1 PHBV production in China, an industrialization of bio-based and biodegradable plastics Oct 13-15, Hangzhou Xuejun Chen Tianan biological material Co., ltd, Ningbo, China 1

2 Bio-based and biodegradable Why? 2

3 Why? Oil resources are running low and scarce Global carbon cycle is being destroyed Environment is polluted and that is an understatement. 3

4 Global carbon cycle CO 2 Biomass / Bio-organics >10 6 years 1-10 years Polymers Chemicals fuels Chemical industry Fossil Resources petroleum, natural gas Courtesy of Prof. NARAYAN chenxj@tianan-enmat.com 4

5 The eco driver Renewable Carbon CO 2 & biomass New biochemical industry Green polymers & chemicals chenxj@tianan-enmat.com 5

6 Ways to overcome the problem Reduce the use of oil resources Use available and renewable resources Use bio-based materials, widely Reclaimed system, utilize repeatedly Set new scientific standard systems 6

7 Important, if not crucial The support of your governing organizations. A clear governmental implication in environmentally friendly issues. chenxj@tianan-enmat.com 7

8 Some have been working on it Who? NatureWorks, BASF, Novamont, Rodendburg, BIOMER, Dupont, Metabolix, SHOWA Highpolymer, MITSUI Chemicals, Mitsubishi GAS Chemicals. What? PLA, ECOFLEX, PCL, PHA, PBS, Mater-Bi, BIOMAX, Thermal-starch, 8

9 Why did we bring out PHBV? For its characteristics 9

10 PHBV characteristics Fully bio-based with abundant starch resources in China, it is also Fully biodegradable in standurd composting conditions in half year. We mean 100% biodegradable. It can endure temperatures up to 140 o centigrade. Biological compatibility. It proves to be a stronger and more powerful barrier to any outside influence than other bioplastics. chenxj@tianan-enmat.com 10

11 Main PHA researching units at present: American: Metabolix, small scale, (planed to up) P&G, middle scale, (stoped?) Brazil : PHB INDUSTRIAL S/A company, about 50 ton/year Japanese : Mitsubishi GAS Chemicals, about 10 ton/year Germany: BIOMER, small scale, Netherlands: Agrotechnology & Food Innovations, small scale,..etc chenxj@tianan-enmat.com 11
