The Institute

Industry and science depend on each other for creative ideas to become practicable solutions. In this context the aim of the institute is the development of ecologically and economically reasonable technical solutions for the energy and environmental sector, industry and service sector.

As a research institute at the Bremen University of Applied Sciences, the institute serves the transfer between business and science. The energy and recycling economy receives new ideas and professional advice, while the Bremen University of Applied Sciences benefits from the practical relevance of the institute via application-oriented research and development projects for the training of students.

The primary task of the institute is the development and evaluation of processes for the generation of regenerative energy, the recycling and cycle management of substances, the efficient use of raw materials as well as the purification of waters, sludge, solid waste and exhaust air. The institute creates expert reports, carries out LCA studies (including carbon footprint of companies as well as of plants, products and processes) and acts as a consultant to companies, associations and public corporations. In the field of recycling and environmental protection the institute carries out measures for further education and organizes conferences. Many of the projects were, and are, carried out in cooperation with companies, universities and colleges throughout the Federal Republic of Germany. Contacts exist to partners in both European and non-European countries through international projects.
