What Rastro Biodigestores does

Rastro Biodigestores is a privately held Brazilian environmental engineering company founded in 2013 and headquartered in Araruna, Paraná, that designs and builds custom anaerobic biodigesters and biogas utilization systems for agricultural producers and food processors. Its core offering is turnkey biodigester construction, scoping each project against the client's effluent composition, daily volume, terrain, and regulatory context, then delivering through a partnership network that covers dredging, earthworks, environmental licensing, electrical engineering, generator manufacturing, and irrigation. The company also sells proprietary equipment — including the QBA automated biogas burner, FLARE pressure relief device, German-technology biogas desulfurizer, MIXER homogenizer, and a biological sludge recirculation system — and bundles them with custom control/automation software for plant optimization. Biofertilizer (NPK-rich digestate) is produced as a byproduct.

The business generates revenue from one-time turnkey project delivery, equipment sales, ongoing maintenance and technical assistance, and biogas utilization management (thermal energy, electric energy, or biomethane applications). Customer segments are vertically focused on Brazilian agribusiness: cassava flour and starch processors (farinheiras and fecularias), beef and dairy cattle operations, swine farms, slaughterhouses (frigoríficos), and dairy plants. Quoted customer outcomes include roughly 50% reduction in firewood consumption for cassava drying and stated ROIs of approximately 18 months for thermal energy applications and 36 months for electrical generation. The company is founder-led (Gelson Vieira), has 11–50 employees, and operates without external institutional capital. Geographic reach is concentrated in Paraná with documented activity in Alagoas and broader Brazilian trade-show presence; in 2022 the company rebranded to 'Rastro Biodigestores | Gestão Ambiental'.

Core offering

Rastro Biodigestores designs, builds, and maintains custom biodigester systems for the treatment of organic effluents and the generation of biogas from agricultural and food-processing waste streams. The company delivers turnkey projects including proprietary equipment (QBA automated biogas burner, FLARE, desulfurizer, mixer, biological sludge recirculation system) and offers associated services such as waterproofing, biofertilizer production, and thermal and electrical energy generation for rural properties, slaughterhouses, swine farms, cassava starch plants, and dairy operations across Brazil.

Product overview

Rastro Biodigestores is a specialized biodigester construction and environmental management company offering a comprehensive portfolio of products and services. The core offering is custom biodigester construction serving farinheiras, fecularias, cattle farming, slaughterhouses, and dairy plants. The company provides a complete 'turnkey' solution encompassing project design, execution, and plant management. Key products include the QBA Automated Biogas Burner, FLARE pressure relief device, German-technology biogas desulfurizer, MIXER homogenizer, and biological sludge recirculation system. Services include thermal and electrical energy generation from biogas, waterproofing, and environmental licensing. The portfolio integrates these products to deliver complete biodigestion solutions that transform organic waste into biogas (for thermal/electrical energy) and biofertilizer.

Functional benefit

Products and services

• Biodigester Systems (Biodigestores) Custom-designed anaerobic digestion systems that treat organic effluents from agricultural and food-processing operations while capturing biogas for energy and biofertilizer generation; delivered as turnkey projects for rural properties, slaughterhouses, swine farms, cassava starch plants, and dairy facilities.
• QBA Automated Biogas Burner (Queimador Automático de Biogás QBA) Rastro's proprietary automated biogas burner that enables controlled combustion of captured biogas for thermal applications on biodigester-equipped properties.
• FLARE Biogas Burner Proprietary flare device used to safely burn off excess biogas from biodigester systems, ensuring operational safety and regulatory compliance.
• Biogas Desulfurizer (Dessulfurizador) Proprietary desulfurization unit that removes hydrogen sulfide from raw biogas, protecting downstream burner and engine equipment and improving biogas quality.
• Biogas Mixer (MIXER) Proprietary mixer used inside biodigester vessels to homogenize organic effluent, improving the efficiency of the anaerobic digestion process and biogas yield.
• Biological Sludge Recirculation System Proprietary recirculation system that returns biological sludge within the biodigester to improve microbial activity and overall digestion efficiency.
• Thermal and Electrical Energy Generation from Biogas Service delivering usable thermal energy (substituting firewood and LPG) and electrical energy (via generators) generated from biogas produced by Rastro Biodigestores' installed systems, with published equivalences such as 600 m³/day of biogas producing energy equivalent to 350 kWh of electricity or 25,000 kg of firewood.
• Biofertilizer (Biofertilizante) Byproduct from biodigester operations, distributed as nutrient-rich biofertilizer for agricultural application on the rural properties and agro-industrial sites served by the company.
• Biodigester Waterproofing (Impermeabilização de Biodigestores) Specialized waterproofing service performed during construction and maintenance of biodigesters to prevent leakage of effluent and biogas, ensuring structural integrity and gas capture efficiency.
