At Zenten, we have taken up the challenge of United Nations as our own. A challenge to consolidate a set of global objectives to eradicate poverty, protect the planet and ensure prosperity for all as part of a new sustainable development agenda. Each objective has specific goals that must be achieved in the next 15 years.


February 2022: Pay equity

A few months ago ZENTEN drew up an equality plan. After a pay audit it was found, among other things, that there are no wage inequalities.

January 2022: Donation to the FOOD BANK OF GIPUZKOA

As in 2021 we were not able to enjoy the summer and Christmas meals that all the staff celebrate every year, all the workers decided to donate this money to the GIPUZKOA FOOD BANK. This is our small contribution to those who really help others.

October 2021: Medical check-up

Once again this year, Zenten offers its employees the opportunity to undergo a medical check-up at the company’s expense.
Regular check-ups are one of the most effective ways to prevent many health problems.

July 2021: Clothing collection

Collection of clothes for the community of Quinchuqui Bajo, in Ecuador. This is the home town of a colleague.
In addition to helping those in need, we give a second life to our clothes.

April 2021: Keep active

For the next two quarters, the company will reward employees who come to work by bike or on foot. In this way we help to fight against sedentary lifestyles and encourage an active and healthy lifestyle.

March 2021: Deusto University

ZENTEN participates in the subject Entrepreneurship at the University of Deusto, presenting a case study and proposing a Challenge to the students. We like to collaborate with the educational community in our region.


In 2020 it was not possible to hold the company’s summer and Christmas meals. ZENTEN decided to donate the money for these celebrations.
Among all employees we have chosen the association NAGUSILAN as the recipient.

Big changes can be brought about by small, united actions.
Posters with information about small actions on food have been put up around the company to encourage our employees to lead a healthier life. We seek to raise employees’ awareness of food issues.

The course “Conversational Competences” is given to the employees in the offices.

The company tries to find the best courses adapted to the existing training needs. This course is very well received by the employees, who value it as “very useful” for their daily work.

Funds are collected among the workers to send to Quinchuqui Bajo (Ecuador) to help elderly people who are suffering the effects of the COVID19 pandemic in that community, where a colleague is from.

Testing fixtures and machining tools that are no longer suitable for our production are handed over to local training centres. They can use them for the training of their students.
We give a second life to our material and also help to train young people in our area.

Because there is no planet B, and it is everyone’s job to take care of it, the company proposes small actions to its employees that everyone can do in their daily lives, and contribute to taking care of the earth.

Together with local training centres, we develop internship programmes for young students. In this way we contribute to the education of young people in our region.

A group of ZENTEN workers voluntarily collected plastic and waste on the beach of Hondarribia. Having your environment clean and cared for is the first step in taking care of the planet.
