Content: The reduction happens because recycling reduces the need to burn fossil fuels such as gasoline, diesel and coal. Recycling also lowers emissions from incinerators and slows the felling of trees -- and living trees can soak up carbon dioxide. The Downside
There are cases where recycling may influence air quality for the worse. In Houston in 2013, for example, the city found that metal recycling operations released smoke into the surrounding neighborhood, including cancer-causing chemicals. Welding and cutting the metal releases metal compounds into the air, something environmental regulators hadn't previously considered. The effects of the metallic pollution could potentially include higher cancer rates in the surrounding area. The city said it would work with recyclers to reduce the city's exposure to the chemicals.
