Making Paper from Straw

  • Market Potential

  • With a strongly developed agricultural system, China produces nearly 700 million tons of wheat and corn straw per year. Apart from carbon, straw contains trace elements of potassium, silicon, nitrogen, calcium, magnesium, and phosphorus as well as organic matter such as cellulose, hemicellulose, lignin, protein and amino acids. Because of these elements, straw can be a promising natural resource if we develop the right technologies to make full use of it.

    Our company uses the cellulose in straw to make pulp paper and the lignin to make organic fertilizer. In this way, we turn straw stalks into useful resources rather than simply burning them, which would emit more carbon dioxide into the atmosphere.

  • Circular Economy Production Chains

  • (1) The Main Chain-Straw Pulping and Papermaking

    In this chain, we use fiber materials in wheat and corn straw to make unbleached pulp and then manufacture unbleached natural paper from the pulp, which are distributed and sold all over the world.

    (2) The Secondary Chain 1-Pulping Black Liquor Treatment and Recycling

    Pulping black liquor will be treated through evaporative concentration and spraying granulation to produce organic fertilizer for field crops. The mud produced in the wastewater treatment process contains organic matter which can be used in fertilizers. Straw clippings or wood scraps serve as the biological matrix.

  • Significance of Making Straw Paper

  • 1. Making Full Use of Resources and Promoting Circular Development of Agriculture and Industry
    Tranlin has developed ways to use almost every aspect of straw. In addition to papermaking, we also use straw to make organic fertilizer to improve the quality of soil. Our brand of fulvic acid fertilizer is able to retain water and has strong biological properties that will help plants grow well, improving the harvest season while using 20% less of chemical fertilizers.

    2. Protecting Forest Resources and Creating Eco-Friendly Products
    Pulping excess straw reduces carbon dioxide pollution. One ton of straw will emit 1,310kg of carbon dioxide if discarded without being treated but only 0.4kg of carbon dioxide when used for pulping. To produce one ton of straw pulp in place of wood pulp saves 4m2 of wood, which amounts to 0.7mu (about 466m2) of natural forests and 2mu (about 1,333m2) of manmade forests annually. Because we don't bleach our products, our paper is eco-friendly and non-toxic.
