Ardian, a France-based, independent private equity investment company, agreed to acquire Attero, one of the largest waste treatment and recycling companies in the Netherlands, from 3i, a British multinational private equity and venture capital company, and DWS, a German asset management company, for €1.5bn. "Attero has been a most successful investment for the Company, experiencing substantial growth during our investment period. Whilst 3i Infrastructure aims to hold its investments over the longer term, we will sell investments where this generates significant additional value for our shareholders," Richard Laing, 3i Infrastructure Chair.
