The vinhaça is the largest waste from ethanol production — for every liter of ethanol produced, 10 to 15 liters of vinhaça are generated. For decades, it was discarded as an environmental problem. Today, with biodigestion technology, vinhaça is one of the most promising raw materials for the production of biogas and biomethane — and a source of complementary income that can represent 10 to 20% of the plant's revenue.
The biomethane from vinhaça has a calorific value equivalent to natural gas and can be used as vehicle fuel (compressed natural gas), industrial input, or injected into the gas distribution network. In Brazil, the biomethane market is rapidly expanding — with over 200 projects underway and the potential to replace a significant portion of the natural gas imported from Bolivia.
When the biogas from vinhaça is converted into biomethane with injection purity for the network, this segment can greatly contribute to job and income generation in Brazil.
Join our strategic actions for the implementation of the best solutions in the Brazilian agricultural sector. Our activities, studies, and advanced research cover 20 chains and 255 segments of the national agro sector — from the grain chain to sustainable extractivism, passing through horticulture, fruit farming, livestock, and much more.
The series Innovation for Brazil to Produce More was developed precisely to identify and implement the best available solutions in Brazil and worldwide, across the 255 segments of the agricultural sector — with accessible technical language, updated data, and a focus on practical results for producers, suppliers, governments, and marketers.
1. Opportunities for Small Rural Producers
How the sugarcane producer can participate in the biomethane revenue from vinhaça
The sugarcane producer supplying to a plant with a biomethane project from vinhaça has the potential to negotiate additional benefits in the supply contract — as high-quality vinhaça (low solid content) produces more biogas per cubic meter.
✔ Cane with high ATR produces more carbon-rich vinhaça — better yield in biogas
✔ Participation in biogas projects via cooperatives — collective access to the project and revenue
✔ RenovaBio certification for CBIO credits via biomethane — additional revenue for decarbonization
✔ Concentrated vinhaça as a biofertilizer for the sugarcane field — reduces fertilization costs by 30 to 50%
✔ BNDES projects and Green Yellow Bank for the installation of biodigesters
The E-Book 01 — Strategic Manual for Small Rural Producers presents, in detail, the best solutions for the segment and the other 254 of Brazilian agribusiness — focusing on method, cost reduction, and progressive growth from Agro 1.0 to Agro 6.0. Access now for BRL 99.00 →
2. Opportunities for Micro and Small Local Suppliers
What equipment and services does the sugarcane biogas chain demand?
The market for equipment for biodigestion of vinhaça is one of the fastest-growing in Brazilian agribusiness — with projects ranging from R$ 5 to R$ 50 million per plant and increasing demand for qualified suppliers.
Solutions by field of engineering applied to the segment
Our activities, studies, and advanced research cover six major engineering fields — and the chain demands solutions in all of them:
Electrical and Computer Engineering — biogas control systems, compressor automation, and flow measurement;
Electronic Engineering and IoT — CH₄, CO₂, H₂S sensors; remote monitoring of biodigesters;
Control and Automation Engineering — temperature control for anaerobic digestion; biomethane upgrading systems;
Mechatronics and Robotics Engineering — covered lagoon biodigesters; biomethane purification systems;
Renewable Energy Engineering — integration of biomethane + bioelectricity + biofertilizer for zero waste;
Data Science and Artificial Intelligence — biogas production models by batch of vinhaça; management of CBIO credits.
✔ Projects and installation of covered lagoon biodigesters — the main technology for vinhaça
✔ Biogas upgrading systems to biomethane (injection pressure)
✔ Biomethane quality monitoring for the gas network
✔ Carbon credit projects via biomethane — CBIO and voluntary market
✔ Vinhaça biofertilizer application systems in the field
The E-Book 02 — Strategic Guide for Micro and Small Local Suppliers maps, segment by segment, business opportunities — focusing on IoT, energy, automation, and specialized technical services. Access now for BRL 99.00 →
3. Opportunities for Municipal Governments
How municipalities can use biomethane for energy and local transportation
Biomethane from local plants can be used to fuel the municipal transport fleet — buses, garbage trucks, and ambulances — with renewable locally sourced fuel, eliminating the dependence on imported natural gas.
✔ Partnership with the plant for biomethane supply to the municipal fleet
✔ Municipal biomethane station — fueling vehicles with renewable natural gas
✔ Carbon credits via biomethane for the municipality — sustainability revenue
✔ Municipal IDM: participation of biomethane in the local energy matrix
✔ Replacement of LPG (cooking gas) with biomethane in schools and municipal kitchens
The E-Book 03 — Reference Guide for Municipal Governments presents the step-by-step process for municipal secretaries and managers to implement effective public policies for the 255 segments of agribusiness. Access now for BRL 99.00 →
4. Opportunities for Small Agricultural Product Merchants
How biomethane creates opportunities for gas distributors and renewable energy services
Biomethane is the fastest-growing renewable fuel in Brazil — and natural gas distributors that add biomethane to their portfolio have access to a differentiated high-margin product with increasing demand from companies with ESG goals.
For transport companies, truck fleets, and logistics firms, biomethane from sugarcane represents 25 to 40% reduction in fuel costs compared to diesel — with 80% lower carbon emissions and independence from oil price fluctuations.
Products with high commercial potential
The main products derived from this segment for local retail and foodservice:
Biomethane for transport fleet — replaces CNG with environmental advantages and competitive cost;
CBIO carbon credits — financial instrument for plants with certified biomethane;
Processed vinhaça biofertilizer — high-demand B2B product for sugarcane and citrus producers;
Consultancy in biomethane projects — high-value service; projects ranging from R$ 5 to R$ 50 million;
Biomethane for local industries — replaces LPG in furnaces and boilers; 30% cost reduction;
Biogas for electricity generation — complementary product to bioelectricity from bagasse.
Merchant profiles and their specific opportunities
✔ Gas distributors: local plant biomethane — differentiated renewable product with higher margins than CNG
✔ Transport companies: biomethane for fleets — 25 to 40% reduction in fuel costs
✔ Energy consultants: biomethane projects — high remuneration and rapidly growing market
✔ Local industries: biomethane for furnaces and boilers — replaces LPG at lower costs
✔ Municipalities: municipal fleet powered by biomethane — sustainability and budget savings
✔ ESG companies: CBIO carbon credits — decarbonization portfolio with traceable origins
Growth strategies for local merchants
The consultant or company that masters the structuring of vinhaça biomethane projects has a R$ 5 billion market in projects over the next 5 years ahead of them. The technical and regulatory complexity creates a barrier to entry that protects early entrants with high margins and long contracts.
The BNDES Green Fund finances biomethane projects under favorable conditions. The BNB/FNE Green supports projects in the Northeast. Finep co-finances innovations in biomethane upgrading and purification technologies.
