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 ...

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 ...

Evaluating the potential of an electronic nose for detecting the onset of anaerobic conditions during composting
Most bad odours in composting plants are formed under anaerobic conditions and often they could be avoided if detected early enough. In this project an electronic nose was used to evaluate the odours produced during a composting process at bench scale. The electronic nose consists of an array of electronic chemical sensors with partial specificity and an appropriate pattern recognition system ...

Corrosive free compost facility for Waste Options Nantucket
Veldeman’s daughter company, Universal Fabric Structures was appointed by Nantucket Waste Options to construct their aeration and biofilter structures. More then 5.500m² of TFS structures in a custom layout meet the island wind loads and provide a corrosive free environment while solving waste disposal on the island. The biofilter will store the compost and odor control media for 2-3 years ...

Pilot project cuts odor, cost for humanure compost
Utah Valley Daily Herald Article on the benifits on using micro-pore membrane compost covers when composting highly odorus material. In February of 2009 Utah Valley's North Sewer Distirict conducted a pilot study to determine the effectivness of mirco-pore membrane compost covers in reducing odors from biosolids (sewage sludge) composting. Odor testing was conducted over a term of one month ...

Odor issues at Mariposa MSW composting facility
The Mariposa County MSW composting facility was built at the county landfill to remove some dry recyclables from the waste stream and to produce compost for daily cover. One key motivation was to increase the lifespan of the landfill and to postpone a costly long-haul. The facility was permitted, designed and built by a team of engineers and vendors. It began operation in the summer of 2006. ECS ...

A Guide to Compost Sheep Manure for Organic Fertilizer
Sheep manure contains protein, organic acid, cellulose, aliphatics and so on, and its organic matter content is higher other livestock manure. Without fermentation, sheep manure has various harmful bacteria that cannot be directly used on plants growing, or there would bring germs and parasite spreading. What’s worse, without proper disposal, sheep manure would generate heat to consume oxygen in ...

Greenwood Mushroom Farm Composting - Case Study
Envron co-operated with the Canadian Mushroom Growers Association, the Canadian Federal Government, Provincial Government and Greenwood Mushroom Farm on a full-scale mushroom bunker composting odor control project at Greenwood Mushroom farm. This work was based on earlier work conducted with the British Columbia Ministry of Agriculture that showed positive odor control with Ozone and mushroom ...

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 ...

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 ...

The CAMBI process and agriculture, a sustainable solution?
Abstract Both public acceptance and interest from farmers for spreading biosolids from waste water treatment plants (wwpt) on arable land, are dependent on some fundamental criteria. These criteria are, however, quite straightforward. The biosolids should be safe, easy to handle, a well documented source of plant nutrition, without disagreeable odours and easily available. A big part of the ...

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 ...

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 ...
