Stera’s Environmental Policy

We try to reduce the environmental impacts of our operations. We use modern equipment and operating models in our production and operation. We take environmental impacts into account when designing our products, manufacturing and operations. If we see room for improvement in our customers’ or suppliers’ products or operations, we are not afraid to bring it out.

 

The waste that is generated in our operation is recycled in the best possible way and we try to reduce the amount of the waste. The environmental impact of each unit are mapped annually and the environmental program is modified if necessary.

 

We strive in every effort to ensure that we meet the requirements and legislation of the authorities. The company’s management and staff are committed to environmental policy compliance as well as continuous improvement.

Stera's Conflict Minerals Policy

Metals such as tantalum, tin, tungsten, and gold are used in many industries for manufacturing. But some sources of these minerals are in the Democratic Republic of Congo (DRC) and adjoining countries, and their extraction may finance or benefit armed groups that are associated with human rights violations. That’s why these four metals are known as “conflict minerals”.

 

Stera Technologies is committed to having a socially responsible supply chain and will not condone any abuse of human rights.

 

Stera commits to:

 

  • Support the aims and objectives of the EU legislation on the supply of “conflict minerals”
  • Do not knowingly procure specified metals that originate from facilities in the “conflict region” that are not certified as “conflict free”

 

If we discover the use of these minerals produced in facilities that are considered to be “non-conflict free”, in any material, parts or components we procure, we will take actions to transition products that are “conflict free”.
