BrasilPackTrends2020 168 qual ity and new technologies Among thebiodegradablematerials, therearesome fossil source polyesters. Consist of poly(caprolactones), polyesteramides and some aliphatic and aromatic copolyesters.Thosematerialsare,many times, associated in blends with biopolymers, especially starches. BASF sells an aromatic-aliphatic copolyerster from fossil source (poli(butylene adipate-co-terphthalate) – PBAT), biodegradable and compostable, called Ecoflex. Other family of products that combines Ecoflex and PLA has been named “ecovio” by BASF, for coating of cellulosic materials. In partnership with Ingredion Incorporated (once called Corn Products International), BASF developed a polymer that combines the Ecoflex with corn starch-based polymer, called Ecobras, with more than 50% of renewable source raw material. A family of regenerated cellulose-based films that has gained some expression in the market of biomaterials is the NatureFlex, by InnoviaFilms. The products are manufactured from wood cellulose, on the same concept as the cellophane, although it is actually compostable material, certified in accordance with the industrial composting standard EN 13432 (2000) and ASTM D 6400 (2012). The company Novamont® has developed and sold the Mater-Bi technology, a family of biodegradable and compostable thermoplastic biopolymers, starch- based from non-transgenic source (usually corn). The company DuPont offers thermoplastic starch-based resins, under the name of Biomax TPS – thermoplastic starch compostable. Cereplast Compostables is a family of starch-based resines, compostable, available for the market of disposable plastic cutlery, films and blown packages. It can be used in blends with the PLA Ingeo. The PLA is thermoplastic aliphatic polyester produced from the fermentation of the dextrose and later polymerization of the lactic acid in a polylactide. It is one of the most commercialized biopolymers in the package market due to its availability, competitive cost and easy conversion into film or rigid packages. The NatureWorks is one of the main worldwide manufacturers of PLA from oleaginous crops. In USA, corn has been used as a source of starch/sugar. Biopolymer Ingeo acquired certification of biological based product from the BioPreferred program, by the USDA. BioPreferred confirms that, at least, 25% of the carbon content is from biological base. In Europe, the company PURAC is a leading manufacturer of PLA. The PHA family of polyester includes the poly(hydroxybutyrate) –PHBanda variety of copolyesters, biodegradable and compostable. The world producers are just a few, including Procter & Gamble.The family of PHA biopolymers from the company Metabolix is commercialized under the brands Mirel and Mvera. In Brazil there is a pilot factory of PHB and of the copolymer poli(hydroxybutyrate-valerate) – PHBHV, products from the Biocycle family manufactured, by the company PHB Industrial, using sugar cane. The recyclable biopolymer is an option that allow the revalorization and the preservation of energy and raw material. In Brazil, Braskem adopted that concept for the production of a biopolymer, a renewable source biopolyethylene. In 2010, they started producing the Green Polyethylene, similar to the commercial grades of high density and low linear density polyethylene, to be processed in conventional equipment, for manufacturing recyclable packages. The resin is produced frombioethanol obtained from sugar cane. The main step of the technology is the transformation of the hydrated bioethanol into ethylene. The product has a validation of the company Beta Analytic, which determines the amount of carbon 14 of the material and, from that, determines the percentage of raw material provided from renewable source. That approach has also been adopted by Coke at PlantBottle (Figure 6.32), that is recyclable, allowing the return of the raw material to the productive cycle with recycling. The PET bottle is produced with 30% of renewable source raw material, which means that the monoethylene glycol comes from sugar cane ethanol – BioMEG. The remaining 70% are composed by terephthalic acid (PTA) that, with the BioMEG, forms the PET resin. So far, the monoethyleneglycol (MEG) used in PET bottles was from fossil source. Coke and the Indian company JBF Industries announced the construction of a factory for the BioMEG resin in Brazil, in Araraquara/SP, that might start operating from 2015.
