Founded in 1993, PAPIRUS (Production Autonome de Papier Ingénieusement Recyclé à Université de Sherbrooke), or 'Autonomous Production of Cleverly Recycled Paper at the Université de Sherbrooke', is made up of successive classes of students from the Engineering Faculty who hand down the same project over successive semesters: building a machine that will make it possible to recycle the paper waste of a medium-sized business. Although the machine could be described as a mini-recycler, at a length of six meters, width of two meters and height of two meters, it is still rather imposing. The main components of the machine are now completed. The next teams to work on the project will have to automate the mini-recycler and find ways to reduce, if not eliminate the use of chemical products.
