HealthOptimizing Recycling: Criteria for Comparing and Improving Recycled Feedstocks in Building Products
Report
Global industry has made progress toward a world in which more efficient use of resources, including recycling, helps to reduce impacts on the natural systems that support life. However, contamination of recycled-content raw material with potentially toxic substances reduces feedstock value, impedes growth of recycling rates, and can endanger human and environmental health.
This paper provides findings and recommendations about how progress in resource use efficiency and recycling can occur along with the production of healthier building products. This paper is based on the review of eleven common recycled-content feedstocks used to manufacture building materials that are sold in California’s San Francisco Bay Area. It provides manufacturers and purchasers of building products, government agencies, and the recycling industry with recommendations for optimizing recycled-content feedstocks in building products to increase their value, marketability and safety.
HealthHealthy Environments: What’s New (and What’s Not) With PVC
Report
This paper was prepared by Perkins+Will, in partnership with Healthy Building Network (HBN), as part of a larger effort to promote health in the built environment. Indoor environments commonly have higher levels of pollutants, and architects and designers may frequently have the opportunity to help reduce or mitigate exposures.
The purpose of this report is to present information on the environmental and health hazards of PVC, with an emphasis on information found in government sources. This report is not intended to be a comprehensive analysis of all aspects of the PVC lifecycle, or a comprehensive comparative analysis of polymer lifecycles. Rather, in light of recent claims that PVC formulas have been improved by reducing certain toxic additives, this paper reviews contemporary research and data to determine if hazards are still associated with the lifecycle of PVC. This research has been surveyed from a perspective consistent with the precautionary principle, which, as applied, means that where there is some evidence of environmental or human health impact of PVC that reasonable alternatives should be used where possible. Furthermore, and more generally, this paper is intended to build greater awareness of this common building material.
HealthEnvironmental Impacts of Polyvinyl Chloride Building Materials
Report
In the last 40 years, polyvinyl chloride plastic (PVC) has become a major building material. Global vinyl production now totals over 30 million tons per year, the majority of which is directed to building applications, furnishings, and electronics.
The hazards posed by dioxins, phthalates, metals, vinyl chloride, and ethylene dichloride are largely unique to PVC, which is the only major building material and the only major plastic that contains chlorine or requires plasticizers or stabilizers. PVC building materials therefore represent a significant and unnecessary environmental health risk, and their phase-out in favor of safer alternatives should be a high priority. PVC is the antithesis of a green building material. Efforts to speed adoption of safer, viable substitute building materials can have significant, tangible benefits for human health and the environment. This report describes the full life cycle of PVC in the contemporary building industry from production to disposal.
