About
Sun Metalon is an industrial hard-tech company pioneering zero-CO2 on-site metal recycling technology. Their flagship product, the Venus-L6, transforms contaminated metal waste — including swarf, sludge, chips, and turnings — into clean, high-value metal briquettes using a six-furnace heating process that produces zero CO2 emissions. Up to 20% of metal is wasted in manufacturing; Sun Metalon's technology recaptures that waste on-site, eliminating the need for third-party vendors or off-site storage. Melt yields exceed 90% even with fine polishing sludge from automotive and heavy-equipment industries. The company serves foundries, machine shops, and manufacturers seeking to reduce material costs, stabilize metal supply chains, and eliminate landfill disposal of metal scrap.
