Air Quality<br />

To ensure air quality and people’s health, C.Vale monitors the emission of atmospheric<br />

gases. The cooperative takes advantage of the methane gas (CH4) generated by the<br />

effluents from the starch modifiers factories and Piglet Production Unit to generate<br />

clean energy and minimize the greenhouse effect. In the case of the two cassava<br />

processing industries, in Assis Chateaubriand and Terra Roxa, both in Paraná (PR), the<br />

measure reduces the costs of industries with firewood by approximately 75%, that is,<br />

it avoids the consumption of more than 50,000 trees /year.<br />
