Abstract
Countries around the world are advocating “energy conservation and
carbon reduction” programmes. According to previous research, waste
concrete and brick recycling, saves material and conserves energy, it aids
carbon reduction.
This study is based on the carbon footprint guidelines to assess the
product’s life-cycle of carbon dioxide emissions in each stage. There are no
International rules in the concrete product category yet, so the system
boundary and calculation of the product categories is not established. This
study through the research methods, and establish a recycling model to assess
the recycling of waste concrete and brick in different ways to reduce carbon
emissions.
Three products evaluated in this study were high-pressure brick, CLSM,
aggregate. This study investigated the recycling - product of the
manufacturing process, and collect plant data to calculate the carbon
emission products. The study based on these data to explore factors affecting
carbon dioxide emissions. Finally, the study provides the proposed method of
reducing carbon dioxide.
