Spotlight on Salt

As a coastal-based company focusing on regional excess soils, we see a lot of salt-laden input material at our Resource Regeneration Facility. And it’s not just the marine-adjacent digs—even upland soils below a certain depth can contain salt. As you can imagine, given its high solubility, salt readily washes off coarse aggregate and into GRT’s water treatment system where we can safely manage it.

But GRT has one client that sends us exceptionally salty material (a much as 16,000 ppm chloride), and for that project, we continue to develop, refine, and improve our process to remove the salt from our output clays, which are still sometimes saltier than we’d like (since that salty water holds more tightly to fine clay particles than to coarser soil particles).

Why mention this? Two main reasons:

1. GRT are constantly engineering, experimenting, and improving our processes to respond to client needs and maximize our waste diversion. Do you have an unusual excess soil situation? Call us to discuss. Maybe we can solve it together.

2. Our clients can rest assured that all GRT output products are amply sampled and only delivered to end of life sites and facilities that are approved or permitted to receive them. But our clients only pay one fixed price at input (whether we get all that salt out of the clay or not). Isn't that reassuring?
