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 ...

LCA case study on lawn establishment and maintenance with various peat and compost contents in substrates
The environmental impacts of the establishment and maintenance of lawn, including the production and use of various substrates, were analyzed by life cycle assessment (LCA). The project focused on comparing substrates with different peat and compost contents using pilot substrates and developed a calculation tool to optimize landscaping from an ecological perspective. The impact categories ...

A cost-effective method for controlling compost air emissions
In October 2007, ECS began conducting trials at California State University Fresno (CSUF) to explore using the new patent pending AC Composter (ACC) covered aerated static pile system to manage dairy manure solids and comply with airquality standards. A two-zone portable pilot system was delivered by ECS and installed at the CSUF research dairy. This research is being conducted under a Phase I ...

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 ...

Composting Food Waste & Emissions Collection, Anchorage, Alaska - Case Study
For better moisture and odor control, this composter has duct work exhausting air out of the vessel through the discharge end of the composter. If need be, the exhausted air / duct work could be direct to a biofilter. ...

Reduction of ammonia emissions during composting by Uncoupling of oxygen demand and heat removal
Intensive pig production systems result in high emissions of ammonia, odour and greenhouse-gases (methane and laughing gas) by exhaust ventilation air. Moreover, large amounts of manure (faeces and urine) are produced with insufficient nearby land for applications (Imbeath, 1998). These outputs lead to environmental problems related to acidification and euthrofication of natural ecosystems, ...

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 ...

Odour pollution problems caused by composting activities in flanders: current situation and abatement strategies
In Flanders, garden fruit and vegetable (GFV) waste is selectively collected and composted in 7 composting plants, in six of which aerobic indoor composting is used. In the seventh plant waste is anaerobically digested first followed by an aerobic post-treatment. The total amount of waste composted was about 275 000 tons in 1997 (OVAM, 1999). The nominal capacity of the composting plants varies ...

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 ...

Hybrid composting systems: appropriate technology for Austral-Asia?
Composting is a strongly emerging option in waste management in Austral-asia. It has been widely acknowledged that a successful integrated waste management strategy must adequately address the organic waste stream. Composting is the most economical, efficient and ecologically sustainable option to deal with organic waste if properly managed and economically and socially integrated into a ...

Formation and emissions of ammonia and greenhouse gases from stored and composted solid animal manure
Beside other branches of industry, agriculture is an important source of methane (CH4) and nitrous oxide (N2O) emissions and the most important source of ammonia (NH3). In spite of several investigations concerning ammonia and greenhouse gas emissions during storage and composting of liquid and solid animal manure, the real extent of these emissions is still unknown. This is mainly because of the ...

Why Biochar Production Instead of Composting Biomass
In the pursuit of sustainable biomass management, two distinctive approaches have garnered attention: biochar production and composting. Both methods seek to convert organic matter into valuable resources, but they differ significantly in their mechanisms and outcomes. This article delves into the world of biochar production and composting, exploring the advantages of choosing biochar production ...
