To ensure recycling most of the waste material produced, communal waste, paper, plastic, glass and tins are separately collected and disposed of. Energy saver light bulbs are used in the classrooms and in the dormitory. We print documents only when it is necessary, the offices primarily use recycled paper. Much of the study material is provided by the PRTA and can be used repeatedly.
Apart from printed handouts, lecturers frequently use electronic presentations at the lectures and make much of the study material accessible from the webpage of PRTA. In many cases students are provided with the opportunity to submit electronic essays instead of printed ones.
