Raw material

To produce quality paperboard, Papirus uses three main raw materials:

1. Pulp

Pulp, the raw material to produce paper, is a pulp made from eucalyptus tree wood chips (small pieces of wood), that later is used in the process of making paper. It can be liquid, that is, sent to the paper mill as a soft pulp, through pipelines, or undergo a drying process and sold in large sheets.

2. Mechanical Pulp

Part of the raw material for paperboard, some also call it mechanical pulp, is obtained from wood through completely mechanized processes, in machines called milling machines, where the right size logs, debarked and clean are pressed against a rotating grinding stone, which is usually synthetic. The final quality of the pulp depends on the wood itself, the type of stone or disk, and how it was milled. The main characteristics of pulp are uniformity, color, cleanliness, level of dewatering, and fiber resistance.

3. Wastepaper

This is the name given to paper scraps collected after they are used. This material is gathered by specialized companies, then selected, baled, and sold to paper mills as raw material. There is no universal classification for these materials, however we can may call it white or satiny wastepaper, water line or white waste, newsprint, corrugated, mixed file stock, first or letterpress, cartons and magazines. At Papirus, wastepaper can be bought from printing companies (waste from printing processes – pre-consumer) or post-consumer wastepaper, selected from paper collectors’ cooperatives.

3.1. Pre-consumer wastepaper – A good example is wastepaper from printing companies or from paper mill production that goes back into the production cycle and does not reach the hands of consumers. Actually, they are industrial waste.

3.2. Post-consumer wastepaper – These include wastepaper gathered at offices, or wastepaper from packaging from dry waste disposal from homes, which are later selected to become superior quality recycled paper. This type of wastepaper alone is very effective to help reduce landfills, and represents 70% of the total paper in the world. Post-consumer wastepaper are those that in some way have already been handled as a product. Through selective collection, paper collectors’ cooperatives select the wastepaper and send them to recycled paper mills, such as Papirus.

Production Process

The process to produce Papirus paperboard starts long before the raw material arrives at the mill. Many people are involved in providing raw material, from the forest—which provides pulp (virgin fiber)—to the paper collectors’ cooperatives, which remove paper from the environment thoroughly and carefully selecting it.

There are basically five major flows possible within that sequence:

Pulp produced from certified forests is delivered directly to Papirus. In this case, raw material will be used in products that include virgin fibers in their formulation, such as Vitasolid.

The pulp is used to produce paper that is sent to printing companies. The broke is collected by Papirus, who re-uses it in the process.

The waste generated by specifiers, (industrial facilities, for instance) is collected by wastepaper resellers, who deliver them to Papirus.

Paper collectors’ cooperatives collect the paper, from material generated by the resellers. Once selected, they are sent to the Papirus production process.

The longest process is the one that includes collecting post-consumer wastepaper: after being sold at points-of-sale, packaging goes to end-users and then becomes waste, which goes through a selective collection process and is re-used by the paper collectors’ cooperatives for recycling.
