STERK is one such organization that strives for growth and innovation in a way that is good for people, society and the environment. How we do that, we gladly explain below.


A company operates in a socially responsible manner if it consciously focuses its activities on adding value to people, planet and profit, continually seeks a careful balance in this, is accountable for this in an active and transparent manner and maintains an open dialogue with its stakeholders about it.

Companies can even go a step further and focus on new market opportunities, growth and innovation with gains for people, society and the environment. Now and in the future.


One of our goals is to put people to work by creating employment opportunities. Hard work is well rewarded with us. We also offer our people opportunities for growth in the form of courses, training and even education.


Our way of working is aimed at allowing people to gain work experience in an accessible way. We offer guidance and support where necessary, with the aim of enabling as many people as possible to move on to a suitable, sustainable and, if possible, paid workplace at another company.


Our motto is making work through reuse. We achieve this by giving used items a second life. We dispose of all the used items we collect daily in a responsible manner by, first, seeing if something is still usable or sellable. As a result, we "save" up to 40% of all the goods we collect.
