Biomass Pellet Production Line in Indonesia

RICHI MACHINERY

Overview

Indonesia, as a nation rich in agricultural resources, generates vast quantities of biomass residues annually. To capitalize on these renewable resources and contribute to the country’s growing energy needs, a large-scale biomass pellet production line was initiated in Surabaya, East Java. The project was developed by a local renewable energy solutions company with extensive experience in sustainable energy and agricultural waste utilization.

The primary aim of this biomass pellet project is to produce 100,000 tons of biomass pellets per year, utilizing locally available residues such as rice husks, corn stalks, and sugarcane bagasse. These materials are abundant in Indonesia and present both an environmental challenge and an economic opportunity when not properly managed.

The project was designed not only to address energy demand but also to reduce agricultural waste, mitigate environmental pollution, and create economic opportunities for local communities.

Project Background and Client Profile

Client Overview

The client is a local Indonesian company specialized in biomass and renewable energy projects. With prior experience in managing agricultural residues and energy production, the client identified a significant opportunity in converting waste into high-value biomass pellets.

Rationale for the Project

Indonesia produces over 100 million tons of rice annually, generating tens of millions of tons of rice husks. Similarly, corn stalks and sugarcane bagasse are abundant in East Java, Central Java, and neighboring regions. Traditionally, these residues were either burned or left to decompose, contributing to environmental pollution, including greenhouse gas emissions and soil degradation.

The client envisioned a solution that would:

Convert agricultural waste into high-value biomass pellets.
Provide renewable energy sources for local industries and households.
Generate new employment opportunities in rural areas.
Align with Indonesian governmental policies promoting clean energy and sustainability.

Strategic Choice of Location

Surabaya Industrial Zone was selected for several reasons:

Proximity to Raw Material Sources: Within 50–100 km of rice mills, sugar factories, and corn processing facilities.
Infrastructure: Reliable electricity supply, water resources, road networks, and logistics access.
Market Access: Ability to supply both domestic and export markets efficiently.

Production Capacity and Output

The biomass pellet production line in Indonesia is designed for:

Annual Output: 100,000 tons
Hourly Capacity: 10–12 tons per hour
Calorific Value of Pellets: Approximately 4,500 kcal/kg
Applications: Power generation, industrial heating, and household energy supply

Raw Materials Analysis

Overview

Indonesia is rich in biomass resources, but the quality, moisture content, and seasonal availability vary. The biomass pellet production line in Indonesia project carefully evaluates raw material sources to ensure stable supply and consistent product quality.

Raw Material Types and Sources

The straw rice husk pellet plant project primarily utilizes three types of raw materials:

Material	Annual Supply (t/a)	Moisture Content	Source	Notes
Rice Husks	50,000	12–15%	Local rice mills	High calorific value, consistent availability
Corn Stalks	30,000	15–18%	Corn farms	Requires chopping and drying before pelletizing
Sugarcane Bagasse	20,000	18–22%	Sugar factories	Fibrous, requires grinding and pre-treatment

Storage and Preprocessing Considerations

Silos and Storage: Materials are stored in covered silos to prevent moisture absorption and microbial growth.
Blending: Materials are blended in specific ratios to optimize pellet quality and calorific value.
Seasonal Buffering: Storage capacity ensures continuous production despite seasonal harvest fluctuations.

Energy, Water, and Environmental Management

Energy Consumption

Electricity: 2,500,000 kWh/year, sourced from the municipal grid.
Natural Gas or Diesel Fuel: Limited use for drying, depending on availability.

Water Consumption and Wastewater

Annual Consumption: 50,000 tons, mainly for staff use and minimal equipment cooling.
Wastewater Treatment: Domestic wastewater from staff is treated using onsite septic systems, then reused for irrigation in surrounding areas, ensuring zero discharge to nearby rivers.

Emission Control

The facility is equipped with:

Baghouse dust collectors on all grinding, pelletizing, and transfer points.
Stack heights of 15 meters for organized emissions.
Estimated annual dust emissions: <200 tons, mostly recycled back into production.

Noise Control

Noise sources such as hammer mills and pellet mills are enclosed in soundproofed areas. Operational schedules are managed to minimize disturbance to neighboring industrial facilities.

Production Process Overview

The biomass pellet production line is divided into several key stages, carefully designed to ensure efficiency, product quality, and minimal environmental impact:

Raw Material Procurement: Sourcing agricultural residues from nearby farms, rice mills, sugarcane factories, and corn processing facilities. Materials are selected for consistency, low moisture content, and high calorific value.
Preprocessing: Initial cleaning and sorting to remove impurities such as stones, soil, or metal fragments. Materials are also stored in silos to buffer seasonal fluctuations.
Grinding: Materials are processed in hammer mills to reduce particle size to less than 5mm, ensuring uniformity and improving pellet density.
Drying: Ground materials are dried in rotary drum dryers to reduce moisture content to 10–15%, optimizing pellet formation and durability.
Pelletizing: Using advanced flat-die and ring-die pellet mills, the dried biomass is compressed into cylindrical pellets with diameters of 6–8 mm.
Cooling: Post-pelletizing, hot pellets are cooled in counterflow coolers to avoid deformation and ensure proper storage stability.
Sieving and Screening: Sieving machines remove fines and undersized pellets, which are recycled into the production process.
Packaging and Storage: Finished pellets are packaged in 25kg or 50kg bags, then stored in warehouses for domestic distribution or export.
