B-Plas is an Italian company that designs and manufactures treatment plants for agro-industrial, industrial and civil sewage sludge. 

They treat sludge from municipal wastewater plants, industrial facilities, agro-food industries and paper mills. By developing and installing on-site plants, sludge is converted into valuable products and the residual volume needing disposal is reduced by up to 80%. 

Sewage sludge is usually landfilled, incinerated or used for compost. B-Plas's technology reduces sludge volume, sanitises process waters and converts organic carbon in sludge into biodegradable polyhydroxyalkanoate (PHA) biopolymers. This process transforms waste organic matter into valuable, renewable materials that can replace conventional plastics, suitable for use in packaging, agriculture, medical applications and other sectors requiring sustainable, compostable plastics.  

A first B-Plas pilot plant was built in Caviro, Faenza, Italy as part of a demonstration project financed by EIT Climate KIC, in collaboration with the University of Bologna and Caviro Extra, and Spanish and Hungarian partners. 

In order to tailor the plant to the client’s needs, the company looks at the physical and chemical characteristics of the wastewater, conducting tests such as sludge characterization and Hydrothermal Carbonization analysis and optimisation. They also take into account the industrial processes used, to allow for factors such as volume. 

Their goal is to diminish the total amount of waste and make valuable secondary raw materials out of it.
