9. Conclusion
As we have tried to show in this document, methanization is a technology of the future for the treatment of effluents containing organic carbon (wastewater, sludge, waste). It is an optimized application of biological phenomena that enables a significant proportion of the energy contained in various organic molecules to be transformed into an easily recoverable form: biogas. It's a mature technology at the start of the 21st century, with the implementation of high-performance, stable processes that meet modern requirements in terms of occupying space, saving energy and reducing the production of excess sludge.
As a "high biological pre-treatment" technology for waste effluents, methanization appears to be the ideal preliminary treatment to aerobic technologies, enabling further progress in pollution purification, but with a significant reduction in energy costs...

Classification of Atex zones
European Directive 1999/92/EC of the European Parliament and of the Council of December 16, 1999, on minimum requirements for improving the safety and health protection of workers potentially at risk from explosive atmospheres (OJEC, January 28, 2000). This directive was transposed into French law by a decree published in the JORF (n° 303 of December...

Statistical and economic data
Given the difficulty of keeping up-to-date information on anaerobic references, you will find below economic data dating from 2002. Only industrial plants larger than 2 to 3 tons COD/day could be identified through published manufacturer data, or by taking into account plants known but not precisely referenced by the manufacturer, or in databases specific to each industry. However, these data show that the...
