📊 Data-Led Comparison for Procurement Teams
The bioplastic conversation is full of marketing claims and vague "eco" language. This page compares PLA (polylactic acid) and conventional PET on the twelve properties that actually matter for Indian buyers. feedstock, safety, clarity, storage, cost, and end-of-life. with no cherry-picked wins on either side.
The Full Table
Compiled from IS/ISO 17088 standards, published life-cycle assessments, and our own procurement data.
| Property | 🌱 PLA (Polylactic Acid) | Conventional PET |
|---|---|---|
| Feedstock | Fermented plant sugars (corn, sugarcane, cassava) | Crude oil (fossil, finite) |
| Renewable | Yes. annually harvested crops | No. extracted, not regrown |
| Optical clarity | Crystal clear | Crystal clear |
| Mechanical strength | Comparable to PET for water bottling | Benchmark |
| Food-contact certified | BIS / FSSAI compliant | BIS / FSSAI compliant |
| Storage temperature limit | Stable up to 40 °C | Stable up to 60 °C |
| Carbon footprint (per kg) | ~1.6 kg CO₂e | ~3.4 kg CO₂e |
| Microplastic shedding | Undetectable in independent testing | Documented at ~240,000 particles/L (PNAS 2024) |
| Certified compostable | Yes. IS/ISO 17088 (industrial, 180 days) | No |
| Recyclable | Yes in dedicated PLA stream (limited India infra) | Yes in the standard PET stream (mature India infra) |
| Persistence in landfill | Degrades slowly. no defined timeframe | 450+ years |
| Cost per bottle (India) | 30–60% premium over PET | Benchmark low cost |

Honest Trade-Offs
We manufacture both. This page is not an argument that PLA is always better. it is an honest breakdown so procurement teams can make the right call for their use case.
Deep Dive
A 2024 study published in Proceedings of the National Academy of Sciences identified an average of 240,000 microplastic and nanoplastic particles per litre in commercially bottled PET water, roughly 100 times higher than earlier estimates.
PLA does not shed microplastic particles at rates observed in conventional PET. Independent testing on our production batches confirms undetectable microplastic release across standard storage and handling conditions.
For hospitality, healthcare, and premium brands where guest perception of purity is core to positioning, this is the single most compelling reason to move to PLA.
