Agrosistemi Srl a Socio Unico

Agrosistemi Srl a Socio Unico is an Italian environmental services and laboratory analysis company headquartered in Piacenza, Italy, with more than twenty years of experience in the treatment and recovery of biological sludge originating from municipal wastewater purification plants. The company offers a fully integrated approach to sludge management — encompassing physical and chemical treatment, quality-control laboratory analysis, logistics, and administrative management of all regulatory documentation — making it a single-point partner for wastewater utilities and industrial operators throughout Italy. Agrosistemi operates two active treatment plants: its principal installation at Loc. Ca' Morta in Piacenza and a second facility at Via delle Aie, Savio di Cervia, in the Ravenna province.

At the heart of Agrosistemi's operations is a proprietary sludge-treatment platform that converts biological waste into compliant organic fertilizer products. The company produces four categories of output: Biosolfato (Biosulfate) and Mild Wet Oxidation products derived from sludge classified as waste, and No More Sludge and Fertilizzante EU (EU Fertilizer) from sludge that exits the waste classification. These products are manufactured under strict quality controls and intended for agricultural soil amendment applications. Agrosistemi also maintains an active research and development programme backed by multiple proprietary patents, with emerging technologies under investigation including Hydro Thermal Dewatering, Hydro Thermal Liquefaction, and advanced metals-removal processes — reflecting a sustained commitment to innovation in environmental biotechnology.

Agrosistemi's in-house quality-control laboratory has been accredited by ACCREDIA (Italy's National Accreditation Body) under accreditation number 1734 L since November 2018, in conformity with UNI EN ISO/IEC 17025. This accreditation confirms the laboratory's technical competence and management-system compliance across its defined scope of testing activities. Additionally, the laboratory holds official recognition from MIPAF (Ministero delle Politiche Agricole, Alimentari e Forestali — Ministry of Agricultural, Food and Forestry Policies) as authorized laboratory number 80 for fertilizer analysis, enabling it to issue analytical reports carrying full legal validity in Italian regulatory proceedings. Quality assurance practices include systematic participation in interlaboratory proficiency circuits, use of certified reference materials, and routine analysis of internal control samples against validated acceptance criteria.

The laboratory performs testing across a broad range of environmental and agro-industrial matrices. For soils and land, it provides control services covering both reclamation (remediation compliance) and agronomic aspects of sludge and compost land-spreading, determining all parameters required by current Italian and EU legislation. Organic waste, digestate, fertilizers, and soil improvers undergo the full suite of chemical and physical analyses mandated by applicable authorizations and EU regulations. Wastewater and groundwater are tested for microbiological compliance parameters, while sewage sludge testing addresses the chemical, physical, and microbiological requirements of Italian law and European directives including Directive 86/278/EEC — which explicitly prescribes monitoring of heavy metals such as cadmium, copper, nickel, lead, zinc, mercury, and chromium in sludge intended for agricultural use. Growing media (substrates) are evaluated for water retention curves and nitrogen immobilization (NDI). Waste characterization for the assignment of European Waste Catalogue (EER/CER) codes is also performed, supporting proper waste classification, disposal, and recovery routing.

Among the specialized analyses offered, the laboratory provides detection and quantification of organic contaminants including pesticides, phytopharmaceuticals (plant-protection products), and PFAS (per- and polyfluoroalkyl substances) — priority pollutants in sludge-to-land applications under evolving EU regulatory scrutiny. Microbiological analyses cover pathogens and hygiene indicator organisms relevant to sludge and fertilizer safety. Additional capabilities include Legionella identification with serotyping in water matrices, biological stability measurement using OUR (Oxygen Uptake Rate) and BMP (Biochemical Methane Potential) assays for digestate and organic waste, and dynamic olfactometry for the quantitative assessment of odor emissions from treatment facilities. Analytical methods are drawn from recognized national and international bodies — UNI, EPA, ISO, and IRSA — and are applied alongside internally validated procedures, all operated within the ISO/IEC 17025 accredited quality framework.

Agrosistemi primarily serves clients in the environmental and water-services sector — municipal wastewater treatment authorities, industrial wastewater operators, and biogas or digestate producers — as well as agricultural input manufacturers and distributors requiring certified fertilizer analysis. The company's work sits at the intersection of environmental compliance, circular economy, and agricultural productivity: by certifying that recovered organic materials meet the compositional, microbiological, and contaminant thresholds established by Italian and EU legislation, Agrosistemi enables the legally compliant and agronomically safe return of nutrient-rich materials to productive soils. Industry affiliations include membership in Assofertilizzanti (Italy's fertilizer industry association) and active regulatory engagement with ECHA (European Chemicals Agency).

In January 2022, Agrosistemi was acquired by Sdiptech AB, a Swedish listed infrastructure technology group focused on sustainable essential services, providing the company with additional capital and group resources while preserving local operational expertise across its Piacenza and Ravenna sites. With over two decades of continuous operation, ACCREDIA ISO/IEC 17025 accreditation (number 1734 L), MIPAF ministerial recognition as an authorized fertilizer laboratory, and an active patent portfolio in sludge-processing innovation, Agrosistemi represents a technically credible and regulatory-grade analytical partner for organizations managing biological sludge treatment, organic waste recovery, fertilizer certification, or land-spreading authorization under Italian and European environmental law.
