Innovative and passionate, we have been setting new standards in the development and construction of plants for the lime industry - for more than 60 years.
Maerz Ofenbau AG was founded in Zurich as early as 1950. Initially active in the steel industry, the lime kilns industry soon became our core business.
Today, we are a dedicated team that focuses on the planning, development and construction of kilns and hydration plants for the lime industry. We support our customers worldwide in the construction of new lime plants as well as in the modernisation of older plants. From Japan to Peru or from Spitzbergen to Cape Town - today we are active in 70 countries and have built more than 700 plants.
Our service team will advise you on all questions concerning the process, operation of the plants, possible measures to increase efficiency or the supply of spare parts.
From the very beginning, the name "Maerz" has stood for cutting-edge technology and innovation in the lime industry. The PFR kiln, developed in the 1960s, is the most widely built kiln type in the world today and the most important in the lime industry due to its optimised energy consumption. The current Maerz EcoKiln® series sets new standards in the enrichment of CO2 in the kiln off-gases for further use or sequestration.
Together with our customers, we are always working on optimising and increasing the efficiency of our plants. For example, by developing firing systems that allow the use of a variety of fuels, or by adapting our kiln design to produce even better lime qualities.
We take responsibility for the future.
"CO2 emissions are the biggest challenge for the lime industry today. We are taking on this challenge and developing future-proof kilns."
