Is paper making wood a physical or chemical change?
The process of making paper from wood involves both physical and chemical changes. Physically, the wood fibers are mechanically separated and broken down into pulp. Chemically, during the pulping and bleaching processes, chemical reactions occur to alter the composition of the wood fibers and remove impurities, resulting in the transformation of raw wood material into paper.

What are ways to change the chemical property of paper?
One way is to treat the paper with chemicals that alter its properties, such as by making it water-resistant or flame-retardant. Another method is to expose the paper to high temperatures or radiation to induce chemical changes. Additionally, incorporating additives or coatings during the paper-making process can modify its chemical properties.

What is paper sludge?
Paper sludge is the leftover chemical sludge that is expelled when making paper. This sludge reduces as paper is recycled.
Who found the process of recycling paper?
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.
What chemical in making paper causes cancer?
