| Feedstock: | Biowaste |
| Product: | Biomass (dispersed, disrupted, emulsified, extracted, homogenised) |
Ultrasonication is a physical treatment to disperse, disrupt, emulsify, extract, and/or homogenise biomass beside others via the application of ultrasonic frequencies (>20 kHz).
Feedstock
Origin and composition
The requirements on the origin and composition of the feedstock may vary since the ultrasonication can be utilised at various points in the value chain of biowaste valorisation.
Process and technologies
Product
Ultrasonication can be used to produce:
- Biofuels
- Emulsions (such as nanoparticles, nanoemulsions, nanocrystals, liposomes, wax emulsions)
- Extracts from biomass (such as polysaccharides[1], oil, anthocyanins and antioxidants[2])
- Purified wastewater
Furthermore, ultrasonication is also utilised in following processes:
- Adhesive thinning
- Cells disruption
- Degassing liquids
- Polymer and epoxy processing
- Ultrasound assisted oxidative desulfurisation of crude oil[3]
