Background
The regional landfill is operated in compliance with Mexican laws by Patronato Pro-Limpieza, a nonprofit organization formed by the municipalities of Castaños, Frontera, Monclova, Nadadores, San Buenaventura and AHMSA. It began operations in 1995 and is expected to have a total of 16 cells with an overall useful life through 2035. In 2016, approximately 380 metric tons of waste was deposited in the landfill on a daily basis. Cell No. 9 was expected to reach full capacity by the end of the year, and Cell No. 10 was under_construction. The sponsor owns heavy equipment and machinery for landfill operations, including a D7R bulldozer (model 1998) to spread soil and waste prior to compacting. Its bulldozer had exceeded its expected useful life, required constant repairs and jeopardized proper solid waste management. Without the proposed equipment, the expected life of the landfill would be reduced, and maintenance costs would increase.
Project Scope
The project consisted of the acquisition of a bulldozer, Caterpillar D7 or similar.
Benefits
The new equipment allowed the sponsor to continue operating the landfill properly and in compliance with regulations, thus reducing potential environmental and human health risks related to inadequate solid waste disposal. In particular, the landfill is disposing of approximately 420 metric tons/day of waste and serves an estimated 107,835 households in the five municipalities.
