Enhanced hot-liquid water pretreatment of biomass with recovery and valorization of side products

Jankovic, T.J. (author), Straathof, Adrie J.J. (author), Kiss, A.A. (author)

Lignocellulosic biomass potentially represents a great feedstock for biofuel production, but its’ pretreatment needs to be enhanced in order to make biorefineries competitive with fossil fuel based alternatives. One way to make biorefineries more economically viable is to recover and valorize all generated by-products during the biomass...

Cellulose and Lignin in Additive Manufacturing: Potential and challenges in the fabrication of structural nodes for free-form building envelope structures

Alberts Coelho, Alexsander (author)

The building stock and the construction industry combined are responsible for a large share of greenhouse gases emissions. At the same time, every year tons of wood, paper and agricultural residues are wasted instead of recycled and upcycled into the production chain. In the fabrication field, the relevance of additive manufacturing processes is...

A comparative study on suitability of model-free and model-fitting kinetic methods to non-isothermal degradation of lignocellulosic materials

Mahmood, Hamayoun (author), Shakeel, A. (author), Abdullah, Ammar (author), Khan, Muhammad Ilyas (author), Moniruzzaman, Muhammad (author)

The thermal kinetic modeling is crucial for development of sustainable processes where lignocellulosic fuels are a part of chemical system and their thermal degradation eventuates. In this paper, thermal decomposition of three lignocellulosic materials (bagasse, rice husk, and wheat straw) was obtained by the thermogravimetric (TG) technique...

Occurrence and fate of aromaticity driven recalcitrance in anaerobic treatment of wastewater and organic solid wastes

Aboudi, Kaoutar (author), Ahmed, Banafsha (author), Tyagi, Vinay Kumar (author), van Lier, J.B. (author)

Aromatic compounds such as aromatic amines (AAs) or lignocellulose biomass derivatives are often recalcitrant to biological processes (i.e., anaerobic digestion). The level of recalcitrance is usually explained by the biochemical structure of the compounds, which determines their removal. AAs are present in dye wastewaters mainly originated...

New insights on the estimation of the anaerobic biodegradability of plant material: Identifying valuable plants for sustainable energy production

Pabón-Pereira, Claudia P. (author), Hamelers, H. V.M. (author), Matilla, Irene (author), van Lier, J.B. (author)

Based on fifteen European plant species, a statistical model for the estimation of the anaerobic biodegradability of plant material was developed. We show that this new approach represents an accurate and cost-eective method to identify valuable energy plants for sustainable energy production. In particular, anaerobic biodegradability (B<sub...
