The Greyhound Group has said it expects to create 100 jobs over the next year.
The waste firm has said it is part of a €35m investment.
It is ramping up its commercial division and waste processing arms in response to the growing economy.
The new jobs will be in sales, marketing, operations and administration.
They will bring the number of company employees to 600.
Group managing director, John Brosnan, said: "We are experiencing rapid growth in our commercial division as the economy continues to grow."
"We are seeing increased interest from multi-site and large site customers, particularly in our offering of high recycling rates at lower costs driven by on-site personnel.
"The building sector is buoyant again after almost a decade in the doldrums and we expect more manufacturing companies to relocate to Ireland post-Brexit."
He added: "Accelerated business activity generates more waste and places greater importance on structured recycling which requires large technologically advanced processing facilities."
