-Harden Systems for turning pulp and paper mill waste into value
Every recycled fibre line needs a sludge handling and reject system in order to operate economically. The goal is to minimize losses of process materials, recover and conserve resources (fiber, water, and energy), and minimize waste disposal.
Harden is experienced in providing one-stop paper mills waste shredding and washing solutions for both the pulp and reject lines within paper mills, includes iron removal, cleaning, sorting, drying, baling or granulation.
