Sanitary landfills

Sanitary landfills represent significant engineering and environmental challenges. Despite efforts towards a circular economy, in many countries a significant fraction of waste is still sent to landfills, making it crucial for the environment and populations that landfills are stable, under control, and their capacity is maximized.

We have extensive experience in the various stages of large and small sanitary landfills. We have developed methodologies to optimize the location of new landfills with different criteria, we install and monitor instrumentation, perform geophysical exploration, including geoelectric testing, and have developed the performance concept that models the behavior of landfills in the long term and optimizes their capacity. We have also designed all the necessary works for their installation and operation. In addition, we have diagnosed existing landfills and designed practical measures for their control and expansion.

For years, we have been the technical advisors for waste management service companies. The design of disposal programs is an integral part of the technical support we provide, so we adapt solid waste disposal tasks to demand and optimized investment plans. We are capable of conducting environmental impact studies, considering both the civil and environmental components.

Projects

We have had the opportunity to participate in studies and designs of sanitary landfills of different scales, ranging from those that serve the needs of small municipalities such as Yarumal and La Ceja, sin the North and East subregions of the department of Antioquia, respectively. For medium-scale projects, we can mention the Blue Lizard Sanitary Landfill, which serves the islands of Providencia and Santa Catalina, in the north of Colombia. For large-scale projects, there is the La Pradera Sanitary Landfill, located in the North subregion of the department of Antioquia, which currently serves about 43 municipalities in total, including the city of Medellín and the Metropolitan Area of the Aburrá Valley.
