A study by a team at the US Naval Research Laboratory found that strong surface waves and currents generated by major hurricanes can produce extreme forces at the seabed that scour the seafloor and cause massive underwater mudslides. Major oil leaks from damaged pipelines could have irreversible impacts to the ocean environment.
Results of a Rice University laboratory study suggests that using foam may maximize enhanced oil recovery (EOR). Oil resides in formations of rock and sand in small cracks and crevices that have proved devilishly difficult to tap. The Department of Energy, the Abu Dhabi National Oil Co.,
Flowback water treatment is a critical sustainability issue for the oil and gas industry. One to five million gallons of water mixed with sand and chemicals are required for the fracking of each well. Using biochar could help oil and gas companies save money and responsibly treat flowback water for reuse.
For dewatering the company has agreements in place with two technology providers and, through inVentures, has access to an organic sieve technology for removing water from the algae oil. In parallel, scientists are also working to develop technology to effectively extract the oil.

Here’s the basic recipe: Blend cement with larger amounts of sand and other aggregates. Currently that means burning coal, coke, fuel oil, or natural gas, often along with waste plastics and tires. Why cement production emits so much carbon Though the terms “cement” and “concrete” are often conflated, they are not the same thing.
