Description
This process involves the collection and classification of waste kraft paper, followed by pulping, impurity removal, and screening, after which chemicals are added to prepare the pulp. The prepared pulp is then fed into a forming machine, where it is shaped using molds and wire mesh, and further processed through drying, calendaring, and cutting to produce recycled kraft paper.
The recycling process relies on electricity to power shredding and grinding equipment. The production process requires input of fresh water and steam, and generates energy consumption, waterborne emissions such as CODcr and NH3-N, as well as plastic and metal waste, slag, sludge, and general solid waste emissions.
This dataset is applicable to the process of producing recycled kraft paper from waste kraft paper.
Activity Description
This dataset represents the process of preparing recycled kraft paper from waste kraft paper through shredding, pulping, and forming. It includes energy and material consumption involved in the production process, solid waste generation, and water discharge.
Process Description
Waste kraft paper is pulped after shredding, and recycled kraft paper is prepared through forming, cutting and other processes.
