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).
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 ...
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.
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.
The lyocell process uses an amine oxide to dissolve cellulose and Tencel is the only commercial example of this direct-dissolution process, which unlike the viscose process is pollution-free. The 90-92% cellulose content sulfite pulps are used mostly to make textiles (like rayon ) and cellophane .
Cellulose insulating material plants are used for the production of naturally insulating material out of raw material like newspapers, hemp, field grass and so forth.The insulating materials which are produced with this systems, are characterized by low energy input during the production compared to the conventional insulating materials such as mineral wool etc.
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 ...
Cellulose is composed of 75–85% recycled paper fiber, usually post-consumer waste newsprint. The other 15% is a fire retardant such as boric acid or ammonium sulphate. Cellulose has the highest recycled content of any insulation available. For example, fiberglass has a maximum amount of 50% recycled content.
