It happens every time. You arrive in WCPT and think “What a 
great atmosphere!” there’s something in the air, an energy 
that invigorates you and fills you with positive emotions 
sharing your knowledge with your colleagues. Together, face-
to-face, we will shape the future of particle technology. 
It’s time to reconnect, meet again, enjoy networking with 
your colleagues in a safe environment discovering a unique 
way of living in Madrid.
Particle technology has significantly contributed since many 
years ago to achieve a better life, providing solutions not 
only to improve industrial processes (chemical, 
pharmaceutical, food production, mining, energy, …) but also 
to protect our environment and to provide us better health, 
in summary, pave the way for more sustainable development of 
our society.
The scientific program outlined covers the most relevant 
topics nowadays for industry and our society. WCPT9 main 
topics are:
• Particulate solids handling
• Particle and particulate systems characterization
• Particle processing
• Particle-fluid systems: fluidization and multi-phase flow
• Particle formation and design
• Particle separation
• Aerosol particles
• Nanoparticles: production, characterization, and 
applications
• Modelling and simulation
• Science, Technology, Engineering, and Design in particle-
based materials and products.
Beyond these main topics, Joint Events (JE) will be also 
organized in engineering, scientific, or technically related 
fields, where particle technology is present. Three WCPT9-JE 
have been already confirmed:
• Challenges of microplastics: analysis and control.
• III ANQUE-DECHEMA Leading-edge conference “Particle 
Technology. Shaping the future”.
• Multidimensional particle properties: characterization, 
separation, and application.
As in previous editions, WCPT9 aims to receive contributions 
from all around the world. WCPT9 aims to count with 8 
plenaries, 50 keynotes, around 200 oral presentations, 150 
flash oral presentations, and 200 poster communications 
covering a wide range of areas related to particle 
technology. Under the theme “Exploring beyond limits”, WCPT9 
aims to engage the whole community on particle technology in 
the different continents and their countries through an 
outreach and promotion program specifically designed for 
this purpose.
