El Granjero, the second-largest egg producer in El Salvador, invested US$2.5 million in 2017 to build a biogas plant, proving that there is a solution to the thorny issue of environmental pollution caused by most poultry companies in the country.
Still in its early stages and with few players, the poultry sector in El Salvador is taking small steps toward environmentally sustainable production by using its biological waste to generate biogas and, in turn, electricity –an equation that benefits the natural environment, communities, and the farms themselves.
“I don't know of a more sustainable technology for the transformation of society than biogas,” said Professor Alex Enrich-Prast, an activist for this energy alternative with a highly diversified and decentralised expansion in Brazil.
A community bakery, family production of fruit pulp, and the recovery of water springs are some of the initiatives of the
Energy of Women of the Earth, organised since 2017 in the state of Goiás, in central-western Brazil.
Biogas sounds like redemption, the conversion of the sinner. Its production involves extracting energy from filth, from the most disgusting environmental pollution, and at the same time avoiding the worsening of the global climate crisis.
Just to obtain a good fertilizer it was worth building a biodigester, says Cuban farmer Alexis García, who proudly shows the vegetables in his family's garden, as well as the wide variety of fruit trees that have benefited from biol, the end product of biogas technology.
A bakery, fruit pulp processing and water pumped from springs are empowering women farmers in Goiás, a central-eastern state of Brazil. New renewable energy sources are driving the process.
In a win-win relationship, a segment of El Salvador's agribusiness industry is taking steps to ease the tension of the historic socio-environmental conflict caused by poultry and pig farms, whose waste has caused concern and anger in nearby communities.
A new technology that has arrived in rural villages in El Salvador makes it possible for small farming families to generate biogas with their feces and use it for cooking - something that at first sounded to them like science fiction and also a bit smelly.
The city of Franca is an example of basic sanitation in Brazil. In addition to providing universal treated water and sewage to its 352,500 inhabitants, it extracts biogas from wastewater and refines it to fuel its own vehicles.
"The biodigester really gives a huge boost to those who have the courage to do things," said Maria das Dores Alves da Silva, based on her own experience as a 63-year-old small farmer.
It is the “best energy,” according to its producers, but biogas from livestock waste still lacks an organized market that would allow it to take off and realize its potential in Brazil, the world's largest meat exporter.
The first five biomethane-fuelled buses in the Cuban municipality of Martí will not only be a milestone in the country but will also represent a solution to the serious problem of transportation, while reducing emissions of greenhouse gases and bolstering local development.
Mayra Rojas is one of a small but growing number of people in Cuba benefiting from the production of biogas, a renewable energy source still little used in a country highly dependent on fossil fuels.
The increasing productivity with which humankind generates waste has gained at least one sustainable counterpart: the extraction of biogas from landfills, a growing activity in Brazil.
Standing in front of a blue flame on her stove, getting ready to brew coffee, Mayra Rojas says the biodigester built in the backyard of her home in western Cuba has become a key part of her daily life and a pillar of her family's well-being.
The multitude of solar panels stands out along a dirt road in an unpopulated area. Although located just an hour's drive from Buenos Aires, the new solar park in the municipality of Escobar is in a place of silence and solitude, symbolic of the difficulties faced by renewable energies in making inroads in Argentina.
Three giant concrete cylinders with inflated membrane roofs are a strange sight in the industrial park of Zárate, a world of factories 90 kilometers from Buenos Aires that heavy trucks drive in and out of all day long. They are the heart of a plant that is about to start producing energy from agro-industrial waste, for the first time in Argentina.
First came sugar. For four centuries, it was the main sugarcane product in Brazil. But since the 1970s sugarcane has grown and diversified as a source of energy: ethanol, electricity and biogas.
The number of victims of serious burns, some fatal, has increased in Brazil. Without money to buy cooking gas, the price of which rose 30 percent this year, many poor families resort to ethanol and people are injured in household accidents.
Yunia Cancio cooked with firewood until a few years ago, when a biodigester was built on her family’s El Renacer farm in Cabaiguán, a municipality in the central Cuban province of Sancti Spíritus, under the Biomass Cuba project. That change meant a lot for her family’s quality of life, but it was not the only one.
