Méthodes numériques liées à la distribution d'alumine dans une cuve d'électrolyse d'aluminium

Thomas Frédéric Hilke

Metallic aluminium plays a key role in our modern economy. Primary metallic aluminium is produced by the transformation of aluminium oxide using the Hall-Héroult industrial process. This process, which requires enormous quantities of energy, consists in pe ...

A combined hydrothermal gasification - solid oxide fuel cell system for sustainable production of algal biomass and energy

François Maréchal, Jan Van Herle, Christian Ludwig, Shivom Sharma, Hossein Madi

Hydrothermal gasification (HTG) is a promising technology that allows the recovery of nutrients from wet biomass with simultaneous production of an energy-rich gas. In this work, wastewater effluent (leachate) obtained from a composter sanitary system oper ...

Time-Continuous Phosphorus Flows in the Indian Agri-Food Sector: Long-Term Drivers and Management Options

Claudia Rebeca Binder Signer

Phosphorus (P) is a major agricultural nutrient and, in its mineable form, a potentially scarce resource. Countries with limited physical access to P should hence develop an effective national P governance. This requires analyses of trends and variations i ...

Towards sustainable sanitation: Identifying and mitigating microbial health risks in the production of urine-derived fertilizers

Tamar Kohn, Simon Schindelholz, Timothy R. Julian

Sanitation systems that systematically recover and reuse waste can promote social enterprise, reduce discharge of harmful nutrients, pathogens and other contaminants to the environment, replace synthetic fertilizer sources, and increase access to sanitatio ...

Impact of nitrogen inputs on multiple facets of plant biodiversity in mountain grasslands: does nutrient source matter?

François Gillet

Questions: What is the impact of nitrogen (N) inputs on the vegetation of mountain permanent grasslands? Beyond the effect of fertilizer quantity (total and available N supply), is there a specific effect of fertilizer quality (the various N sources) on th ...

Hygiene considerations during the collection, storage and processing of source-separated urine into a marketable fertilizer

Tamar Kohn, Simon Schindelholz, Manfred Schoger

Laboratory and field studies along with inactivation data from the literature are used to model bacteria inactivation during urine storage and struvite production. The model is used to evaluate urine storage and struvite drying under the fluctuating temper ...
