en.Wedoany.com Reported - The biogas laboratory (Labiogás) of the Brazilian International Renewable Energy Center – Biogas (Centro Internacional de Energias Renováveis – Biogás, CIBiogás) has received a ten-year accreditation for its Biochemical Methane Potential (BMP) testing from the General Coordination of Accreditation of the National Institute of Metrology, Quality and Technology (CGCRE/Inmetro, CRL 1014) on the occasion of its 15th anniversary. The accreditation is based on the ABNT NBR ISO/IEC 17025:2017 standard and aims to ensure that the laboratory provides reliable, impartial, and rigorous data support in the growing biogas industry.
Labiogás has been operating since 2011, predating the official establishment of CIBiogás. The laboratory has completed over 50,000 tests, analyzing more than 500 types of substrates and mixtures, and can currently analyze over 60 samples simultaneously. Its services cover not only Brazil but also extend to Uruguay, Paraguay, Chile, Colombia, and Jordan. BMP testing is a key tool for assessing the biogas generation potential of waste, used to estimate energy feasibility, system sizing, and project return potential. This accreditation is not a mandatory industry requirement but a voluntary technical choice by CIBiogás to ensure data quality, traceability, and confidentiality.
Daiana Gotardo Martinez, Technical Director of CIBiogás and an environmental engineer, stated that the laboratory connects the potential of each waste type to the reality of each project, providing safety for decisions involving investment, engineering, and energy strategy. Franciele Natividade, Manager of Labiogás and an environmental engineer, noted that the laboratory's work aims to answer client questions about waste gas production capacity, feeding ratios, stability risks, and the effectiveness of biotechnological products using methodology, traceability, and technical interpretation.
According to the "2025 Brazilian Biogas Panorama," Brazil has registered 1,803 biogas plants, of which over 1,700 are in operation, with an estimated annual production of 4.96 billion cubic meters. Over the past five years, the number of plants has grown at a compound annual rate of 15%, and production has increased by 13%. Biomethane now accounts for 34% of Brazil's biogas utilization, although this proportion is concentrated in a few large plants. The laboratory's development has accompanied the industry's transition from power generation and waste management to emerging routes such as biomethane, syngas, renewable methanol, and sustainable aviation fuel (SAF). The laboratory's role as a technical risk control node in the "waste-to-energy" value chain is becoming increasingly prominent.
In addition to BMP testing, the laboratory conducts physicochemical analyses of substrates and digestate, including indicators such as total solids, fixed solids, volatile solids, alkalinity, pH, FOS/TAC, chemical oxygen demand, sulfates, ammonium, nitrogen, phosphorus, and potassium. Since 2018, the laboratory has used laboratory-scale reactors such as the Continuous Stirred-Tank Reactor (CSTR) and the Batch Leachate Circulation (BLC) model to simulate actual digestion system operating conditions, providing customized tests for clients to reduce technical and economic risks. Currently, the laboratory is planning to procure a solid-state laboratory-scale reactor to expand its support capabilities for new technologies such as dry anaerobic digestion.
