Industry 4.0 is a buzzword now. New digital technologies and artificial intelligence are changing what we do at home, work and on the move. They are increasingly important to innovation, optimisation, and in boosting competitiveness and growth. Perhaps a lesser-known benefit of Industry 4.0 is that it helps companies slash costs via more efficient use of materials, water and energy, reducing their waste streams and environmental footprint. In this very first edition of EREK Quarterly we focus on role of Digitalisation or Industry 4.0 in improving resource efficiency. We provide inspiration to SMEs from the expert we interviewed, practical examples from companies, information on support offered by government, and a host of other relevant tips and information.
