We are looking everywhere in the world a recycle of research ideas and outputs. This is at the expense of huge financial resources and time. It is also against the evolution of ideas and progress of knowledge and development. Therefore, is there any one who has hard facts about the impacts of research recycling on progress of science, social values and economic implications? How can we reshape the current situation?
