Cambi started as a development company called ”Kambi” in 1989, named after the latin word ‘cambium’ which is the part of the tree where growth takes place. The company was founded by the forest owners association Glommen Skogeierforening, in Norway. The technology was initially used to develop a steam explosion process for the paper and pulp industry.


However, that original application for the pulp and paper industry evolved in the direction towards the wastewater treatment sector due to promising results in laboratory tests. In 1992 the company was sold to the Norwegian oil trading and distribution company, Petrol Holding, which was in the process of diversifying into new areas outside of oil trading.


At this time, the first letter in the name was changed, and Cambi was founded, initiating the commercialization and further technology development of Cambi leading to the development of the Cambi Thermal Hydrolysis Process (Cambi THP™), which has revolutionized the handling of sludge and organic waste around the world. The first full scale THP project was developed with HIAS and implemented at a plant for the City of Hamar in Norway in 1994.


Based on the documentation of the performance through the first years of operation at HIAS, Cambi established a cooperation with Thames Water in 1998 to build a CambiTHP installation at Chertsey Wastewater Treatment Plant in England. As part of this cooperation, a JV-company called Simon-Hartley Cambi was set up to sell and supply the CambiTHP in the UK and Ireland. Soon contracts were signed for wastewater treatment plants in Scotland (Aberdeen) and Ireland (Dublin). After these projects Cambi took over Thames Water’s shares in the JV Company and renamed it Cambi UK Ltd.


During the same period Cambi won additional projects in Norway and Denmark. Among these was the biowaste treatment plant in the city of Lillehammer, Norway, treating food waste from 15 municipalities.


In the early 2000’s the basis was set for further international expansion and new contracts were obtained for plants in Belgium (Brussels), Poland and Australia.

Since then, Cambi has seen tremendous growth and acceptance of the CambiTHP™with now more than 50 plants either operational or under construction globally. For more information, please see our References.


Today Cambi is truly a global company, privately held, with more than 125 employees and locations in 9 countries and with a strong network of partners. Through its plants in operation or under construction in 21 different countries, Cambi serves more than 53 million people around the globe.
