Rheological properties of thermally treated and digested sludge

Rossano-Becerril, Sergio; Sleutels, Tom; Krooneman, Janneke (Bioconversion And Fermentation Technology); Euverink, Gerrit Jan Willem

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 …

ALACEN: A Holistic Herbaceous Biomass Fractionation Process Attaining a Xylose-Rich Stream for Direct Microbial Conversion to Bioplastics

Bertran Llorens, Salvador; Zhou, Wen; A. Palazzolo, Martin; Colpa, Dana; Euverink, Gert Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology); Deuss, Peter

Lignocellulose biorefining is a promising technologyfor the sustainable production of chemicals and biopolymers.Usually, when one component is focused on, the chemical natureand yield of the others are compromised. Thus, one of thebottlenecks in biomass biorefining is harnessing the maximumvalue from …

Conversion of a Xylose-rich Stream from Biomass-biorefining into Polyhydroxyalkanoate (PHA) by Schlegelella thermodepolymerans

Krooneman, Janneke (Bioconversion And Fermentation Technology); Bertran Llorens, Salvador; Zhou, Wen; Palazzolo, Martin A.; Colpa, Dana; Euverink, Gerrit Jan Willem; Deuss, Peter

The transition to a biobased economy necessitates utilizing renewable resources as a sustainable alternative to traditional fossil fuels. Bioconversion is a way to produce many green chemicals from renewables, e.g., biopolymers like PHAs. However, fermentation and bioconversion processes mostly rely …

Polyhydroxyalkanoates (PHAs) synthesis and degradation by microbes and applications towards a circular economy

Zhou, Wen; Bergsma, Simon; Colpa, Dana Irene; Euverink, Gert-Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology)

Overusing non-degradable plastics causes a series of environmental issues, inferring a switch to biodegradable plastics. Polyhydroxyalkanoates (PHAs) are promising biodegradable plastics that can be produced by many microbes using various substrates from waste feedstock. However, the cost of PHAs production …

Insight into polyhydroxyalkanoate (PHA) production from xylose and extracellular PHA degradation by a thermophilic Schlegelella thermodepolymerans

Zhou, Wen; Colpa, Dana; Permentier, Hjalmar; Offringa, Ruben Ate; Rohrbach, Leon; Euverink, Gert Jan Willem; Krooneman, Janneke (Bioconversion And Fermentation Technology)

Accumulation of non-degradable plastic waste in the environment might be prevented by the use of biodegradable polyhydroxyalkanoate (PHA). In this study, the thermophile Schlegelella thermodepolymerans produced up to 80 wt% PHA based on dry cell mass. The largest PHA granules were found in the cells …

Hanze Impact Podcast

Krooneman, Janneke (Bioconversie En Fermentatietechnologie); Heeres, André (Biobased Chemistry & Refinery)

Veel van de grondstoffen die we gebruiken voor de miljoenen producten die we produceren zijn niet duurzaam. Ze zijn eindig, fossiel en zeer vervuilend. Daarom zijn er nieuwe duurzame alternatieven nodig die we dagelijks kunnen inzetten bij de productie én na gebruik kunnen terugbrengen in een kringloop …
