Galactic
The bioplastic which Galactic produces is poly lactic acid (PLA) which is 100% biodegradable
and can be produced from fully renewable resources such as sugar cane, sugar beet, wheat,
maize and cellulose. The resulting polymer can be used for a number of applications including
automotive parts, clothing/textile fibers, food packaging etc. The production process is as
follows:
1. Preparation of the monomeric unit which is lactide (including separation and purification)
2. Ring opening polymerization of lactide to form poly lactic acid
Galactic’s goal is the make PLA into the base raw material in green chemistry development
NatureWorks
This company produces a class of materials called InGeo which is a portfolio of PLA
performance materials. There are 6 classes of InGeo, namely:
- 2 Series: a thermoplastic resin with applications in food packaging and containers.
Transparents. Used mostly for extrusion and thermoforming. 2 available grades:
- 2003D → used for mostly formulated blends on conventional extrusion
equipment
- 2500HP → Viscous and designed to crystallize during processing.
- 3 Series: designed for injection molding applications. Used for plastic cutlery, electronics
casings, outdoor gardening items
- 3001D → unlubricated, high flow grade
- 3052D → lubricated, high flow grade
- 3100HP → medium viscosity for medium flow injection molding applications
- 3251D → lubricated, ultra-high flow grade
- 4 Series: for applications related to oriented films, card stock and graphic arts. There are
different types on offer for different applications
- 4032D → high heat film
- 4043D → general purpose film
- 4044D → reactive extrusion grade
- 4060D → heat seal layer for film
- 6 Series: designed to be drawn into fibers for mono and multifilament products
- 6060D → amorphous low melt for staple fiber
- 6100D → for extrusion into mechanically drawn staple fibers or continuous
filament for use with conventional fiber spinning and drawing equipment
- 6202D → staple fiber spunbond for nonwovens, non-dyed fiber applications
- 6252D → designed for meltblown products for use with conventional and high
pressure die meltblown equipment
- 6400D → industrial mono and multifilament products
- 6752D → Sheath polymer for spunbond applications
- 8 Series (8052D): to be converted into an expanded foam sheet which has great
mechanical properties (strength, lightweight, and suitable for food packaging).

3D series
Currently InGeo produces lactic acid by use of plants such as corn, cassava, sugar cane and
sugar beets. The current R&D goal is to use microorganisms to convert greenhouse gases such
as CO2 and CH4 into lactic acid (thereby skipping the plant step). Then, the lactic acid is
transformed into lactide, which then undergoes polymerization. This entire process produces
80% less greenhouse gases and uses 52% less non renewable energy than traditional
polymers.
Nova Institute
SPLASH - Sustainable Polymers from Algae Sugars and Hydrocarbons (2012-2017)
This project run by nova Institute researches and develops the use of two types of green algae,
namely Botryococcus braunii and Chlamydomonas reinhardtii (to which the polysaccharide
producing gene from Botryococcus will be transferred). This is to develop a new bio based
method for production of polyesters and polyolefins and to turn this into an efficient industrial
sector. The algae exudes: adipic acid from galactose, 2,5-furandicarboxylic acid from glucose,
rhamnose and fucose, 1,4-pentanediol from rhamnose and fucose, ethylene from ‘green
naphtha’, propylene from ‘green naphtha’.
These building blocks are then converted to new condensation polymers such as
poly(ethylene-2,5-furandioate) (PEF) and poly(1,4-pentylene adipate-co-2,5-furandioate). These
can be used for a wide variety of applications such as packaging material and fibers for ropes
and nets.
