Design in Keeping with international air quality standards.

The ALUTRINT Aluminium Complex will be fitted with modern gaseous emission treatment systems which have been designed to ensure that the gaseous byproducts of the aluminium smelter, rod mill and wire and cable processes meet or exceed local and international standards for ambient air quality.
The gaseous emissions arise out of the conversion of alumina into molten aluminium metal and the transformation of this molten metal into aluminum wire and aluminium cable.
All of the emissions generated from the various processes in the ALUTRINT plant will be captured by a high vacuum system which pulls all of the emissions into ducting and then routes them to a gas treatment center where more than 98% of the pollutants are scrubbed out of the vacuumed air using alumina.
This alumina, on which is absorbed all of the pollutants, is sent back into the process to produce molten aluminum metal thus creating a closed cycle of pollution treatment and control that is protective of human health and the environment.
A very small quantity (less than 2%) of the pollutants generated from the various processes, may escape to the atmosphere from stacks on the gas treatment units, the roofs of the pot rooms and stacks on the rod mill plant. In order to make sure that these very low emissions are not posing a risk to human health or the environment, ALUTRINT conducted an ambient air quality modeling study to determine what happens to the vented gases when they leave the various points of emission.
This type of study is used to predict what the concentration of contaminants would be in air at ground level (i.e. the air we breathe) and how far away from the point at which they are emitted they would have an effect on people and the environment. The study is done using mathematical formulae that mimic how nature behaves and also how climate conditions would be when there is no wind, very warm, and with a temperature inversion present.
Thus all air quality models are run under parameters which best represent the worst possible atmospheric
conditions and produce results that will only be seen in La Brea and its environs 3% of the time per year.
The results of the study conducted for the ALUTRINT Complex prove that air emissions from the aluminium smelter plant are confined to within the boundaries of the ALUTRINT property under the worst possible climate conditions i.e. when there is no wind to dilute and disperse the emissions, when the air is warm and humid and when there is a temperature inversion acting like a blanket preventing any emissions from dispersing vertically into the air column
