Wood is a natural resource in deficiency. Demand has risen dramatically nowadays and is expected to double over the next 50 years. Forest production is insufficient to meet existing needs, with the result that logging and deforestation has increased across the globe. Direct replacement or “forest” cultivation for timber exploitation also has a negative impact on the ecosystem, which is degraded.
From the above, it becomes obvious that the most effective management and utilization of wood is imperative.
Our company is able to handle various kinds of waste wood such as
- broken and full pallet of all types
- woodworking and woodworking industries and wood industries
- wooden waste from demolitions
- furniture to be rejected
Our company has special wood processing equipment, which saves the volume of wood waste and achieves the best qualitative and quantitative further management.
The natural resources of wood used for pulpwood come from coniferous trees such as spruce leather, pine, fir, larch, hemlock, and deciduous trees , such as eucalyptus, aspen and birch. The paper depending on the intended use is subjected to a similar manufacturing process.
The paper (newspapers, magazines), produced in a way that combines functionality and economy, mainly uses paper pulp as it is intended for ephemeral use and does not require high resistance in special conditions (humidity, extreme temperatures, mechanical stress, .a.). On the other hand, the paper used for writing is manufactured with higher specifications for its resistance to time and environmental conditions and chemical paper pulp is used for this purpose.
Mechanical paper pulp is produced by the mechanical pulping and dehumidification of wood. The fibers are released with as much pulp yield as possible and little component loss (some water-soluble extractable ingredients). The yield ranges from 90 to 98%.
The chemical pulp is produced by chemical pulping of the fibers, that is, a combination of wood chips and chemicals in large containers, known as digesters, where heat and chemicals break down lignin that holds together the cellulose fibers without degrading them. The yield due to this process is quite reduced, ranging from 40 to 60%. Usually used for materials that have to be durable or in combination with mechanical pulp gives the product different characteristics. Greater consumption of trees (wood) is required to produce an equal amount of paper with paper pulp (paper) in relation to engineering. The chemical paper pulp represents about 72% of pulp produced from wood of trees.
Each of these techniques also presents distinct advantages. For this reason, there are few times when a combination of the above processes is applied in order to produce the best possible products. In this case, the process and processing conditions of the pulp are similar to those of the individual processes, but the conditions are milder.
The most common paper recycling processes are:
• The pulp of the old paper.
• A process that combines pulping, chemical and mechanical cleaning, and pulp concentration.
• A procedure that resembles the previous one except that after purification it follows, fractionation of the fibers, concentration and dispersion.
