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 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 ...

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 ...

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 ...

Tulare Farms - Case Study
Tulare Lake Compost (TLC) is a state-of-the-art 175 acre composting facility located near Kettleman City in Kings County, California. At the facility, an eco-friendly process is used to combine agricultural and green waste from the Central Valley with biosolids from Los Angeles County to create an optimal mixture for composting. TLC employs the covered aerated static pile (ASP) composting ...

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: Art and science of organic waste conversion to a valuable soil resource
Raw organic materials such as grass clippings and manure are transformed into stable soil-like humic compounds through decomposition in the composting process. Composting is an age-old practice found in various settings, ranging from domestic to industrial. Compost maker machine is becoming an increasingly practical method of organic waste disposal when landfills reach capacity ...

Effect of covering composting piles with mature compost on ammonia emission and microbial community structure of composting process
Received for publication February 14, 2008. To control ammonia (NH3) volatilization from the dairy cattle (Bos taurus) manure composting process, a compost pile was covered with mature compost and the gas emissions evaluated using the dynamic chamber system. The peak of NH3 volatilization observed immediately after piling up of the compost was reduced from 196 to 62 mg/m3 by covering the compost ...

Evaluation of FTIR spectroscopy as a maturity index for herbicide-contaminated composts
This paper analyses the use of Fourier Transform Infrared (FTIR) spectroscopy as a maturity index for herbicide-contaminated green wastes composts. Four in-vessel composting systems were set-up with Compost A constituting of uncontaminated grass clippings and Composts B, C and D contaminated with atrazine, 2,4-D and tordon 101 respectively. The physicochemical properties of the composts were ...

How long does it take for organic fertilizer fermentation equipment to process compost
According to different raw materials, organic composting fermentation equipment can be divided into high temperature composting and ordinary composting. High temperature composting takes plant materials with high fiber content as the main raw materials, and generates a lot of heat through composting and fermentation under aerated conditions. The temperature of composting is very high (50-60 ...

Cow manure organic fertilizer production line process
The cow manure organic fertilizer production line is a complete set of equipment for processing organic fertilizers with cow dung as raw material. The cow manure organic fertilizer manufacturing process uses crops such as straw and rice bran as fillers, and then sprinkle the biological strains through the turner. It is turned over once every 1-2 days. It can be completely decomposed in 7-10 days ...

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; ...
