Understanding sludge rheology and optimizing equipment performance is crucial for energy efficiency in wastewater treatment plants (WWTPs). This study examined sludge rheology after thermal hydrolysis pretreatment (THP) at 60, 80, and 120 ◦C for 2 h, followed by anaerobic digestion (AD) at 37 ◦C for …

In a long-term project, together with Courage, we are investigating whether it is possible to determine volatile fatty acids, methane or acetone in the air blown from dairy cows. These substances are associated with health and digestion of the cow. We are working on a sensor together with tech partners …

Background Gastrointestinal symptoms are common during chemotherapy, but underlying disturbances in gut function and their impact on daily life are unclear. This study investigates gut function in a heterogenous group of cancer patients with gastrointestinal symptoms during chemotherapy and its relation …

High-pressure anaerobic digestion is an appealing concept since it can upgrade biogas directly within the reactor. However, the decline of pH caused by the dissolution of CO2 is the main barrier that prevents a good operating high-pressure anaerobic digestion process. Therefore, in this study, a high-pressure …

A bioaugmentation approach was used to enhance the performance of anaerobic digestion (AD) using cow manure (CM) as the substrate in a continuous system. To obtain the desirable microbial culture for bioaugmentation, a biochemical methane potential test (BMP) was used to evaluate three commonly used …

Many articles have been published on scale-down concepts as well as additive manufacturing techniques. However, information is scarce when miniaturization and 3D printing are applied in the fabrication of bioreactor systems. Therefore, garnering information for the interfaces between miniaturization …

Brain & Technology is about the relationship between mind and technology, so about brain and lifelong learning, and therefore about the extended mind. More generally, humanity uses technology to outsource brain processes (mind) to smart devices, just as we partially outsource our digestion to cooking …

This study evaluated the performance of anaerobic co-digestion of cow manure (CM) and sheep manure (SM) in both batch and continuous digesters at 37 °C. Synergistic effects of co-digesting CM and SM at varying volatile solids (VS) ratios (1:0, 0:1, 3:1, 1:1, 1:3) were observed in the batch experiment, …

Bioplastics are gaining interest as an alternative to fossil-based plastics. In addition, biodegradable bioplastics may yield biogas after their use, giving an additional benefit. However, the biodegradability time in international norms (35 days) far exceeds processing times in anaerobic digestion facilities …

The concept of green biorefinery is based on the processing of green biomass into range of innovative products. The basic idea is to use the green biomass in the most optimal way to produce energy and marketable products. Grass silage has versatile properties as raw material for green biorefinery with …
