  SepPure engineers hollow‑fiber polymer nanofilters whose surfaces are tuned at the nanometer scale to allow target molecules through while blocking others, enabling membrane‑based separations in chemically harsh environments. Its membranes are designed for durability under strong solvents, high temperature, and high pressure, and the company claims it can pack roughly five times more membrane into a standard filter housing than incumbents. By shrinking the scale of downstream distillation and cutting reliance on fuel‑based heating, SepPure estimates dramatic cost savings—for example reducing the cost to produce 100,000 tons of oil annually from about $7.5 million to $2.5 million. The fibers are also reusable at end of life for applications like flame‑retardant fabrics. SepPure sees broad applicability across industries that still rely on distillation and positions its product as more compact and faster than earlier chemical‑resistant membranes. The company plans to scale manufacturing and implement modules at customer sites as demand grows. SEPPURE is a Singapore-based startup focused on chemical separation technology. The company works on chemical separation technology, though the article does not detail product specifics. It announced a $2.55 million seed funding round. The round was backed by Silicon Valley-based venture capital firm and accelerator 500 Startups.
