What B-Plas does
B-Plas sbrl is an Italian biotechnology company founded in 2021 and headquartered in Lugo (Ravenna), Italy, that develops and manufactures modular, integrated sludge treatment plants for municipal, industrial, and agro-industrial wastewater operators. Its proprietary technology platform combines hydrothermal carbonization (HTC), filter press dewatering, acidogenic digestion, and aerobic fermentation in four configurable modules — B-Sludge (volume reduction, 50-80% dewatered sludge reduction), B-Poly (PHA biopolymer production), B-Energy (biogas/energy recovery), and B-Fosfor (phosphorus recovery) — supported by a pilot plant at the Caviro Extra site. B-Plas operates as a Società Benefit and a subsidiary of Diemme Filtration, itself part of Aqseptence Group, with Sandvik having announced in June 2026 an agreement to acquire the parent (expected close Q3 2026). Revenue is generated primarily through multi-phase custom turnkey engineering projects (feasibility study → basic → detailed → executive engineering), supplemented by paid laboratory testing and consulting services, and an emerging B2B stream from sale of PHA biopolymers as a bio-based, biodegradable alternative to conventional plastics. The company targets Italian municipal water utilities and industrial customers in food processing, leather tanning, and chemicals, with go-to-market through direct enterprise sales, an expanding network of independent regional agents, and Diemme Filtration's international distribution channels; it actively participates in European trade shows (Ecomondo, IFAT, FILTECH, SMAGUA) and EU-funded projects such as CROSS-LIFE (LIFE21-ENV-IT-CROSS-LIFE) and GREEN4SLUDGE to validate and commercialize its technology.

Revenue model
- Custom Industrial Plant Sales and Engineering: B-Plas designs, engineers, and manufactures custom modular sludge treatment plants sold to industrial and municipal clients. Revenue is generated through multi-phase project engagements: feasibility studies, basic engineering, detailed engineering, and executive engineering leading to plant construction and delivery. The company provides a complete turnkey solution including process design, equipment manufacturing, installation, and commissioning support.
- Process Optimization and Consulting Services: B-Plas offers laboratory testing, physico-chemical and biological characterization of sludge and wastewater, bench-scale experimentation, and technical consulting as paid services. These support the plant sales process and are also offered independently to wastewater treatment operators.
- PHA Bioplastic Production: B-Plas generates revenue from the sale of PHA (polyhydroxyalkanoates) biopolymer produced through its B-Poly module. The raw bioplastic is sold B2B to manufacturers seeking bio-based, biodegradable polymer alternatives to conventional plastics.

B-Plas product offering
Product offeringCore offering
B-Plas designs, engineers, and manufactures modular integrated sludge treatment plants for civil, industrial, and agro-industrial wastewater operators. Its technology combines hydrothermal carbonization (HTC), filter press dewatering, acidogenic digestion, and aerobic fermentation to reduce sludge disposal volumes by up to 80% and convert sludge into PHA biopolymers, biochar, and recovered phosphorus. The company also provides laboratory testing, feasibility studies, and pilot plant demonstration services.
Product overview
B-Plas offers an integrated modular technology solution for sewage sludge treatment, consisting of four core product modules (B-Sludge, B-Energy, B-Poly, B-Fosfor) that work together to reduce sludge volumes and produce valuable outputs. The system employs hybrid thermochemical-biological processes to convert sludge into PHA biopolymers, bio-based crotonic acid, and recovered nutrients. The modular architecture allows customization based on specific industrial needs, supported by a pilot plant facility for testing.
