Bio-based
The carbon in PLA comes from this season's crop, not from a reservoir laid down over millions of years. Feedstock is grown, milled and fermented — a supply chain that regrows rather than depletes.
Why PLA
Plastic behaviour,without thepermanence.
Polylactic acid is a biopolymer drawn from renewable plant starch. It moulds, extrudes and prints on conventional tooling — and then, given the right conditions, it goes back to where it came from.

The material
Polylactic acid, in plain terms.
PLA is a 100% compostable biopolymer derived from renewable plant starch — in India, principally sugarcane. It can be anaerobically digested to produce biogas and fertiliser, which is what gives it a genuinely closed-loop lifecycle rather than a slower route to the same landfill.
That adaptability is why it now turns up across packaging, textiles, medical devices and 3D printing — a renewable material that balances environmental sustainability against the economics of actually using it at scale.
- Bio-based: built from renewable plant sugars rather than crude oil.
- Biodegrades under industrial compost conditions — organic recycling, not landfill.
- Chemically recyclable back to its own building blocks and re-polymerised.
- Small amounts in an existing mechanical recycling stream don't disrupt it.
- One of the lowest-cost biopolymers, with real hardness, high clarity and room to scale.
What it gives you
Five things the material does that oil-based plastic cannot.
Lower carbon footprint
Deriving the polymer from renewable biomass takes markedly less energy than cracking and refining fossil feedstock, and the growing crop absorbs CO₂ on the way in.
Compostable
Fully compostable in industrial facilities, and digestible to biogas, biofertiliser or energy.
Recyclable
Designed for end-of-life recovery through both mechanical and chemical recycling routes.
Made in India
Domestic PLA manufacturing shortens the supply chain and supports Indian growers.
Side by side
The same job, a different afterlife.
Where the two materials actually diverge — and where they don't.
Aspect
PLA
Conventional plastic
Feedstock
Renewable plant sugars, regrown and harvested each season.
Fossil crude oil and natural gas, extracted once and gone.
Production energy
Lower energy demand than the fossil-based polymer route.
Energy-intensive cracking and refining.
End of life
Composts industrially; digests to biogas and biofertiliser.
Persists in landfill and environment for centuries.
What it leaves
Breaks down to CO₂, water and biomass.
Fragments into microplastics that stay in soil and water.
Recycling
Mechanical and chemical recycling, back to monomer.
Mechanical only, with quality falling every cycle.
The process
From cane field to compost heap — and back to the field.
Ten steps take a harvested crop to finished resin, and then return what's left to the soil.
01
Sugarcane
Cane is grown and harvested as the renewable feedstock.
02
Sugar
The crop is milled and refined into fermentable sugar.
03
Fermentation
Microbes convert that sugar into crude lactic acid.
04
Purification
Crude acid is refined up to polymer-grade lactic acid.
05
Lactide
Two lactic acid units condense into a cyclic lactide dimer.
06
Polymerisation
Ring-opening polymerisation links lactide into long PLA chains.
07
PLA pellets
Chains are pelletised into resin, ready for converting.
08
In use
Converters mould, extrude and spin it into finished goods.
09
Digestion
After use, thermophilic anaerobic digestion breaks the polymer down.
10
Biogas & biofertiliser
What's left is energy and soil nutrition, not waste.
Biogas and biofertiliser go back to the field — and step 01 begins again.
