Recycling and Bioplastics
Download Presentations

Last year India consumed around 13 million tons of commodity plastics and generated around 9 million tons of plastic waste. Have you ever wondered what happens to your used toothpaste tubes, Tetra packs, carry bags, sachets, flexible food packaging – these go into municipal landfills or clog the sewerage system.  However, certain waste plastic streams like PET bottles, PP woven sacks, HDPE containers, PVC & PE pipes, automotive bumpers, white goods (to name a few) are recycled and used to partially replace virgin plastics.  

To provide a sense of scale, India consumed more than a million tons of PET resin last year to produce bottles for packaged water and soft drinks. Recycling of plastics has become an environmental necessity as well as an economic imperative to save natural resources (India imports more than 80% of its crude oil and petrochemical inputs). Regulatory pressure from government (like Maharashtra plastic ban, Tamil Nadu plastic lined paper cup ban) has added urgency to the matter. We can provide complete technical consultancy services to set up various types of recycling units.

1)Recycling of Commodity Thermoplastics

a)  Recycled polypropylene pellets (granules) from waste PP raffia woven sacks (end-of-life), BOPP films (post industrial waste), Automotive bumpers etc.

b)  Recycled high density polyethylene pellets (granules) from waste HDPE industrial drums, pipes etc. 

c)  Recycled low density polyethylene pellets (granules) from waste LDPE films (both post-consumer & post-industrial waste)

d)  Recycled U-PVC pellets (granules) from waste U-PVC pipes & window profiles 

e)  Recycled mixed plastic waste pellets (granules) e.g. mixed PP & HDPE / LDPE

2)Recycling of Engineering Plastics 

a) Recycled Nylon compound pellets from end of life carpet backing & fishing nets, post-industrial tyre cord fabric waste, post-industrial nylon filament yarn waste

b) Recycled ABS compound pellets from end-of-life white consumer goods e.g. refrigerator, washing machine, TV casings etc. 

c)  Compounded pellets from mixed recycled ABS & PET

d)  Other recycled engineering plastics like Polycarbonate (PC) and Acrylic (PMMA)

3) Recycling of post-consumer waste PET bottles into value added products

a) Recycled Polyester Filament Yarn (Re-POY) that is processed into draw textured yarn (DTY) used for manufacturing of ready-made garments, inner wear, upholstery, furnishings etc.    

b) Recycled Polyester Staple Fiber (Re-PSF) used in production of polyester yarn, fiber fill, non-woven textiles - e.g.   exhibition carpets, carpet backing, automotive insulation, technical / medical / Geo textiles etc.

c) Extruded Clear Recycled PET Rigid Sheet for thermoformed packaging (consumer electronics, computer accessories)

d) Co- extruded Clear Sandwich PET Sheet (Virgin + Recycled + Virgin) for food contact packaging (dairy & bakery)

e) Recycled PET resin pellets for partially replacing virgin resin in different products

f)  Bottle grade PET Resin (US FDA approved) from waste PET Bottles by means of special process

g) Extruded PET Strapping Tape

4) Recycling of Mixed Plastic Waste (MPW)

We can provide technical know-how to recycle mixed plastic waste (e.g. mix of LDPE & PP or HDPE & PP) with the use of special additive and processing methods.

Bio-based Additives and Plastics

1) Bio Plasticizer to replace phthalate-based plasticizers

Renewable, agricultural, non-edible oil based bio plasticizer is well placed to replace phthalate based and other competing plasticizers in soft PVC compounds without sacrificing product performance at a competitive cost. Castor Oil based plasticizer is an ideal choice due to its abundant availability in India, non-edible oil and its chemistry that enables production of plasticizer with superior functionality. Bio-plasticizers can be also based on cottonseed oil, palm oil, rice bran oil, linseed oil etc.

2) Food Grade Plasticizers

Produced from plant / agricultural based glycerin derivatives. Examples of such food grade plasticizers are Acetylated Monoglycerides (AMG), Acetylated Citric Acid Esters of Monoglyceride (ACMG), Polyglycerol Esters of Fatty Acids (PGE), Calcium or Zinc Stearoyl Lactylate etc.

3) PHA Bioplastics

Poly-Hydroxy-Alkanoates are a family of biobased polyesters that are suitable for even the most challenging food packaging applications. PHAs are biodegradable, readily compostable thermoplastics, produced by microbial fermentation of industrial by-products (molasses, whey, glycerol) and organic waste feedstocks (agricultural waste, waste cooking oils, vegetable waste etc.) Properties of PHA polymers are customizable to the application.

4) PBS and PBAT Bio-degradable Plastics

Polybutylene Succinate (PBS) is a biodegradable and compostable polyester with melting temperature exceeding 100°C, which is important for applications that require a high temperature range. Copolymers of PBS like PBST or Poly (butylene succinate - terephthalate) and PBSA or Poly (butylene succinate - adipate terephthalate) possess good biodegradability along with desirable physical properties.

Polybutylene adipate terephthalate (PBAT) is a biodegradable random co-polymer (co-polyester of adipic acid1,4-butanediol and terephthalic acid). Main advantage of PBAT is that it is a fully biodegradable alternative to LDPE, having similar properties including high flexibility and toughness, allowing it to be used for various packaging applications.
