“…Besides protein and lipid-rich substrates, some other biomass with a high degree of lignocellulose are used as a substrate for the production of biogas. Although this class of biomass is usually difficult to degrade because of their heterogeneous structure, recalcitrant nature and low accessibility by enzymes (carbohydrate polymers) [46][47][48]. Different pretreatment mechanisms are adopted in breaking down the heterogeneous matrix, increasing the surface area and porosity of the lignocellulose biomass for enhanced biogas production.…”

Anaerobic digestion is an efficient technology for a sustainable conversion of various organic wastes such as animal manure, municipal solid waste, agricultural residues and industrial waste into biogas. This technology offers a unique set of benefits, some of which include a good waste management technique, enhancement in the ecology of rural areas, improvement in health through a decrease of pathogens and optimization of the energy consumption of communities. The biogas produced through anaerobic digestion varies in composition, but it consists mainly of carbon dioxide methane together with a low quantity of trace gases. The variation in biogas composition are dependent on some factors namely the substrate type being digested, pH, operating temperature, organic loading rate, hydraulic retention time and digester design. However, the type of substrate used is of greater interest due to the direct dependency of microorganism activities on the nutritional composition of the substrate. Therefore, the aim of this review study is to provide a detailed analysis of the various types of organic wastes that have been used as a substrate for the sustainable production of biogas. Biogas formation from various substrates reported in the literature were investigated, an analysis and characterization of these substrates provided the pro and cons associated with each substrate. The findings obtained showed that the methane yield for all animal manure varied from 157 to 500 mL/gVS with goat and pig manure superseding the other animal manure whereas lignocellulose biomass varied from 160 to 212 mL/gVS. In addition, organic municipal solid waste and industrial waste showed methane yield in the ranges of 143–516 mL/gVS and 25–429 mL/gVS respectively. These variations in methane yield are primarily attributed to the nutritional composition of the various substrates.

“…DC, EFB, OPA were collected from palm oil mill of Palm Pattana Southern Border Company Limited, Pattani, Thailand (6 • 48 56.6568" N, 101 • 9 12.3732" E). Loosen EFB fiber [3] discarded from consecutive mechanical pressing and shredding was collected for further use. The EFB used in this investigation had already pretreated by a kind of steam explosion during the FFB sterilization by holding 3 bar gauge steam correlated to around 145 • C for 90 minutes then sudden depressurization.…”

“…Directly massive using of EFB as solid fuel for boiler is still limited since high content of potassium that could potentially lead slagging and fouling problems during EFB combustion. High slagging and fouling indexes indicate obstruct effective heat transfer in boiler [3]. In order to create sustainable and cleaner society and to avoid consequently environmental problems, abundant EFB leftover could be potentially minimized by converting it into other useful products, such as biogas, bio-syngas, bio-oil, and bio-chemicals.…”

Oil palm empty fruit bunches (EFB) and palm oil decanter cake (DC) were used to investigate biogas production by using solid-state anaerobic co-digestion (SS-AcoD) with 15% total solid (TS) content. Solid state anaerobic digestion (SS-AD) using substrate to inoculum (S:I) ratio of 3:1, methane yields of 353.0 mL-CH4/g-VS and 101.5 mL-CH4/g-VS were respectively achieved from mono-digestion of EFB without oil palm ash (OPA) addition and of DC with 10% OPA addition under mesophilic conditions 35 °C. By adding 5% OPA to SS-AD using 3:1 S:I ratio under thermophilic conditions (55 °C), mono-digestion of EFB and DC provided methane yields of 365.0 and 160.3 mL-CH4/g-VS, respectively. Furthermore, SS-AcoD of EFB:DC at 1:1 mixing ratio (volatile solid, VS basis), corresponding to carbon to nitrogen (C:N) ratio of 32, gathering with S:I ratio of 3:1 and 5% ash addition, synergistic effect is observed together with similar methane yields of 414.4 and 399.3 mL-CH4/g-VS, achieved under 35 °C and 55 °C, respectively. According to first order kinetic analysis under synergistic condition, methane production rate from thermophilic operation is 5 times higher than that from mesophilic operation. Therefore, SS-AcoD could be potentially beneficial to generate biogas from EFB and DC.

“…However, it has disadvantages such as being nonrenewable and not environmentally friendly. Tan, et al [6] found that hydrothermal palm oil treatment could increase alkaline-surfactant-polymer (ASP) flooding up to 26.0%, but the oil content decreased from 4.91 %wt to 0.39 %wt. An alternative surfactant that can be used for EOR is methyl ester sulfonate (MES), a biosurfactant from renewable vegetable oil.…”
