Pulp and paper mills have been constantly expanding in Brazil, and to ensure their competitiveness, new processes should be established both in terms of reducing the waste discarded in landfills, as well as the substitution of fossil fuels used in the mills. The present work aims to evaluate ...
including reuse. It is important to highlight that the cycling of wastes in pulp and paper mills is within the circular economy context (Molina-Sánchez et al.,2018). The fibers recovered in the primary treatment can be returned to the mill or commercialized, reducing the generation of solid ...

Pulp mills can use only virgin fibers, waste fibers, or a mix of both. When producing pulp from virgin fibers, the raw materials are first prepared, for example, by debarking and chipping. The next step is the actual pulping process. The primary purpose of pulping is to free the fibers...
(greater than pH 3) processes, such as autohydrolysis with hardwood, can also be accomplished in mild steel equipment typical of pulp and paper mills. Often understated is the value of having a complete chemical and energy recovery system built into the design of every kraft mill in the ...
