In reading about alternatives to paper made from trees, I’ve come across paper made from sugar fibrous residue which remains after sugarcane or sorghum stalks are crushed to extract their juice, known as Bagasse pulp. It is currently used as a renewable resource in the manufacture of pulp and paper products and building materials.
Sugar paper is susceptible to humidity for paper, and heat for cups and utensils (heat can cause them to stick together).
From Wikipedia:
“Around 5%-10% of paper production worldwide is produced from agricultural crops, valuing agricultural paper production at between $5 billion and $10 billion. The most notable of these agricultural crops are wheat straw and bagasse. Paper production is the second largest revenue stream from bagasse after electricity cogeneration; higher than ethanol. Using agriculatural crops rather than wood has the advantage of reducing deforestation. Bagasse has the added advantage in that it requires fewer greenhouse gases to collect, compared to harvesting of wood chips, as the fibre has already been transported to the factory for extracting the sugar. Due to the ease with which bagasse can be chemically pulped, bagasse requires less bleaching chemicals than wood pulp to achieve a bright, white sheet of paper. The fibers vary in length depending on the country and cane variety but are typically about 1.3mm to 1.7 mm long. Bagasse fibers are well suited for tissue, corrugating medium, newsprint, and writing paper.
Bagasse pulp and paper mills tend to be smaller than wood based mills although many world-scale factories exist, notably TNPL (Tamil Nadu, India) Century Pulp and Paper (India) and Ledesma Paper (Argentina).

“Paper made from sugar cane fiber is listed internationally as “Friends of Nature” as its raw material, sugar cane bagasse, a byproduct of the sugar industry, rolling over short periods of time. Through the process of developing this fiber paper reduces solid waste and produces a fine paper, biodegradable and recyclable. For the quality of the papers and the environmental benefits obtained, the sugarcane fiber alternative source is the increased demand in the world.”
