Kierrätyspaperien

Kierrätyspaperien refers to paper materials that have been collected and processed for the purpose of being transformed into new paper products. This process is a key component of paper recycling, aiming to reduce the demand for virgin wood pulp and conserve natural resources. The collection of kierrätyspaperien typically involves sorting them from other waste streams, either at the household level through designated bins or through industrial collection systems.

Once collected, kierrätyspaperien are transported to recycling facilities. Here, they undergo a series of treatments. This often begins with pulping, where the paper is mixed with water to break it down into a fibrous slurry. Contaminants such as plastics, staples, and ink are then removed through various screening and cleaning processes. De-inking is a crucial step for many types of paper, involving the removal of ink to produce a lighter-colored pulp suitable for a wider range of new products.

The cleaned and de-inked pulp is then reformed into new paper sheets. The quality and type of kierrätyspaperien collected can influence the characteristics of the recycled paper produced. For instance, high-grade office paper can be recycled into new printing or writing paper, while lower-grade paper like newspaper is often used for products such as cardboard or insulation. The use of kierrätyspaperien significantly reduces energy consumption and water usage compared to manufacturing paper from virgin pulp, contributing to environmental sustainability.
