Transformativ Infrastructure a competition in innovation concepts How to build the Öresund bridge with zero emissions of GHG? 30 Åsa Lindgren, STA
The two team project I. The Challenge Change in paradigms II. New materials and Design and Nature as an innovator III. Cutting edge techniques and Urban transformation IV. Behind the zero emissions New possibilities for man and nature V. (Not decided but probably an international touch) The winner is presented during this summer. A pre-jury and a top-jury (CEO s, directors) 31
Not just a choice of materials. Upgrading of materials, reuse and recycle Sustainability perspective! Which life cycle? Procurement Digitalization Planning 32
