In preparation for the 5th South Brazilian Biogas and Biomethane Forum, a webinar presents cases and discusses potential for the rural environment

The virtual meeting is free and takes place on March 16, Thursday, from 14 pm. Activity takes place in partnership with IDR/PR, EPAGRI/SC and Emater/RS-ASCAR.

Biogas in the Rural Environment. This is the theme of the webinar that precedes the 5th South Brazilian Forum on Biogas and Biomethane. The online meeting takes place on March 16, Thursday, from 14 pm, with transmission on the Youtube page of the Forum @forumsulbrasileirodebiogas1250 ( Mediated by Ricardo Steinmetz, an analyst at Embrapa Suínos e Aves and president of the Brazilian Society of Specialists in Waste from Agricultural and Agroindustrial Production (Sbera), three cases of biogas production plants installed on rural properties in southern Brazil will be shared.

The online activity counts on the organization of the 5th South Brazilian Biogas and Biomethane Forum, in partnership with the Rural Development Institute of Paraná (IDR/PR), the Agricultural Research and Rural Extension Company of Santa Catarina (EPAGRI/SC ) and Emater/RS-ASCAR.

Speakers will be:

Fabio Heck from the company Bioköhler, and rural producers Valdir and Noemia Rossetto, who will talk about “Biogas in Swine Farming: an example of viability at Granja Rossetto (Toledo/PR)”.

- Osnei Muniz, from EPAGRI/SC, Vilmar and Bianca Bossy, father and daughter, share the case “Small-Scale Biodigester for Cattle: Experiences at the Bossy Family Property (Santa Terezinha/SC)”.

João Sampaio, from Emater/RS-ASCAR, and Nestor Reckziegel present the work on “Sustainable Milk Production: case of Granja Reckziegel (Paverama/RS)”.

“The webinar is an important moment to show real cases, in which the biogas produced is used by rural producers. It is also a space where you can learn about the experience of other pork and beef producers and learn about the subject, from the possibility of using biogas for cooking and for generating electricity”, points out Ricardo Steinmetz, an analyst at Embrapa Suínos and Aves and president of the Brazilian Society of Specialists in Waste from Agricultural and Agroindustrial Production (Sbera), who will mediate the meeting. After the explanations, the webinar opens space for questions and debates.


The participants of the meeting and the audience that will follow the webinar will be able to discuss the strength of the rural environment in the production of biogas. The substrates used to generate biogas in Brazil are divided into three categories: agriculture, industry and sanitation. Agriculture involves animal husbandry activities, such as poultry, cattle, goats, pigs, among others.

In 2021, according to the technical note Panorama do Biogás no Brasil, carried out by CIBiogás, the agricultural sector was responsible for 80% of the biogas plants in operation in the country. While the industrial sector and the sanitation sector contributed 11% and 9%, respectively, in the number of plants. In southern Brazil, there are 191 plants installed in rural areas, with emphasis on the state of Paraná, which accounts for more than half of this number.

The example of Paverama, in Rio Grande do Sul

Agronomist Nestor Luis Reckziegel will present the experience of the biogas plant at Granja Reckziegel, in Paverama (RS), in operation since December 2022. He and his father, Enidio José Reckziegel, manage the rural enterprise that has dairy cattle production and adds up to 444 heads.

Resulting from the waste of 200 cows, the daily production of 200m³ of biogas is used to generate electricity and biofertilizer, used on the farm. The property has an 8.400m³ biodigester with an energy production capacity of 70 kilowatt-hours (kWh) and meets 70% of the demand.

EmaterRS – ASCAR monitors the development of the project and assisted the family in forwarding funding for the implementation of the initiative.


In Santa Terezinha (SC), biogas benefits family property

In Santa Catarina, Epagri monitors the biogas plant at Chácara das Meninas, in Santa Terezinha. In the webinar, Bianca and her father Vilmar Bossy will talk about how the biogas production system, implemented in October 2021, benefits the family.

The Bossy invest in transforming the manure of 28 dairy cows into biogas for the production of thermal energy and biofertilizer. According to Bianca, 17 years old, a student in the last year of the Agricultural Technician course, the objective of having a biodigester is to give the correct destination to the waste, with a better use.

“The gas generated in the biodigester goes to a stove that heats the water for sterilizing the milking pipe and to the stove in the kitchen. As the kitchen stove has a coil, it is used to heat water for taps and showers. The biofertilizer, on the other hand, is applied to the pastures,” explains the young woman.

Extensionist Osnei Muniz, from Epagri, who is accompanying the project, observes that the system implemented by the Bossy is suitable for small rural properties. He also points out that the system is low cost and uses geomembrane and vinyl canvas.

The technology that emerges in Toledo, Paraná

On the property of rural producers Valdir and Noemi Rossetto, in Toledo (PR), an electricity generation plant is installed using biogas with the treatment of pig waste. The plant has a complete mixture biodigester, with a mechanical agitation and heating system and a volume of 2.500m³ and a generator set with an installed capacity of 75kwh. The entire system was installed by Bioköhler Biodigestores, the company responsible for advising on plant operation.

At Granja Rossetto, the main activity revolves around finishing pig farming, with 3.500 animals housed. Thanks to technology, the property is able to generate electricity for its own consumption, reducing operating costs of the property, which today has a high level of automation in its facilities.

The production surplus is commercialized, and the plant – responsible for significant reductions in the environmental impact – makes it possible to obtain quality biofertilizer destined for the hay and corn planting area that are used in the production of milk that is located on another property – which maximizes agricultural and dairy productivity.

The Biogas plant went into operation in June 2020. After more than two and a half years, it is possible to state that the project has managed to meet the initially proposed objectives, both financially and environmentally.


The largest sectoral event on Biogas in Southern Brazil, the fifth edition of the South Brazilian Forum on Biogas and Biomethane is held by International Renewable Energy Center (CIBiogas) Embrapa Swine and Poultry e University of Caxias do Sul (UCS), and organized by the Brazilian Society of Specialists in Waste from Agricultural and Agroindustrial Productions (sbera).

The program takes place from April 18th to 20th and includes panels, technical visits and a business space. The activities take place in Foz do Iguaçu, in Paraná.
