We often recognize new innovative green products here on the Greenest Insulation Blog. There have been a few announced using cellulose for alternative products recently that appear to have promise and worth sharing. Many people are surprised to learn that cellulose is the most common building material in the world, and is applicable to other products. That’s really not surprising when you understand that cellulose forms the cell walls of plants. Wood is cellulose, and wood is the most widely-used building material. The word “cellulose” is a combination of “cellule,” the French word for a living cell and “glucose,” which, of course, is sugar. Obviously there’s nothing exotic or scary here. The most widely used “cellulose” building product continues to be cellulose insulation, which has been around now for hundreds of years.
Cellulose-Based Alternative Styrofoam
This product was recently announced by researches at Washington State University. It is made from cellulose nanocyrstals, which according to the announcement are the most abundant plant material on the planet. There have been other such alternatives to the standard petroleum-based products. Evidently this one has more promise for actually making it to the market in the future.

Spinnova – Making Fabric From Cellulose Instead of Cotton
Spinnova is a company that is developing technology to make fabric from old clothing, agricultural waste and trees. They won a Fast Company’s 2019 World Changing Ideas Award. According to the company, the advantage is reducing the vast amount of water required to grow cotton and the large volume of pesticides used in farming cotton. It also avoids the use of petroleum fossil fuels, which are found in alternate fabrics like polyester. According to the company, they are using wood pulp as the primary raw material but are experimenting with other fiber materials.
