2 INTRODUCTION The Coatings Industry in 2013 Uncertain economical conditions. Stay competitive as an industry: a clear need to invest in the development and implementation of new technologies Environmental pressures and regulations: remain the main drivers of the coatings industry in the years to come. 2

3 Sustainable Development "Development is sustainable when it meets the needs of the present without compromising the ability of future generations to meet their own needs." the Brundtland Report (1987) 3

4 Sustainable Resin Production Reduction of the usage of resins Reduction of total layer thickness Improved durability Reduction of the environmental impact of the production process Use of energy / water Emission of CO 2 Replacement of non-renewable resources by bio-based raw materials 4

6 Carbon Footprint Methodology 6

7 Carbon Footprint Methodology (cont.) Cradle to Gate: Raw material selection Transport Energy / heat Waste Resin Manufacturer Cradle to grave: Durability of the coating Cradle to cradle: close the loop and recycle 7

8 Carbon Footprint of Oxidatively Drying Coating Resins 3 Largest contribution comes from the raw materials 2.5 CO2 eq/resin (t/t) Waste Transport Energy Raw Mat 0 SB Alkyd Fatty acid modified PUD Alkyd Emulsion 8

10 Composition of an Alkyd Resin Schematic impression of an alkyd resin used as a binder compound in alkyd paint. The fatty acid chain shown is linoleic acid. Polyols Oils/fatty acids Polyacids 10

11 Raw Materials Used for Alkyd Resins 11

12 Oils and Fatty Acids Limited sources for vegetable oils: Strong competition with: Food & Feed Grain Maize. Production of bio-fuel. Investigate oils from other sources: Valorization of by products from the wood pulping industry Microbial oil (derived from cellulosic waste streams) Algea oil (using CO 2 and waste streams from sugar/potato processing industry) 12
