A study on Air Filled Porosity evolution in sludge composting
Air Filled Porosity (AFP) is a key parameter in the composting process, conditioning oxygen availability and heat accumulation. Air pycnometry is considered the most adequate methodology for AFP determination. This technique requires withdrawing a sample of material from the composting mass for AFP measurement, which may alter its physical characteristics. A novel strategy that permits to measure ...

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; ...

Leaf composting in cold climates: a theoretical and an experimental evaluation
There are many factors influencing the process of composting organic waste. This paper provides an experimental and theoretical evaluation of the leaf composting process to elucidate the importance of these various factors during composting of leaves. The analysis is performed specifically for the environmental conditions encountered in cold climates. Theoretical models are developed to evaluate ...

A comparative study between composting and vermicomposting for recycling food wastes
The main objective of the present work was to evaluate the potential of the epigeic earthworms Eisenia fetida and Eudrilus eugenaie regarding the decomposition of food wastes. The effectiveness of composting and vermicomposting for the treatment of food wastes was judged by analysing a wide range of physic–chemical parameters. The results from the compost process monitoring showed porosity rise ...

Growing Media compost - fact sheet 9 - use of composted material in growing media for professional growers
Untitled Document Composted material boosts sustainable growing media Composted material can be a major cost-effective component of growing media being not only a sustainable, well-structured substrate but also a source of nutrients and buffering capacity. What is composted material? In the United Kingdom, composted material is made by composting ...

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 ...

Composting of washed Ulva reticulata seaweed: process parameter variations and compost quality
Co–composting process of unwashed (Run A) and washed (Run B) seaweed Ulva reticulata with bagasse and broiler litter was studied. Peak temperatures of 48.9°C and 55.2°C were recorded for Runs A and B, respectively. For Run A, the starting wet bulk density was 43.31 kgm–3 and increased by 5.2 times on day 23. Net biodegradable Volatile Solid (VS) reductions were 2.19 and 11.44% for Runs A and B, ...

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 ...

The effects of bioadditive in the form of yeasts and zeolite on the composting process and odour emission
The objectives of this paper are to determine the effectiveness of bioadditive in the form of yeasts and zeolite in reducing odour and ammonia emissions during composting and to assess its effects on the process. Two series of experiments were conducted. The higher dosage treatments reached thermophilic temperatures sooner and the high temperatures stayed longer. The application of bioadditive at ...

Microbial biomass c and ninhydrin-reactive n as Parameters to characterize composting process
The use of compost in agriculture is increasing as a source of organic matter to counteract the decrease of organic matter level in soils and as a means of disposal of agricultural and domestic waste. Despite many researches on the subject, there is still the need to improve our knowledge on the compost process and on the methods to evaluate compost maturity. The composting of organic waste has ...

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 ...
