MS-275 Compared to the total energy potential of waste
Compared to the total MS-275 potential of waste of 1125 PJ in 2012, about 283 PJ could be recovered from the LFG from landfills in the whole African continent, if all waste from urban areas is collected. From the total 2198 PJ of waste expected to be generated in 2025, around 530 PJ can be recovered from the LFG from landfills, also assuming a complete collection of generated waste. Considering the total energy potential of waste actually collected of 613 PJ in 2012, only about 155 PJ could be recovered from the LFG from landfills and from the overall 1508 PJ of waste generated in 2025, 363 PJ could be recovered from the LFG from landfills. The data shows large variations between countries, depending on the waste generation and waste collection rates as well, which have a large impact on the waste potentially available for energy. Moreover, electron needs to be pointed out that these results depend on the future options applied to waste management in Africa (reducing, recycling, reusing, composting, etc.) and to an extent to which the collection rates could increase, an aspect for which a simple “business as usual” approach is taken in this study.
