Bernard Lagrange (April 20, 1955) is an independent environmental researcher. He was born in Saint-Germain-en-Laye of Georges Lagrange, an Esperantist. Called up for military service in 1975, he was rebellious, and, being clandestine, he worked for the APRE (Press Agency for Ecological Rehabilitation) and the review "Pollution Non", both edited by Jean-Luc Burgunder in Montargis. It is in this context that Bernard will conduct a major investigation into the production of biomethane, that is to say methane produced by the anaerobic fermentation of organic materials (manure, slurry, etc.). This investigation will lead to the publication of a work published in 1979 by Edisud editions under the title "Biomethane" which remains a reference in this field. After having participated in the 80s and 90s in various ecological alternative projects in the Lot and in the Landes, he is currently engaged in a project around alternative energies in Loire-Atlantique.
Bibliography
* Biomethane, Edisud / alternative energies, collection "Soft Technologies", 1979. 2 volumes:
1. a credible alternative, ISBN 2-85744-040-5 1
This first volume on biomethane successively presents organic matter as a source of energy, integrated systems, the geopolitics of biomethane and bioconversions as appropriate technology.
2. principles. technical uses, ISBN 2-85744-041-3 2
This second volume on biomethane presents methanogenic fermentation, continuous digestion as a means of purification, batch digestion and the production of biomethane, gas and its applications, the use of digestion effluents.

If his date of birth is correct, he wrote his 2 books at 24 years old! Low hat!
Otherwise it is especially the TOME 2 which is interesting at the construction level (I have a copy).
