Hydraulic fracturing, or "fracking," is the controversial practice of extracting fossil fuels from hard-to-reach shale deposits. In this process, fossil fuel corporations force these underground shale rock formations to crack and split open by blasting them with a mixture of highly pressurized water, high quality sands, and toxic substances, unleashing …

To model high-quality silica sand extraction rather than sand production, a drying step was added to the process. Based on those assumptions, the carbon footprint is 22.7 kg CO 2eq and CED 339 MJ per metric ton of silica sand. The drying process is only a valid assumption for quartz containing more than 98% silica. However, only a few …
