The pulp and paper sector has become one of the most significant industrial sectors in the world due to its economic benefits. After primary metals and chemicals sectors, the pulp and paper industry produces the third-largest quantity of wastewater. With regard to environmental feedbacks, ongoing legal requirements, and energy efficiency measures, pulp and paper mills have recently encountered difficulties managing the ensuing pollutants. This study identify pulp and paper mill wastewaters properties, quantities and discuss the recent developments of affordable methods dealing with pulp and paper mill wastewaters. According to the results of the current study, employing integrated methods which is a mixture of treatment techniques may be more advantageous from an economic and environmental standpoint in order to reduce environmental contaminants and energy recycling

establishment has increased which resulted in economic growth in the 21st century, causing global water pollution and water shortage problems. one of the major consumers of energy and natural resources, including water, wood, fossil fuels, and electricity, as well as a significant source of pollutants released into the environment, is the pulp and paper industries. After primary metals and chemicals sectors, the pulp and paper industry produces the third-largest quantity of wastewaterIt produces 42% of global industrial wastewater
