With high regard to environment protection, VIIYONG keeps an eye to updates of hazardous substances directive and regulations globally.
Start from product and process design, we keep in mind the idea of environment, and employs environment friendly material and processes.
VIIYONG has got certificate QC080000 and comply with RoHS and REACH.
VIIYONG implements the principle of "clean production, standard discharge and total volume control" stipulated by government, and strictly implements the system to build waste water and waste gas treatment facilities, and regularly entrusts a third party to conduct monitoring.
With advanced equipments and technology in water pollution prevention and control, VIIYONG Technology has established the use of "filtration + ion exchange" method for wastewater which contains nickel after electroplating, and reuse the water into production through "biochemical + filtration" method, to achieve zero discharge of electroplating wastewater.
