History[ edit ] Five seminal steps in ancient Chinese papermaking outlined in a woodcut. Pulp for papermaking was produced by macerating mulberry bark as early as the 2nd century in Han dynasty China, where the invention of paper is traditionally attributed to Cai Lun. In addition to mulberry, pulp was also made from bamboo, hibiscus bark, blue sandalwood, straw, and cotton.
On the other hand, crops cultivated to supply material to the pulp and paper industry and forestry exploitation are operations that may involve severe negative impact on man and the environment. Thus analysis of these operations must be included in the EIA document.
This analysis has to address all the potential repercussions of the project very precisely, like the destruction of rain forests, the pollution of rivers and subsurface water, the depletion of biodiversity, the cultural and social risks in affected communities.
It is very relevant for integrated forestry and pulpmill projects, where extensive reforestation plans are set up, to study the consequences of both deforestation and reforestation.
Risks like biodiversity depletion, fires, and erosion are likely to occur and must be addressed. Deforestation and reforestation usually necessitate an assessment of the impact on: The number of non target destroyed trees can be higher than that of target trees.
They can either be eliminated by local species or become weeds, spreading all around without any chance of further control. This erosion usually produces turbidity in water and sedimentation in the river beds. This positive impact has to balance out all negative aspects, in all potential sites.
At this stage it is most important to cross reference the possible impact of the project with the sensitivity of the site see check-list 1. Meanwhile it is important to complete a special check-list for forestry management.PaperAge magazine is the leading source for paper industry news and information about the global paper industry, including pulp, paper, tissue and paperboard manufacturers, and paper converters.

TAPPSA – the Technical Association of the Pulp and Paper Industry of Southern Africa – seeks to further the application of the sciences in the pulp, paper and allied industries and provide means for the interchange of ideas upon scientific and technical matters affecting the industry.
Handbook For Pulp and Paper Technologists (The SMOOK Book), Fourth Edition The Handbook For Pulp and Paper Technologists (The SMOOK Book), is by far the best-selling text to introduce the entire technology of pulp and paper manufacture.
Pulp Fiction will likely hold up generations from now, but the resonance of its title may already be lost to history. Pulp magazines, or “the pulps,” as they were called, once held special significance for lovers of adventure stories, detective and science fiction, and horror and fantasy.
Pulp is a lignocellulosic fibrous material prepared by chemically or mechanically separating cellulose fibres from wood, fiber crops, waste paper, or leslutinsduphoenix.com kinds of paper are made from wood with nothing else mixed into them. This includes newspaper, magazines and even toilet paper.
Pulp is one of the most abundant raw materials.
