Adamant Group acquires majority stake in Milan biorefinery, forming strategic partnerships to expand sustainable biofuels production and circular feedstock processing.
Adamant Group has announced the acquisition of a majority stake in a biorefinery located in the Milan metropolitan area of Italy, marking a significant milestone in the company’s strategic expansion within the biofuels and renewable feedstocks sector. This move reinforces Adamant Group’s long-term commitment to building a robust industrial presence focused on the upgrading and valorisation of renewable, advanced, and circular raw materials that support the energy transition.
The transaction has been structured as a partnership involving two established players in complementary segments of the value chain. SAAR Depositi Portuali, a prominent Italian port infrastructure operator, joins the initiative by contributing its extensive logistics and storage expertise. SAAR manages coastal terminals in the ports of Genoa and Vado Ligure and offers a total storage capacity exceeding 350,000 cubic metres, positioning it as a key enabler of efficient feedstock handling and product distribution. Alongside SAAR, Medara Trading participates as a strategic partner, bringing deep market knowledge and trading capabilities across Europe. Medara Trading is particularly active in advanced feedstocks, finished biofuels, and associated products that serve renewable energy markets.
Together, Adamant Group and its partners aim to develop an industrial platform that is both efficient and scalable, designed to meet growing market demand while maintaining high operational reliability and stringent quality standards. The newly acquired operating company has been named Xanthos S.r.l., reflecting a fresh industrial identity aligned with sustainability and innovation.
The biorefinery operated by Xanthos S.r.l. has an estimated refining capacity of approximately 8,000 tonnes per month. It is equipped to carry out a wide range of industrial processes, including glycerolysis, acid washing, filtration, and physical distillation. This diversified technical configuration allows the plant to achieve a high degree of operational flexibility, enabling it to process different types of feedstocks and adapt to varying product specifications and customer requirements. Such versatility is particularly important in a market where feedstock availability and regulatory frameworks continue to evolve.
All feedstocks processed at the facility will be certified as sustainable and will primarily consist of residues and by-products rather than virgin raw materials. This approach ensures full circularity across the supply chain and delivers substantial environmental benefits. Compared with conventional fossil-based alternatives, the products generated at the biorefinery are expected to achieve carbon dioxide emission savings of more than 80%, supporting climate targets and regulatory compliance across European markets.
The refined oils produced by Xanthos S.r.l. will serve multiple end-use applications. These include co-processing in traditional petroleum refineries, supply of bio-bunker fuels for maritime customers in both the Mediterranean and Northern European regions, and use as feedstock for the production of hydrotreated vegetable oil (HVO) and advanced biodiesel.
Commenting on the transaction, Riccardo Marchetti, CEO of Adamant Group, stated that the acquisition represents another important step in the company’s growth trajectory and in the creation of an integrated industrial base that combines technical know-how with sourcing and logistics capabilities. He further noted that the collaboration with SAAR Depositi Portuali and Medara Trading strengthens an industrial ecosystem built around performance, reliability, and long-term development.
In the months ahead, Adamant Group and its partners plan to focus on fully enhancing the asset. Key priorities will include operational optimisation, improved process efficiency, increased automation, and the expansion of commercial activities. The start-up of the plant is currently scheduled for March 2026, positioning Xanthos S.r.l. to play a meaningful role in Europe’s evolving biofuels landscape.
