By being moldable, durable, light, and inexpensive plastic packaging has seen a rapid growth in the use and its disposal is becoming a planetary challenge. Besides sustainable production and consumption globalized trade in waste plastics represents a significant option towards a circular economy. China, who so far represented the greatest importer of this material, recently (2017) implemented a policy banning the importation of most plastic waste and rising global concern regarding the destiny of this enormous displaced material flow.
This project aims to develop a sustainable approach to produce value-added products from waste and biomass. The industrial partner (Enerkem) uses municipal solid waste and other biomass to produce syngas, which is further converted to methanol or ethanol. Currently, the company seeks to enhance this capability by producing other value-added chemicals. One of the key steps in the desired technology is the production of methyl acetate.
The catalytic CO2 reforming process provides a sequestration alternative that holds promise for a viable solution for dealing with industrial gaseous effluents containing greenhouse gases CH4 and CO2. The process converts these gases to syngas (CO and H2) which can be used for synthesis for high value chemicals. The catalyst for the dry reforming process has been developed by Enerkem and is being scaled up by an industrial partner for implementation in an industrial sized reactor.
Ce projet de recherche tend à soutenir l’effort de recherche et de développement ainsi que de formation de personnel hautement qualifié de la Chaire de recherche industrielle en Biocarburants et Biocommodités de l’Université de Sherbrooke. Les objectifs de cette démarche tendent à faire avancer la recherche et le développement de pointe dans le domaine des biocarburants et des biocommodités via 4 plateformes spécifiques.
Sequestering the industrially produced CO2 leads to its capture via the underground formation of stable inorganic carbonates/bicarbonates. An alternate approach is to convert the CO2 into valuable organic products having commercial markets. The incorporation of CO2 as block molecule with which to expand the platform is part of the Enerkem strategy aiming to further improve the use of Carbon from waste. Such strategy is deployable across Alberta.
Gasification of wastes (either urban waste or residues from forest and agricultural operations) at large scale is a challenging operation because of the heterogeneity of the feedstock. Enerkem has addressed such challenge via its state-of-the art Bubbling Fluidized Bed (BFB) technology coupled with secondary Cracking and Reforming that results in high conversion of Carbon to syngas and a quality of the Syngas that makes it suitable for Catalytic Processing. The Enerkem approach provides a sustainable alternative to both landfill and incineration.
