Environmental Impacts Analysis and Evaluation for Sand

According to the analysis of the I/O flow of the sand casting process, the paper divides the process into five stages. The carbon emission is used to describe the environmental impacts of sand casting, which is defined as energy carbon emission, material carbon emission and direct carbon emission, and then the carbon emission evaluation model is molded.

Environmental impacts of oil sands Energy Education

The environmental impact of the oil sands is an issue that has been extremely divisive. As with the extraction and use of any fossil fuel, negative environmental effects arise as a result of the extraction, upgrading, and processing of bitumen from the oil sands. Although some steps are being taken to reduce the severity of these impacts such as reclamation there are still associated
