- Chemical engineering and process safety.
Background:
- Technical lignins are abundant biomass residues with potential for sustainable applications.
- Variability in lignin sources and production impacts its properties and safety.
- Limited safety data hinders large-scale lignin utilization.
Purpose of the Study:
- To comprehensively characterize technical lignins for safety and sustainable use.
- To assess physico-chemical properties, including dust explosion and thermal hazards.
- To establish a safety profile for diverse lignin feedstocks.
Main Methods:
- Characterization of eight technical lignin samples from various origins.
- Analysis of chemical composition, higher heating value, and size distribution.
- Assessment of dust explosion sensitivity/severity and thermal hazard characteristics.
Main Results:
- Technical lignins exhibit significant heterogeneity and variability in safety-related properties.
- Differences in dust explosion sensitivity and thermal hazards were observed among samples.
- Biodegradability varied, impacting overall sustainability assessment.
Conclusions:
- A comprehensive safety characterization of new lignin feedstocks is essential for biorefineries.
- This study provides a foundational safety profile for technical lignins.

Bioplastics derived from microbial processes present a sustainable alternative to conventional petroleum-based plastics. Among these, polyhydroxyalkanoates (PHAs), particularly polyhydroxybutyrates (PHBs), have emerged as prominent candidates due to their biodegradability and biocompatibility. These polymers are synthesized by a variety of bacteria, such as Cupriavidus necator and Pseudomonas putida, which naturally accumulate PHAs as intracellular carbon and energy reserves, especially under...

The microbial conversion of organic matter into biofuels holds potential as a renewable energy source. Among biofuel sources, microalgae are recognized as a highly efficient and adaptable feedstock for biodiesel production, owing to their rapid biomass accumulation, elevated lipid productivity, and capacity to proliferate in diverse aquatic systems, including freshwater, marine, and wastewater habitats. Unlike terrestrial crops, microalgae do not compete for land and can achieve significantly...
