How we work

A loop, not a line

Material enters at collection and returns there at end of life. Nothing in the process is designed to become waste.

0%
Closed loop
01

Collection

Post-consumer PET is bought from five waste-picker cooperatives across Nairobi at above-market rates, paid same day.

02

Processing

Bottles are sorted, washed, shredded and extruded into fine acoustic fibre. Wash water is filtered and re-circulated.

03

Manufacturing

Fibre is thermo-pressed into rigid modular panels. No water in the forming stage, no added chemical binders.

04

Installation

Our own team fits the panels, and logs each project so the material can be recovered at end of life.

Our commitments

Aligned to four UN goals

We report against the Sustainable Development Goals our work genuinely touches — and stay quiet about the ones it doesn't.

SDG 9

Industry, innovation & infrastructure

We are redefining industrial material flows — proving that high-performance building materials do not require virgin resource extraction, and can be made competitively on the continent that uses them.

SDG 11

Sustainable cities

Cutting urban waste burdens while improving indoor environmental quality.

SDG 12

Responsible production

100% recycled content in, and fully recoverable at end of life.

SDG 13

Climate action

By keeping plastic out of incineration and using low-energy thermoforming, a square metre of our panelling carries a materially smaller footprint than the imported foam it replaces — including the shipping it avoids.

Where we stand

Progress against our own targets

Measured at the end of the last quarter. The gaps are as much a part of the report as the wins.

Recycled content in finished panels100%

Target met and held across every batch.

Collection paid above market rate100%

All five cooperative partners, same-day settlement.

Manufacturing on renewable power34%

Rooftop solar covers daytime load; grid at night.

Panels recovered under take-back12%

Early — the first installations are only now ageing out.

Looking ahead

Expanding capacity, not compromises

Our aim is to be the leading supplier of sustainable architectural acoustics in Africa by 2028 — processing 5,000 tonnes of plastic a year.
