Briefly about NOAH

NOAH is one of Europe’s leading expertise centres for treating inorganic hazardous waste, polluted soil and sediments. The biggest waste quantities are treated in the plant on Langøya outside Holmestrand. NOAH also has offices and plants in other places in Norway, Sweden and Denmark.

Introduction

NOAH has approx. 70 employees and approx. 30 contractors. Carl Hartmann is the CEO. NOAH AS is owned 100% by Gjelsten Holding AS.

The main process in the treatment involves neutralising ferrous sulphuric acid. This process uses another waste product: fly ash from the incineration plant. Other heavy metal waste streams are also used in the neutralisation process, where the heavy metals are bound together and become non-hazardous. The result is ferrous plaster slurry. This is pumped down into the two craters on Langøya, which formed over a period of 100 years from limestone mining. Here the plaster forms a foundation that is part of the re-construction and recreation of Langøya as it was before limestone mining began.

NOAH receives hazardous waste and polluted mass from Norway and Scandinavia, as well as smaller amounts of waste from individual European countries. The treatment plant is robus and has a large capacity.

NOAH’s company is of major environmental significance as large amounts of substances that are harmful to the environment are removed from the natural cycle. Emissions from the process have very little effect on the environment. Other information about the company is available on other pages of this website.
