Biochemical Methane Potential of Swine Slaughter Waste, Swine Slurry, and Its Codigestion Effect

The codigestion of slaughter waste with animal manure can improve its methane yield, and digestion parameters; however, limited studies are available for the effectiveness of anaerobic codigestion using swine slaughter waste (SSW) and swine slurry (SS). Hence, this study was conducted to determine t...

Hence, this study was conducted to determine the characteristics of SSW and the effect of anaerobic codigestion with (SS) and explored the potential of CH<sub>4</sub> production (<i>M</i><sub>max</sub>), the lag phase period (λ), and effective digestion time (<i>T</i><sub>eff</sub>). SSW contains fat and protein contents of 54% and 30% dry weight within 18.2% of solid matters, whereas SS showed only 6% and 28% within 4.1% of solid matters, respectively. During sole anaerobic digestion, SSW produced a high <i>M</i><sub>max</sub> (711 Nml CH<sub>4</sub>/g VS<sub>added</sub>) but had a long duration λ (~9 days); whereas SS produced a low <i>M</i><sub>max</sub> (516 Nml CH<sub>4</sub>/g VS<sub>added</sub>) but had a shorter duration λ (1 day). Codigestion increased the <i>M</i><sub>max</sub> from 22–84% with no significant <i>T</i><sub>eff</sub> compared to sole SS digestion. However, the low <i>M</i><sub>max</sub> of SS and high M<sub>max</sub> of SSW, resulted in a 7–32% decrease in <i>M</i><sub>max</sub> at codigestion compared to SSW sole digestion. Codigestion improved the digestion efficiency as it reduced λ (3.3–8.5 days shorter) and <i>T</i><sub>eff</sub> (6.5–9.1 days faster) compared to SSW sole digestion. The substrate-to-inoculum ratio of 0.5 was better than 1; the volatile solid and micronutrient availability may be attributed to improved digestion.
