Bayr gathers cotton stalks from Nile Delta farms and turns them into powdered activated carbon for textile dyers and wastewater plants. Farmers get paid for what they used to burn.
Discuss your project →See what we makeWe are a small team from Zewail City who got tired of watching the autumn "Black Cloud" settle over the Delta and decided to do something about the cause.
Lead Egypt's move to a circular economy by turning what rural communities burn and throw away into clean raw material.
Smart waste infrastructure in 10,000 rural communities worldwide by 2035, starting from villages, not cities.
Thermochemical processing, a simple voice-first app and a trusted local network. Proven ideas, applied where nobody has yet.
Cotton stalks are bulky, seasonal and scattered across thousands of small plots. The hard part isn't the chemistry, it's getting the material out of the field.
So we recruit and train local women as Ambassadors, the people households already trust. Our app plans their pickup routes to save fuel, and is designed for low literacy, with voice commands and a plain trade screen.
We keep our own footprint light: we own the logistics and the relationships, and work with processing partners for production.

One product today, made well, with the supply chain to back it up.
Made from cotton stalks for dye removal and industrial effluent polishing. Iodine number 400–700 mg/g, 60–200 mesh, moisture ≤ 5%. Custom particle sizes on request.
An in-app model that plans collection routes across scattered farms, so every trip carries more stalks for less fuel.
Local women who aggregate feedstock from smallholders and earn from every tonne collected.
We're early. Here is the problem we are working on, and honestly where we stand.
The feedstock is structural. It returns every season.
A resource gap that industry can fill.
Built so far: a working MVP and early activated-carbon validation. Still in progress: pilot-scale production, ISCC certification, life-cycle assessment and signed offtake agreements.
