Buildings Life Cycle Assessment (LCA) | Concrete

Life cycle assessment (LCA) seeks to quantify the environmental impacts over the infrastructure life cycle by identifying the costs during each phase. LCA can be used to obtain credits in certification systems like LEED, but traditional LCA methods can be time, resource, and data-intensive. For complex systems like residential buildings, these

Background Document for Life-Cycle Greenhouse Gas Emission

Unlike many of the other materials for which EPA has developed GHG emission factors (e.g., aluminum cans, glass bottles), concrete is assumed to be recycled in an "open loop" - i.e., concrete is recycled into a product other than itself, namely aggregate.17 Therefore, the GHG benefit of concrete recycling results from the avoided emissions

Life cycle assessment and embodied carbon

Closed loop recycling describes the recycling of a product into an identical product, for example recycling a steel beam into another steel beam. Closed-loop recycling poses relatively small methodological problems in LCA, whereas open-loop recycling can incur major allocation problems. Basically, open-loop recycling creates a new, larger

Concrete Pavement Recycling Series: Concrete Pavement

Concrete recycling has been used extensively in Europe since the 1940s and in the US since the 1970s (Darter et al. 1998). At least 43 states now perform concrete recycling for paving applications. Annual production of RCA in the US from all sources (both pavements and demolition debris) was recently reported at about 140 million tons (CDRA ).
