Bio-conversion of organic waste using composting technologies – a review
Composting is nowadays evolving as a highly technical process for processing organic waste separately replacing landfilling along with municipal solid waste. Vegetable waste with high organic content can be composted to produce nutrient rich material that can work as soil conditioner instead of dumping in open landfills. Various studies reveal that due to high organic content of vegetable waste ...

Relative efficacy of two methods of vermicomposting for bio-degradation of organic wastes
Two methods of vermicomposting were used for the bio-degradation of organic wastes, viz., the pit method and the heap method. The efficacy of these two methods was compared under field conditions over three seasons (winter, summer and rainy) by using one of the most promising composting worm species, Eisenia fetida. One hundred adult earthworms (Eisenia fetida) were released in each pit and heap. ...

Effects of C/N ratio on mixed organic waste composting in a rotary drum composter
Effects of Carbon to Nitrogen (C/N) ratio on the rotary drum composting of organic waste were examined by measuring changes in various parameters. It was observed that time courses of four C/N ratios: 16, 22, 30 and 38 were different. Initial C/N ratio 22 produced high-quality compost (total nitrogen-2.1%, total phosphorus-4.3 g/kg) within 20 days. While in case of C/N 16, compost yields 1.8% ...

Mixed organic waste composting using rotary drum composter
A combination of vegetable waste, cattle manure and saw dust was utilised for high rate composting in a household rotary drum composter. It was found that temperature remained above 55?C for a period of two days, Faecal Coliforms and Faecal Streptococci decrease from 7.5 ? 108 to 5 ? 102 and 1.5 ? 107 to 5 ? 103 bacteria/g, respectively. Negligible VFAs production indicated full aerobic ...

Introduction of composted digestates in agriculture
Municipal organic waste is increasingly recycled by aerobic composting or anaerobic digestion procedures. In 1997, 230 000 Mg organic waste were composted and used for agriculture in the region of Cologne, which is an increase by 70% compared to 1994 (Anonymous, 1999). Therefore, the effects of compost on the soil and the plants require studies on:- its nutrient contents to contribute to the ...

Home composting of organic waste - part 2: effect of management practices
Home composting (HC) can produce safe compost if properly managed, while reducing municipal disposal costs. This project investigated the sanitary and safety impact of HC management (with/without bulking agent, batch/weekly feeding, with/without regular mixing) using the Plastic (P) and Wood (W) bins, the Rotary Drum (RD) and the Ground Pile (GP) filled with equal wet volumes of food waste (FW) ...

Conversion of solid organic waste into compost using Trichoderma spp. and its application on some selected vegetables
This study was conducted to evaluate the potentiality of Trichoderma species as a bio-conversion agent for composting of solid organic waste and examine the effects of produced composts on the growth of two types of vegetables. The experiments were conducted both in vitro and in vivo processes. In vitro conversion of solid organic waste, the highest height and weight losses were found 42.64 ...

Post-composting techniques of digested household waste
Compost making is a method of recycling whereby organic waste is broken down to organic soil with the help of oxygen demanding microorganisms. There are different ways of making compost. Some require more labour and an exact procedure has to be followed; others neglect the precise procedure, which has advantages and disadvantages. Organic material, including toilet waste, can also be recovered to ...
