Waste Characterization Report

Waste Characterization Report — Composition Analysis

The Waste Characterization Report provides a detailed composition breakdown of each wood waste load processed through the 905WOOD Digital Refinery. Unlike the binary clean/treated determination of the Compliance Gate, this report quantifies the specific composition of the waste stream including wood species distribution, treatment type identification, and contamination percentage by weight.

The characterization covers: estimated percentage of clean dimensional lumber (SPF — Spruce/Pine/Fir), engineered wood products (OSB, plywood, MDF), treated wood by treatment type (CCA, ACQ, copper azole), painted or stained wood, and non-wood contaminants (metal fasteners, concrete, drywall). This granular breakdown informs both regulatory compliance and feedstock quality decisions.

For clean loads entering the pyrogenic biocarbon pathway, the characterization report verifies feedstock specifications: less than 10% moisture content, 2-4mm chip profile suitability, and absence of treatment chemicals that would compromise biochar quality. For contaminated loads, the report quantifies the specific contaminants present to inform proper disposal routing.

The Waste Characterization Report supports 905WOOD's industry-leading 60%+ diversion rate by enabling precise sorting decisions that maximize the volume of clean wood directed to biocarbon production versus landfill. In an industry where typical diversion rates range from 15-25%, this level of characterization is the enabling technology that makes higher diversion economically viable.
