When planning a new landfill, a new section or an extension of a landfill, the landfill operator is faced with the decision on the type of implementation. After all, considerable financial security must be provided for the operation and long-term aftercare of a landfill site. One possibility is the PP-LANDFILL model as a cooperation between public and private partners. The model is also referred to as prepaid landfill because, as a private partner, we provide the financial investments starting from the landfill planning phase up until the aftercare phase. This way, cooperation with a strong partner such as REMEX promises to ease the burden on municipal budgets and fee payers.
