Biodegradable plastics are an irresistible trend.
GSmach is a specialist in complete extrusion lines for bioplastics. We can supply the entire range of equipment for the extrusion and compounding of bioplastics.
1. Complete plant solutions for PLA resins
2. Turnkey solutions for water-soluble packaging bags
1) Biodegradable Additive Masterbatch
2) Biodegradable Plastic: PPC, PABT, PLA, PBS, PCL, TPS, PVA, PVOH
a) Melt PBAT compounding with PLA or PPC
b) PLA/PBS compounding with starch powder
c) PVA compounding with starch
We believe in the potential benefits of the 3Rs (reduce, reuse, recycle) and we promote it, however this is not enough as it does not address the end of life of plastics. We need a fourth R - return to the earth. This would truly return plastics to the earth naturally and complete the life cycle cycle as a whole.
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.
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.
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).
After allowing for all 3R above, the degradable technology then will degrade plastics at chemical and molecular levels – cutting off its long hydrocarbon chains (not physical fragmentation!)- and allowing microbes to consume it and help reduce accumulation at the landfill. It will degrade the plastic within 2-5 years, much better than natural 500-1000 years.
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.
