Hera Group acquires Ambiente Energia and achieves further growth in the Northeast
22/07/2025
After the binding agreement reached in February, the subsidiary Herambiente Servizi Industriali completes the acquisition of Ambiente Energia, based in Schio in Vicenza, from the Marzotto Group. This transaction further expands the offer of waste recovery and treatment services to companies in one of the most productive areas of the country

This morning in Bologna, the subsidiary Herambiente Servizi Industriali finalised the acquisition, from Manifattura Lane Gaetano Marzotto & Figli, of 100% of the capital of Ambiente Energia, a company operating in liquid industrial waste treatment at its plant in Schio, near Vicenza. This closing concludes the process that began on 27 February, when a binding agreement was signed by the two companies.
Transaction in line with the 2028 Business Plan
The Hera Group thus continues its growth in the North-East, in waste treatment and recovery in particular, fully consistent with its 2028 Business Plan, which sees vertical integrations as an important lever for further expansion and diversification of its plant base, with positive impacts on profitability and market share.
More specifically, Ambiente Energia will extend Herambiente Servizi Industriali global waste management offer in one of the most productive and dynamic areas of the country, where the Hera Group is already established with its subsidiaries Vallortigara Servizi Ambientali with two plants in Vicenza province, Aliplast in the Treviso area and Recycla with two plants in Treviso and Podernone.
A multi-purpose plant with an annual capacity of over 120,000 tonnes
Ambiente Energia plant, with an annual capacity of more than 120,000 tonnes, thanks to state-of-the-art technological equipment, treats numerous types of liquid and sludge waste, both hazardous and non-hazardous, such as, for example, water from painting and washing, acids and bases, and water from chemical-physical treatments. Its services are thus completely designed for the industrial districts of the Veneto region, including the textile, tanning, engineering and eyewear industries. The purification plant, which returns water to surface waters after treatment, has 41 storage tanks, a wastewater treatment line (both chemical-physical and biological) and a sludge treatment line.
This capacity will allow for greater flexibility and volume while constructing the waste management and recovery projects proposed by Herambiente Servizi Industriali to local companies. As for Ambiente Energia’s existing customers, they will gain access to the know-how of Herambiente and its subsidiaries in developing resource valorisation and circular economy projects, with a focus on the treatment of liquid and sludge waste.
Full employment continuity for Ambiente Energia resources
As was confirmed when the binding agreement was signed, the transaction foresees the retention of all of Ambiente Energia current employees, guaranteeing full employment continuity protecting the company’s technical-operational assets for the benefit of its customers.
“We are very pleased with this further growth we have achieved,” explains Herambiente CEO Andrea Ramonda. “This acquisition not only consolidates Herambiente’s already vast set of plants, but also further broadens the customer base in environmental services, with positive spin-offs on cross-selling opportunities, which will also benefit from synergies with the neighbouring Vallortigara Servizi Ambientali, already part of the Hera Group”.
