At Tamoin, we understand Sustainability as a strategic commitment that permeates every aspect of our activity. From the definition of our corporate policies to the execution of field projects, we integrate sustainable practices that promote a balance between industrial development, environmental respect, and social well-being.
This commitment materializes through close collaboration with our stakeholders —employees, suppliers, and clients, among others— with whom we work side-by-side to foster responsible practices and continuously improve our Sustainability performance.
As part of GTM Grupo, Tamoin adopts the group’s Sustainability Model, a comprehensive framework covering six key areas: People and Working Conditions, Environment, Ethics and Compliance, Human Rights, Society, and Clients and Suppliers. This model allows us to effectively structure and direct our sustainable actions, ensuring compliance with the highest ethical and regulatory standards.
At Tamoin, we reaffirm our strategic commitment to legality, ethics, and integrity in all our operations. As an integral part of GTM Grupo’s Criminal Compliance Program, we adopt a zero-tolerance policy toward any criminal conduct.
This commitment extends to all our activities, regardless of whether they are carried out at our own centers or at our clients’ facilities. Our goal is to guarantee regulatory compliance at all levels and contexts of our activity.
The GTM Grupo Criminal Compliance Program establishes a solid regulatory framework, which includes a Code of Ethics that guides the professional and responsible behavior of everyone who is part of the organization.
Furthermore, we have an Online Ethics Reporting Channel: an essential tool for preventing and detecting criminal conduct or behavior contrary to internal regulations. Through this channel, both internal staff and third parties associated with Tamoin can report any irregular incident or conduct confidentially and/or anonymously.
At Tamoin, we work every day to provide industrial service engineering solutions with the highest standards of Safety, Health, Environment, and Quality.
Our commitment in these areas is not only a guarantee of compliance but also a key lever for building long-lasting relationships of trust with our clients and supporting them on their path toward efficiency and sustainability.
People’s safety is at the heart of our way of working.
At Tamoin, we promote a solid and active preventive culture based on continuous training, awareness at all levels, and the genuine involvement of all employees, both at our own facilities and those of our clients.
We are not satisfied with merely complying with regulations; we always strive to go further. We anticipate risks and foster safe, collaborative, and constantly evolving work environments.
Because prevention is not a formality, but a shared commitment and a collective responsibility. Therefore, we work side-by-side with our clients to implement the necessary measures that allow us to achieve a common goal: zero accidents.
Environmental sustainability is part of our strategic vision.
At Tamoin, we promote the continuous improvement of environmental performance, integrating sustainability criteria into all our processes and services, with a vision that goes beyond compliance and seeks to generate a lasting positive impact.
We address key aspects such as local pollution control, efficient water resource management, the circular economy and proper waste management, biodiversity protection, the fight against climate change, and the rational use of energy.
On this path, we align ourselves with our clients’ environmental objectives and work as allies to actively contribute to their achievement, combining capabilities and commitments toward a more sustainable industry.
Tamoin is synonymous with professionalism, reliability, and commitment.
Our long-standing experience in the industrial sector enables us to deliver services to high standards, combining proven methodologies, adaptability and an innovation-driven approach.
We work with a flexible and collaborative approach, adapting to the specific needs of each client. Their goals are also ours, and our team is focused on achieving their maximum satisfaction in every intervention, with a culture of continuous improvement as our driving force.
Our commitment to excellence is based on an Integrated Management System certified by an independent third party, in accordance with international standards:
|
ISO 9001:2015 (Quality) |
ISO 14001:2015 (Environment) |
ISO 45001:2018 (Occupational Health and Safety) |
Furthermore, we hold the necessary industrial authorizations for the provision of our services and the UNE-EN 1090 certification, which accredits the conformity of workshop production control for the execution of steel structures in accordance with European requirements.
