Hydraulic Mulch
Hydraulic mulch is comprised of small pieces of cellulose fibers, which can be made completely from wood waste or recovered paper. It stabilizes soil, prevents wind and water erosion, and provides protection and warmth for seeds, helping them grow. Through hydroseeding, a mixture of water, seeds, and hydraulic mulch is sprayed over bare soil to quickly promote plant growth.
Recommended Recovered Materials Content Ranges:
EPA's Recovered Materials Advisory Notice (RMAN) recommends recycled-content levels for purchasing hydraulic mulch as shown in the table below.
| Product | Material | Postconsumer Content (%): | Total Recovered Materials Content (%): |
|---|---|---|---|
| Paper-Based Hydraulic Mulch | Paper | 100 | 100 |
| Wood-Based Hydraulic Mulch | Wood and Paper | -- | 100 |
¹The recommended recovered materials content levels are based on the dry weight of the fiber, exclusive of any dyes, wetting agents, seeds, fertilizer, or other non-cellulose additives.
