Organic Fertilizer
(Eco Compost)
We produce organic fertilizer using 100% domestically sourced biomass (unutilized organic materials) through traditional microbial fermentation.
Recycled through natural fermentation technologies, unutilized organic resources—such as sewage sludge, food factory residues, and rice bran—that were previously destined for landfilling or incineration.
With one of the highest production capacities in Japan (approximately 1,000 tons per month) and robust quality control systems,
our fertilizers are used not only in agriculture and horticulture, but also for maintaining urban green spaces and supporting large-scale land reclamation and greening projects.
Recognized as a soil conditioner with proven fertilizing effects, our product has been certified under the “Construction Technology Review and Certification Program” by the Organization for Landscape and Urban Green Infrastructure.
Its high quality and advanced technology have been officially acknowledged.
