How to make plaster out of paper, and other perks of dry separation

Great news! We made plaster out of paper.
We completed the development of a "premix" - an additive to dry building mixes based on our cellulose fiber. It consists of diamite and mineral powder and cellulose obtained from the recycling of composite paper. This additive is used in the production of gypsum plasters and tile adhesives that last for decades. Already today we are starting to test our product in the "field" conditions.

Recycling of composite paper (coffee cups, tetra pak) is one of our key activities. This is a difficult to recycle material, because it consists of several components that need to be separated from each other: paper, plastic and aluminum. The most common method for recycling composite paper is flotation, but this option consumes a large amount of water.

We have learned to recycle composite paper without using a single drop of water. This magic is called "dry defibration method". The technology allows to separate the composite paper into composite materials under the influence of aerodynamic flows. The result of recycling is high quality cellulose.

We examined the obtained "dry" cellulose fiber: its properties are as close as possible to the primary cellulose and exceeds those of waste paper. The inertial separation directly from the dissolution zone allows you to keep the original parameters of the fibers and does not damage them. This means that such a cellulose fiber can and should be used for the production of new goods - and we just got one step closer to it.
