Argentina is the fourth largest producer of paper, paperboard and corrugated fiberboard in Latin America. As of the 2004, the sector produced about 1.4 million tons. The production experienced an increase of 11 percent compared to 2003. However, this production only satisfied 67 percent of domestic demand.
The kraft process (also known as kraft pulping or sulfate process) is a process for conversion of wood into wood pulp, which consists of almost pure cellulose fibres, the main component of paper. The kraft process involves treatment of wood chips with a hot mixture of water, sodium hydroxide (NaOH), and sodium sulfide (Na 2 S), known as white ...
In 2006 CELCO/ARAUCO had five pulp mills in Chile and one in Argentina. Apart from pulp mills, CELCO/ARAUCO has 4 engineered wood manufacturing plants in Chile, 2 in Argentina and 2 in Brazil. The company was founded in September 1979 as result of the fusion of Celulosa Arauco S.A. (1967) and Celulosa Constitución S.A. (1969).
Cellulose is the most abundant organic polymer on Earth. [6] The cellulose content of cotton fibre is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. [7] [8] [9] Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and ...
Cellulosic sugars are used as renewable resources for biochemical and biofuels industries and can be used to produce intermediates by fermentative processes. The availability of industrial sugars from renewable resources, in sufficient quantities and at a favorable cost enables the products to be cost-competitive to fossil fuel based products.
It is the most abundantly available raw material on the Earth for the production of biofuels. [1] It is composed of two kinds of carbohydrate polymers, cellulose and hemicellulose, and an aromatic-rich polymer called lignin. [1] Any biomass rich in cellulose, hemicelluloses, and lignin are commonly referred to as lignocellulosic biomass. [2]
A pulp mill in Rauma, Finland Woodchips for paper production. A pulp mill is a manufacturing facility that converts wood chips or other plant fiber sources into a thick fiber board which can be shipped to a paper mill for further processing. Pulp can be manufactured using mechanical, semi-chemical, or fully chemical methods (kraft and sulfite ...
The original production process uses carbon disulfide (CS 2), which has been found to be highly toxic to workers. [2] The newer lyocell process can be used to produce cellulose film without involving carbon disulfide. [3] "Cellophane" is a generic term in some countries, [4] while in other countries it is a registered trademark.
