Through its subsidiary Natural Power International (NPI), PCA provides companies in the agro-industry with a resource management system that converts agricultural waste and by-products into usable energy.

NPl ranks among a small group of biogas project developers which have proven the reliability, durability and efficiency of its installations. With over 20 years of professional experience, NPI specializes in planning, design, construction, and operation of biogas plants using proprietary membrane technology for the agro-industrial sector. NPI’s highly efficient technology was utilized in the first large scale biogas CDM project in the Thai Palm Oil Sector (Chumporn Palm Oil Industries; Project ID: CDM 2148). In addition, NPI is currently commissioning the biggest biogas plant in Southeast  Asia running on Palm Oil Mill Effluent (120t FFB/h palm oil mill, 6MWe Power Output)

Benefits of NPI’s Biogas Solution:

• Higher rate of degradation of organic material than compared to other systems on the market, COD/BOD reduction above 95%Higher rate of biogas production)
  • Approximately Biogas production of 34m3/m3 POME (at 308 K), or at 30Nm3/m3 POME (at 273K)
  • For a palm oil mill of 60tFFB/hr, able to generate up to 2.5 MW of electricity
• Simple to operate, with lower operating and maintenance cost compared to other systems. Internal power consumption less than 3% of power output
• No corrosion issue on digesters
• Advanced sludge removal technology. Sludge removal is a Continuous and reliable process with no system shut-downs required.
• Underground digester offer excellent insulation properties, and ensures that biogas production is not affected by weather influence
• Robust & scalable system can handle fluctuations in feedstock quality and quantity
• Membrane cover offer bigger gas storage area and assured steady gas quality
• Cost-effectiveness of installation and maintenance (high value for money)
• Extended life span of digester system (min. 20 years)
