Spent Lime (Lime Mud) Recycling & Beneficial Reuse
We help pulp & paper mills, water treatment facilities, and manufacturers move non-hazardous spent lime (lime mud) into qualified reuse outlets. Typical destinations include soil stabilization, cement and aggregate applications, and process neutralization—always in line with local regulations and outlet acceptance criteria. Share what you have and how it’s handled today; we’ll come back with options, simple pricing, and a pickup plan.
What We Accept
Material & sources: lime mud from causticizing (pulp & paper), softening residuals from water treatment, calcium-rich process fines
Forms: dewatered filter cake/presscake, wet slurry, air-dried powder/fines
Typical ranges: slurry ~10–30% solids; cake ~30–70% (ranges vary; photos and past test results help)
How it’s packed: roll-off boxes, lined bunkers, end-dump loads, vacuum tanker for slurry, supersacks for dry material
Volumes: pilots to multi-load programs; best economics at full truckload (FTL) and recurring lanes
What We Don’t Accept
Hazardous waste, unknown contents, or materials with restricted contaminants beyond outlet limits
Mixed debris/municipal waste in loads
Unmanageable free liquids without appropriate equipment/access
How It Works
Tell us what you have
Where it comes from, whether it’s more like a cake or a slurry, rough amount per week/month, a few photos, and any past lab results you already have.We map a reuse path
We’ll propose practical options (e.g., stabilization, cement/aggregate uses, neutralization). If needed, we help arrange sampling/testing to confirm placement.We book the trucks
End-dump for cake/dry, vacuum tanker for slurry; we handle appointments and paperwork.You get confirmation
We’ll confirm where it went; monthly diversion summaries available on request.
Logistics & Coverage
Nationwide pickups • End-dump / walking floor for cake & dry • Vacuum tanker for slurry • Typical lead time 5–10 business days after go-ahead • Site-safety and access rules honored
Industries We Serve
Pulp & paper mills • Municipal & industrial water treatment • Chemical & mineral processors • Ready-mix/aggregate partners • Environmental & civil contractors
Documentation & Compliance
Generator non-hazardous determination and basic characterization (e.g., moisture/solids, pH; metals/TCLP when required)
COI, W-9, NDA available
Chain-of-custody and scale tickets where applicable
Outlet acceptance testing coordinated as needed
Case Example
Once per quarter a packaging manufacturer accumulates a truckload worth of off spec or slightly damaged rolls. They send us their inventory sheet, we bid it out to multiple buyers in our network and rebate the company the best price received. The company is comfortable utilizing floor space to store a full truckload because they know once they do, Waste Optima will move it quickly for a good price.
FAQs
Do you pay for spent lime or is there a haul-off fee?
Typically a cost (though cheaper than landfill) depending on moisture/solids, consistency, distance to outlets, and local demand.Is testing required?
Often. We’ll review any past results and arrange sampling/testing when an outlet needs it.Can you handle slurry?
Sometimes. We can use vacuum tankers for slurry. If you can thicken or dewater it, trucking costs usually improve.What’s the minimum pickup?
Pilots are possible. Pricing is best at FTL and on recurring schedules.Can it be used for land application or agriculture?
Only where permitted and accepted. We’ll route to appropriate outlets based on location and analysis.
