1. Institute for Environment and Development STØ LCA simulations How can these help us? Example: Energy carriers for LWA production

2. Institute for Environment and Development STØ Simulations can give a good basis for understanding challenges from competitors and prioritising improving options for the production process, as well as recognising future opportunities.

3. Institute for Environment and Development STØ Assumptions Used the same LCA model as for Argex LWA, except… No gas cleaning, kiln (in order to ensure comparison fair) Simulated changing coal energy carrier to alternative (not LP gas as well)

4. Institute for Environment and Development STØ Results Energy consumption

5. Institute for Environment and Development STØ Global Warming Potential

6. Institute for Environment and Development STØ Acidification Potential

7. Institute for Environment and Development STØ Eutrophication Potential

8. Institute for Environment and Development STØ POCP for the main steps in the life cycle
