01 What we do

We turn brewery side streams into the next generation of circular polymers.

Residue Labs is a biomaterials company. We recover carbon-rich residues from brewing, then engineer them into high-performance PLA biopolymers, a scalable pathway to lower-carbon materials that lets producers turn byproducts into high-value resources.

  1. 01 Source Brewery side streams

    High-quality fermentation residues, recovered before they become waste.

  2. 02 Process Biological conversion

    Recovered carbon is converted and polymerised into lactic-acid building blocks.

  3. 03 Product Circular PLA

    Bio-based, high-performance polylactic acid ready for industrial use.

  4. 04 Market Modern manufacturing

    Packaging, durable goods and the next generation of sustainable products.

02 The process

A closed loop, engineered end to end.

From recovered carbon to finished material and back again, every step is designed to keep value in circulation.

  1. 01

    Recover

    We collect carbon-rich side streams from brewing partners: material that would otherwise be discarded or down-cycled.

  2. 02

    Convert

    Controlled fermentation converts recovered sugars and residues into lactic acid, the molecular precursor to PLA.

  3. 03

    Polymerise

    Lactic acid is polymerised into high-performance polylactic acid, a bio-based thermoplastic.

  4. 04

    Circulate

    PLA enters manufacturing as packaging and products, then returns to the loop through composting and recovery.

Circularity by design: the output feeds the next cycle.

03 The material

High-performance polymer, lower-carbon by origin.

We don't let the input make the output feel cheap. Residue Labs PLA is engineered to perform like a premium biopolymer, derived from high-quality recovered carbon streams.

  1. 01

    Circularity

    Materials should keep their value. We design for loops, not landfills.

  2. 02

    Scientific Precision

    Rigorous, measurable, repeatable. Chemistry leaves no room for guesswork.

  3. 03

    Material Innovation

    We engineer biopolymers that compete on performance, not just principle.

  4. 04

    Technical Excellence

    Industrial-grade discipline from feedstock recovery to finished resin.
