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 ...

Accumulation and mobility of heavy metals in fenugreek (Trigonella foenum-graceum L.) and tomato (Lycopersicum esculentum Mill.) grown in the field amended with urban wastes, and their composts and vermicomposts
Accumulation of cadmium (Cd), lead (Pb), zinc (Zn), copper (Cu) and manganese (Mn) in roots, stems and leaves of fenugreek and tomato grown on lateritic soil amended with municipal solid waste, market and floral waste, and their composts and vermicomposts prepared using three earthworm species, were assessed. The heavy metal accumulation in the plant parts showed significant correlations with ...

Microbial characterisation of vermicompost and compost of urban waste processed by three earthworm species - Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
Species diversity of bacteria, fungi and actinomyctes of vermicompost and compost of the organic fraction of municipal solid waste, vegetable market waste and flower waste were assessed using pour plate technique. Of the total 91 entities, 62 were bacteria and 29 were actinomycetes in MW, followed by that of MSW and FW, with 59 and 55 bacterial; 25 and 22 actinomycetes entities, respectively. The ...

Co–composting as a management strategy to reuse the white–rot fungus Trametes versicolor after its use in a biotechnological process
White–rot fungi are extensively used in biotechnological processes but little is known about the disposal of fungal biomass after its use. Final products stability parameters (self–heating test and respiration index) indicate that co–composting of the white–rot fungus Trametes versicolor with Organic Fraction of Municipal Solid Wastes (OFMSW) ensure a higher stable final ...

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 ...

The control of the process and compost quality
The European Commission has adopted a new proposal on landfill whose objective it is to reduce the impact of waste disposal on the environment. The new directive introduces a series of new elements and provides for a number of safeguards with respect to both existing and new landfills. Disposal of waste is the option of last resort in the hierarchy of waste management principles; the Commission ...

Remediation of heavy metals from urban waste by vermicomposting using earthworms: Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus
This study revealed that three earthworm species, viz., Eudrilus eugeniae, Eisenia fetida and Perionyx excavatus, through vermicomposting remediated heavy metals - Pb, Zn, Cd, Cu and Mn from the urban waste - organic fraction of Municipal Solid Waste [M(O)SW], vegetable Market Waste (MW) and Floral Waste (FW). The concentrations of Zn, Cd and Cu were 36.1, 50.9 and 70.2% higher in M(O)SW compared ...

Quality of compost: the experience of veneto region
The Regional Administration of Veneto Region (Italy) established in 1991 the rules for authorisation of composting plants for treatment of pre-selected organic wastes, including urban sludges, organic fraction of municipal solid wastes and animal manure. Also chemical composition of compost were regulated (Table 1). Some composting plants started working in 1994; at the moment seven farms are ...

Organic Fertilizers Production Process (original article in Bahasa Indonesia)
Illustrated description of complete production lines of granulated organic fertilizers. Raw materials can be either farm waste, animal husbandry waste, biomass, and biodegradables of municipal solid waste. The product is granulated fertilizers with specifications in comformity with the Indonesian National Standard (SNI) and those being enforced by the Indonesian Ministry of Agriculture. A number ...

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 ...

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 ...

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 ...

Composting in flanders: the vlaco experience
In Belgium, waste policy mainly belongs to the responsibility of the regional authorities. Therefore, apart from some European regulations, Flanders, Wallonia and Brussels have their own laws, rules and strategies with respect to waste management. These different situations are inevitably related to the political, socio-economic and natural conditions of these regions. In execution of the Waste ...

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) ...

Composting Process and Organic Fertilizers Production
Illustrated explanation of two broad stages that are usually applied in most composting facility. First, composting process that convert raw compost into mature compost. Second, organic fertilizers production that convert mature compost into granulated fertilizers. Feedstock for composting stage can be farm and animal husbandry wastes, biomass from plants, and biodegradables that have been ...

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 ...

Review of current European practice of MBT compost-like output use and application to land in relation to environmental protection
Mechanical-Biological Treatment (MBT) is often a key element in National Strategies for the diversion of Biodegradable Municipal Waste (BMW) from landfill. Unlike incineration, it provides flexibility in the system, which is important in those Member States where the system will have to undergo widespread changes in the amount and quality of residual waste that is dealt with. The main objectives ...

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 ...
