Tromso Co., Ltd. operates two main businesses: “Protecting Greenery” and “Nurturing Greenery.” Guided by a philosophy of addressing environmental and social challenges, we recycle rice husks and other agricultural residues into biochar and solid fuels, turning waste into resources. Applied to farmland, biochar promotes CO₂ sequestration, decarbonization, and carbon credit creation while improving soil health, reducing costs, and increasing farmers’ incomes. It enhances water retention, pH balance, nitrogen efficiency, and lowers contamination, proving valuable in drylands and acidic soils. As carbon credit systems expand globally, Tromso develops schemes that generate credits and return revenues to farmers, enabling sustainable, inclusive growth. Beyond machinery, we provide one-stop biochar services from farm support to carbon credit generation. We also manufacture rice husk solid fuel equipment, adopted in Japan and abroad, especially Africa, promoting resource circulation and carbon-neutral energy use.
