Online expert interview: "What is stone paper?"

On Friday 19 March 2021, our online expert interview with Hunter Bliss from Pebble Printing Group took place on the topic of "The future with stone paper".

Stone paper is 80% calcium carbonate and 20% polyethylene in publishing applications such as books, and 60% calcium carbonate and 40% polyethylene in the paperboard version. It can generally be considered a substitute for regular wood paper. Compared to conventional wood paper, however, this substrate offers many advantages: it is resource-saving, tear-resistant, waterproof, has a high degree of whiteness and consumes about 70 % less Co2 in production than normal paper. If you want to learn more about this interesting substrate, you can watch the video recording of the interview here.

Have fun watching it!



Our city groups

Since the beginning of 2019, the Gutenberg Society has wanted to expand its activities and involve its internationally distributed members more closely by founding locally active city groups. The cooperation of like-minded people needs points of contact, which we want to make available. Above all, personal encounters provide the opportunity to expand and deepen knowledge about the areas of interest through contacts. To this end, we have found some committed members who organise and carry out events on their own premises in the name of the Gutenberg Society. Ernst Reif made the start in Munich and launched the first events in April 2019. He was followed by Mario Derra in Gernsheim ( and Hans Josef Altmann in Velbert-Langenberg (

Further information about upcoming events can be found under News.
