With the continuous strengthening of environmental policies today, the requirements for environmental protection work in companies are also increasing. Under the attention of company leaders, the company has recently successfully passed ISO14001 environmental system certification, marking that the company has reached an international level in environmental management. Strengthening the company's own environmental management is an inescapable responsibility of the enterprise as a member of society. Since the implementation of the company's self certification audit work, all processes including certification training, internal system construction, document review, on-site audit, and third-party certification agency audit have been smoothly carried out, and have been fully recognized by the expert review team.
