Life Cycle Assessment of PVC-U Plastic Window Production

Based on life cycle assessment (LCA), a quantitative analysis and evaluation of resources consumption, energy consumption and pollutant emissions caused by windows production were carried out. The result shows that AP, POCP and GWP are the main contributors of the total environment burden of windows production process, and the proportion is almost 97%. At the stage of windows parts production, the main environmental pressures of windows production process are from windows profiles and glass production process. The result shows that the key of the windows production energy-saving are the windows profiles and glass production process.
