The goal of the ENCETRE 2 project is the valorization of class 1 meat-and-bone meal based on the principle of circular economy.
This valorization involves a first use as non-conventional fuel by the cement industry and then in a second step it is transformed into hydroxyapatite for the depollution of effluents containing heavy metals and finally in a third step is used as fines in materials for road construction or filling of underground cavities.
The ENCETRE 2 project takes place at the intersection of three major problems:
The purpose of the ENCETRE 2 project is to create a valorization chain allowing an industrial and coordinated response to these three problems.
The innovative character of ENCETRE 2 can be found at several levels. The most traditional level is the creation or improvement of processes and formulations. The most strategic level is the integration of the previous level into an integrated chain shared by the project partners.
The LGI2A laboratory operates more specifically in WP 6, which aims to manage and optimize the transport of materials between the various sites (storage of flour, cement kilns, ash transformation, effluent treatment and recovery of saturated reagent).
