Biomass Fuels We Handle

Biomass fuel is a renewable energy source derived from biological materials such as wood, branches, leaves, etc. It is a "carbon-neutral" fuel because the CO₂ absorption through photosynthesis during the growth of the raw materials offsets the CO₂ emissions during combustion, resulting in no net change in atmospheric CO₂ levels. Furthermore, utilizing agricultural residues and unused wood materials helps reduce waste.

PKS (Palm Kernel Shell) refers to the shell of the oil palm, an agricultural residue generated during the palm oil production process. Due to its low moisture content and high calorific value, it is utilized as a biomass fuel. To demonstrate the assurance of sustainability (legality) from the point of fuel origin (oil extraction mill) onwards, erex Co., Ltd. and its power generation subsidiaries (erex New Energy Saiki Co., Ltd., Buzen New Energy G.K., Okinawa Uruma New Energy Co., Ltd., and Ofunato Power Inc.) have obtained GGL (Green Gold Label) third-party certification. The GGL third-party certification includes the following requirements (a) through (d), and each company that has obtained GGL certification is committed to fulfilling each of these requirements.

Wood pellets are produced by compressing and solidifying waste wood, such as thinning residues and wood scraps generated during lumber processing. erex Group handles only wood with proven sustainability (legality), exercising due diligence and verification at every stage following the point of origin. Companies within the supply chain obtain third-party certifications such as PEFC (Programme for the Endorsement of Forest Certification) and FSC® (Forest Stewardship Council®) in accordance with Forestry Agency guidelines. Regarding FSC certification specifically, we source materials sustainably by utilizing raw materials from properly managed FSC-certified forests, recycled resources, and other controlled sources.
