Make paper whiter
Calcium Sulphate, CaSO4 is also known as Gypsum or Alabaster. It is used for making plaster of Paris, dried gypsum and as a filler or glaze in paper making. Medically, it is used to make splints and casts for fractures.
The pulp industry uses lime in various stages of the production process:in chemical pulp production, sodium carbonate is treated with lime to regenerate the caustic soda;in the sulphate process, lime is used to produce a calcium bisulphate liquor capable of dissolving non-cellulose wood elements;lime is used as a bleaching agent for pulp, as well as a flocculating, neutralising and clarifying agent for residual water.
Nitric acid is largely used to prepare ammonium and calcium nitrate, common fertilizers for agriculture.
There is no record of who first recycled paper. It was part of the original paper making process as it developed in Europe. It may have originated earlier with paper making in Asia, but I do not know about this. When paper making was developed, during the Middle Ages, the paper was made mostly from recycled linen rags. At that time, paper was used as a replacement for vellum, which was very expensive, or such materials as papyrus, which decomposed easily. This made paper a valuable product, and any paper that could be recycled was reused in the paper making process.

Beta radiation is used in paper making to measure the density and thickness of paper. By passing beta radiation through the paper, it can detect variations in the paper's properties, helping to ensure quality control during the production process. This technology is non-destructive and provides real-time feedback for adjustments in the manufacturing process.
Calcium carbonate is not typically used in glass making. It is commonly used in the production of cement, mortar, and concrete. Nitrogen, on the other hand, is used in various applications such as in the production of ammonia-based fertilizers and as an inert gas for purging and blanketing in industries like electronics and food packaging.
The theoretical reason for using Ammonium thiosulfate, Dipropylene Glycol, and Calcium sulfate to clean the coating mixture of Calcium carbonate from Paper Notes is their ability to be used as wetting agents.
Every plant can be used for making paper.
Paper bags are made from wood, other fibers or recycled paper. There is no petroleum in the make up of the paper bags. But oil (or electricity produced from oil or coal) is usually used in the manufacturing process and in the transport of the paper bags after production.
