Colombian capital Bogotá's public services department (UAESP) has received 13 bids for a tender to concession waste management services in six zones of the capital for the next eight years.
The concession, which is worth some 2.5tn pesos (US$1.41bn), is scheduled to be awarded August 19, UAESP said in a release.
Among the bidders were local firm Aseo Triple A, the KMA Insun-Contelac group, a consortium led by Conconcreto and ten other groups.
The Oesa group withdrew its bid because it had only provided two of the three envelopes needed for the tender, according to local reports.
The concession involves modernizing the waste collection system and improving recycling and is expected to reduce garbage collection rates by 19% on average.
The concession process proceeded after a ruling by the district court dismissing allegations that the tender process had violated due process by excluding the recycling sector from participating.
