Environmental protection at Aurubis Buffalo
Aurubis Buffalo, located in the state of New York, is about a half-hour away from Niagara Falls by car. Copper products have been fabricated here since 1906.
The completely integrated plant with approximately 580 employees includes a copper and brass foundry, a hot rolling mill and cold rolling mills, a number of annealing furnaces, and a number of longitudinal slitting machines to produce strips with a variety of copper alloys, for example for connectors, telecommunications, and electrical applications. In 2003, the plant became the first rolling mill for copper alloys in North America to earn TS 16949 certification, a quality management certificate based on ISO 9001. The investment program to modernize the plant is continuously updated.
Aurubis Buffalo operates environmental protection facilities in order to minimize emissions and to protect nature. All foundry off-gases pass through control devices (bag houses) and pass through dedicated filters prior to entering the atmosphere. Resulting filter dust that accumulates in the process is collected and subsequently sold to a third party as a substitute to mining raw zinc. The acidic rinse water from the copper/alloy cleaning operation is neutralized and treated in the company’s on-site treatment plant, which has significate capital investment in upgrades and improvement during recent years. The filter cake produced in the waste treatment plant still contains valuable metals and is therefore sent off for metal recovery. Ninety percent (90%) of the electricity consumption is obtained from a renewable power source, the Niagara Falls hydroelectrical generation plant. The New York State Department of Environmental Conservation (NYSDEC) identified environmental deficiencies at the Aurubis site in Buffalo, USA, and initiated legal proceedings in 2018. The deficiencies were related to the handling of hazardous substances and wastewater treatment.
To remedy these issues, the site developed an action plan that includes over 16 individual measures which have been implemented. With this regard, over 1.5 million US dollars, have been invested in technical upgrades at the site. Additionally, the number of Environmental management personnel have been increased and the organizational structures have been modified. Also, close monitoring with the help of external consultants is in place and should contribute to further risk minimization.
The introduction of an environmental management system in accordance with ISO 14001 was successfully implemented in 2022.
The Aurubis Buffalo site has been working jointly with the environmental team to increase education and awareness of chemical exposure; handling chemicals; managing hazardous & non-hazardous waste; process improvements to reduce waste generation; and environmental compliance requirement. Aurubis Buffalo ensures that the plant is compliant with federal and state regulatory requirements and laws.
We are continually raising awareness of new and changing environmental regulations through an education program that all employees participate in, which includes executive management and hourly workers to ensure all employees at Aurubis Buffalo are aware of federal and state regulatory systems.
Beyond the central environmental targets, additional activities were carried out for the benefit of the employees and the environment during the reporting period. For example:
- Continually re-evaluating the plant and processes waste reduction for potential opportunities
- Upgrades in the Aurubis Wastewater treatment plant have included:
- Sludge Press and Pump Rebuild
- Clarifier rebuilds
- Programmable Logic Controller (PLC) upgrade
- Upgraded Caustic Pumps
- Enhanced Instrumentation
- New sand filter
- Expanded containment area for acid storage
- New building to house sand filter and containment area
- New electrical control system and motor control center.
