recycling old books
Amid global resource scarcity and increasingly stringent environmental laws, recycling traditional paper has become a crucial direction in the papermaking industry. Book paper, as a structurally stable, high-fiber-content paper type, is gradually becoming an essential source of recycled pulp. Compared with conventional waste paper materials like corrugated cardboard (OCC), magazine paper (OMG), or old newspaper (ONP), recycling old books not only reduces the volume of books sent to landfills but also strikes a favorable balance between environmental benefits and economic feasibility.
Anyang Machinery, with over 20 years of experience in papermaking equipment manufacturing and system integration, offers a one-stop pulping and re-papering system solution tailored for book paper recycling, assisting customers in building efficient, eco-friendly, and low-energy pulp production lines.
Features of Book Paper
Book paper mainly refers to recycled old books, textbooks, notebooks, bound documents, etc. Most of them are made from high-grade chemical or mechanical pulp. Their characteristics include:
- Thicker and stiffer paper suitable for recycled printing and office-grade cultural paper.
- Mostly hardcover books, textbooks, educational supplements, art books, etc., with no or light coating—ideal for de-inking.
- Some contain glue bindings, saddle stitching, plastic covers, and other impurities requiring specialized pretreatment equipment for removal.
- Major sources include schools, libraries, printing houses, and recycling centers.
- Suitable for producing recycled writing paper, cultural paper, packaging paper, and pulp-molded products.
Why Recycle Book Paper?
Old books (including magazines and archival paper) are an excellent source of high-quality recycled fiber:
✔ Long fibers: Book printing paper is often chemically pulped, giving stronger fiber strength than ordinary waste paper.
✔ Low impurity rate: Binding adhesives can be targeted for removal, making it easier to clean than mixed paper.
✔ Environmental premium: Cultural-grade paper aligns with ESG trends, enhancing product value.
✔ Mature de-binding: De-inking difficulty is higher than magazines but lower than packaging paper.
Most old books, like textbooks, bound magazines, or hardcovers, are no longer suitable for resale or reuse. By book disposal recycling, large numbers of outdated books are diverted from landfills. Compared to virgin pulp, recycled book paper pulp saves energy, reduces emissions, improves de-inking efficiency, and contains fewer contaminants.

Anyang Machinery’s Custom Book Paper Recycling Solution
Raw Material Pretreatment System
Intelligent sorting line – Removes non-paper impurities like bindings and plastic covers.
Adhesive separation technology – Low-temperature pulping and thermal dispersion systems efficiently break down spine glue.
Archival shredding option – Includes secure destruction modules at the pulping stage for sensitive documents.
Core Pulping Processes
▶ De-inking process (for high-brightness pulp)
Book paper → Hydrapulper (pH controlled) → Flotation de-inking cell (special agent) → multi-stage fine screening → hydrogen peroxide bleaching.
Yields 82–85% pulp with brightness ≥ 75% ISO.
▶ High-strength process (for packaging board)
Book paper → Chain pulper (fiber-protective) → High-consistency dirt removal → thermal dispersion → pulping refinement.
Tensile strength increases by 20% vs. standard waste pulp.
Finished-Product Oriented Transformation
Cultural-grade paper: newsprint or recycled printing/copier paper (requires de-inking + bleaching).
Packaging materials: eco box liners or molded trays (via high-strength process).
Specialty paper: decorative base sheets or flame-retardant paper (with functional additives).
Exclusive Support for Book-Waste Projects
Raw material testing – Free fiber analysis and adhesive content testing, tailored pretreatment solutions.
Glue processing equipment package – Includes low-temp pulper (to prevent adhesive melting), heat dispersion unit (grinds glue to <0.2 mm), and micro flotation cell (secondary glue removal).
Compliance assurance – Archival paper treatment meets ISO 15713 confidentiality-destruction standards; EU REACH-approved ink residue control.
