Paper is a versatile product and has many uses. It is used for printing, packaging, decorating, writing, cleaning, filter paper, wallpaper, book-end paper, coated worktops, toilet tissue, currency, security paper and several industrial and manufacturing procedures. The global production of paper and paperboard will reach 476 million tons by 2032. Studies estimate that about 42 million trees are cut down daily for paper and other products. It is estimated that in one year, one mature tree absorbs 48 pounds (or 21 kgs) of carbon dioxide. Thus, 332 million metric tons of carbon absorption capacity is being destroyed each year to produce paper. A more sustainable approach to paper production is needed.
Tree-free paper is slowly starting to gain prominence. A wide variety of alternative fibres can replace wood-pulp paper. The sources for tree-free paper include:
* Agricultural residues – for example, sugar cane bagasse, husks, and straw.
* Fibre crops and wild plants – such as bamboo, kenaf, hemp, jute, and flax.
* Textiles and cordage wastes.
There are also non-fibre sources, such as calcium carbonate bound by a high-density, non-toxic polyethylene resin.
The paper industry is highly competitive with low margins and is always searching for cheaper and widely available alternatives. Traditional paper production requires constant planting, cutting and replanting of trees. Although, many paper producers have moved to recyclable paper, it still doesn’t solve the problem of managing forests, as their lifecycle still starts with planting trees. There is also a limit to how many times paper can be recycled. The tree-free paper solves that problem.
Tree-free paper is beneficial for the environment by preventing deforestation. Of course, there is a risk that forest owners may shift the land use to other purposes as they would lose an earnings stream. If the trees no longer need to be planted, there will be a reduction in the use of pesticides and fertilizers. Tree-free paper production creates employment opportunities, generates income, and supports social and cultural values.
