Economic assessment of waste separation processes for the pulp and paper industry
Economic assessment of commercially available, turnkey waste separation processes for pulp and paper operations. The work evaluates methods to recover fibers, metals, and plastics from ragtails and other waste streams, with the goal of improving sustainability performance and reducing waste disposal costs. Recommendations may include sulfur reduction approaches to support wastewater sludge land application where applicable.
Overview
This solution provides an economic assessment of existing turnkey waste separation processes designed for the pulp and paper industry. The processes target recycling of fibers, metals, and plastics from ragtails and other waste streams, with the aim of improving sustainability metrics and reducing waste disposal costs.
Technical specifications
The proposed assessment focuses on commercially available separation methods developed for recycling fibers, metals, and plastics from pulp mill rejects. These turnkey processes are already in operation and can be purchased and integrated into existing mill operations. Key features include:
- Separation of ragtails: Efficiently grinds and separates waste streams from recycled fiber pulping processes.
- Recycling capabilities: Recovers valuable materials such as fibers, metals, and plastics for reuse in production.
- Sulfur reduction methods: In consultation with industry experts, methods to reduce sulfur emissions are recommended, potentially enabling land application of wastewater sludge.
Technology readiness level
The processes assessed in this proposal have reached Technology Readiness Level 9, indicating they are fully commercialized and ready for deployment in industrial settings. This readiness supports rapid integration to achieve immediate sustainability and cost benefits.
