The VDI Centre for Resource Efficiency is a competence centre for small and medium enterprises (SMEs) that is funded by the German Ministry for the Environment and the Association of German Engineers. It aims to promote resource efficiency concepts to reduce natural resource consumption and increase competitiveness of German SMEs in manufacturing and construction. The VDI has over 150,000 members across 12 societies and 60 technical divisions and produces around 200 new guidelines per year. Global raw material usage has risen significantly from 35 billion tonnes in 1979 to an estimated 120 billion tonnes by 2050, driven by population growth and increasing prosperity. Resource efficiency can help SMEs reduce material costs, which typically account for over 50% of costs in manufacturing.
