VIVOMER / PHA BIO-POLYMER BUSINESS — COMPLETE PROCESS & STARTUP GUIDE
1. AGRICULTURAL WASTE SOURCING
First, identify suitable agricultural and plant-based waste or by-products.
Examples:
- Sugarcane-derived waste/by-products
- Rice-processing by-products
- Corn/plant-based waste streams
- Food-processing by-products
Process:
Waste supplier identification
↓
Supplier agreement
↓
Collection
↓
Quality checking
↓
Transport to facility
2. FEEDSTOCK PREPARATION
The collected agricultural material is converted into a consistent feedstock suitable for microbial fermentation.
Steps:
Raw material receiving
↓
Cleaning
↓
Size reduction
↓
Moisture adjustment
↓
Feedstock preparation
↓
Storage in controlled conditions
Goal: Create a consistent feedstock that microorganisms can efficiently use.
3. MICROBIAL FERMENTATION
The prepared feedstock is introduced into a controlled fermentation system containing suitable microorganisms.
Process:
Prepared feedstock
↓
Microorganism culture
↓
Bioreactor / fermenter
↓
Controlled feeding
↓
Fermentation
During fermentation, microorganisms convert the available carbon/feedstock into PHA (Polyhydroxyalkanoate).
4. FERMENTATION CONTROL
The fermentation process is continuously monitored.
Main parameters:
- pH
- Temperature
- Oxygen / aeration
- Agitation
- Feedstock concentration
- Fermentation time
The objective is to maintain the conditions required for consistent polymer production.
5. BIOMASS RECOVERY
Once fermentation reaches the required stage, the microbial biomass containing the polymer is recovered.
Process:
Fermentation broth
↓
Biomass separation
↓
Concentration
↓
Polymer-containing biomass
6. PHA POLYMER RECOVERY
The polymer is recovered from the microbial biomass.
Process:
Polymer-containing biomass
↓
Cell disruption
↓
Polymer separation
↓
Purification
↓
Washing
↓
Drying
OUTPUT:
PHA BIO-POLYMER
7. POLYMER FORMULATION
The recovered PHA is formulated according to the required application.
For example:
Bottle
→ suitable flexibility + strength + processing characteristics
Cap
→ suitable stiffness + dimensional stability
Container
→ suitable strength + appearance + barrier performance
Process:
PHA polymer
↓
Formulation
↓
Compounding
↓
Material testing
8. PELLET PRODUCTION
The formulated polymer is converted into pellets.
Process:
Bio-polymer formulation
↓
Extruder
↓
Polymer melting
↓
Extrusion into strands
↓
Cooling
↓
Pellet cutting
↓
Drying
↓
Screening
↓
Packaging
FINAL MATERIAL:
BIO-POLYMER PELLETS
These pellets become the input material for downstream plastic-processing equipment.
9. PRODUCT DEVELOPMENT
Now choose the actual product.
For example:
100 ml cosmetic bottle

For suitable bottle designs
Blow moulding can be used where the material/product design is compatible.
11. QUALITY CHECK
Every production batch should be checked for:
- Dimensions
- Weight
- Strength
- Surface finish
- Leakage
- Closure fit
- Colour consistency
- Product performance
Then:
Quality approval → Packaging
12. COMPOSTABILITY / END-OF-LIFE TESTING
Test the actual finished product for the environmental claims you intend to make.
Check:
- Biodegradation
- Disintegration
- Composting performance
- Ecotoxicity
- Relevant chemical requirements
For India, applicable compostable-plastic requirements and testing should be checked against current CPCB requirements and relevant standards such as IS/ISO 17088:2021.
13. PACKAGING
Approved products are packed according to customer requirements.
Process:

16. STARTUP INVESTMENT — SIMPLE MODEL
OPTION 1 — START WITH MANUFACTURING TIE-UP
Approx. ₹2–7 lakh+
Use an existing plastic manufacturer.
You provide:
Material + mould + product specification
They provide:
Machine + factory + operator + production
OPTION 2 — OWN PRODUCT MANUFACTURING UNIT
Approx. ₹15–40 lakh+
Investment goes into:
- Machine
- Mould
- Chiller
- Compressor
- Electrical setup
- Factory setup
- QC
- Material
- Working capital
OPTION 3 — OWN PHA PELLET MANUFACTURING
This requires a much larger biotechnology/manufacturing setup involving:
Feedstock → Fermentation → Polymer recovery → Purification → Formulation → Pelletizing
A pilot-to-commercial facility can require multi-crore investment, depending on capacity and technology.
