5 Pigments Division Locations Greatham (UK) Billingham (UK), Group HQ (Grimsby (UK)) Woodlands, Houston (USA) NAFTA Sales Calais (France) Teluk Kalung (Malaysia) Kuala Lumpur, (Malaysia), APAC Sales and TS&D Lake Charles (USA) JV with Kronos Scarlino (Italy) Huelva (Spain) Umbogintwini (South Africa)

6 TiO 2 Pigment Industry Overview TiO 2 Pigment - Markets by End Use TiO 2 Pigment - Markets by Region 9% 13% 12% 28% 22% 57% Paint/coatings Plastics Paper Other 29% North America W Europe APAC ROW 30% TiO 2 Pigment Capacity by Producer % world prod'n DuPont Cristal Tronox Huntsman ISK Kronos Others Rockwood ~65% production from 5 producers

7 Opportunities at Greatham Sustainability is a key part of Division and Site strategy TiO 2 process is energy intensive and Greatham is the largest site in the Division History of improvement (e.g. waste heat boilers) Significant quantities of low temperature heat are available Land is available for development (subject to planning permission)

8 Low grade heat available Exhaust steam 3 process locations Atmospheric pressure steam 30% of heat is recovered and used there is an opportunity for the other 70% for which there is currently no use Cooling Ponds 2 ponds 50C water, cooled to 40C using cooling towers 8MW load each

9 Issues Limited capital investment available Short payback times required (typically <2 years) No further site requirement for low temperature heat we are using the maximum possible Few opportunities to modify the production process to reduce heat consumption / raise efficiency this has been our focus over the past years Therefore seeking new opportunities to re-use heat meaningfully

10 Main workstreams Carbon Trust Assisted CMEE Study Overall site energy supply options Low grade heat options, e.g. Organic Rankine Cycle Steam re-compression Tri-generation Other possibilities Horticulture Bioculture

11 Organic Rankine Cycle Aiming to develop technology for use on steam Large-scale New technology, with associated risk High capital costs Would probably need financial assistance to become viable

12 Steam re-compression Could re-compress atmospheric back to LP steam Analogous to mechanical vapour re-compression as used in the sugar industry High capital cost (compressors) Possible technical issues Limited LP steam use on site, therefore limited scope

13 Tri-generation Process utilises industrial refrigeration units for -20C duties Technology fairly well developed but few installations Possibility to install tri-generation site-wide Fuel/Heat -> Power, Heat & Chilling

14 Other Possibilities Horticulture Heating for glasshouses, CO 2 also required Large land areas required High investment cost for developer Developers seeking low-cost energy Bioculture Perhaps most applicable for our heating water (low approach temperatures) e.g.algae for bio-fuels? Technology is still in its infancy

15 Conclusions Huntsman Pigments is actively exploring opportunities for low-grade heat re-use Most options appear to involve high capital cost and risk Companies need assistance : Toolkits/Consultancy to find the best options Financial incentives Lower-risk options Matching of heat producers with potential heat users (industrial synergy)
