Technology details
Name: Ultrasonication
Category:
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

During the ultrasonication treatment ultrasound is transmitted through any physical medium by waves that compress and stretch the molecular spacing of the medium through which it passes[1]. The distance between the molecules will vary as they oscillate about their mean position[1]. When the negative pressure is large enough, the distance between the molecules of the liquid exceeds the minimum molecular distance required to hold the liquid intact, and then the liquid breaks down and voids (cavitation bubbles) are created[1].

Product

Ultrasonication can be used to produce:

  • Biofuels
  • Emulsions (such as nanoparticles, nanoemulsions, nanocrystals, liposomes, wax emulsions)
  • Extracts from biomass (such as polysaccharides[2], oil, anthocyanins and antioxidants[3])
  • 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[4]
