ENVIRONMENTAL LIFE CYCLE ANALYSIS OF CONSTRUCTION PRODUCTS WITH AND WITHOUT RECYCLING. This paper discusses a methodology for the assessment of the impact of construction products on the environment, called "Environmental Life Cycle Analysis of Products (LCA)".


how concrete performs for commercial buildings using life cycle assessment (LCA) methods of determining environmental per-formance. What is Life Cycle Assessment? Life cycle assessment, or LCA, is the investigation and evaluation of the environmental impacts of a product, process or service.

How to Recycle Concrete

Jan 26, 2015 · How to recycle concrete Concrete is part of a recycling category called “construction and demolition” (or C&D) waste. For years, the only place that would take construction waste was the local landfill. Then governments and solid waste management companies got wise to how much space concrete, wood and other construction debris were taking up.

impacts through life cycle assessment (LCA). LCA is an internationally recognized method for measuring the environmental impacts of materials, assemblies or whole buildings over their entire lives—from extraction or harvest of raw materials through manufacturing, transportation, installation, use, maintenance and disposal or recycling.

Carbon Footprint of Recycled Aggregate Concrete

Aug 30, 2017 · Carbon footprint is one of the most widely used tools for assessing the environmental impacts of the production and utilization of concrete as well as of the components derived from it, representing the amount of carbon dioxide and other greenhouse gases associated with this product, expressed as CO2 equivalents. In this paper, carbon footprint was used to compare the environmental ...
