Moving forward into a second golden age: Innovative and sustainable production of reprocessed starch aerogels

Bioaerogels are nanostructured materials with potential applications from biomedicine to environmental sciences. Their production at large scale needs to cause minimal environmental impact. Thus, designing strategies for a successful end-of-life handling is essential. Reprocessing and recycling are...

description Bioaerogels are nanostructured materials with potential applications from biomedicine to environmental sciences. Their production at large scale needs to cause minimal environmental impact. Thus, designing strategies for a successful end-of-life handling is essential. Reprocessing and recycling are favorable alternatives to disposal, allowing the material to remain in use by maintaining its original properties. This work studies the reprocessing of polysaccharide aerogels into new aerogels for the first time. Three different reprocessing methods for starch aerogels are proposed, all of which avoid the use of energy-intensive techniques and hazardous reagents.
