016a), date palm (Fels et al, 2016b), recyclable plastic (Zhou et al, 2014), palm oil (Tweib et al, 2014), tree bark, sawdust, peat (Zuokaitė and Zigmontienė, 2013), straw (Kulikowska and Klimiuk, 2011;Bousselhaj et al, 2004;Cartney, 2004;Gouxue et al, 2001), wood chips (Eftoda and Mc Cartney, 2004), waste paper (Tang and Katayama, 2005), grass (Kulikowska and Klimiuk, 2011) and compost in improving the composting process.…”

<div> Sludge is the ultimate by product of all traditional and conventional wastewater treatment processes. Conversion of the treatment sludge into new products is a significant disposal alternative for these wastes. In this study, branches, leaves and the organic and inorganic trash coming out from the aerated sand trap unit have all been mixed up with determined mixing ratios and composting has been realised by windrow-composting technique. The present study was conducted to investigate the effects of 4 different treatment sludge composts and chemical fertilizer on soil characteristics and plant (oat and grass) yields. Experiments were conducted in randomized black design with 3 replications in a plastic high-tunnel greenhouse. The sludge composts of sample1 (S1) and sample2 (S2) were applied at rates of 4 t/da and 6 t/da. Chemical fertilizer was applied in the form of N8P6. Grass was sown in a rate of 20 gr m-2. Oat was sown in pots at a rate of 60 seeds per pot and then thinned to have 40 plants in each pot. Sludge composts in grass and oat culture significantly improved soil characteristics and increased the plant yields. It was concluded that sludge composts could be used as an alternative soil amendment. </div>
