Dower Law Firm advises C2 Capital Partners on its acquisition of a stake in Adventech

Dower Law Firm advised C2 Capital Partners on its investment in Adventech through a €3 million transaction in a Portuguese company specializing in technological solutions for the treatment of industrial wastewater and gaseous effluents.

The transaction will enable Adventech to accelerate its growth strategy, strengthen its research and development capabilities, and consolidate its position in the Portuguese market for the treatment of highly complex industrial effluents.

Founded in 2008, Adventech develops integrated environmental engineering solutions, covering the entire value chain—from laboratory characterization and pilot testing to the engineering, construction, and operation of treatment facilities. The company operates in highly regulated sectors, including pharmaceuticals, chemicals, petrochemicals, and agribusiness.

C2 Capital Partners’ investment is intended to support three strategic priorities: consolidating Adventech’s leadership position in Portugal, strengthening its management structure and specialized technical teams, and establishing a new research and development laboratory to accelerate technological innovation.

The legal advisory work on the transaction was carried out by Dower Law Firm’s team led by Eduardo Castro Marques, Partner in the Corporate and M&A practice, with the support of associates Cláudia Rodrigues Carvalho and Francisco Duarte Rodrigues. The team advised on all stages of the transaction, from structuring through to the implementation of the investment.

“The entry of C2 Capital Partners into Adventech’s share capital required the structuring and negotiation of a range of legal solutions designed to accommodate the strategic objectives of all parties involved, while ensuring the conditions necessary for the company’s future growth. The technical complexity of the sector and the strategic relevance of the investment made this a particularly interesting transaction for our team,” said Eduardo Castro Marques.

The transaction reflects the growing importance of investments in environmental technologies and sustainable industrial solutions, as well as the dynamism of the Portuguese venture capital market in fostering innovation and supporting the sustainable transition.
