Crucial Information

This study provides the first overview in Colombia on energy recovery potential by anaerobic digestion (AD) and dark fermentation (DF) of three different residual biomasses: coffee mucilage (CFM), cocoa mucilage (CCM), and swine manure (SM). First, AD and DF models were developed based on the ADM1 model. Then, simulated biogas production yields were compared to experimental data to validate the models. The results of comparative simulations indicate that energy recovery potentials from biogas for the different Colombian departments range from 148 to 48,990 toe, according to the local production amounts of CFM, CCM, and SM in 2017. The study provides crucial information that can be used to assess the best design, operation mode, and locations of AD and DF plants in Colombia. The results indicate that biogas production performances and energy recovery yields improve by increasing CFM/SM and/or CCM/SM ratios of the feed, and by increasing organic load from 2 to 26 gCOD∙l−1.

Cost Treatment

The industrial swine production is characterized by generation of significant effluent amounts that require treatment. The most adopted practices by Brazilian swine farmers have been wastewater storage in lagoons and its subsequent use as a biofertilizer. Nutrient accumulation in soil and water creates the need for an effective management of these residues. The anaerobic digestion process is an important alternative and low-cost treatment for organic matter reduction. However, its efficiency is limited by the digester capacity of solid degradation, especially at low hydraulic retention times. Thus, the present study aimed to verify the behavior of an upflow anaerobic digester by increasing the organic loading rate. This was accomplished in three stages using, as a parameter, volatile solids at 0.5; 1.0 and 1.5 kgVS m-3 d-1, respectively. This digester model proved to be quite robust and effective in swine manure treatment, achieving high efficiency of volatile solid removal at all stages of the study (stage 1: 61.38%; stage 2: 55.18%; and stage 3: 43.18%). Biogas production was directly related to the increasing organic load, reaching 0.14, 0.85, and 0.86 Nm³ kgVS-1add., respectively, with no significant difference (p<0.05) of biogas methane concentration among the studied stages (73.7, 75.0, and 77.9%).

This article intends to promote the usage of potato peels as efficient substrate for the anaerobic digestion process for energy recovery and waste abatement. This study examined the performance of anaerobic digestion of potato peels in different inoculum-to-substrate ratios. In addition, the impact of combined treatment with cow manure and pretreatment of potato peels was examined. It was found that co-digestion of potato peel waste and cow manure yielded up to 237.4 mL CH4/g VSadded, whereas the maximum methane yield from the mono-digestion of potato peels was 217.8 mL CH4/g VSadded. Comparing the co-digestion to mono-digestion of potato peels, co-digestion in PPW/CM ratio of 60:40 increased the methane yield by 10%. In addition, grinding and acid hydrolysis applied to potato peels were positively effective in increasing the methane amount reaching 260.3 and 283.4 mL CH4/g VSadded respectively. Likewise, compared to untreated potato peels, pretreatment led to an elevation of the methane amount by 9% and 17% respectively and alleviated the kinetics of biogas production.

BIOGAS ENERGY AND FERTILIZING POTENTIAL FROM PAPER SLUDGE Paper sludge contains potential as energy and fertilizer due to the high amount of C, N and P. The aims of this study were to investigate resource recovery potential through biogas production from paper sludge only and with cow manure as co-substrate for 30-45 days in batch anaerobic digestion reactor. In addition, the fertilizer potential from digestate was also tested in Vetiveria zizanioides. Co-digestion with cow manure yielded higher methane gas up to 380 CH4/g VS due to a more optimum C/N ratio. Vetiver plants grown on digestate relatively showed the high growth performance after 4 weeks. The heavy metal accumulation from digestate was still in tolerable amount since the growth rate was not significantly different with the plant grown in fertilizer. Therefore, resource recovery technology can be an option to recover C, N and P in paper sludge to achieve sustainable waste management.  Keywords: ananerobic digestion; biogas;  fertilizer; paper sludge AbstrakLumpur dari Air Limbah industri kertas memiliki C, N dan P yang tinggi sehingga berpotensi menghasilkan energi dan menjadi pupuk, Penelitian ini bertujuan untuk meneliti pemulihan sumber daya (resource recovery) melalui produksi biogas dari lumpur kertas tanpa dan dengan ko-substrat kotoran sapi selama 30-45 hari dalam reaktor batch anaerobic digestion. Selanjutnya potensi pupuk dari digestat juga diuji dengan tumbuhan akar wangi (Vetiveria zizanioides). Setelah 45 hari, lumpur kertas dengan kotoran sapi menghasikan gas metana yang lebih besar, yaitu 380 CH4/g VS. Tanaman akar wangi yang ditanam dengan dengan digestat R2 tumbuh relatif tinggi setelah 4 minggu. Akumulasi logam berat juga masih dalam batas aman karena laju pertumbuhannya yang masih sebanding dengan tanaman yang diberi pupuk. Oleh karena itu, pemulihan sumber daya dapat diterapkan untuk memanfaatkan C, N dan P yang terkandung dalam lumpur kertas sebagai usaha pengelolaan limbah berkelanjutan.  Kata Kunci: biogas; digestasi anaerobik; lumpur kertas; pupuk

Influences of temperature (25–35 °C) and substrate particulate content (3.0–9.4 g total suspended solids (TSS)/L) on granular sludge bed anaerobic digestion (AD) were analyzed in lab-scale reactors using manure as a substrate and through modeling. Two particle levels were tested using raw (RF) and centrifuged (CF) swine manure slurries, fed into a 1.3-L lab-scale up-flow anaerobic sludge bed reactor (UASB) at temperatures of 25 °C and 35 °C. Biogas production increased with temperature in both high- and low-particle-content substrates; however, the temperature effect was stronger on high-particle-content substrate. RF and CF produced a comparable amount of biogas at 25 °C, suggesting that biogas at this temperature came mainly from the digestion of small particles and soluble components present in similar quantities in both substrates. At 35 °C, RF showed significantly higher biogas production than CF, which was attributed to increased (temperature-dependent) disintegration of larger solid particulates. Anaerobic Digestion Model No.1 (ADM1) based modeling was carried out by separating particulates into fast and slow disintegrating fractions and introducing temperature-dependent disintegration constants. Simulations gave a better fit for the experimental data than the conventional ADM1 model.

The possible exploitation of two-phase anaerobic digestion for swine manure was investigated in this study. One-phase and two-phase anaerobic digestion process were investigated in continuous stirred-tank reactor with hydraulic retention times 15 days (hydrolysis and acidification for 3 days and methanogenic12 days in two-phase). When the organic loading rates were equal to or less than 4 g VS/L day, the biogas yield and volumetric production of two processes were no significant difference. However, in the case of organic loading rates being equal to or higher than 5.0 g VS/L day, two-phase biogas yield and volumetric biogas production averaged 0.294 L CH4/g VS added and 2.218 L/L day, compared with one-phase averaged 0.255L CH4/g VS added and 2.168 L/L day, respectively. Significant advantages in saving cost of biogas project were indicated by the comparison of biogas production and COD degradation in the one-phase and two-phase processes.
