Biogas: Transforming Waste into Profit in Industry – Environmental and Economic Benefits

Biogás: Transformando Resíduos em Lucro na Indústria - Benefícios Ambientais e Econômicos

The global energy landscape is undergoing transformation, driven by sustainable solutions like biogas. Derived from the decomposition of organic waste, such as food scraps, agricultural waste, and sewage, biogas is a renewable energy source that can play a crucial role in the transition to cleaner and more efficient sources. In addition to being an energy alternative, biogas also promotes the reduction of the environmental impact associated with the improper disposal of waste, according to CIBiogás.

Environmental Benefits of Using Biogas

The use of biogas significantly contributes to the reduction of greenhouse gas emissions. By replacing fossil fuels, biogas helps decrease the amount of CO₂ and methane released into the atmosphere, two of the main culprits of global warming. In 2021, for example, biogas plants in Brazil produced 2.35 billion Nm³, a 10% increase over the previous year, showing a growing trend in the adoption of this technology.

Another environmental benefit of biogas is the utilization of organic waste, which would otherwise be discarded in landfills. This process not only minimizes soil and groundwater pollution but also reduces problems of foul odors and the proliferation of disease vectors. Furthermore, biogas production aligns with the principles of the circular economy, where waste is transformed into valuable resources.

Economic Advantages of Biogas in the Industry

From an economic standpoint, biogas offers several advantages for the industry. The partial or total replacement of traditional energy sources with biogas can result in significant reductions in operational costs. Additionally, companies can generate additional revenue by selling excess energy or carbon credits. The National Bank for Economic and Social Development (BNDES) approved financing of R$ 80 million for the construction of a biogas and electricity production unit from sugarcane waste, highlighting the economic potential of this technology.

Tax incentives and government policies also play a key role in the sector’s growth. Innovative projects, such as those by Eva Energia, not only promote sustainability but also create jobs and boost regional economic development.

Applications of Biogas in Industrial Processes

The use of biogas in the industry goes beyond electricity generation. It can be used as a vehicle fuel, in heating systems, and even as raw material in industrial processes. The agricultural sector, for example, is responsible for 80% of the biogas plants in operation in Brazil, using agricultural waste to produce energy.

Produced by CIBiogás, the Panorama of Biogas in Brazil 2023 points out that the current production of the 1,365 biogas plants in operation in the country is 4.15 billion Nm³/year. To give an idea of the market possibilities, the estimate is that production could reach 10.8 billion Nm³/year in the short term, reaching up to 84.6 billion Nm³/year in the long term.

The study also shows that the industrial sector can better take advantage of the benefits of biogas. It is only second among the plants in operation, corresponding to 20% of the total, behind agriculture (17%), Urban Solid Waste, and Sewage (63%).

Future of Biogas: Trends and Innovations

The prospects for the future of biogas are promising. Increasing awareness of environmental challenges and technological advancements indicate continuous sector growth. According to CIBiogás, biogas production in Brazil is expected to grow significantly in the coming years, with new plants coming online and increasing installed capacity.

Technological innovations are also improving the efficiency of biogas production and utilization processes. The adoption of new technologies and the integration of smart waste management systems are trends that promise to make biogas even more competitive in the energy market.


The adoption of biogas as an energy source represents a unique opportunity for the industry, combining environmental and economic benefits. The growth of the biogas sector in Brazil, driven by incentive policies and technological advancements, points to a future where sustainability and energy efficiency go hand in hand. Investing in biogas will not only contribute to a greener world but also bring competitive advantages to companies that adopt this technology.
