Equipment for Sanitary Landfill Operations in the Central Region of Coahuila

Status: Completed


In an effort to improve solid waste management in the central region of Coahuila, in April 1995, the steel mill, Altos Hornos de México, S.A.B. de C.V. (AHMSA) promoted the creation of Patronato Pro Limpieza, formed by the municipalities of Castaños, Frontera, Monclova, Nadadores, San Buenaventura and AHMSA. Under this scheme, AHMSA acts as the head
of Patronato Pro Limpieza and operates the regional landfill, controls the budget and maintains the vehicles used for landfill operations. Each municipality pays a monthly fee that all together covers 50% of the total cost of operating the landfill, and AHMSA provides the other 50%.

The regional landfill began operations in 1995 and complies with Mexican federal standard NOM-083 SEMARNAT-2003. It is expected to have a total of 16 cells with an overall useful life through 2035. Approximately 380 metric tons of waste are deposited in the landfill on a daily basis. Cell No. 9 will reach full capacity by the end of 2016. Cell No. 10 is currently
under construction, and the sponsor expects to initiate its operation by the end of 2016.

The sponsor owns heavy equipment and machinery for landfill operations, including a dump truck (1998 model) to move soil and cover waste, a towable water tank (1998 model) for dust control and to support compacting, a 816-F compactor (2006 model), a 938 G backhoe to move soil, and a D7R bulldozer (model 1998) to spread soil and waste prior to
compacting. The 1998 D7R bulldozer has already exceeded its expected useful life, requires constant repairs and jeopardizes proper solid waste management. Without the proposed equipment, the expected life of the landfill will be reduced and maintenance costs will increase.


The proposed project consists of the acquisition of a bulldozer, Caterpillar D7 or similar, with the following specifications: an enclosed cabin, low ground pressure (LGP) tracks for added stability and greater surface area for more efficient waste compaction, along with an extended blade to facilitate waste dispersion and to protect the machine from waste passing
over the top of the blade.


With the implementation of the project, the sponsor will continue to operate the landfill properly and in compliance with regulations, thus reducing potential environmental and human health risks related to the accumulation of improperly handled solid waste. Additionally, equipment acquisition strengthens the institutional capacity of Patronato Pro Limpieza and promotes sustainable development within the region, which will improve the quality of life in the area.
