We are Environmental Problem Solvers！

That is not just a tagline — it is our reason for being. When you have a problem — wastewater that won't meet discharge standards, exhaust gases that fail compliance, sludge that costs too much to dispose, or chemical products that don't achieve the required purity — we don't just hand you a report and walk away. We design, build, deliver, and guarantee a solution that works.

Founded in Qingdao in 2016, Refine is an integrated environmental engineering company combining process design, equipment manufacturing, automation integration, and construction under one roof. With a compact but elite team of 35 professionals — over 90% of whom are technical specialists — we achieve what larger, less focused organizations cannot: deep expertise applied with agility and precision to your toughest challenges.

We are not a consulting firm that only produces drawings, nor an equipment vendor that only ships boxes. We are a problem-solving partner that takes full ownership of your environmental challenge — from first diagnosis through to commissioned operation and lifelong support.
