Abstract: 
The pulp and paper industry plays a large role in global manufacturing, which creates significant water consumption and generation of wastewater that is filled with organic compounds and other chemicals. This paper will explore many different aspects of the pulp and paper industry such as raw material sourcing, manufacturing processes, environmental concerns, technological advancements, and the various wastewater treatment approaches. While there are many different methods to approach this wastewater issue, in this paper we will focus on anaerobic digestion, the application of biological aerated filters, and the use of constructed wetlands. The main material utilized in this industry is wood pulp, which undergoes multiple different procedures and processes to create the typical paper products we use every day. These processes, such as pulping and bleaching, create a large number of environmental concerns despite efforts to encourage better manufacturing practices and paper recycling.
