Our Technology

Doosan Lentjes offers proprietary environmental technologies for thermal waste and sewage sludge treatment and energy recovery. Our areas of expertise include the combustion of renewable fuels such as waste, sewage sludge and biomass, heat recovery systems and flue gas cleaning equipment. We deliver flexible solutions for long-term waste disposal security and climate-friendly steam and power generation.

Our Values & Benefits

  • Indispensable technologies
    We are proud that our proprietary technologies make an indispensable contribution to the reliable disposal of waste and sewage sludge. Because thermal treatment is the solution of choice for treating residual waste and sewage sludge in a resource-saving way according to the principles of a circular economy. This gives our products a perspective for many decades and you a job with a future.
  • From engineering to construction
    We supply partial and complete plants for the thermal treatment of waste and sewage sludge from a single source. With proprietary technologies for incineration, steam generation and flue gas cleaning, we offer solutions along the entire process chains. So, in your daily work you are always involved in the big picture and have the opportunity to experience the fascination of plant engineering!
  • Free space & personal responsibility
    We believe that highly qualified people need room for manoeuvre and freedom to develop their full potential. That is why you enjoy freedom of choice and a high degree of personal responsibility with us. Because you are the experts in your field and know best how to bring your projects forward.
  • Internationality & variety – every day
    We are proud to be part of a global group of companies. This gives us the security and strength we need to realise complex large-scale international projects. Every contract is unique and you will benefit from a varied working day where you can always learn something new. No day is like the other and our routine is called variety.
  • Private & professional life in balance
    We aim to help you achieve a good work-life balance – something that is also of particular concern to our works council! You can therefore look forward to flexible working hours with flexitime and a culture of mobile working, where you can work from home 40% a week in consultation with your supervisor. 30 days of annual leave are a standard at our company; in addition, you can expect up to four bridging days off per year. Overtime can be compensated for example with free time.
  • Together at eye level
    We aim to be successful together – regardless of title or position. It is important to us to discuss with each other at eye level and to support good ideas. Our managers see themselves not only as your superiors, but also as your colleagues. We are convinced that this approach promotes creativity and cohesion at all levels.
  • Lentjes Family
    We always give new colleagues a warm welcome and offer support wherever necessary. But even beyond onboarding, we are proud to say that you will be working with people you can really rely on and trust. From time to time, we also like to leave the daily work routine behind us to celebrate with our colleagues over cool drinks and a delicious buffet.
  • Cultural diversity
    We are convinced that diversity is always an enrichment and that diversity positively influences success. Therefore, our company is characterised by cultural diversity and we are proud of that! We have colleagues from many different countries on board and live internationality not only in our projects.
  • Bicycle leasing
    We encourage our employees to be active and therefore offer the possibility of leasing a bicycle (JobRad), which can of course be used privately. And there is a wide choice: whether mountain bike, Dutch bike or e-bike – almost any bike can become a JobRad. But that is not all: you can also lease additional bicycles for up to three family members.
  • Additional services for special private events
    We celebrate extraordinary days in your life with you: If you tie the knot, for example, you can look forward to two additional days off and a small allowance to start your life together. If you are already celebrating your silver wedding anniversary, we will congratulate you with one additional day off. Is your family growing? What a happy occasion to present you with a small gift and to give you two extra days off!
  • Modern and air-conditioned working environment
    We believe that a well-equipped working environment is elementary. Therefore, you can expect bright and friendly offices with air conditioning and an ergonomically equipped workplace.
  • Feel-good lounges
    We believe that where work is done on complex projects and technologies, there must also be room for creative refuelling and personal exchange. Our cosy lounges therefore invite you to chat with colleagues over a cup of hot tea or a glass of latte macchiato or to have lunch together.
  • Gastronomic offer in the headquarter
    We are pleased to offer you daily breakfast and lunch, freshly prepared in our canteen at the Ratingen site. In addition to meat dishes, our canteen always offers a vegetarian main course and fresh regional salads as well as sweet dessert options. In summer, we also like to meet in our beautiful inner courtyard with fountain to spend our lunch break together in the sun.
  • Free parking spaces
    We strive to make it easy for you to get to work in the morning without having to search for a parking space. Whether you use the car or the bicycle – you will find a variety of free parking options in the outdoor or in the underground car park.
