About METabolic EXplorer - www.metabolic-explorer.com

METabolic EXplorer is a biological chemistry company. Incorporated in 1999 it aims to help industrial firms cope with the forthcoming end of the oil age so that they can continue manufacturing but in a sustainable way.

Based on the tried and tested principle of industrial fermentation, METabolic EXplorer's solutions circumvent the problems posed by today's burdensome and expensive petrochemical processes via the use of a wide range of renewable, sustainable raw materials. By optimizing the metabolic yield of non-pathogenic bacteria in a contained, controlled environment, the company facilitates the production of chemical compounds used in a wide range of everyday goods (textile fibres, paints, solvents, plastics and animal feed).

METabolic EXplorer is currently focusing its alternative biological solutions on the production of five compounds that together have an estimated, annual, end-market value of €11 billion. The company's strategy will be implemented in two forms – either via own-account developments (i.e. manufacturing plants) in geographically strategic regions, or via limited exclusivity industrial partnerships in the shape of joint ventures.

METabolic EXplorer, based in Clermont-Ferrand, France, is listed on Euronext Paris (Euronext C, METEX) and is a component of the CAC Small index.
