Spanish infrastructure developer ACS Group has plans to sell its environmental subsidiary, Urbaser, which provides waste management and treatment services.

According to sources, ACS has hired BBVA and Societe Generale as financial advisors to conduct the transaction.

According to sources, the environmental company could has an estimated value of between €2 billion (US$2.18 billion) and €2.5 billion (US$2.73 billion). In 2014, Urbaser had a turnover of €1.65 billion (US$1.8 billion), which represents an increased of 8.3% from 2013, and its portfolio of contracts amounted €8.45 billion (US$9.23 billion).

This is not the first time that ACS aims to sell Urbaser. In 2008, ACS tried to sell the company to use the funds to reduce 50 % of the Group's debt. ACS has, as of September 2015, a total debt of approximately €3.9 billion (US$4.25 billion).
