Lipid-containing wastewaters, such as those arising from dairy processing, are frequently discharged at temperatures ≤ 20°C. Their valorization at low ambient temperatures offers opportunities to expand the application of high-rate anaerobic waste

Abstract Density dependence, population regulation, and variability in population size are fundamental population processes, the manifestation and interrelationships of which are affected by environmental variability. However, there are surprisingly

Ex-situ biological hydrogen methanation in trickle bed reactors : Integration into biogas production facilities

Autor: Donya Kamravamanesh, Johanna M. Rinta Kanto, Harri Ali-Loytty, Antti Myllärinen, Mikko Saalasti, Jukka Rintala, Marika Kokko

Biological hydrogen methanation (BHM) is a biocatalytic process for biogas upgrading. Integrating ex-situ BHM processes into biogas facilities has the advantage of using inoculum, CO2, and nutrients directly from anaerobic digestion (AD) processes to

Urban living lab (ULL) experiments are expected to create grounds for circular city transitions but their temporal dynamics remain understudied. This study investigates the linkages of a particular sanitation experiment to a long-term urban developme

Hydrothermal carbonization of pulp and paper industry wastewater treatment sludges - characterization and potential use of hydrochars and filtrates

Autor: Anna Hämäläinen, Marika Kokko, Viljami Kinnunen, Tuomo Hilli, Jukka Rintala

The pulp and paper industry's mixed sludge represents waste streams with few other means of disposal than incineration. Hydrothermal carbonization (HTC) could be advantageous for the sludge refinement into value-added products, thus complementing the
