🌱 Circular economy since 2001

A second life
for every cartridge
and every computer.

We buy empty and used toner and ink cartridges, computing equipment, and e-waste. We give materials new purpose — back into circulation instead of landfill.

Ecology & circular economy

Waste that isn't waste

A toner cartridge contains plastic, aluminium, rubber, and small electronic components. In a landfill, it takes hundreds of years to decompose. We save them from this fate.

♻️

Regeneration

Empty cartridges are refilled or handed to certified regenerators — the material returns to production.

🌍

EU export

Cartridges are exported across the EU, where they enter certified recycling and regeneration processes.

Energy savings

Toner regeneration uses 70–80% less energy than manufacturing a new cartridge from scratch.

🔄

Circular loop

The "take–make–reuse" principle instead of "take–make–dispose". Each cartridge can go through the circular cycle up to 7 times.

🏭

Less waste

Every year, over 10 million cartridges are discarded in the Czech Republic. We've been helping to reduce this number since 2001.

📋

Documented responsibility

The buyback is fully documented — we issue records suitable for ESG reporting and corporate sustainability goals.

Our story

Circular pioneers
since 2001

Sontradex s.r.o. was founded as a family business at the end of 2001 — long before "circular economy" became a buzzword. Incidentally, our very first internet business card ran at the nostalgic address sontradex.wz.cz. Since then we've come a long way, but our core mission has remained unchanged for more than two decades: what still has value must not end up in the bin.

We are a Czech, private, fully independent company headquartered in Prague. Our actions have always been guided by one simple principle: what still has value must not end up in the bin.
