EC Waste owns and operates El Coquí Landfill at Humacao. Its construction and operation are under the strictest standards of the solid waste industry in Puerto Rico and U.S. The Subtitle D of the Environmental Protection Agency (EPA, 40CFR 258) oversees the operation of sanitary landfills under the Resource Conservation and Recovery Act (RCRA). The EPA, as authorized by RCRA, delegated the regulation of non-hazardous solid wastes under Subtitle D to the Puerto Rico Environmental Quality Board (EQB) and the Regulation for the Management of Non-Hazardous Solid Wastes.


El Coquí Landfill meets all the requirements of Subtitle D of RCRA and EQB. Some of these requirements are the use of synthetic liners, leachate collection, gas collection and management, rainwater management, environmental monitoring and others.


The EC Waste sanitary landfills have closure plans approved by the EQB and in compliance with Subtitle D of RCRA. These rules require covering a sanitary landfill that completes its useful life with a synthetic liner and to manage leachates and gases for at least 30 years, in addition to maintaining the areas under the previous operation. El Coquí Landfill has the financial resources required by law to guarantee the closure and maintenance after the closing, with private funds and without causing a burden to the people of Puerto Rico.


EC Waste Sanitary landfills offer long term efficient, trustworthy and safe option to manage non-hazardous solid wastes in Puerto Rico, for several decades. Our commitment to the environment and Puerto Rico guarantees a long-term operation without consequences for taxpayers. No other sanitary landfill meets the financial guarantees required by regulations; those that do not comply with closure plans and financial assurance will become a burden to taxpayers.

What is the purpose of a landfill?

The purpose of a landfill is to provide an effective way to dispose of waste material. Landfills are designed and operated under environmental regulations, providing a safe and efficient way to dispose of solid waste materials.

When properly managed, landfills can protect communities from potential contamination and help preserve scarce resources by reducing emissions and protecting surface and groundwater resources.

How do landfills work?

Landfills are typically constructed in layers, with each layer consisting of a protective liner and waste materials. The top layer consists of soil or non-degradable materials such as plastic to ensure that the contents remain contained within the landfill.

As additional waste is added to the landfill, it is compacted into a dense form and covered with soil or non-degradable cover material. This helps to minimize the release of odors and prevent the entry of pests into the landfill site. Additionally, leachate collection systems are installed to capture liquids that the decomposing waste materials may generate.

This liquid is then treated before being released back into the environment. Landfill gas-to-energy systems are also installed in some landfills to capture and convert the methane gas from decomposing waste into electricity.

As landfills reach capacity, they are typically closed off and monitored for environmental compliance before being rehabilitated or covered with soil. By taking these steps, communities can ensure that their landfills are effectively managed and do not threaten the environment.

What happens to the waste in a landfill?

The waste materials deposited into landfills undergo a process of decomposition over time. This process is known as biodegradation, which occurs as bacteria and other microorganisms break down the materials in the landfill.

As the materials decompose, they are converted into nutrient-rich soil that can be used for landscaping or landfill rehabilitation. Additionally, landfill gas-to-energy systems capture methane gas generated through this process and convert it into renewable energy.

By taking these steps, landfill operators can help ensure that landfill contents are managed responsibly and do not threaten the environment.

What kind of safety measures are taken at landfill sites?

Landfill sites are designed with special safety measures to protect the environment and nearby communities from potential health risks associated with landfill waste. These measures include landfill liners and leachate collection systems to prevent landfill waste from contaminating nearby soil and water.

Additionally, landfill gas-to-energy systems are typically installed in some landfills to capture and convert the methane gas from decomposing waste into electricity. Finally, landfill sites may also employ safety systems such as odor control, landfill compaction equipment, landfill covers, and landfill monitoring systems to ensure that landfill sites are managed responsibly.

By taking these steps, landfill operators can help protect the environment and nearby communities from potential health risks associated with landfill waste.
