Figure 1.
Relationship between the 2010 California waste in place (WIP) (x 106 Mg) and the annual landfill biogas recovery (252 × 10-6 Nm3 LFG hr-1Mg-1 or 126 Nm3 CH4 hr-1Mg-1) from the California database (Walker et al., 2012).
This figure illustrates the comparison between the total waste in-place at 128 California landfills to annual average landfill gas recovery rates which has been normalized to 50% CH4. Despite the variety of individual landfill sites, there is a statistically significant correlation between all the sites (P<0.001), which allows an estimate of the average biogas recovery rate for all landfill sites in California.
