1. Landfilling of 1 kg of food waste results in emissions of approximately 0.017 kg of non-fossil CH₂ (methane). a. Calculate the carbon dioxide equivalents using the global warming potential in

the 20-, 100- and 500-year time horizon. Calculate the carbon dioxide equivalents using the global temperature potential in the 50- and 100-year time horizon. b. Plot these on a graph Species CO CH.-fessil CH-on fossil NO WC-32 HFC-134 CFC-11 PFC-14 Radiative GWP-20 GWF-100 GWP-500 GTF-50 GTP-100 Efficiency (W¹ppb) 1.3301610¹ 1 1.000 1.000 1.000 1.000 5.7 1.4x10 82.5258 29311 16.034 13.26.1 75.29 118x18 5.7 1.4x10 797258 27.011 72=38 10.461 47629 109 10 2.81.1x10 273118 273130 13064 390 140 233110 54:11 1.10.2x10 2013042 771292 220 87 14051 78,17529,402 12,000 36,534 14.0 28 1.57032x10 41441150 1526577 436 173 733410 306119 146,67953.318 181,40871,365 52.0 10.4 2.91 0.65×10 83213419 62262297 2098865 6351 2342 35361511 9.39 0.19×10 53011395 73802430 10,5873632 76602464 9055 3128 18183 Lifetime (Years) Multiple CGTP-50 (years) 28231000 2675 a 1057 CGTP-100 35311385 Emission metrics for selected species: Global Warming Potential (GWP), Global Temperature-change Potential (GTP).
