Exclusive Partnership
in the Glass Industry
Giammarco Technologies, formerly recognized as Giammarco-Vetrocoke, was founded in 1955 in Venice, Italy. The company traces its origins back to the visionary merging of two major production facilities: a glasswork and a coking plant, orchestrated by Senator Giovanni Agnelli in 1924. This fusion gave birth to Vetrocoke.
The increased availability of coke oven gas led to the establishment of Vetrocoke Azotati in 1937, focusing on the production of synthetic Ammonia (NH3), an intermediate compound crucial for nitrogen-based fertilizers. This was achieved by harnessing the hydrogen (H2) content in coke oven gas.
In 1939, on the eve of World War II, Giuseppe Giammarco was appointed as the director of Vetrocoke Azotati. In the post-war period, he undertook the daunting task of reconstructing heavily damaged production facilities following seven significant aerial bombardments.
Giuseppe Giammarco, a brilliant and inventive mind, discovered the properties of certain substances known as activators that significantly enhanced the absorption and removal of CO2 from the synthesis gas mixture used in NH3 production. This discovery revolutionized the industry’s technology, leading to the development of highly simplified and reliable CO2 absorption/removal plants. These innovations were initially implemented at the Vetrocoke Azotati plant in Porto Marghera.
In 1955, Giuseppe Giammarco founded the formerly known Giammarco-Vetrocoke (GV) to further industrialize the patents related to CO2 absorption/removal processes. Since then, our proprietary processes have been awarded 19 international patents, serving as the foundation for constructing over 400 installations across the globe, with notable prevalence in Europe, India, and Russia.
In 1975, the Company embarked on a transformative phase by welcoming two eminent figures, Paolo Giammarco and Luigi Tomasi. Their arrival marked a pivotal era, consolidating the Company’s standing and propelling its expansion endeavours. Their technical prowess was instrumental in project development, where they pioneered the initial formulation of a comprehensive Process Design Package (PDP). Their substantial contributions to research and development resulted in the issuance of numerous patents on a global scale.
In 2013, the Firm embarked on a pioneering venture, partnering with Marchi Industriale to establish Green Methane (GM). With GM’s development of an exclusive and established technology, enabling the upgrading of Biogas into Biomethane, this strategic partnership laid the cornerstone for pioneering advancements in the renewable energy sector. Green Methane swiftly emerged as a frontrunner, culminating in its sale and integration into the Rosetti Marino Group in 2021. Over its lifespan, GM has built nearly 20 plants based on our proprietary processes.
In 2021, the Firm welcomed the third generation of the Giammarco family, with Giuseppe Giammarco at the helm. This marked a key milestone as the Company set out to expand its technological prowess beyond its established domains.
In 2025, the Company, formerly known as Giammarco-Vetrocoke, became Giammarco Technologies (GT), reflecting its strengthened commitment to sustainability, innovation, and global presence to meet the industry’s evolving needs. With a vision to advance post-combustion Carbon Capture, Utilization, and Storage (CCUS) across a wider range of industries including Biomass gasification, W2E, Cement, Glass, Pulp & Paper and Steel, Giammarco Technologies remains unwaveringly dedicated to fulfilling its pivotal role in the energy transition. These strategic steps are a testament to the company’s enduring dedication to its responsibilities, leveraging its core competencies to forge a sustainable path forward.
Even after more than 70 years, the GT process continues to stand as one of the three prominent global methods within the specialized industrial realm of CO2 absorption/removal from gases. At Giammarco Technologies, we honour our legacy while actively shaping a greener future through our dedication to innovative CO2 capture technologies.
