This article delves into the reasons why viscose is bad for the environment, exploring its production process, the chemicals involved, and the broader ecological consequences of its manufacture and disposal.
Introduction to Viscose
Viscose, also known as rayon, is a semi-synthetic fabric that is made from purified cellulose, typically derived from wood pulp. The production of viscose involves several chemical-intensive steps, starting from the harvesting of trees to the final spinning of the fibers. This complex process not only consumes significant amounts of energy and water but also generates substantial amounts of waste and emissions. The appeal of viscose lies in its ability to mimic the feel of natural fibers like silk and cotton, making it a popular choice for clothing and textiles. However, the environmental cost of producing viscose far outweighs its aesthetic benefits.
The Production Process of Viscose
The production of viscose is a multi-step process that begins with the harvesting of wood. Trees are cut down, and their wood is processed into pulp. This pulp is then treated with chemicals to break down the lignin, a natural glue that holds the wood fibers together, and to purify the cellulose. The most common method for producing viscose involves the use of carbon disulfide, a toxic chemical that can have severe health and environmental impacts. After the cellulose is dissolved in carbon disulfide, it is forced through a spinneret to create the fibers, which are then washed, dried, and spun into yarn.
Chemicals Used in Viscose Production
The use of carbon disulfide is particularly problematic. This chemical is known to be highly toxic, causing a range of health problems from skin irritation to neurological damage. Workers in viscose factories are at significant risk of exposure, and the chemical can also contaminate waterways and soil, affecting local ecosystems. Additionally, the production process involves other chemicals like caustic soda and sulfuric acid, which contribute to the overall environmental footprint of viscose production.
