Polycyclic Aromatic Hydrocarbons (PAHs) are a group of over 100 different chemicals that are known to be formed typically during incomplete combustion of organic matter at high temperature. Their major sources in the atmosphere include industrial processes, vehicle exhausts, waste incinerations, and domestic heating emissions. Due to their carcinogenic/mutagenic effects, 16 PAHs are currently listed as priority air pollutants.

Renewable energy plants are expanding and developing at a significant rate in North America and throughout the world. In the United States, the Clean Air Act for reformulated gasoline (RFG) mandates a 2wt.% oxygen requirement, driving the demand for more production. Ethanol is the most viable additive because it is a clean-burning fuel produced from renewable, domestic biomass sources. However, the production of these fuels can result in unacceptable levels of volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxides (NOx), particulate matter (PM) and hazardous air pollutants (HAPs), all regulated by environmental agencies.

Applied to domestic refrigeration, Bioconservacion’s technology increases the shelf-life of fruit and vegetables, providing benefits to equipment manufacturers and consumers. As they mature, fruit and vegetables naturally produce ethylene. Ethylene accelerates maturation which is why systems that eliminate ethylene, VOCs and fungus spores from the environment are especially beneficial, as they lengthen the useful life of fruit and vegetables increasing shelf life by up to 25%.

CFC usage in industry
Although the use of CFCs in domestic products has been widely phased out, CFCs chemicals still prove a vital ingredient in the production of insecticides and herbicides. Such products aim to increase the rate of crop production all over the world. All aspects of such a manufacturing process in relation to environmental impact must be well controlled. The use and pre-emission removal of CFCs in the intermediary steps of the insecticide production needs to be monitored with 100% efficiency.
