Step 3: Classify <strong>Waste</strong><br />
<strong>City</strong> <strong>of</strong> <strong>Sunnyvale</strong> <strong>Waste</strong> <strong>Characterization</strong> <strong>Report</strong><br />
This study assigned waste to one <strong>of</strong> ten material classes: Paper, Plastic, Glass, Metal, Electronics,<br />
Organics, C&D, Household Hazardous <strong>Waste</strong> (HHW), Special <strong>Waste</strong>, and Mixed Residue. Materials<br />
were further sorted into 88 standard material categories and six additional uncommon materials to<br />
determine their presence versus absence. These material categories are defined in Appendix A.<br />
To identify additional diversion opportunities, the consultant team also classified material categories<br />
according to their recoverability using five recoverability groups, which were color-coded to make the<br />
viewing <strong>of</strong> the figures and tables clearer:<br />
Recyclable paper (blue) – all paper materials considered recyclable by the project team.<br />
Other recyclables (purple) – all plastic, metals, glass, and other recyclable materials considered<br />
recyclable by the project team.<br />
Compostable/potentially recyclable (green) – all materials considered compostable or potentially<br />
recyclable by the project team.<br />
Potentially recyclable (peach) – all materials where markets are emerging or being developed to<br />
process or recover materials.<br />
Problem materials (brown) –all materials for which there is no existing processing option.<br />
The following table shows the 88 material categories arranged according to material class and<br />
recoverability group.<br />
