CDRA releases white papers on fines

The Construction and Demolition Recycling Association (CDRA), Milwaukee, has released a new report about small, particle-sized materials from recycling construction and demolition (C&D) debris to its members, the association announced in a member email. The particle-sized materials, known as fines, are also referred to as recovered screened material in some locations.

Fines usually consist of soil, but also include small pieces of wood, concrete, drywall, rock and other miscellaneous materials.

These documents were created by Timothy Townsend of the University of Florida in Gainesville and his team to provide insight into C&D fine characterization and how to better manage this material.

The first document addresses strategies that can be used by recyclers to create better products using their C&D fines and market them for appropriate beneficial reuse. It was based on examinations of C&D fines samples from across the country. The second document provides a better understanding of the types of asphalt products encountered in C&D, how they are typically managed (including recycling) and identifies the environmental issues that affect recyclability and markets.

Members can log into the CDRA’s members-only page to access the two white papers, which will also be updated in the coming months as Townsend’s team completes further research.

The executive summaries are also available to the public at cdrecycling.org/resources.
