Solid Waste

Last updated Nov 25, 2014

At the end of 2001, the generation of solid waste, hazardous and non-hazardous, in 2011 was of 129,987.1 tons, which is 23.3% less than that generated in 2010, due to the increase in recycling activities. 

Generation of Solid Waste (Tons)
2009 108,464.3 83,853.2 192,317.6
2010 117,494.8 52,118.7 169,613.7
2011 93,028.96 36,958.14 129,987.10

Production and Refining are the areas that generate the greatest amount of hazardous waste, and the volumes are comprised of the following waste: Oil-impregnated items (rags, cloths, stuffing, gloves, paper, absorbent materials and filter cartridges etc.), clays, sands, oil-impregnated catalysts, tank sludge, ceramic balls (Ceramic material, catalysts or other toxic substances), and waste resulting from the production or processing of oil and asphalt. 

Through the work carried out with third parties, 20% of hazardous waste generated was treated through bioremediation and incineration, and 34.3% was leveraged through reuse or recycling.

Note: The data reported here corresponds to the internal work carried out by Ecopetrol as a generator and through third parties for the management of hazardous waste, following the provisions of Decree 4741 of 2005. 

Non-hazardous waste generation was 20.8% lower compared to 2010. Of this total by 1% is managed through utilization (recycling, reuse, etc.) and 8% is taken to a landfill or dump. 

The majority of non-hazardous waste generated is: Rubble, scrap metal and organic. 

Comprehensive management of hazardous waste 

In 2011, initially the Supply Department and later the Shared Services Department of Ecopetrol, continued to develop strategies to optimize the disposal of Materials and Assets not Required for the Operation of the company and for their use, either by Ecopetrol or third parties, in a manner aligned with the legal system, obtaining economic benefits and generating sustainable development (mitigating environmental impact or generating social well-being), and with potential benefits in corporate reputation and image. The following figures are a result of this work:

Additionally, in 2011, Reverse Logistics continued to support generation areas in waste disposal, providing technical specifications, budgets, market intelligence and external audits, which made it possible to support the different contracting processes taken forward by the businesses for the carrying out of industrial waste disposal, such as transformers with PCBs> 50ppm, oil-impregnated waste, and fluorescent lamps. Work was done in conjunction with the Environmental Management Unit of the HSE Department´s for budget planning, and the review of specifications that will serve to support the characterization and subsequent disposal of unknown chemical waste.
