Recycled Pulp
CD BioSustainable provides high-quality recycled pulp and, leveraging our professional R&D capabilities, offers customized product solutions tailored to our customers' needs. By efficiently recycling and environmentally friendly processing of waste paper, cardboard, and other fibrous materials, we not only reduce the pressure on deforestation and landfill disposal but also flexibly adjust our production processes to meet customers' specific requirements.
Recycled pulp, also known as waste paper pulp, is an environmentally friendly paper product made from recycled waste paper. Through processes such as removing impurities, re-pulping, and bleaching, it has similar properties to virgin pulp. The widespread use of recycled pulp not only reduces reliance on forest resources but also decreases carbon emissions, water usage, and energy consumption during the production process. It is an important part of the circular economy and sustainable development.
♻️ Reduce deforestation: Use recycled paper as raw material to reduce dependence on virgin wood pulp and protect forest resources
♻️ Reduce carbon emissions: Compared with the production of virgin pulp, the production of recycled pulp can reduce carbon emissions by about 30%-50%
♻️ Save energy and water resources: The production of recycled pulp reduces energy consumption by about 50% and water consumption by 90% compared with virgin pulp
♻️ Reduce waste emissions: Through the recycling and reuse of waste paper, landfill and environmental pollution can be effectively reduced
| Types | Source | Features | Applications |
| Deinked Pulp (DIP) | Waste office paper, newspapers, magazines, and other printing papers. | After deinking, printing ink and impurities are removed, and the whiteness is high. | Cultural paper (writing paper, copy paper), newsprint, light coated paper. |
| Mixed Recycled Pulp | Mixed treatment of recycled cartons, packaging paper, newspapers, office paper, and other waste papers. | The fiber length is relatively balanced, the strength is moderate, and it is suitable for a variety of industrial uses. | Corrugated boxes, industrial packaging paper, and ordinary cultural paper. |
| OCC Pulp, Old Corrugated Container Pulp | Waste corrugated boxes, packaging paperboard. | The fiber length is relatively long, the strength is high, and it is suitable for high-strength paper products. | Corrugated paper, containerboard, and industrial packaging paper. |
| White Recycled Pulp | High-quality office waste paper, high-grade printing paper. | High whiteness can be bleached to a color close to that of virgin wood pulp. | High-end cultural paper, book printing paper, specialty paper. |
| Food Grade Recycled Pulp | Food packaging waste, paper cups, milk cartons, and other specially treated recycled paper products. | After strict cleaning and purification, it meets food-grade safety standards. | Food packaging paper, disposable tableware, and food bags. |
