AB  - Comparative analysis of the kinetic models was
done by evaluation of the bio-kinetics constants of the
abattoir waste based on some selected existing models;
Monod, Logistics, Chen amd Hashimoto, Contois and
Teissier. A 10 L locally fabricated Biodigester was used
in this research with samples taken on a weekly basis over
a period of 64 days and analyzed for COD, TSS, VSS, pH
using standard methods (ASTM). The COD/VSS time
series data was fitted into the five microbial growth
kinetic models using non-linear regression analysis with
MATLAB 7.9. The data fitting also led to the
determination of these model’s biokinetic parameters and
their 95% confidence intervals. The data fitted well into
all the models with corellation coefficients R<sup>2</sup>>0.9 for all
the models with Monod&#146;s Model having the highest R<sup>2</sup> of
0.979. The biogas produced has a high content of
methane, 72.73% which is greater than the minimum
(>60% mol.) quality requirement for used in internal
combustion gas engines.
