Preliminary analyses show that several objectives have been achieved, including the transformation of a significant amount of the CO2 released by one of the chimneys, into calcium carbonate, an environmentally safe product. Discussions have already been initiated to define the steps of the second phase. In fact, within the framework of the project to upgrade the Quebec City incinerator, the city expressed the wish to keep on considering the possibility of reducing the CO2 emissions released by the incinerator's chimneys. The final report will be submitted to the environment service of the City of Quebec which will take note of it before submitting a report to the executive committee. The latter will then be able to make the decision which will seem suitable for the continuation of work. This project was made possible by the collaboration of the City of Quebec and the financial contribution of the Federation of Canadian Municipalities through the Fonds d'habilitation municipal vert ("green" municipal housing fund) and the ministGere de l'Environnement du QuDebec (Quebec Environment Department).
