Since oil shale ash contains significantly fewer nutrients compared to wood ash, researchers expected the mixed ash to be less effective than the nutrient-rich wood ash. However, in reality, things ...

With over one billion tons of oil shale industry byproducts, Ida-Viru County in Estonia is one of the world's most waste-heavy places. Ash hills are now considered by scientists and industry alike as ...

Oil shale ash is classified as a hazardous waste because it becomes very basic when in contact with water (pH almost 13). However, ash with such a pH is the best fit for construction materials.

Shale oil and gas are not found in the ash layers, but appear to be associated with them, according to Lee. Related: OPEC Deal In Jeopardy As Iran And Saudi Arabia Square Off.

The ash was traced back to volcanoes in what's now California, part of a huge Pacific rim arc that erupted 90-100 million years ago. However, Lee noticed something strange about the ash layers.

Chevron stopped its oil-shale research in Rio Blanco County in February 2012. “The energy markets have evolved since we started the project in 1982,” said Kelly op de Weegh, a Shell spokeswoman.

This time around, he says, the technology for extracting shale oil looks a little more promising than in the past, but it's still largely unproven: Unfortunately, ...
