Municipal solid waste incineration bottom ash (MSWI-BA) is a residual material generated during the waste incineration process. Typically, it is utilized as a substitute for sand and natural aggregates in constructing roads and concrete pavements. Before its application, it undergoes a maturation process which involves exposure to the atmosphere for at least 18 weeks.

This project focuses on expediting the maturation of MSWI-BA through an accelerated carbonation process. The goal is to enhance its engineering qualities and promote environmental sustainability.

The objective of the PEPs team is to quantify the environmental impacts (consumption of various resources) caused by the production of the product resulting from this research throughout its entire life cycle (from raw material extraction to the end of the product's life including its manufacturing, installation, and use). These results will be compared to those of an alternative scenario of reference products already present on the market.

The approach will also be adapted from a carbon balance perspective, allowing the highlighting of savings generated based on potential markets for various materials designed during the project, compared to traditionally used materials or end-of-life pathways for renewed recycled products.
