15 Apr 2025

 We are proud to welcome 1nergiek as the newest partner of Green Business Club (GBC) Netherlands! This versatile facilities company is committed to sustainability and wellbeing within the working environment, including in office complexes Atrium and Symphony Offices in Amsterdam Zuidas. We spoke with Managing Director Laetitia Simonis about their mission and sustainable initiatives.

What kind of company is 1nergiek and what do you stand for?

“1nergiek is a facilities partner that operates nationally in various sectors, such as business services, hotels, retail and healthcare. With more than 500 cleaning colleagues, we ensure a clean, healthy and safe working environment every day. But we go beyond cleaning alone; we focus on sustainability, innovation and the wellbeing of our employees,” Simonis says. “At 1nergiek, it is not just about a clean building, but also about creating a pleasant and inspiring working environment. We look beyond the usual cleaning services and actively think along about optimising workspaces. Sustainability and people-centered working form the core of our approach.”

How does 1nergiek contribute to making buildings more sustainable?

“We look at the entire chain and work with circular solutions. That means we not only use environmentally friendly cleaning products, but also focus on waste monitoring, data-driven cleaning and zero waste initiatives. In a large multi-tenant office building, for example, we introduced a waste monitoring system that reduced the amount of residual waste by forty percent in six months. These kinds of initiatives show that small changes can have a big impact.”

“In addition, we innovate through the use of microfiber technology, dosing systems and plastic-free cleaning materials. Our approach prevents waste and ensures that buildings are maintained not only cleanly, but also sustainably.”

What role do you play in multi-tenant buildings?

“Our role goes beyond cleaning alone. We create a healthy and inspiring working environment in which tenants, employees and visitors feel at home. We do this by facilitating waste separation, using circular cleaning solutions and raising awareness among building users. We believe that a clean working environment contributes not only to productivity, but also to people's wellbeing.”

“In addition, we work closely with building owners and facility managers to actually implement sustainable initiatives. This can range from smart energy management to more efficient waste separation systems, with tenants actively involved.”

You score highly on employee satisfaction. What is your secret?

“At 1nergiek, our employees come first. We invest in their wellbeing and development, which pays off in committed and satisfied teams. In our latest employee satisfaction survey, we scored an 8.3, well above the industry average. We even won the Integron Employee Experience Award for the third year in a row. This is due to the personal guidance, growth opportunities and safe working environment we offer. The low absenteeism rate – from 10% to 5.3% – shows that this works.”

“We support our team with training, ergonomic tools and growth opportunities. This not only creates satisfied employees, but also contributes to a higher quality of service.”

Concrete example: smart waste monitoring and behavioural change

“One of our most successful sustainability projects is the waste monitoring system we implemented in a large multi-tenant office building. By gaining detailed insight into waste flows, tenants were able to handle their waste more consciously,” Simonis explains.

“We set up strategically placed waste stations, used clear communication about proper separation and provided training to employees. As a result, the amount of residual waste decreased by 40% in just six months, while recycling rates increased. This resulted in cost savings for tenants, a circular impact on the building and a cleaner working environment.”

Future ambitions and further collaboration

“For the future, we are focusing on further digitalisation and robotisation, always with the aim of supporting our employees and taking sustainability to a higher level. Innovation serves people in our organisation, so that they can work more efficiently and enjoyably. This aligns perfectly with our ambition to work completely climate-neutral in the near future, including through the use of sustainable products and energy-saving technologies.”

What makes this partnership valuable for you?

“Sustainability is not a solo act, but a collective effort. At 1nergiek, we believe that real impact is created when organisations join forces. GBC Netherlands brings together companies that want to contribute to a sustainable future. We want to actively contribute by sharing knowledge, learning from other frontrunners and working together on concrete sustainable initiatives. Whether it is waste reduction, energy savings or a healthier working environment – we are happy to think along. This partnership offers the opportunity to take steps towards a more sustainable future together. We look forward to inspiring collaborations and great projects!”

Project manager Nina van den Berg is pleased with new partner 1nergiek; ‘Facilities companies play a key role in circular and sustainable business operations. Within Atrium and Symphony, 1nergiek is active as a cleaning partner for both the common areas and several tenants, including Hogan Lovells. There may be a role for 1nergiek in achieving tenants' zero waste objectives, starting with making waste data accessible at tenant level, something that is much in demand among GBC participants.’
