ACID FREE PAPER
Acid-free papers are manufactured in an alkaline environment, which prevents the internal chemical deterioration of the paper over time. The calcium carbonate being added as a buffer also makes the paper resistant to the effects of an external acidic environment.

LIGNIN FREE PAPER
Lignin is a product found in cellulose plants. This can be washed out when making the pulp. Lignin can make paper weaker and more likely to discolour. For example, newspaper turns yellow in sunlight because of the lignin in the pulp.

NON-WOOD PAPER
The most common example is Cotton Paper. Cotton is a natural product which, if not re-used, will become another type of wastes. Using cotton in papermaking fully utilizes our natural resources. Rag from used clothing is another common raw materials used for papermaking.
