Turning waste into value using Poppi’s fine powder recovery technology

An innovative patented system allows fine powder to be automatically reused inside the spray dryer.

In the ceramic industry, optimising the production process means minimising waste, improving product quality and increasing sustainability. Every detail counts, such as the fine dust collected from post-spray-dryer filters. When managed effectively, this valuable resource can be transformed into a clear competitive advantage.

Thanks to innovative patented technology from Poppi Clementino SpA (Reggio Emilia), ceramic manufacturers can now automatically recover and reuse fine powder inside the spray dryer, eliminating waste while ensuring optimal process control. The system is designed for maximum efficiency, significantly improving ceramic production.

The patented system feeds fine powder directly into the spray dryer, eliminating the need for manual intervention. The feed zone has been optimised so that powder is introduced into a strategic area of the spray dryer, preserving the quality of the spray-dried product. Advanced pneumatic transport ensures that the recovered powder is transferred efficiently and without dispersion. If necessary, the fine powder can also be stored in a dedicated silo to be reused later with precise dosing.

This brings clear benefits for ceramic manufacturers. In terms of energy and environmental sustainability, the system reduces waste while lowering energy and water consumption by avoiding a double transition to the liquid state. At the same time it increases spray dryer production yields by up to 3-5%. As a result, this technology cuts costs, enhances product quality and reduces waste.
