Biodegradable Extruder

REDUCE

We should only use what we need. Education, advocacy, incentives as well as disincentives (e.g. paid plastic shopping bags) to promote this idea can be implemented.

REUSE

Product design and education should encourage people to reuse as much as possible. For example in Indonesia, the thin plastic shopping bags are heavily reused as garbage can liner to the point that the thicker garbage liner plastic, which are prevalent in developed countries, do not exist.

RECYCLE

It is critical to continue improve plastic recycling rate; we all should do our best here. However, we need to also recognize there are pragmatic technical (e.g., multi-layer laminated plastic packaging) and economical (e.g., bulky polystyrene as well as other low value items are hard to collect economically) limitations. Plastic also generally cannot be recycled forever (it downgrades).

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.

a) Melt PBAT compounding with PLA or PPC

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
