ethanol production from surplus sugarcane bagasse and trash is compared with conventional first generation ethanol production from sugarcane and with integrated first and second generation; simulations were developed to represent the different technological scenarios‚ which provided data for economic and environmental analysis. Results show that the integrated first and second generation ethanol production process from sugarcane leads to better economic results when compared with the stand-alone plant

Sources of air pollution Air pollution caused by vehicles has been identified as the largest contributor to air pollution in the world. Air pollution caused by vehicles is when the burning of fossil fuels to power our vehicles gives off CO2 emission. This pollution by vehicles also produces toxic substances such as sulfur dioxide and carbon which can be fatal to humans. Air pollution also comes from industry as this source of pollution spews particulate matter and chemicals into the atmosphere
