Abstract:

La production de l'hydrogène à partir de biomasse est actuellement à l'étude mais la méthode de valorisation du biogaz (mélange H2/CO2) par réactions catalytiques, autres que la simple combustion, n'a pas encore été retenue. Par conséquent, le principal objectif de ce travail est d'explorer les autres voies. L'effet du CO2 sur le système catalytique est mal connu et seulement un effet négatif sur la dissociation de l'hydrogène a été mentionné. L'hydrogénation du toluène sur un catalyseur Pt a d'abord été étudiée sans CO2 pour suivre son comportement et éventuellement sa perte d'activité. En pr

Abstract:

The valorization of agro-industrial wastes represents a huge advantage for the transformation industry and the environment. Particularly, biomasses like spent coffee grounds are largely produced worldwide by coffee-based industries and do not require any pre-treatment for their use as raw material for extraction processes. Indeed, exhaust coffee grounds are usually collected in separated containers, either in coffee shops either in vending machines and are already in powder form. Several authors, analyzing chemical composition of spent coffee grounds, demonstrated their potential use as natura

Food wastage represents a massive issue in today's society. It impacts the environment (e.g., climate change, resources depletion, biodiversity loss), society (e.g. food security), and the global economy. All the stakeholders could change systemically to transition towards the circular economy. Corporates must involve leadership, employees, suppliers, and consumers to build a more efficient and resilient system where waste and by-products generation is limited. The unavoidable waste could be valorized to new raw materials to reduce the environmental impact of their disposal. This thesis focuse
