Introduction
The transition to more sustainable agriculture involves innovation in CO₂ management for greenhouses. Green Gas & Liquids, a Dutch company, offers a carbon capture technology, Galloxol®, which allows crops to be enriched with CO₂ without liquefaction, thereby reducing costs and environmental impact.
Galloxol®: a direct and clean capture technology
The Galloxol® platform captures CO₂ from biomass boilers and delivers it directly in gaseous form, ready to be injected into greenhouses. Unlike traditional amine-based systems, which require a costly and energy-intensive liquefaction step to achieve the required purity, Galloxol® eliminates this need. The captured gas has been analyzed according to the strict specifications of the ISBT (International Society of Beverage Technologists) and has met these standards, demonstrating the cleanliness of the process.
“ISBT is not a horticultural standard, but a specification for beverages, much stricter on most parameters. This shows how few impurities the Galloxol® process adds to the captured gas.” — Nicola Donato, Green Gas & Liquids
Safety, simplicity, and sustainability
The core of the process relies on a safe and biodegradable solvent, unlike conventional amines which pose toxicity and waste management challenges. This innovation reduces chemical risks for operators and crops, while simplifying regulatory compliance.
A more accessible economic model
By eliminating liquefaction, Galloxol® reduces initial investment (Capex) and operating costs (Opex). The absence of compressors and refrigeration systems reduces maintenance and electricity consumption, making dedicated CO₂ capture accessible to more farms, even small ones.
Deployment and prospects
Since 2019, four Galloxol® installations are already operating in the Netherlands, Italy, and Austria, in the horticulture and biogas sectors. For producers, the combination of local, sustainable, safe, and economical CO₂ represents a credible alternative to conventional supplies.
Conclusion: Opportunities for WasteOlas
The Galloxol® approach illustrates a major trend: local decarbonization and process simplification for greenhouse agriculture. For WasteOlas, this type of solution opens the way for strategic partnerships with innovative players, while validating the feasibility of clean and competitive CO₂ for the sector. The future of agricultural CO₂ will be local, sustainable, and optimized.
