Sustainability and replication potential of community-based composting: a case study of Bangladesh
Composting is one of the potential waste reduction strategies of solid waste management. It represents waste not as a problem but as a potential resource in the sustainable development paradigm. A number of community-based composting projects are being piloted in the cities. Some projects are successful to produce lasting impacts; however, many projects could not support themselves or expand ...

The potential of GHG emission savings for programmatic CDM by municipal solid waste composting in the Western Province - Sri Lanka
The Western Province (WP) of Sri Lanka, as the most populated province in the country is burdened with a high level of municipal solid waste generation. Out of the 48 administrative local authorities within the WP, only 16 local authorities are practicing municipal solid waste composting. All other local authorities are practicing the most common method of MSW disposal; open dumping. The study ...

Odour emissions from MSW composting process steps
This study brought to the definition and the calculation of Odour Emission Factors (OEFs), which enable the estimation of odour emissions from a composting plant by relating the quantity of odour emitted to the atmosphere to a given associated activity. The results show that the aerobic biological treatment has the highest odour impact, with an OEF of 1.4 ? 108 ouE t−1. Moreover, the efficiency ...

Composting cotton industry by-products. Evaluation of Use of cotton solid wastes compost as a substrate.
The textile industry at region of Entre Douro e Minho is located at Ave valley and is responsible for a great amount of cotton solid wastes. Currently these wastes, which are characterised by a high C/N ratio and some salinity, are directly applied to soil by farmers without any previous treatment (Zucconi et al, 1981). Extraction of peat causes environmental damage (Smith, 1992) which leads to ...

Fluorescence characteristic changes of dissolved organic matter during municipal solid waste composting
Dissolved organic matter (DOM) of municipal solid waste (MSW) consists of minerals, water, ash and humic substances, and is known to enhance plant growth. In this study, inoculating microbes (ZJ, MS) were used in municipal solid wastes composting, and composting implemented a industrialized technology. During composting, dissolved organic matter was extracted from the compost and purified. The ...

Agricultural Use of Different Residual Waste Composts - Current Situation and Experiences in France
ABSTRACT Quality standards have been recently established in France for sewage sludge composts and other urban composts (greenwaste, biowaste and municipal solid waste composts). These standards allow to guarantee the innocuousness of the composts. Other standards have been defined in order to predict the compost effects on soil properties: the index of biological stability (ISB), based on ...

The relevance of moisture control in organic municipal Solid waste windrow composting process
The valorisation of the Municipal Solid Waste composting fraction assumes importance in management strategies of the MSW and constitutes a way of producing an organic material such as humus to improve the soil aeration, the water holding capacity and valuable product when used as soil amendment because it is a source of nutrients (N, P, K) and useful for recovery of poor and degraded soils. It ...

Effect of urban waste compost application on soil near-saturated hydraulic conductivity
Received for publication February 22, 2008. Compost application tends to increase soil fertility and is likely to modify soil hydrodynamic properties by acting on soil structural porosity. Two composts, a municipal solid waste compost (MSW) and a co-compost of green wastes and sewage sludge (SGW), have been applied every other year for 6 yr to cultivated plots located on a silt loam soil in 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 ...

Suitability of Wastes from Olive-Oil Industry for Initial Reclamation of a Pb/Zn Mine Tailing
An incubation experiment was conducted to evaluate the ameliorating role of two organic amendments—olive-mill solid wastes and compost from olive-mill solid wastes- in the ecological reclamation of a lead/Zn-mine tailing collected in southern Spain. Four enzymatic activities (dehydrogenase, β,-glucosidase, urease and phosphatase) and soluble and AB-DTPA extractable Pb and Zn and were ...

Application of chicken manure organic fertilizer crusher
Chicken manure organic fertilizer crusher is a more important part of chicken manure organic fertilizer production line. It is a machine exclusively for producing organic fertilizer. The appearance of the crusher greatly reduced the crushing of manpower, and the efficiency was greatly improved. Application of organic fertilizer crusher The advent of chicken manure organic fertilizer crusher has ...

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 ...

Perspectives on organic waste recovery relative to composting and anaerobic digestion
Generally speaking, organic waste renders its self suitable for recovery purposes owing to the nutrient elements it contains and the energy stored in the biochemical bonds of its constituent organic compounds. Both composting and anaerobic digestion (AD) have been used since a long time ago in reclaiming organic material. It seems that the first modern composting process was developed in 1920s ...
