04 — Company
Shandong Fengming Huanyu
Environmental Protection Co., Ltd.
Founded in 2021 in the Weihai Economic & Technological Development Zone. An R&D-led manufacturer working on oil and water purification — and on the question of how much of a barrel of oil really has to be thrown away.
Weihai Economic &
Technological Development Zone
Shandong, China
The company develops multi-purpose nano-sieving purification equipment — 50 nm and 100 nm grades, thirty-plus products across seven families. The applications run from steel and petrochemical to lithium battery production, water treatment and used-oil regeneration.
More than 10 % of turnover and headcount go into research. The technical team is led by foreign academician-level experts and established domestic specialists, working with Harbin Institute of Technology (Weihai), Shandong University (Weihai), Jilin University Bionics Institute and four further institutions. Two national and three provincial research projects are under way; the patent portfolio stands at more than forty.
Customers include PetroChina, Sinopec, Ansteel, HBIS, Linglong Tire, Triangle Tire and Lunan Chemical. We are open to agents and distributors who want to work on this rather than on a catalogue.

CompanyStandards and awards.
Some of these were earned before the company existed, through the predecessor's research work.
Standard
Contributing author of CJ/T 170-2018, Ultrafiltration water treatment equipment — the industry standard for the equipment class.
National
National High-Tech Enterprise · National Technology-based SME · Listed in the National Catalogue of Encouraged Major Environmental Technology and Equipment.
Provincial
Shandong “Specialised & Innovative” SME · Shandong first-set (major) technical product · Excellent Low Carbon Star.
Innovation
Shandong Circular Economy Innovation Science & Technology Major Achievement Award · Shandong Standardisation pilot enterprise.
People
One national-level talent and one provincial leading talent on staff, with one PhD, three master’s graduates and seven senior technical staff.
Research
Two national projects (new membrane materials, oil-sludge treatment) and three provincial projects under way.
Three sentences we actually mean.
Objective
Open the era of zero waste oil in industry. Not reduce it — remove it. Every machine we build is measured against how much oil it keeps in service rather than how much it processes.
Philosophy
Finite resources, endless circulation. A barrel of oil is a fixed quantity with an almost unlimited number of useful lives, if the equipment is good enough.
Vision
To become a supplier of oil purification equipment and service recognised at home and abroad — known for the standard, not the brochure.
Service
Professional, standard and modular solutions, with a technical team that answers within twenty-four hours. The after-sales conversation matters as much as the quotation.
