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 chenxj@tianan-enmat.com www.tianan-enmat.com 1
Bio-based and biodegradable Why? chenxj@tianan-enmat.com www.tianan-enmat.com 2
Why? Oil resources are running low and scarce Global carbon cycle is being destroyed Environment is polluted and that is an understatement. chenxj@tianan-enmat.com www.tianan-enmat.com 3

The eco driver Renewable Carbon CO 2 & biomass New biochemical industry Green polymers & chemicals chenxj@tianan-enmat.com www.tianan-enmat.com 5
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 chenxj@tianan-enmat.com www.tianan-enmat.com 6
Important, if not crucial The support of your governing organizations. A clear governmental implication in environmentally friendly issues. chenxj@tianan-enmat.com www.tianan-enmat.com 7
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, chenxj@tianan-enmat.com www.tianan-enmat.com 8
Why did we bring out PHBV? For its characteristics chenxj@tianan-enmat.com www.tianan-enmat.com 9
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 www.tianan-enmat.com 10
