Abstract

This work consists in studying the anaerobic fermentation, applied to the avicolous biomass,
established on the level of the industrial digester of Sousse Hammam, Tunisia.
The present study was interested towards:
- The qualitative productivity of produced biogas (gas composition, calorific value).
- The partial substitution of the forestry compost (FC) by the avicolous methacompost refined in its
two states (exits of the decanter and of digester) according to the same ratio of 20%. It is a question
of following the germination and the growth of the seedlings of Acacia cyanophylla installed on the
prepared substrates.
The synthesis of the principal results is the following one:
- The value of the energy produced and of the purification of the biogas produced.
- The incorporation of the avicolous methacompost has a remarkable positive effect on germination,
and consequently, on the growth of the seedlings of Acacia cyanophylla.
