On 18 August 2015, the Bulgarian Chamber for Mining and Geology held their annual miners' day.

During the event, EnviroChemie was honoured in the Environmental Protection category for its rainwater treatment project at Aurubis Bulgaria. At Aurubis' Bulgarian site, grade A copper in the form of marketable copper cathodes made from copper concentrates is produced.

The environmental protection prize was received by Dr. Maria Natcheva-Schwarz, EnviroChemie's Bulgarian country manager. EnviroChemie handled the planning, construction, assembly and commissioning of the environmentally-friendly plant technology that was made in Germany.

The energy-efficient wastewater treatment plant has a hydraulic capacity of up to 250 m³ per hour. The water, which is primarily contaminated with copper, but also with other heavy metals and arsenic is processed using an Envochem chemical-physical plant until it achieves direct discharger quality. It is then filtered and released directly into the watercourse of a mountain stream. As the mountain stream is used as a source of drinking water for residents in the region, very low discharge values must be respected. The plant technology runs on minimal operating costs and safely meets the required limit values for treated wastewater.
