Evaluation of a Treatment Method to Control Hydrogen Sulphide Emission from Swine Manure
The oil industry developed a treatment approach that was modified to be used for the swine industry. This approach involves nitrate or molybdate to control swine manures’ emission of hydrogen sulphide. Previous research was on closed systems where the levels...
Use of Nanoparticles to Control Gaseous Emissions from Swine Manure Slurry
Nanoparticles have unique properties due to nanoscale dimension and are highly reactive powder materials. Nanotechnology may allow odour and gas emission control from swine operations. Impact on ammonia, carbon dioxide, hydrogen sulphide and gas mixture from swine slurry by commercially...
Benchmarking Energy Costs in Swine Barns
Energy intensive tasks are involved in swine production. As prices for energy increase along with greenhouse gas concerns, reducing energy use is crucial to reduce cost. Benchmark information was gathered to conduct energy audits documenting energy use in order to...
Application of a Biological Treatment Approach to Control Gaseous Emissions from Swine Operations
High levels of gases including hydrogen sulphide may be exposed to swine barn workers during in-barn manure handling tasks which may be dangerous to their health. Oilfields developed a biological treatment that may be able to adapt to the swine...
Large Group Auto-Sort: Potential and Problems
Large Group Auto Sort (LGAS) applies electronic technology to manage grow-finish pigs and is relatively new. It can be cost effective to assemble many animals into a pen by using similar weights derived from electronic sorting scales and sorting gates....
Belt Conveyor Manure Separation System: Impact on Odour and Gas Emissions
Handling large volumes of manure from livestock operations led to environmental concerns, so innovative strategies are being explored to manage manure in an environmental and economical manner. A tilted belt conveyor (BC) was examined to replace the slatted portion of...
Impact of Drinking Water Sulphate Levels on Gas Emissions and Manure Nutrients
A major environmental concern for the swine industry are odour and gaseous emissions. Sulphur containing compounds are some of the most odourous components of swine. Drinking water quality on air emissions and swine manure nutrients were assessed. Up to 1,800...
Greenhouse Gas Emissions from Covered or Uncovered Earthen Manure Storage
Average season and annual emissions were calculated for different earthen manure storage technology. Nitrous oxide and surface emissions were negligible. As ambient temperature increased, so did emissions as promotion of more biological activity occured. Straw-covered systems reduced carbon dioxide and...
Reducing H2S Exposure Through a Water Spray Method and Monitoring
Hydrogen sulphide is a dangerous gas that is commonly found in swine operations. Reducing the amount of this gas is of great interest in order to keep the workers and animals safe. Hydrogen sulphide is water soluble so theoretically, spraying...
Manure Scraper System Reduces Hydrogen Sulphide Levels in Swine Barns
Manure management tasks such as pulling pit-drain plugs put workers at risk of hydrogen sulphide exposure. In order to reduce the production of hydrogen sulphide, an in-barn manure handling system that provides more frequent and complete removal of manure from...
Measuring Ammonia Emissions from Urine Puddles
Ammonia is a common gas found in pig barns that has a strong odour and can irritate the workers exposed and have environmental consequences. The main sources of ammonia in pig housing units are the urine puddles and slurry pit....
Greenhouse Gas Emission from NAP-Covered Earthen Manure Storage Basin
The agriculture sector contributes to Canada’s greenhouse gas emissions, with livestock operations and manure storage having a large part. A negative air pressure (NAP) cover may help reduce greenhouse gas emissions from earthen storage basins. The NAP-cover had a minor...
