“…This derivations support the 270 finding of Hills and Nakano [23] and Sharma et al, [24] who observed that a linear relationship 271 existed between the gas production rate and the inverse of the particle diameter. It therefore 272 implies that the morphology of biomass with respect to shape, density, and all the factors related 273 to density such as porosity, degree of polymerization, the degree of crystallinity and amorphous biomass.…”

25The hydrolytic step is usually considered the rate limiting step in the biological conversion of 26 ligno-cellulose material into biofuels. Current optimization approach attempts to understand the 27 mechanism of hydrolysis in order to boost biogas production. In this study, the development and 28 testing of a surface-based and a water-based-diffusion kinetic model for modeling biogas 29 production from cow manure was conducted at ambient conditions using total solid (TS) loading maximum initial water uptake rate (k 0 2 ) (1.86E-05 m 3 /kg/day) was observed at 9% (TS) with a 39 simultaneous minimization in the rate of fragmentation (0.13/day). For optimal production of 40 biofuels from ligno-cellulose material, appropriate quantity of C 1 -factor in cellulase, the degree 41 of crystallinity and particle size may be critical for efficient biomass conversion.

“…Methane yield increased by 23% when fibres were cut to 2 mm size and was 0.22 m 3 CH 4 /kg VS compared to 0.18 m 3 CH 4 /kg VS for untreated fibres [4]. As reported also by Hills and Nikano [21], working on tomato waste chopped to particle sizes in the range 1.3 -20 mm, biogas yield increase was inversely proportional to the average particle diameter. Similarly Angelidaki and Ahring [22] reported a potential increase in methane yield of 16% for macerated manure biofilters with particle sizes between 1 and 2 mm, as compared to the fibres of 5 mm particle size.…”

This Anaerobic Digestion of Sisal decortication residue (SDR) from sisal decorication unit at Hale biogas plant in Tanga (Tanzania) is presented. The study was done to address the challenges facing Katani limited at Hale biogas plant. This plant was built as pilot before building other biogas plants. These challenges were like high retention time of substrate which was SDR, low biogas productivity, high investment costs due to large tanks sizes and low plant availability. From the study, it was discovered that, when particle size was reduced biogas production increased, degradation of SDR also increased and no significant change in biogas composition. Increase in biogas yield of 30% and 129% were recorded for reduced SDR compared to raw size SDR digested at atmospheric condition and 40˚C respectivelly. SDR degradation measured in TS and VS removal efficiency, showed increase in degradation of about 5% for the reduced particle size compared to raw size particle. The study concluded that SDR was good raw material for biogas production when 90% of the particles reduced to less than 2 mm. To maximize production, digestion must be conducted at high temperature around 40˚C with constant monitoring and control of all parameters. This will increase plant availability by increasing efficiency and life span of the pumps and stirrers.

“…After removal from the farm, samples for analysis were kept at 4 o C to preserve the original characteristics of the substrates. The wheat samples used in the BMP test were milled to a particle size of 0.5-1.5 cm to ensure homogeneity and good inoculum-substrate transfer (Hills and Nakano, 1984).…”

The effect of growth stage at harvest and of storage practice on the biochemical methane potential (BMP) of winter wheat was investigated using batch-fed stirred mesophilic digesters. The wheat used was a single variety sown at the same time (autumn) and harvested at 3 different stages in its growth: medium milk (A); soft dough (B) and Caryopsis (C). Wheats (A and B) were ensiled whilst the later harvested material (C) with a higher dry matter content was treated by the alkalage process. The BMP values expressed on the basis of volatile solids (VS) were 0.360±0.030, 0.346±0.006 and 0.311±0.016 l CH 4 g -1 VS added for A, B and C respectively. A simple first order kinetic model gave only a poor fit to the experimental data but a close match was obtained using a modified first order pseudo-parallel model which explains the methane production curve on the basis of differences in biodegradability of the plant material.
