Turning Waste into Value | Building Sustainable Futures
Rhino’s Silica Plastic Block (SPB) technology addresses one of the foundry industry’s toughest challenges—safe disposal of used sand and dust—by blending 30–50% foundry waste with 50–70% low-grade plastic to create strong, durable building products like pavers, blocks, and pots.
Developed through in-house R&D since 2017 and validated in collaboration with industry, SPB has proven its ability to repurpose waste at scale—for every 1 kg of plastic, up to 3 kg of used sand can be recycled.
