Compulsory Licensing Of Climate Engineering Patents: How Embracing Technology- And Research-Sharing Strategies Brings Us One Step Closer To Solving Climate Change, Buzz Hardin Dec 2020

Compulsory Licensing Of Climate Engineering Patents: How Embracing Technology- And Research-Sharing Strategies Brings Us One Step Closer To Solving Climate Change, Buzz Hardin

Arkansas Law Review

The impact of climate change spans the globe and includes increasingly severe and dangerous climate events, including coastal flooding, extreme heat and wildfires, reduced crop yield, and decreased food security. In the United States, if the proper steps toward mitigating or reversing the effects of climate change are not taken, it is very likely that the United States will experience substantial damage to its economy, the health of its citizens, and the environment. In response to the challenges presented by climate change, the number of inventions in the field of climate engineering, or “geoengineering,” has skyrocketed over the past several …

Chemical Engineering Undergraduate Honors Theses

The process of mining minerals and elements from ores and rocks creates acid rock drainage (ARD). This drainage is water that contains heavy metals and minerals that can be dangerous for human consumption or damaging to the environment. The mining industry has employed various water treatment methods to prevent these metals and minerals from being discharged into water sources such as ponds, lakes, and streams. Currently, the most used treatment process in the mining industry is a cost-effective highdensity sludge (HDS) process. This method reduces the concentration of metals and elements with the use of lime/limestone. However, the concentration of …

Chemical Engineering Undergraduate Honors Theses

The Moo Pig Sooie’s researched, designed, and economically analyzed a full-scale adsorption column system to be applied in mining processes that leave high amounts of fluoride in their effluent. This system was designed to remove fluoride from water saturated with calcium sulfate, as calcium sulfate is present in high amounts in certain mining processes. Currently, high density sludge (HDS) is commonly employed to reduce fluoride concentrations, but due to solubility limits the sludge treatment cannot lower fluoride below 10 mg/L (ppm). The current enforceable EPA standard for discharged water is at 4 mg/L (ppm), although mining companies anticipate that this …
