Buildings Environmental Impact Assessment

Posted in: Environment by admin on January 1, 1998 | No Comments

To study a construction as an element modifying the environment simulation by infographic photocomposition are made. The physical resources of the landscape can be seen before and after the incorporation of the construction planned (quality of content).The composition of the elements of the construction and the aesthetic resources can be studied by different points of view and modifications can be done throughout the simulation. The visual and aesthetic aspects of any object are defined by their color, form, line and texture characteristics. Elements of compositive reference can also be verified such as the scale and the spatial character in the landscape. The texture are particularly discussed in this article. Simulation are done using computer infographic technology in the composition using the landscape photograph as a background where some elements can be removed or added including constructions designed in CAD (computer aided design). The simulation allows for modification of the elements (changes in the characteristics, in the location) in the landscape.
Interesting work can be done with such tools to verify the impact on the landscape of construction projects. Optimization of location and material characteristics can be done before the construction is started. Lowering the visual impact of the construction on the rural landscape can help lower the attention given to swine buildings.

Odor Control for Animal Agriculture

Posted in: Environment by admin on | No Comments

Odour generation, emissions, and movement are very complicated processes. Several technologies can significantly reduce odours from livestock production but can range in the simplicity, maintenance and price. This document reviews many odour control technologies, some that have been rigorously tested and other that have yet to be evaluated but are generally accepted by some engineers and/or producers.
There is the option of reducing odour during land application. This can be done through injection or immediate incorporation of the manure into the soil. Another aspect of manure application is the agitation of liquid manure storage facilities. Pit additives are the odour control method most often used in these situations. There is the option of reducing odours during the manure storage period as well by adding a cover. There are gas impermeable covers that capture gases, which are then treated, or permeable covers, which simply decrease the amount of emissions into the air. Anaerobic digestion and aeration are also methods of reducing odours during storage.
There are odour reduction practices for buildings as well. The best method appears to be the elimination of the source of odour rather than the treating of it afterwards. This can be done through diet manipulation, keeping the building clean and sprinkling vegetable oils in swine pens. After odours are created, it is possible to reduce them through ventilation in the buildings and by using biofilters.
Odour management plans, part of manure management plans are becoming standard practice. They would list odour sources, odour potential and control strategies. These plans may serve to diffuse some of the controversies between producers and their neighbours by directing the discussion to strategies and practices.

RESEARCH STRATEGY FOR HOG MANURE MANAGEMENT IN CANADA

Posted in: Environment by admin on | No Comments

The hog industry in Canada has grown more than 400% since 1982. The 12.2 million animals in
Canada produce 24.4 million tons of manure annually. The present trend in hog production, i.e., toward
a greater number of animals per farm, results in excessive manure production on a small land base and
greater distances to utilize manure for crop production without causing pollution. This situation has led to environmental concerns with current hog manure management.

Environmental impacts of hog production are

Selecting Suitable Swine Ventilation

Posted in: Energy by admin on | No Comments

It pays to make sure that a ventilation system performs properly and efficiently. Select a fan that meets your needs for reliable performance at a reasonable cost over the life of the product. Fans use the most energy of any component of the ventilation system. The more aerodynamic the fan, the more air it will move per kilowatt of electricity. Match the blade size to the motor size. A fan blade that is too large or too small for the motor will cause it to run hot and will not last as long. Add a cone to the exhaust side of the shroud to spread out airflow. This is more efficient than abruptly slamming the air into a wall of still air outside. Check beltwear four times per year. A worn belt rides lower in the sheaves reducing airflow significantly. Dirty shutters can reduce airflow by 20%. Maintain motors, inlets and bearings by cleaning and yearly lubrication.
