Project Partners Request: Okhla Landfill in Delhi, India

A preliminary assessment of the potential for a landfill gas (LFG) utilization or flaring only project was performed for the Okhla Landfill in Delhi, India (City) based on information provided by the City and observations made during a site visit on February 21, 2007.

The landfill opened in 1994, has approximately 5.6 million tones of waste in place, and is projected to close in 2008 after reaching a site capacity of about 6.3 million tonnes. A landfill gas (LFG) recovery model was prepared based on waste disposal, waste composition, and climate data. The model results indicated that LFG recovery is projected to reach a maximum of approximately 1,660 cubic meters per hour (m³/hour) in 2008 and decline after site closure.

Given the projected LFG recovery rate, a preliminary evaluation of available LFG project options indicates that a flaring, direct use, or electrical generation projects may be feasible for this site. Significant income streams from emissions trading of reduced greenhouse gas (GHG) emissions and from beneficial use project revenues are possible for this landfill. Nearby markets for the LFG exist and include a cement production facility and a hospital. An electrical substation is located adjacent to the landfill which can facilitate an LFGE project that would provide electricity to the local grid.

However, significant investment would be needed to construct a cap, grade the landfill, and install a gas collection and control system. The information and predictions contained within this assessment report are based on the data provided by the site owners and operators. Neither the U.S. EPA nor its contractors can take responsibility for the accuracy of this data. Assessments and predictions presented in this report are based on the data and physical conditions of the landfill observed at the time of the site visit. The landfill does not have a current gas collection, flaring or utilization system. The estimated capital, operational costs, and return on investment resulting from installing such a system at the site are based on current, typical costs in America, but no warranty is given or implied on the accuracy of these data.

Instead of allowing LFG to escape into the air, it can be captured, converted, and used as an energy source. Using LFG helps to reduce odors and other hazards associated with LFG emissions, and it helps prevent methane from migrating into the atmosphere and contributing to local smog and global climate change.

LFG project options are:

• on-site electricity generation;
• direct use for heating/boiler fuel (medium-Btu application)
• flaring only.

All three options would require some level of grading work, capping of the landfill, and installation of an active gas collection and control system (GCCS), including a flare to ensure combustion of all collected LFG when the methane is not being utilized. All three options also are expected to generate revenues from the sale of emission reduction credits.
