Composting Articles
Organic materials have been composted since there was organic matter to compost. It is nothing new. However, it still can be challenging to compost properly. That is, to produce something that is safe and useful as a soil amendment. This is what we were trying to achieve when we designed the Actium Compost Drums. They can accomplish this relatively easily. with a minimum amount of labour. ...

A statistical approach to evaluate compost genotoxicity
Parallel experiments were carried out to evaluate the induction of genotoxic effects in Vicia faba seedlings treated both with aqueous and organic extracts (dimethyl sulphoxide 5%) of 13 composts, or grown on soil samples to which different doses of the same composts were added. Pearsons linear correlation coefficient and multiple regression were used to study how these two different ...

Disposal of seaweed wakame (Undaria pinnatifida) in composting process by marine bacterium Halomonas sp. AW4
A novel marine bacterium, identified as Halomonas sp. AW4 by partial 16S rDNA analysis, was isolated from the seaweeds in Awaji Island, Japan. Strain AW4 grew well even in the wide NaCl concentration ranges of 0?3 mol/L, where it showed an optimal growth in the presence of 0.5 mol/L NaCl. The organic components were reduced to 73.6% of initial dry weight after 168 h of composting by inoculation ...

Effect of composting on sludge contaminated with heavy metals from three different tannery streams and their bioavailability to plants
This research was conducted to study the influence of composting on tannery sludge contaminated by Cr, Cd, Zn, Cu, and Ni. Composting of sludge streams was performed in three different piles for 60 days. The results showed that the total concentration of heavy metals was increased with composting, except in the TT-3 sample where the concentrations of Cd, Cu, and Ni did not increase. The ...

Pathogen destruction and solids decomposition in composting latrines: study of fundamental mechanisms and user operation in rural Panama
The relationship between temperature, high pH, desiccation, decomposition, pathogen destruction, and user operation in active double vault urine diverting (DVUD) composting latrines located in the Bocas del Toro region of Panama was assessed. Latrine samples were analyzed for temperature, pH, % moisture, carbon-to-nitrogen (C/N) ratio, and presence of specific pathogens. Surveys and visual ...

Compost based products: history, recent activities, chances
The amount of compost originating from source separated organic household waste collection in Germany is still increasing. At the end of the year 1997, app. 3.0 to 3.5 millions Mg fresh matter of non-mature and mature compost were produced in 515 composting plants with an input of respectively more than 1.000 Mg organic waste per year in Germany. According to Mellen (1998) an estimated 27% of the ...

Deregulation and voluntary self-regulation of producers of compost and secondary raw-material fertilizers -against the background of the biowaste and fertilizer ordinances
Since the RAL (Institute for quality assurance and labelling) introduced the quality mark for compost in 1992, more than 300 German composting plants have decided to adopt this voluntary quality control system. This system has significantly helped to define characteristics of high-quality, marketable composts. The quality standards agreed upon with the end-user are guaranteed and monitored within ...

Vermicomposting influences phosphorus microbiology leading to phosphorus enrichment in end product
The investigation reveals the relative efficacy of composting techniques regarding phosphorus transformation of rice straw (RS) and water-hyacinth (WH). The recipe for each substrate: cow-dung:soil:FYM was in the ratio of 6:3:0.5:0.5. Vermicomposting of WH resulted in the highest proliferation of phosphate solubilising microorganisms (PSM) and their solubilising capacity (PSC) besides causing the ...

Effect of different forced aeration methods on Vertical temperature distribution and reaction rates During composting
The application of forced aeration, namely in the upflow (blowing) or downflow (suction) mode has been increasing in modern composting processes. These aeration modes often create a sharp temperature gradient in the composting mass. Examples of widely varying temperatures at different layers of controlled and non-controlled aerated piles have been reported frequently (Fernandes et al., 1994; ...
