Practice abstract- Olive mill wastewater to high added particles for multiple industrial uses
The process applied is known as hydrothermal carbonization. The alpechin is first concentrated (to achieve 30 to 40% concentration of solids) and placed in a sealed reactor together with iron salts. Under controlled temperature and pressure, the organic matter acts as a natural reducing agent, trans

Lyhyt kuvaus
CALPECH, a Spanish company spin off from the University of Alicante, has developed a simple and circular solution that makes this waste valuable. Using a patented thermal process CALPECH converts alpechin into a new liquid containing encapsulated zero-valent iron nanoparticles (CE-nZVI).
Pilot installations have demonstrated that the system can handle from 3 cubic meters of alpechin per day (small cooperative scale) up to 21 cubic meters per day (industrial unit). The process runs continuously and can be adapted to the seasonal operation typical of olive mills. The treated wastewater shows a strong reduction in phenolic compounds. Its valorisation requires further refining, to obtain either separated fractions, or the whole treated batch.
