recycling processing embodied energy and carbon

What is embodied energy in building? Level
Embodied energy is the total energy required for the extraction, processing, manufacture and delivery of building materials to the building site. Energy consumption produces CO2, which contributes to greenhouse gas emissions, so embodied energy is considered an indicator of the overall environmental impact of building materials and systems.

Embodied Energy/Carbon in stuff Qeng Ho
Embodied energy is the energy used to make something and embodied carbon is the carbon generated in the process. This is often compared to operational energy/carbon and the full 'cradle to grave' life cycle analysis (LCA) needs to include end of life processing as well.

Composites recycling: Gaining traction : CompositesWorld
Current commercial methods for eliminating the resin from the carbon fibers are pyrolysis (thermal treatment) and solvolysis (chemical treatment). Although pyrolysis requires thermal energy to burn off the resin, and can cause fibers to char, the energy of pyrolysis represents only a fraction of the embodied energy of carbon fiber.
