Life Cycle Assessment of Pvc-a Polymer Alloy Pipes for the Impacts Reduction in the Construction Sector
The plastics and construction sectors are at the heart of European policies for the circular economy. Polyvinyl chloride (PVC) is the most used polymer in construction products and one of the major applications is piping systems for water distribution. The PVC-A polymer alloy is made blending PVC with chlorinated polyethylene and it is characterized by improved physical properties that allow a reduction in pipe’s thickness. These characteristics enable a reduction in the consumption of resources, but a comprehensive analysis of environmental performance is needed to identify any trade-offs. The aim of this work is to apply Life Cycle Assessment to evaluate two PVC-A piping systems with different gaskets. The study was conducted according to the EN 15804 standard and primary data from an industrial-scale production process were used. An extensive comparison with the main alternatives on the market (PVC-U, PVC-O, PVC-M, and PE) is reported, both referred to 1 kg and 1 meter of pipe.
期刊介绍：
Chemical Engineering Transactions (CET) aims to be a leading international journal for publication of original research and review articles in chemical, process, and environmental engineering. CET begin in 2002 as a vehicle for publication of high-quality papers in chemical engineering, connected with leading international conferences. In 2014, CET opened a new era as an internationally-recognised journal. Articles containing original research results, covering any aspect from molecular phenomena through to industrial case studies and design, with a strong influence of chemical engineering methodologies and ethos are particularly welcome. We encourage state-of-the-art contributions relating to the future of industrial processing, sustainable design, as well as transdisciplinary research that goes beyond the conventional bounds of chemical engineering. Short reviews on hot topics, emerging technologies, and other areas of high interest should highlight unsolved challenges and provide clear directions for future research. The journal publishes periodically with approximately 6 volumes per year. Core topic areas: -Batch processing- Biotechnology- Circular economy and integration- Environmental engineering- Fluid flow and fluid mechanics- Green materials and processing- Heat and mass transfer- Innovation engineering- Life cycle analysis and optimisation- Modelling and simulation- Operations and supply chain management- Particle technology- Process dynamics, flexibility, and control- Process integration and design- Process intensification and optimisation- Process safety- Product development- Reaction engineering- Renewable energy- Separation processes- Smart industry, city, and agriculture- Sustainability- Systems engineering- Thermodynamic- Waste minimisation, processing and management- Water and wastewater engineering
