The cost-effective solution for used garnet disposal — exclusively from GMA and proudly supported by Sandblast Solutions Inc.

Disposing of spent abrasive media is usually expensive and logistically difficult. But it doesn’t have to be.

That’s where the GMA Garnet Return Program comes in — a smart, environmentally friendly way to dispose of your used garnet while keeping your jobsite compliant and cost-efficient.

At Sandblast Solutions Inc., we’re proud to be a distributor of GMA Garnet, and we help our customers access this valuable program.

What Is the Garnet Return Program?

Instead of landfilling your spent garnet, you can return it to one of GMA’s permitted collection points. GMA reprocesses the garnet in its state-of-the-art facilities, adhering to strict environmental and product standards.

Collection Points Are Available In:

• Fairless Hills, PA
• Cincinnati, OH
• Coos Bay, OR
• Houston, TX

How It Works – Just 3 Steps

1. Submit Your Sample for Testing
   - Send a 100-gram sample for TCLP testing (RCRA 8 Metals) at a certified third-party lab
   - Send a second sample to GMA for a Sieve Analysis to confirm it’s reusable
2. Submit a Returned Garnet Profile Form
   - Once testing confirms the garnet is safe, complete the profile form
   - GMA will issue a return authorization
3. Pack & Ship Your Used Garnet
   - Use bulk bags or discuss other options with your Sandblast Solutions rep
   - Ship to the nearest GMA collection facility

Why It Makes Sense

• Lower disposal costs than hazardous waste or landfill
• Compliant with environmental regulations (TCLP, RCRA)
• No hidden fees or surprise transport charges
• Reduces your waste footprint while promoting circular material use

FAQs

Q: What does GMA do with the used garnet?
A: GMA reprocesses it to the same standards as freshly mined garnet, ready for industrial reuse.

Q: How do I get garnet out of my waterjet tank?
A: You can shovel it manually or use an automated removal system. Ask your waterjet OEM or contact us for removal solutions.

A: Bulk bags are most common, but we’re happy to help coordinate a method that works for your site.

Q: Will GMA buy the garnet back?
A: No — but it’s usually cheaper to return garnet through this program than to landfill it.
