“…Compared with raw champost, oyster champost has a higher cellulose and hemicellulose content of 48.3% and a lower lignin content of only 9.4% (based on dry matter). Besides, the carbon/nitrogen ratio (C/N) of oyster champost was 32.6, which is in the suitable range for anaerobic digestion (Fang et al, 2020). Abundant cellulose and hemicellulose in the oyster champost were the important carbon and energy sources for growth and metabolism of anaerobic microorganisms, which lead to the high biodegradability and VFA production from oyster champost in control and unpretreated group (Fig.…”

White rot fungi using P. sajor-caju and T. versicolor was examined to pretreat raw champost (lignin-rich) and oyster champost (cellulose-rich) for enhancement of fermentative volatile fatty acid (VFA) production. Results showed that the efficiency of pretreatment and VFA production was influenced by the fungal strains and substrates. P. sajor-caju pretreatment showed preferential lignin degradation on raw champost and obtained the maximum VFA yield (203 ± 9 mg COD/g VS added), which increased by 60% and 74% compared to that of control and unpretreated champost, respectively. For cellulose-rich oyster champost, however, fungal pretreatment decreased VFA yield compared to unpretreated champost. Further mechanisms analysis demonstrated the two strains grow and secreted ligninolytic enzymes, which substantially influenced the characteristics of two champosts such as cellulose/lignin ratio and morphology in different extents. P. sajor-caju was highly efficient to lignin-rich champost on selectively degrading lignin and further enhancing digestibility such as VFA production.

“…The reason for improved biogas yield could be the improved C/N ratio of the substrate with the addition of grass. Co-digestion with organic substrates like Typha latifolia in comparison with mono-digestion offers better digestibility, better nutrient availability (Grosser et al, 2018), increased pH buffering capacity and dilution of toxic substances such as ammonia (Fang et al, 2020). The highest biogas yield was achieved with the mixture of SS, grass and rumen fluid (samples SGR1, SGR2; Fig.…”

“…The following analytical methods were used: SIST EN 16168:2013 for determining total nitrogen content, SIST EN ISO 11885:2009 for the total phosphorus content, SIST EN 13137:2002 for total carbon content and SIST EN 14346:2007 for the dry matter content. Anaerobic digestion depends on various operating parameters such as temperature, pH, system configuration, substrate composition and hydraulic retention time (Fang et al, 2020). In the following, the results obtained in mono-and co-digestion of sewage sludge (SS) and Typha latifolia grass are presented in regard to some of these operating parameters.…”

The 2 nd International Conference on Technologies & Business Models for Circular Economy (TBMCE) was devoted to presentations of circular economy concepts, technologies and methodologies that contribute to the shift of business entities and society as a whole to a more responsible, circular management of resources. In the framework of TBMCE 2019, we presented the Strategic Research and Innovative Partnership -Network for the Transition to Circular Economy (SRIP-CE) as a platform for establishing a successful long-term public-private partnership. The conference program included panel discussions, plenary and keynote sessions, oral and poster presentations on the following topics: Sustainable energy, Biomass and alternative raw materials, Circular business models, Secondary raw materials and functional materials, ICT in Circular Economy, Processes and technologies. TBMCE 2019 was organized by Faculty of Chemistry and Chemical Engineering, University of Maribor and held in Portorož, Slovenia at the Grand Hotel Bernardin from October 24th to October 25th, 2019. The event was under the patronage of Ministry of Economic Development and Technology.
