Petrochemical Structure
Products from upstream petrochemical industry Products from downtream petrochemical industry Feedstock Products and applications Natural gas or petroleum Ethylene Propylene Butadiene Benzene Styrene Toluene xylene Polyethylene Polypropylene Polyvinylchloride Polystyrene etc. PE: bag, film, container ethane PP: bag, rope, bottle, insulator PVC: pipe, film propane PS: foam, tape cassette naptha Raw materials for synthetic fiber Costume, cutain, carpet Synthetic rubber Rubber, canvas Raw material for coating, solvent, etc. coating Surfactant Surfactant, shampoo Others Feritlzier, dye, glue

Advantage of Green PE Carbon Footprint: Reduce CO2 emission through its life cycle
21
Green Ethylene made from sugarcane ethanol are able to absorb CO2

Plastic VS Bioplastic Price
Resin price (USD/lb) Green polyethylene Polyhydroxyalkanoates Polylactic acid Starch-based polymers Conventional Plastic Resin price (USD/lb) polyethylene Polyethylene and Bio-polyethylene price are not much different. But every biobased plastic (from sugar cane) ton removes 2.5 tons of CO2 from the atmosphere. Source: Plastic Technology : Argeni

Bioplastics Production Chain
Farmer / Feedstock Producer Monomer Producer Resin Producer Compounder Converter End-Users ปัจจุบันมีการผลิตวัตถุดิบทั้งอ้อยและมันสำปะหลังที่ส่งออกเป็นวัตถุดิบไปยังต่างประเทศมากกว่า 80% จึงเป็นโอกาสในการสร้างมูลค่าเพิ่มแทนการส่งออกเป็นวัตถุดิบเพียงอย่างเดียว มีผู้ผลิตต่างประเทศผลิตแลคติก (Monomer) สำหรับอาหารและส่งออกทั้งหมด แต่ไม่มีการผลิต Polymer ขณะนี้ต่างประเทศกำลังพิจารณาลงทุน โดยใช้น้ำตาลและแป้ง ปัจจุบันมีการผลิตพลาสติก จากปิโตรเคมี นำมาทำเป็น compound resin เพื่อเป็นวัตถุดิบในการขึ้นรูปเป็นบรรจุภัณฑ์รูปแบบต่างๆ เพื่อใช้งานบรรจุอาหาร หรือสินค้าต่างๆ มีกำลังการผลิต 6 ล้านตัน มีผู้ประกอบการมากกว่า 3000 ราย มูลค่ารวม 250,000 ล้านบาท การใช้พลาสติกปัจจุบันก่อให้เกิดปัญหาสิ่งแวดล้อมและการกำจัดขยะ

Bioplastic Investment in Thailand
PTT Chemical invests in NatureWorks PTT Chemical announced today that it is collaborating with Cargill to form a 50/50 joint venture by investing $US150 million in NatureWorks LLC, the world's leading bioplastics manufacturer and supplier of its broad family of renewable Ingeo™ biopolymers made from plants to plastics and fibers markets worldwide. PTT, MCC forms bio-PBS JV PTT Group and Mitsubishi Chemical Corp join hands in establishing the first sugar-based bio-plastic manufacturing plant in Thailand, in their bid to become a green plastic producer and turn Thailand into the "bio-hub" of Asia. PTT MCC Biochem Co Ltd is established as a 50:50 joint venture. The company will start the plant construction in 2012 for commercial operations in late With estimated investment of Bt 7 billion, the plant will be capable of producing 36,000 tonnes of BSA from sugar and 20,000 tonnes of PBS per annum.
