Located near the city of Tainan in the southwestern part of Taiwan, the Stone Paper Factory is one of a kind, solely using waste leftovers from the construction industry in its production of paper- and packaging products.

How we found it 

We at A Good Company were familiar with the production technique, and were looking for a supplier with the same appreciation for detail as ourselves. Our sourcing team in Hong Kong located the factory, and we researched the company extensively before making contact.
Upon meeting the founder, we came to realize that we had found what we were looking for: a passionate, family-owned company with deep-rooted craftsmanship and a genuine commitment to sustainable product development.

The process and way of working

The Stone Paper Factory has spent two decades perfecting its own unique method to create a beautiful paper-like material from stone, in a dry process that uses no chemicals or water. In close collaboration with A Good Company, the factory produces our range of exquisite, high-quality notebooks, as well all of our packaging materials.

Making paper out of stone is a fascinating process, where leftovers from a neighbouring construction industry, mainly limestone and marble,is crushed into a fine powder of calcium carbonate. The factory only uses leftover residue and isn’t engaged in any mining activities to source its raw material. Calcium carbonate a natural product, and while not renewable it’s abundant and used in many industries, such as construction, traditional paper making, and in everyday products such as toothpaste, medicine and baby powder.

The calcium carbonate powder is then mixed with recycled non-toxic high-density polyethene (HDPE) -- a material that can be recycled almost indefinitely -- to create small white pellets the size of candy. In a 100% dry process -- applying no acids, bleach or water -- the pellets are squeezed into a material that resembles traditional paper. This process is carbon neutral, generates no pollution, and only requires a small amount of power, which the Stone Paper Factory produces from its own solar panels.
