“…The calibrated disintegration rate constant resulted equal to 0.823 d − 1 , a value higher than those suggested by ADM1 (0.5 d − 1 ). It is worth to note that a wide range of values of k dis exists in literature depending on the solid content of the treated biowaste. As an example, Feng et al .…”

“…The calibrated disintegration rate constant resulted equal to 0.823 d 21 , a value higher than those suggested by ADM1 (0.5 d 21 ). It is worth to note that a wide range of values of k dis exists in literature [9,12,30,31] depending on the solid content of the treated biowaste. As an example, Feng et al [30] found the very high value (10 times higher than those recommended in ADM1) of 4.5 d 21 for k dis when applied the ADM1 to the anaerobic digestion of blackwater, that is a liquid phase substrate.…”

Brewer's spent grain (BSG), the residual solid fraction of the final mash process of malting, is a main waste fraction of beer production, recently considered as possible substrate for biovalorization by anaerobic digestion (AD). In this article, the biomethanization of BSG was evaluated by performing biochemical methane potential (BPM) tests. The obtained specific methane production (SMP) was 0.284 LCH4·g-1COD. The process was modelled by implementing the Anaerobic Digestion Model No.1 (ADM1) into AQUASIM software with the focus on the disintegration and hydrolysis step. The calibrated disintegration rate for BSG was equal to 0.823 d-1 and the hydrolysis rate constants varied from 0.124 d-1 for lipids to 1.056 d-1 for proteins. The obtained results showed a good efficiency in treating BSG with anaerobic digestion. The practical conversion degree of the biowaste COD into methane was equal to 81.1%, a high value for a substrate with an elevated solid content. Moreover, the estimated values of disintegration and hydrolysis rates complied with the retention time values generally adopted in an anaerobic digestor

“…Experiments are either used to gain insight into indicators for the AD efficiency (Schievano, D'Imporzano, Orzi, & Adani, 2011) or are linked with mathematical models to provide necessary parameters for the calibration of AD simulation. In these, often modifications (Lübken, Wichern, Schlattmann, Gronauer, & Horn, 2007) or simplifications (Biernacki, Steinigeweg, Borchert, Uhlenhut, & Brehm, 2013;Weinrich & Nelles, 2015) of the anaerobic digestion model no. 1 (ADM1) are used.…”

A plant‐specific model approach to assess effects of repowering measures on existing biogas plants: The case of Baden‐Wuerttemberg

Up to the latest versions of the German renewable energy act (EEG), there had been a constant growth of new biogas plants (BGPs). After reaching a stagnation in the last years, today the focus has shifted to improving the existing BGPs. Assuming that most plants have not reached the technical end of life, the question arises on how an operation can be realized beyond the initial EEG support period of 20 years. In addition, new legal and economic conditions require the implementation of adjustments, that is, “repowering measures.” Based on a method review, a plant‐specific model approach is presented to assess repowering measures for a wide range of BGPs differing in capacity, substrate mixture and agricultural structures. The techno‐economic model includes different performance indicators like levelized cost of electricity (LCOE) and temporal aspects like technical progress. Using a data set for BGPs in the state of Baden‐Wuerttemberg (Germany), results are illustrated for the different model modules and three repowering scenarios of an extended operation period of ten years. The scenarios regard different options to meet the requirements of the current EEG, namely the flexibilization and restrictions on energy crops, in comparison with a reference case. While in repowering scenarios, the number of plants decreases between 54% and 69% and the overall power capacity changes between −48% and 13% until 2035. The results further show a reduction potential in the specific area demand and GHG emission up to 12% and 24%, respectively. Technical progress, additional revenues and capacity premiums are shown to be an important factor for efficient substrate utilization, low LCOE and thereby the enabling of an extended operation period. The scenario results indicate that the agricultural areas for energy crop cultivation and the amount of manure used in BGPs will be reduced considerably, inducing new chances and challenges in the future.

“…Biernacki et al [30] determined common hydrolyses kinetic constants for several substrates; cattle manure got value 0.236 d À1 . Hydrolysis equation applied in this study calculates hydrolysis rate constant k hyd as function of maximum hydrolyses rate, hydrolytic bacteria, substrate concentration and VFA concentration.…”
