Plastic is one of the best modern human inventions over the past 100 years, bringing exceptional benefits to our lives. However, given its durability and longevity, plastic waste becomes an immense challenge for a greener, better world.

The Challenges

When plastic becomes waste, its durability becomes a problem – it takes plastics 500 to 1000 years to naturally degrade

In its natural degradation process, plastic undergoes physical fragmentation to become dangerous micro plastics

Human behavior and inappropriate waste management can cause up to 8mn tons plastic / year “leak” into the ocean

GSmach Solutions

1) Biodegradable Additive Masterbatch

Compound the Degradable Additive Masterbatch with any plastic such as PE/PET/PP etc. It speeds up the molecular and chemical degradation of plastic, thus helping to solve the massive accumulation of plastic waste.

Our customer Greenhope from Indonesia has this masterbatch with the name Oxium, which is US-patented. Oxium’s proprietary formula is made of naturally available minerals that are non-toxic, non-heavy metals.

Oxium is used as an additive in low dosage towards regular plastic production and has proven to be an effective and serves as an economical solution.

2) Biodegradable Plastic: PPC, PABT, PLA, PBS, PCL, TPS, PVA, PVOH

a) Melt PBAT compounding with PLA or PPC

The melt PBAT material with temperature 240℃ is fed into twin screw extruder by a melt pump, and add the PLA or PPC pellets and chain extender additive into extruder by the loss-in-weight feeder. This is direct compounding which can save 40% energy and better dispersion, comparing with PBAT pellet compounding with PLA or PPC

Needs long L/D for reacting

Needs under water pelletizing system for high output capacity and automatically process

Needs vacuum packing system

Technical Specifications of Extruder:

b) PLA/PBS compounding with starch powder

Premix and long L/D for better dispersion

Special feeder for anti-bridge

Air cooling die face cutting for PLA base, and air cooling strand pelletizing for PBS base

Need vacuum packing system

 
c) PVA compounding with starch

Two stage mixer for premixing and reacting

Special feeder for anti-bridge

Air cooling die face cutting system, need water cooling jacket for die plate

Need vacuum packing system
