The ZhanaSolutions – Fondo Acción partnership will scale the collection and processing of brown grease from industrial kitchens in Colombia to make it suitable for biodiesel production. This solution valorizes cooking waste, prevents water contamination, and applies circular economy principles in the production of alternate energy sources.
P4G has awarded the partnership with US $359,000 in grant funding.
At the core of ZhanaSolutions’ business is the G-Trap unit. This equipment employs technology that separates up to 99% of oils and fats from wastewater collected in industrial kitchens. This brown grease is further processed at collection centers and then transported to a final conditioning site where it is purified to meet the necessary standard to become raw material for biodiesel production.
Zhana has two primary sources of income. One from a monthly fee for providing grease waste management services to food retail companies such as Frisby, Éxito, Crepes y Waffles, KFC and Hyatt Hotels. The second source is from the sale of purified brown grease to biodiesel producers.
Zhana plans to include sensors in its equipment that will allow the business to share impact indicators with its clients such as the amount of waste repurposed and liters of water saved from contamination.
With the growing need for alternate cleaner sources of energy, Zhana provides a cost-effective solution for meeting the demand for used cooking oil to aid biofuel production while also contributing to wastewater management.
The partnership hopes to provide recommendations that can inform and update the existing discharge regulatory framework in Colombia to ensure that more companies manage their brown grease responsibly.
Fondo Acción is a private Colombian fund with 23 years of experience in sustainable investments in environment and childhood solutions. In 2018, Fondo’s Impact Investment Fund (FIMI, for its name in Spanish) launched to support entrepreneurs concerned with the planet’s health and with social equity.
Fondo Acción is supporting Zhana pursue the enabling environment interventions that will incentivize industrial kitchens to better wastewater treating practices. It is also leading on producing case studies and policy briefs aimed at sharing learning with other similar actors in the brown grease collection and wastewater processing industry.
Between April and September 2024, Zhana produced 40 G-Trap units, deploying nine across Zhana Zones in Bogotá, Cartagena and Medellín. Zhana also hired an administrative coordinator for its project.
Zhana attended and presented at several events, including innPact Week in Barranquilla and the Fundación Grupo Bancolombia EnCampo Bootcamp. It showcased its technology at Alimentec, one of the biggest food industry fairs in Colombia, generating 427 qualified leads with 166 showing purchase interest. It launched a pilot with Arcos Dorados (McDonald’s) in Argentina and is setting up a pilot with Grupo Nutresa (Hamburguesas El Corral) in Bogotá. Zhana also gained valuable connections with stakeholders like Bogotá's Environmental Secretary and Cali’s Chamber of Commerce.
At San Francisco Climate Week, Zhana engaged with climate tech investors and Cleantech San Diego. The partnership also participated in key events on sustainable economy and climate financing and held meetings with notable companies.
Lastly, Zhana set up its data room and presented it to its investment committee. The next steps involve finalizing its company valuation and launching its Series A campaign.
Between October 2024 and March 2025, Zhana installed 27 new units in Bogotá, Cartagena, Cali and Medellín. Notably, pilots with major brands Arcos Dorados and Nutresa resulted in expansion requests. These partnerships signal growing demand from top food service brands for Zhana’s sustainable waste treatment solution.
Zhana hosted an official COP16 Biodiversity Conference side event in Cali, positioning its model as a leading circular solution for sustainable cities. The event featured leaders from government and business, including the former Environment Minister and top executives from Frisby and COTELCO. Zhana was also featured in a national TV interview on Primer Plano, further increasing public visibility.
The team deepened relationships with municipal utilities and industry guilds. In Cartagena, Zhana launched alliances with business associations COTELCO, ACODRES and FENALCO to scale adoption among 83 hotels and leading restaurants. In Bogotá and Barranquilla, formal agreements were structured with city sewage companies to provide technical support and sponsorship for service expansion.
Zhana hosted two major technical roundtables in Cartagena, convening public and private stakeholders to address waste management challenges and advance sustainable tourism. The discussions led to proposals for regulatory reforms, operational improvements and the launch of a green certification seal for restaurants and hotels. These dialogues mark a key step in Zhana’s effort to institutionalize circular practices at the city level.
Zhana also participated in high-profile industry events, generating 205 new leads through exhibitions in Bogotá, Medellín and Cartagena. At the 2025 Latin American Impact Investing Forum, Zhana met with over 15 investors, securing intent from multiple Latin American-based impact funds to lead its Series A round with commitments totaling up to US $3 million. This interest reflects strong investor confidence in Zhana’s scalable impact model.
During the P4G funding period, the partnership aims to raise around US $1.8 million in investment, create 20 additional jobs, and reduce around 448 metric tons of carbon emissions. It also aims to increase the number of service sites from 192 in 2023 to about 2,000 by the end of 2025.
The partnership comprises the following partners: ZhanaSolutions (lead business partners); Fondo Acción (lead administrative partner).
