BUSINESS OPPORTUNITY
Activated carbon is an indispensable consumable in water purification, beverage decolonization, industrial wastewater polishing, and gold cyanidation recovery circuits throughout Eastern Indonesia. Utilizing the exceptionally hard, dense cellular structure of NTT coconut shell charcoal, this facility deploys rotary activation kilns operating at 850°C–1,000°C under controlled steam injection to develop massive internal microporosity (iodine adsorption value 900–1,100 mg/g). Locating in KIB provides legal industrial zoning for high-temperature thermal processes, secure water supply for steam generation, and proximity to regional mining and municipal water treatment buyers across Eastern Indonesia.
The business model focuses on increasing margins over raw charcoal: procure coconut-shell charcoal from centres in Kupang Regency/Rote and granular fractions from briquette plants at KIB, activate it to open adsorption pores, then sell it in airtight sacks to industrial and export buyers.
BUSINESS OPPORTUNITY
Activated carbon is a mission-critical consumable with rising demand across municipal water treatment, mining gold extraction, and industrial air pollution control. NTT’s hard, dense coconut shell charcoal represents the gold standard raw material for steam activation. Locating the activation plant in KIB positions producers near Eastern Indonesia’s mining operations and export sea lanes.
Laboratory testing confirms that coconut shell charcoal from dry tropical NTT exhibits higher fixed carbon (>78%) and superior mechanical attrition resistance than peat or wood carbons. Bolok Industrial Park Profile
Kupang’s maritime connections provide direct freight routes to major mining operations in Sumbawa, North Maluku, and Papua, cutting delivery lead times compared to Java suppliers. KIB development plan · Reference not yet attached
KIB provides the formal industrial zoning required for operating high-temperature rotary kilns (850°C–1,000°C) with comprehensive emissions scrubbing. Bolok Industrial Park Profile
Most activated carbon manufacturing in Indonesia is located in North Sumatra and Java, incurring significant shipping costs when supplying mining projects in Eastern Indonesia. Operating in KIB establishes a direct regional supply base with lower freight, access to local raw charcoal, and export access via Tenau Port.
BUSINESS OPPORTUNITY
The plant utilizes high-density coconut shell charcoal sourced from coastal island clusters across East Nusa Tenggara and Maluku.
| Materials & Requirements | Procurement Source | Quality & Key Specifications |
|---|---|---|
| Granular Coconut Shell Charcoal (Carbonized Shells) | Rural carbonization producers in Flores, Timor, Rote, and Alor. | Fully carbonized, moisture < 12%, volatile matter < 15%, free of stones, sand, and unburned husks. |
| High-Pressure Saturated Steam | Captive industrial steam boiler fueled by biomass wood pellets or excess carbonization gas. | Clean saturated steam at 6–8 bar for high-temperature rotary kiln injection. |
| Industrial Process Water & Acid Solutions | KIB estate water network and chemical suppliers (hydrochloric acid for acid-washing grades). | Treated industrial water for cooling, washing, and steam generation. |
Raw charcoal procurement peaks during the dry season (April–November). The activation plant operates continuously 24/7 on three shifts throughout the year.
Raw charcoal arrives at Bolok harbor by sea or via Trans-Timor road freight, unloading directly into covered raw material bays at KIB.
Raw coconut shell charcoal accounts for 50%–60% of total cash operating costs. Optimizing kiln thermal efficiency and steam recovery directly protects operating margins.
BUSINESS OPPORTUNITY
KIB provides legal heavy industrial zoning, high-power electrical infrastructure, and immediate port access for global containerized exports.
BUSINESS OPPORTUNITY
Investors can deploy a direct-fired or steam-activated rotary kiln system (3,000–5,000 tonnes/year) complete with post-activation screening and acid-wash circuits.
Refractory rotary activation kiln, high-pressure steam boiler, rotary cooler, multi-deck screening system, acid-washing digestion tanks, afterburner emission scrubber, and bulk packing lines.
Upgrading local coconut shell charcoal into technical-grade activated carbon multiplies commodity value by 4x to 6x, serving high-margin captive gold mining and water treatment markets across Eastern Indonesia.
BUSINESS OPPORTUNITY
Bolok Industrial Park (KIB) prepares Phase I with a total area of 191 hectares under clean & clear Right of Management (HPL) land titles with flexible plot sizing, alongside ready-to-lease standard industrial warehouses. The facilities below represent the core estate infrastructure provided by KIB, while tenant-specific production machinery and specialized civil/utility works remain the investor's scope.
Heavy manufacturing plots in KIB Zone I with substantial buffer zones and direct access to utility water and power distribution lines.
Prospective investors are advised to consult with the KIB management team regarding exact plot sizes, standard warehouse technical specifications, electrical power capacity, and water flow rates prior to concluding detailed feasibility studies.
The management team of PT Kawasan Industri Bolok (Perseroda) assists local, national, and international investors (Timor-Leste, Australia, China, etc.) from initial site inspection through to leasing and operational licensing.
