Indonesian Organic Fertilizer Production Line

Indonesia is one of the world’s largest palm oil producers, generating massive amounts of agricultural waste—including empty fruit bunches (EFB), crop straw, and livestock manure—each year. A leading Indonesian agribusiness group sought a sustainable solution to convert these organic residues into high-quality organic fertilizer, aiming to reduce environmental pollution while creating additional revenue streams. They required a 10 TPH (tons per hour) organic fertilizer production line capable of processing diverse fibrous raw materials efficiently.

We designed a fully automated 10 TPH organic fertilizer production line tailored to Indonesia’s tropical climate and raw material characteristics, with the following core workflow:

1. Crawler Type Compost Turner: First, raw organic wastes (EFB, manure, straw) are formed into windrows. The crawler turner aerates the piles thoroughly, accelerating aerobic fermentation, killing pathogens and weed seeds, and maturing the raw material within 15–20 days.
2. Batching Machine: Matured compost is automatically weighed and proportioned according to nutrient formulas, ensuring consistent fertilizer quality.
3. Double Shaft Mixing Machine: The batched materials are mixed uniformly with microbial agents and trace elements, achieving a homogeneity rate of over 95%.
4. Vertical Crusher: The mixed material is crushed into fine particles (2–3 mm), preparing it for granulation and improving nutrient release efficiency.
5. Drum Granulator + Disc-type Granulator: A dual-granulation system ensures high molding rates. The drum granulator forms base pellets, while the disc-type granulator refines them into uniform 3–5 mm round pellets, ideal for storage and mechanized application.
6. Drum Dryer: Wet pellets are dried to a moisture content of 10–15%, preventing caking during storage.
7. Drum Cooler: Hot pellets are cooled to room temperature, stabilizing their physical properties and extending shelf life.
8. Drum Screening Machine: Pellets are screened to separate qualified products from undersized/oversized particles, which are recycled for re-granulation.
9. Packaging Machine: Finished organic fertilizer pellets are automatically packed into 10–50 kg bags, ready for distribution to local plantations and smallholder farmers.

• High Efficiency: The 10 TPH line processes 240 tons of organic waste daily, converting over 90% of raw materials into marketable fertilizer.
• Cost Savings: Automated operation reduces labor costs by 60% compared to manual composting, while energy-efficient drying/cooling systems cut utility expenses by 30%.
• Environmental Impact: The project diverts over 70,000 tons of agricultural waste from landfills annually, reducing methane emissions and soil/water pollution.
• Economic Benefits: The finished organic fertilizer is sold to palm oil plantations and vegetable farms, generating stable revenue and closing the loop in sustainable agriculture.

“The 10 TPH organic fertilizer line from HH Heavy Industry has transformed our waste management into a profitable business. The equipment runs reliably in Indonesia’s humid climate, and the dual-granulation system produces pellets that are highly popular with local farmers. We are already planning a second line to expand our capacity.”
