LANDFILL BIOGAS PROJECT OPPORTUNITY

LOJA LANDFILL

OVERVIEW OF LANDFILL BIOGAS PROJECT OPPORTUNITY:

Loja Landfill is a controlled landfill owned and operated by the municipality of Loja. Loja Landfill

LOJA LANDFILL LOJA, LOJA PROVINCE, ECUADOR

operated by the municipality of Loja. Loja Landfill accepts domestic and commercial waste from the city of Loja and the surrounding area.

• The site opened in 1997 and accepts approximately 30,000 tonnes of waste annually.

• As of August 2006, the site contained 292,978 tonnes of waste.Th l dfill i t d t l i 2015 ith• The landfill is expected to close in 2015 with an estimated capacity of 750,000 tonnes of waste.

• Preliminary biogas modeling estimates that 127 m3/hr of biogas at 50% methane is currently recoverable for capture and use.

• Biogas recovery will rise to a peak of approximately 261 m3/hr shortly after closure in 2017, provided that the landfill continues to2017, provided that the landfill continues to expand.

The municipality of Loja seeks specific cooperation to advance the development of this project:

• The municipality seeks technical assistance and a partner to develop a project

ENVIRONMENTAL BENEFITS

• The project is willing to consider carbon financing

• The project owner does not have a contract to sell its carbon credits

PROJECT OPTIONS

Loja Landfill provides a good opportunity for a small heat or co-generation project with an initial electrical output of 200 kW rising to nearly 450 kW in the next 10 years. The site is producing moderate quantities of methane that could be utilized for economically

• Estimated annual waste acceptance rates for 2007 to 2017: 34,000 to 57,000 tonnes/year y

feasible onsite power generation using a spark ignition engine. An option also exists for the use of landfill gas as a fuel for medical waste incineration. Note that for this purpose, a secondary combustion process, using conventional fuels, may be required for compliance with emission standards in Ecuador.

As of December 2009, the landfill is installing an incinerator and is interested in obtaining technical

tonnes/year• Waste disposal area: 2.25 hectares• Current depth of waste: approximately 20 meters• Liner: plastic liner overlaying natural soils • Cap: since the site is still active, no permanent cap exists; daily cover is a mix of gravel and clay

Several passive gas vents were on fire at the time of a site visit in 2006. Fires present asignificant hazard to health and the existingtechniques for extinguishing landfill fires should beinvestigated. The elimination of fires would allow forthe installation and operation of a landfill gas
