Our mission
To provide innovative, tailor-made production solutions that reduce our customers' raw-material budgets and raise service quality at every step of the supply chain — and to grow consistently by investing in technology.
Our story
Markets changed. Our values didn't.
Trieris started with one mission: to exceed customer expectations by providing complete global sourcing services for the biodiesel industry, and to deliver quality in every part of the business. Our operations and markets have broadened since then — into industrial chemicals, machinery and engineering services — but the principles we were founded on still guide every decision.
Customer satisfaction is at the centre of what we do, but service standards alone don't win in the long run. In our business, trust matters. Clients choose Trieris not only for price and service, but because we treat them with respect, deal fairly and deliver on our promises. Our reputation for integrity is our most effective marketing tool — a strong but silent partner in every relationship.
“Trieris is a good company — and one reason is that I am part of it.”
The name
Three banks of oars, one rhythm.
In ancient Greek, a trieres — the trireme — was a fast ship driven by three banks of oars pulling as one. It is a fitting picture of how we work: separate disciplines moving in the same rhythm, toward the same destination. Arrival of the fittest.
