A Study of Carbon Footprint Evaluation at PP-R Pipe Based on Life Cycle Assessment

摘要

At present, the global warming has drew people's attention to the emissions of greenhouse gases such as CO_2, the essence of which is worrying about the more and more carbon emissions. PP-R pipe has been widely used in production and livelihood, so evaluating the carbon footprint of PP-R pipe is very necessary. This paper evaluated the carbon footprint of PP-R pipe from the production of raw materials to waste disposal, based on the life cycle assessment. The result of the study is that, in the life cycle of PP-R pipe 74.02% of the total carbon emissions come from the production of raw materials. But if using reclaimed materials to replace the total carbon emissions would reduce 52.90%. So an innovative technology of PP-R raw materials producing and using more reclaimed materials are the keys to cut down the carbon emissions of PP-R pipe.
