We Don't Buy Limestone.
We Mine It Next Door.

From quarry blast to quicklime loadout in 100 meters—the shortest, most controlled limestone-to-lime value chain in Sulawesi. No middlemen. No quality drift. Just industrial-grade reliability when your operations can't afford downtime.

The 100-Meter Advantage

Why does distance matter?

Every handoff introduces contamination risk.

Every kilometer adds logistical failure points.

Every intermediary dilutes accountability.

We eliminated
all three.

Team

How do we pull it off?

North Morowali, Central Sulawesi

Our quarry-to-kiln distance: 100 meters. That's not a marketing claim— it's engineered vertical integration. Mine, crush, and calcine under one governance structure, one quality protocol, one delivery promise.

The Result?

End-to-End Quality Control

quarry → crusher → kiln under one governance.

Strategic Logistics

~6-10 km to ports; short haul from quarry to kiln (~100 m).

Reliable Volumes

300-350 tph crushing; planned quicklime ~500 TPD (scalable to 1,000 TPD).

Majority Ownership

agile CAPEX, tighter governance, dependable supply.

Our Integrated Value Chain

Upstream: PWA Limestone

  • 97.57 ha C&C-certified operation
  • Sucofindo-validated chemistry: CaCO₃ >95%, CaO >53%
  • Standard sizing: 3/5 cm, 5/9 cm (custom runs available)
  • Direct loading to barges: 6 km to private jetty, 10 km to Pelindo

Downstream: MAC Quicklime

  • Preheater → Rotary Kiln → Shaft Cooler configuration
  • DCS/PLC control with real-time monitoring (temp, pressure, flow)
  • Baghouse emissions system for <50 mg/Nm³ particulate
  • Target product: free CaO >90% (based on PWA feedstock consistency)

On development

Most Suppliers

Buy limestone → truck to kiln (50+ km)

→ quality varies by source
blame game when specs drift

Bintang Logo

Own quarry + own kiln + 100m distance

= one partner to trust, minimalized specs drift, centralized control

Result

  • No finger-pointing across vendors when chemistry drifts
  • No logistics lag between mining and processing
  • No compromise between "fast" and "consistent"
