GreenVector operates through Laputa, a Hong Kong-based manufacturer of sustainable construction materials. Laputa produces eco-friendly bricks and paving blocks using recycled glass, construction waste, and carbon capture utilization processes that sequester CO2 during production. Certain products are engineered to remove urban air pollutants. Construction firms use these products as substitutes for conventional materials to meet green building standards and emissions regulations. Laputa also generates secondary revenue by subleasing factory and office space to third parties. The company is currently transitioning its business model from selling through an affiliated distributor, TioStone Environmental, to a direct-to-customer sales approach to strengthen client ties and manage logistics. Its growth strategy includes expanding manufacturing capacity, developing next-generation low-carbon materials through university partnerships, and pursuing acquisitions in the precast concrete sector. The business faces high customer and supplier concentration, specifically regarding its reliance on TioStone and a limited group of raw material vendors for cement and aggregates.
