Sebigas-Cótica

What Sebigas-Cótica does

Sebigas-Cótica is a Porto Alegre-based joint venture between Italy's Sebigas and Brazil's Cótica that designs, builds, and supports anaerobic biodigestion plants producing biogas and biomethane from organic waste. Its portfolio centers on two proprietary reactor architectures: the CSTR (Continuous-flow Stirred Tank Reactor) for solid, pasty, and liquid biomasses, developed with fluid-dynamics input from the University of Bologna, and the CLBR (Covered Lagoon Bio Reactor) for large-volume agroindustrial effluents such as sugarcane vinasse, palm oil mill effluent (POME), tapioca wastewater, and swine manure. The company monetizes through turnkey engineering, procurement and construction (EPC) contracts spanning feasibility studies, biomass analysis, detailed engineering, and plant assembly, supplemented by recurring operation, maintenance, and remote-monitoring services delivered via the proprietary SEBI SMART CONTROL platform across 60+ plants in operation and 130+ biodigesters delivered.

Sebigas-Cótica serves enterprise and municipal clients across five primary verticals: sugar-energy mills, palm oil producers, cassava processors, broader agroindustrial operators, and municipalities targeting landfill diversion through organic-fraction treatment. Revenue mechanics combine project-based professional services, managed waste-treatment services (notably through the Bioo platform co-developed with EB Capital under a R$600 million commitment), and biofertilizer (digestate) sales as a byproduct stream. Go-to-market is direct enterprise sales with customized per-project engineering and economic feasibility assessments, supported by content marketing, industry events (Fenasucro, Palmex), and a multilingual website.

The company is structurally backed by Gruppo Industriale Maccaferri, which provides operational expertise and direct plant-operation know-how across its 18 owned biogas plants. Recent strategic activity positions Sebigas-Cótica as a leading Brazilian biomethane platform: São Martinho's flagship vinasse-to-biomethane plant at Santa Cruz, the Sulgás biomethane supply contract in Rio Grande do Sul, and a 2025 pilot with Toyota Tsusho and Toho Gas on sugarcane-residue biomethane. Geographic reach spans Brazil and Southeast Asia (palm oil and cassava), and the company claims the largest biodigestion plant references in the Americas.

Revenue model

1. Biogas/Biometano Plant Development: Complete biogas plant development from feasibility studies, engineering design, construction, and assembly to operation support. Revenue generated through project-based engineering and construction contracts for industrial biogas and biomethane facilities.
2. Waste Treatment Services: Receiving and treating waste and effluents from third parties such as industries and effluent treatment plants. Converts environmental treatment costs into revenue for both the company and waste generators.
3. Biofertilizer Sales: Digestate (biofertilizer) byproduct sales from biodigestion process, high agronomic power fertilizer for agricultural use, can be separated into solid and liquid fractions or enriched and marketed as organomineral compound.

Core offering

Sebigas-Cótica designs, builds, and provides operational support for industrial-scale biogas and biomethane plants that convert organic waste (sugarcane vinasse, POME, cassava effluent, swine manure, municipal organic fraction, and other agro-industrial residues) into renewable energy and biofertilizer. Its core technology stack consists of two proprietary biodigester architectures—CSTR for mixed-phase biomass and CLBR for large-volume liquid and solid waste—delivered as turnkey projects from feasibility and engineering through construction and assisted operation, including the SEBI SMART CONTROL remote monitoring platform.

Product overview

Sebigas-Cótica is a joint venture between Sebigas and Cótica offering a comprehensive portfolio of biogas and biomethane solutions. The core offerings include two proprietary biodigester technologies: CSTR (Continuous-flow Stirred Tank Reactor) for solid, pasty, and liquid biomasses, and CLBR (Covered Lagoon Bio Reactor) for large volumes of liquid and solid agro-industrial waste. These technologies produce biogas which can be converted to biomethane through purification systems. The company provides complete services spanning investment decision support (biomass analysis, feasibility studies), solution development (process and detailed engineering), construction and assembly, and ongoing operation support including the SEBI SMART CONTROL remote monitoring software. Solutions target three main markets: sugarcane/palm oil/cassava agroindustry, general agro-industrial operations, and municipal organic waste (OFSUW). Plant capacities range from 250 kW to over 10 MW.
