HERA Group

Founded in the 90’s in Barcelona (Spain), the HERA Group is at present an
international business group, leader in the field of integrated waste
management and environmental resources, with its own facilities in Europe,
Latin America and a significant presence in Asia, Canada and the Middle East.
For more than two decades, the HERA Group has been steadily providing
integral and efficient environmental solutions to government
administrations, industry and the private sector. More than 5,000 companies
have placed their trust in our services.
The HERA Group regards waste not simply as disposable garbage, but as a
resource with a high recyclable and recovery potential, which allows us to
obtain new materials, energy, space, regenerated feedstock and biofuel.
The activities and environmental solutions presented here, are part of HERA
Group’s ultimate objective : to transform waste into a new resource.
