Today, despite the development of renewable energy worldwide, fossil fuels , including oil , remain one of the planet's most important resources. Many of the things we use daily, such as plastics, various medications, some snacks, and, of course, fuels, come from oil. However, oil is a non-renewable resource that is being depleted, which necessitates the search for sustainable alternatives.
An innovative and unexpected solution has emerged from the pineapple plant , opening new perspectives on how the agricultural waste sector could become a source of alternative energy. But how is it possible for pineapples to replace oil?
The pineapple plant and its unexplored value
One of the pioneers in this field is Esteban Bermúdez , a young innovator from Costa Rica and co-founder of Escoia , a company focused on transforming pineapple agricultural waste into value-added products. Bermúdez and his partner, Norwegian Bjøorn Utgärd , aim to utilize pineapple plantation waste, giving it a second life by creating a biorefinery capable of producing renewable energy.
Essentially, the inspiration behind this project comes from the circular economy , a concept based on reusing waste to minimize environmental impact. Specifically, pineapple plantations generate a large amount of waste, as they must be renewed every two years to maintain productivity. By converting this waste into biomass , the need to burn it can be reduced—a practice that previously involved the use of pesticides and herbicides, exacerbating the environmental impact.
The process of converting waste to energy
The Escoia project has succeeded in developing a machine capable of treating the biomass of pineapple plants. This machinery adapts the water content of the residues, reducing their humidity from 88% to less than 60%, which facilitates their processing and subsequent conversion into renewable fuels.
Since 2014, Bermúdez and his team have been exploring and analyzing over 43.000 hectares of pineapple plantations in Central America, the world's largest producer of this fruit. From the resulting waste, they can generate not only energy, but also other byproducts such as biofuels , fertilizers , and even feed for cultivating edible mushrooms.
- Biofuel generated from pineapples can make a key contribution to reducing dependence on fossil fuels.
- The circular economy system implemented in this project ensures that pineapple waste is transformed into useful products, reducing the environmental impact.
Similar cases: Pineapple and other fruits as sources of bioethanol
Costa Rica is not the only country exploring alternatives using fruit. In Mexico, student Adriana Barona has launched an initiative to produce bioethanol as a biofuel from fruit waste, such as pineapple. This biofuel is considered second-generation , allowing for greater environmental sustainability by not competing with food crops.
Bioethanol is obtained through microbial fermentation of carbohydrate sources, which reduces its impact compared to first-generation biofuels. In addition, the lignocellulosic biomass used in this type of process is more competitively priced than conventional agricultural feedstocks, making it a viable solution.
Uses and benefits of pineapple fiber
In addition to biofuels, another relevant application is the use of pineapples for the production of natural fibers. At the University of Costa Rica, a group of students has developed a business model in which pineapple waste is transformed into biodegradable rope for agricultural use. This biodegradable rope would replace the polypropylene ropes commonly used in the agricultural sector, thus reducing the carbon footprint generated by these petroleum-derived products.
The project not only seeks environmental benefits, but also social impact , as it involves local producers and workers in the manufacture of this rope, fostering greater social inclusion and providing economic opportunities to pineapple-producing regions in Costa Rica.
As for the process of obtaining this rope, around 374 kg of pineapple leaves are used to produce a single roll of 2.115 meters of rope, which demonstrates the enormous potential that the residues of these crops have. This model is economically viable, and socially responsible, in addition to contributing to the development of a more sustainable economy.
The future of pineapple as a substitute for oil
The innovative ideas of entrepreneurs and scientists worldwide are demonstrating that agricultural waste can have immense value if managed properly. The pineapple case is just one of many examples showing how biomass can replace petroleum products in the production of energy, fertilizers, and materials.
Although these types of initiatives are still in their early stages, the construction of biorefineries represents a promising future for the development of renewable energies that will not only be technically viable, but also economically competitive.
In 2017, Bermúdez and Utgärd's idea to build a pineapple waste treatment plant became a reality, thanks to machinery that reduces the waste's moisture content. From now on, the production of biofuels and other byproducts from pineapple waste may expand to other parts of the world, helping to decarbonize the global economy.
Pineapple and other agricultural crops are emerging as key players in the global energy landscape, capable of reducing our dependence on oil and mitigating the environmental impact of agricultural waste.
