What Aluminum Extraction Really Does to the Environment ...

 · Compared to producing aluminum from raw bauxite, recycling old aluminum consumes just 5% of the energy and releases a mere 5% of the greenhouse gases . Infinitely recyclable, aluminum loses none of its integrity even when it is melted down repeatedly, plus, the whole recycling process can be achieved in less than 60 days flat.

What is Oil Shale? | Union of Concerned Scientists

 · Environmental impacts of oil shale. Oil shale can be extracted via surface, underground, or "in-situ" mining, in which kerogen is heated underground and pumped to the surface. All these techniques demand significantly more energy than what''s required for conventional liquid oil, producing more air and global warming pollution as a result.

to Improve Soil quality

The effectiveness of agricultural limestone depends on the degree of fineness because reaction rate depends on the size of the material (surface area) in contact with the soil. Agricultural limestone contains both coarse and fine materials. Many states require 75 to 100 % of the limestone to pass an 8- to 10-mesh screen and that 25%

The Carbon Cycle

The Slow Carbon Cycle. Through a series of chemical reactions and tectonic activity, carbon takes between 100-200 million years to move between rocks, soil, ocean, and atmosphere in the slow carbon cycle. On average, 10 13 to 10 14 grams (10–100 million metric tons) of carbon move through the slow carbon cycle every year.
