Influence of temperature during the initial phase of Composting on biological activity and emission of Ammonia and dinitrogen oxide
Composting is a robust and cheap biological treatment method useful for all solid biodegradable waste. The performance of composting can vary substantially depending on managing conditions such as oxygen supply and compost temperature. Oxygen and temperature affects the rate of degradation and may also influence emission of NH3 and N2O. The gaseous N losses during composting from organic ...

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 ...

Stability measurement of Biosolids Compost by Aerobic Respirometry
Oxygen uptake of biosolids compost was measured during both laboratory and full-scale studies. Aerobic respirometry of solid samples of compost provided a precise measure of microbial activity. There was a noticeable decreasing trend in oxygen consumption over 25 days of composting, thereby indicating increasing stability. Moisture content also was found to affect the compost stability. During ...

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 ...

Composting in the Subarctic – Design
Our Ideal Design The Actium Batch Compost Drum has become an essential tool for Fort Albany First Nation’s community garden. This article details why Fort Albany First Nation needed a composter and why the design of the Actium Batch Compost Drum suited our needs. Why was a composter needed in a remote subarctic community? Fort Albany First Nation (also known as Peetabeck) is a remote and ...

Composting in the Subarctic – Operations
The Actium compost drums are used in a variety of climates. In the tropical and subtropical climates, the composter is used year-round. In temperate climates, the Actium Batch Compost Drum can be used year-round because the drum is insulated. However, the decaying process can be slowed where winter temperatures are below freezing for a prolonged period. There are two approaches to maintain hot ...

Composting of vegetable waste in subtropical climates
This experiment examined the possibility of using composting as a method of waste disposal in subtropical countries, such as the United Arab Emirates (UAE), where temperatures are high and humidity is low. In order to simulate conditions in the UAE, a representative mixture of wastes generated in the UAE was prepared and tested at ambient temperatures resembling those of subtropical countries. ...

The wonder of red wiggler worms
Worms are going to play an ever-increasing role in waste management and soil production. Red wiggler worms convert food scraps and paper into nature's finest fertilizer. As nature's original recyclers, they consume approximately half their weight daily!Many municipalities have introduced organic collection programs, and backyard composting is widespread. Vermicomposting is a great alternative for ...

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; ...

Advantages of compost turning and fermentation of chicken manure
1. Start fermentation quickly. Generally in summer, the composting time for chicken manure compost treated by a professional compost turning machine to reach the harmless index is about 20 days, and it usually takes about 60 days for natural fermentation to reach this index. Mainly because of the growth and reproduction of microorganisms, the materials in the materials are fermented and degraded, ...

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 ...

Mariposa compost facility odor remediation update
Staring in the winter of 2006 the staff at the Mariposa Compost Facility worked quickly to make process changes to bring odor issues under control. Here is the latest chapter in their story. Odor (incident) Logs In January 2007 the Local Environmental Agency (LEA) provided "odor logs" to the county residents that were troubled by the compost facility's odors. The odor logs were collected ...

Basic process of manure fertilizer production from farm manure
The composting method of organic manure production is a process of mineral, humic and harmless degradation of organic matter in solid manure by microorganism under the condition of artificial control of water, carbon nitrogen ratio and ventilation. Composting is mainly divided into aerobic composting and anaerobic composting, which is mainly aerobic composting at present. Composting manure ...

Project Compo-Ball - Case Study
Compo-Ball is developing a new system for monitoring the temperature and humidity during composting processes. The 3-year research project is funded by the European Commission and brings together 16 partners from 9 European countries. The aim is to bring affordable wireless composting-sensors to the European composting ...

Canadian Food Inspection Agency (Cfia)Manitoba Composting Exercise
Overview: Nordevco was invited to participate in a Canadian Food Inspection Agency (CFIA) composting exercise by the CFIA Manitoba Team. The purpose of Nordevco’s participation was to evaluate the impact of BactiDomus Technology on the composting process specifically related to achieving and maintaining temperatures appropriate for the inactivation of the pathogen responsible for avian ...

Composting in the Subarctic – Moisture
Regulating Compost Moisture during Hot Composting Hot composting is most effective at decomposing organic waste when moisture levels are approximately 50%. A compost with excessive moisture will cause Low temperatures that are below 40°C (104°F); smells foul; and/or brown liquid to be visible or easily freed when squeezing compost. Excessive moisture while composting does not ...

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) ...

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 ...

Modeling composting kinetics: A review of approaches
Composting kinetics modeling is necessary to design and operate composting facilities that comply with strict market demands and tight environmental legislation. Current composting kinetics modeling can be characterized as inductive, i.e. the data are the starting point of the modeling process and determine the type of model used. It is argued that the inductive empirical approach has been ...
