| Technology details | |
| Name: | Ultrasonication |
| Category: | Pre-processing (Physical processes and technologies), Post-processing (Physical processes and technologies) |
| Feedstock: | Biowaste |
| Product: | Biomass (dispersed, disrupted, emulsified, extracted, homogenised) |
Ultrasonication is a physical treatment to disperse, disrupt, emulsify, extract, and/or homogenise biomass via the application of ultrasonic frequencies (>20 kHz). The propagation of sound waves through the biomass results in spontaneous formation and collapse of microsized cavities. This activity produces a hot-spot effect, resulting in high temperature and pressure gradients to form locally, while the overall conditions remain ambient. This effect can be used to break down morphologies, for example for the depolymerisation of lignocellulosic biowaste.[1]
Feedstock
Composition
The requirements on the composition of the feedstock may vary since ultrasonication can be utilised at various points in the value chain of biowaste valorisation.
Pre-treatment
Ultrasonication is often the first step of the pretreatment, although initial sizing may be required.
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[2]. The distance between the molecules will vary as they oscillate about their mean position[2]. 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[2].
The medium for ultrasonication can be water, an organic solvent, or a dilute acid or base.[1]
Product
Ultrasonication can be used to produce:
- Emulsions (such as nanoparticles, nanoemulsions, nanocrystals, liposomes, wax emulsions)
- Extracts from biomass (such as polysaccharides[3], oil, anthocyanins and antioxidants[4])
- 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[5]
Post-treatment
A common application for ultrasonication is breaking down the lignocellulosic structure. The available sugars can then be converted to products such as biofuels, for example by fermentation.[1]

Everywave Srl is a spin-off from UNITECH Srl that specializes in the research, development and production of solutions in the ultrasound technologies. The continuous and rapid technological evolution and the need for ever higher quality standards require the daily research and development of increasingly innovative solutions where quality and reliability play an absolutely vital role in all working processes. Everywave’s mission has always been to find ideas and improvement solutions in the field of ultrasound technologies, with continuous support to its customers in order to optimize their productivity and therefore their competitiveness.
Today, with a specialized biomass treatment plant, the company also produces biogas from the same by-products: a source that reduces the energy supply costs necessary for the company and generates a new source of income. We have designed and produced a special ultrasonic reactor which, integrated with specialized systems for shredding, pumping and process control, represents a solid and efficient technology for controlling and increasing the production yield of biogas.
