PAPER is based on wood, a natural and renewable material. Paper is one of the most recycled products in the world and epitomises the circular economy model of make, use, recycle and reuse.
Paper processing from wood based
Nowadays, the production process for paper made from virgin wood fibers is very energy- and water-intensive. Cellulose fibers, which are the basis for paper products, must be separated from lignin, hemicellulose, and resins by boiled in the sulphate process with sodium hydroxide and sodium sulphide at temperatures around 170 °C/175 °C, under high pressure for two to three hours. The paper then has to be bleached using chlorine dioxide or oxygen, hydrogen peroxide or ozone.
The processing paper from wood-based.
The grass paper processing
- Reducing the grass by a bale breaker. (fiber length between 500 mm and 10 mm)
- Removing impurities and foreign or extraneous substances by means of a cyclone.
- Reducing and fibrillating the grass in a fiber mill with fraying.
- Screening and sifting the grass by means of a circulating-air separator.
“Grass paper” seems to be the better alternative. Its production process without the use of chemicals.
