What does pulping mean?
Pulping is the process of breaking down materials such as wood, recovered paper, or fruit into a wet, fibrous, or soft mass called pulp. In paper manufacturing, the word commonly refers to an industrial stage in which woody material or recovered fibre is treated so that its fibres can be separated and processed. The same operation can be applied to food, where fruit or vegetables may be pulped for juice, sauce, or preserves. As a verb, pulping describes this activity and is normally seen in technical or descriptive contexts. The term is especially associated with paper mills, where mechanical, chemical, or related methods are used to separate cellulose fibres. Although pulping can sound similar to pumping, the two involve entirely different actions: one produces a soft mass, while the other moves a fluid or other substance through a system.
The process of reducing a material to a soft, wet, or fibrous mass called pulp.

Chiefly used in industrial and technical contexts, particularly paper production and recycling.
To reduce a material to a soft or fibrous mass by crushing, grinding, shredding, or chemically processing it.
"The mill is pulping old newspapers for reuse."
Usually encountered as the present participle “pulping,” describing an activity in progress.
Rare; the process is normally treated as uncountable.
"Separate pulpings of different fibre types are kept in distinct tanks."
Before paper becomes paper, its fibre is pulped—an industrial transformation that turns wood into the material that can catch ink and hold a story.

Where does pulping come from?
“Pulping” was formed in English by adding the suffix “-ing” to “pulp,” creating both a verbal noun and a present participle. English “pulp” comes through Old French pulpe from Latin pulpa, an old term for flesh or the soft interior substance of a plant. Related English words include “pulpy,” while “pulpectomy” and “pulpotomy” combine the same Latin root with Greek elements referring to cutting.
