“…Recent research has shown that the growth of aerobic microorganism and fermentation of organic substances accelerates the composting process, and reduces composting time (Velan et al 2005). Moreover, the in-vessel composting system has advantages over the windrow system because it requires less space and provides better control than windrows; it involves high process efficiency (Cekmecelioglu et al 2005). Thus, food wastes have been successfully composted for those purposes (Chang et al 2006).…”

This study aimed to determine the initial air pressure influence on the in-vessel composting for the biodegradable fraction of municipal solid waste in Morocco. For this purpose, representative composting mixture was prepared in which C/N ratio was 26 and moisture content was 70 %. The in-vessel bioreactor was designed and used specially to evaluate the initial air pressure effect on composting process in this study. Thus, daily changes of internal air pressure and temperature were monitored, and physicochemical properties of different composts obtained were also analyzed and compared. Experimental results showed a significant increase in internal pressure corresponding to the initial air pressure of 0.6 bar and a slight increase for the other initial air pressures. The initial air pressure which equal to 0.6 bar allowed maximum value of temperature and final composting product with good physicochemical properties as well as higher organic matter degradation and higher gas production. Composts obtained from experiments under 0.4 and 0.8 bar showed good maturity levels and may also be used for agricultural applications.

“…The windrow system requires a large heap to achieve the thermophilic stage. This fact is supported by Cekmecelioglu et al (2005) who performed a composting process using about 11-m long, 2.5-m wide and 1.2-m high heap using conventional layering and mixing methods. Elsewhere, Sellami et al (2008) have developed cone-shaped heap of 2-m high with a 3-m wide base for co-composting of exhausted olive cake, poultry manure and sesame bark.…”

“…As kitchen waste is produced everyday and everywhere from processed and unprocessed food for human consumption, its composition is quite variable. An optimised kitchen waste formulation and composition involving the use of bulking materials, waste load size and presence of microbes are important in ensuring the commencement of an effective composting process (Fang et al 2001;Ishii and Takii 2003;Cekmecelioglu et al 2005;Stabnikova et al 2005;Cayuela et al 2006;Chang and Hsu 2008).…”

“…Recognised bulking agents used for composting include sawdust (Sundberg and Jönsson 2005;Kalamdhad et al 2008), rice hulls and chips of tree cuttings (Chikae et al 2006), horticultural waste compost (Stabnikova et al 2005) and mulch hay and wood shavings (Cekmecelioglu et al 2005). Newspaper contains 9% of moisture content (MC) (Wayman et al 1992) and 94% of volatile solids with lignin content of the volatile solids ranging from 16% to 22% (Sun and Cheng 2002), while the onion peels contain about 54% of volatile solids (Lubberding et al 1988) with 1.5% dry weight of lignin (Suutarinen et al 2003).…”

Background: To prevent the interruption of the carbon cycle by the disposal of waste to landfills, organic kitchen waste requires proper treatment such as composting to reduce its uncontrolled degradation on disposal sites and subsequent greenhouse gases, odour emissions and nutrient losses. This study investigated the effects of bulking agent, newspaper and onion peels, composting waste load sizes of 2 and 6 kg, or the use of starter culture on kitchen-waste composting consisting of nitrogen-riched substrates, vegetable scraps and fish processing waste in an in-vessel system. The optimised formulation of kitchen waste mixture was used for a 30-day composting study, where the temperature profiles were recorded and the carbon-to-nitrogen ratios were measured as an indication of compost maturity. The kitchen-waste composting process was conducted in parallel in two fabricated kitchen waste composters.

“…Selection of composting methods can be considered in respect to factors such as capital and operating costs, land availability, operational complexity and potential of nuisance problems. Although more expensive compared to other methods, in-vessel composing is more controlled, needs smaller spaces and resulted in less bothers than other techniques (Cekmecelioglu et al 2005). In-vessel composting technique allows the highest degree of temperature control.…”

Purpose Huge amount of yard waste is produced in cities with excessive agricultural activities like Cameron Highlands, Malaysia where most of the time the yard waste is being managed poorly and big portion of it ends in dump sites. Therefore, this study aims to evaluate the applicability of converting yard waste generated in Cameron Highlands Malaysia into high-quality and fast compost via in-vessel method. Methods In-vessel composting technique was applied for speedy biotransformation of yard waste. Addition of food waste, effective microorganisms (EM) and Shimamoto Enzyme Ò (SE) were investigated for improvement of compost quality. Four compositions of feedstock with different yard waste (YW) and food waste (FW) ratios were tested. The compositions were 70%YW ? 30%FW, 80%YW ? 20%FW, 90%YW ? 10%FW and 100%YW. Physicochemical properties of compost including pH, moisture content and C/N ratio were monitored throughout the experiment. Furthermore, quality of compost and its potential for direct application after production were evaluated based on germination index (GI) and nutrient content (NPK). Results The compost samples had pH ranging from 7 to 9 and moisture content of 15.45-32.13%. Initial C/N ratio of all feedstock was decreased throughout the composting process by more than 50%. Seed germination test showed that only 70%YW ? 30%FW feedstock produced immature compost with GI \ 80%. The highest GI of 130% was obtained when FW represented in 10% of the feedstock with addition of EM. Average concentrations of nitrogen, phosphorus and potassium were 1.73, 1.21 and 1.66% in case of EM additive and 1.47, 0.56 and 1.74% in case of SE additive. Conclusion Application of in-vessel composting can improve solid waste management in Cameron Highlands, Malaysia and yield a high-demand product. The approach used in this study can be a good practice for the societies have difficulties in managing their yard waste.
