In terms of climate change adaptation, the study also highlighted the need to first address the issue of leachate collection, since too much leachate makes it impossible to collect biogas ( and furthermore to recover it as energy), even though the equipment is operational and of good quality.

CONCLUSION
AND HIGHLIGHTS
Thanks to the CICLIA-funded study, the project team was able to confirm the feasibility of increasing waste storage on the Aképé site and, more importantly, to quantify the major environmental and economic benefits of upgrading it to biogas in order to produce low-carbon electricity.
Controlling the amount of leachate was identified as a prerequisite for transforming a polluting site into a renewable electricity producer.

1. The general objectives of the support
Assessed the carbon footprint (greenhouse gas emissions) of increasing the waste storage capacity of the TLC,
Analysed the potential of electrical recovery of biogas (contributing to the reduction of GHG emissions) and studying the opportunity of deploying the associated installations,
Defined the conditions for improving leachate treatment capacities, a prerequisite for biogas capture,
Assessed the feasibility of installing solar panels on the former Greater Lomé landfill site in Agoè-Nyivé.

The Greater Lomé Autonomous District (DAGL) is responsible for waste management within its administrative perimeter: pre-collection, collection, storage, waste treatment (including recovery) and street cleaning. For collection, processing and street cleaning, companies are paid according to the services provided for in their contracts, under the control of the waste management division.
In the end, Lomé benefits from a structured "solid waste" sector, quality infrastructures and a management mode contracted out to the private sector.

Lomé, the capital of Togo, is a fast-growing city. The Lomé agglomeration (the "Greater Lomé") has more than 1.7 million inhabitants in 2015, i.e. 25% of the country's inhabitants. Annual waste production in Greater Lomé is around 305,340 tons. In total, almost 90,000 tons of waste are collected and buried, i.e. a collection rate of 29%. 9,000 tons of waste are recovered in compost by associations and NGOs.
Since 2007, Lomé has thoroughly restructured its waste management service within the framework of the Lomé Urban Environment Project (PEUL, components I, II, III and IV) with AFD funding.

Greater Lomé and the historical local operator of the Technical Landfill Centre (TLC) have requested CICLIA, via AFD, to provide support and proposals to continue to improve waste treatment and particularly the operating of the Aképé TLC. The improvement of the TLC's performance is made essential by, on the one hand, the quantitative evolution of waste production in the agglomeration, and on the other hand, the sector's responsibility in the country's carbon footprint (4.5% of national emissions in 2020). Furthermore, in terms of adaptation to climate change, the TLC site must be adapted to changes in the rainfall pattern. Rainfall is becoming increasingly violent and condensed, causing flooding that block access, and generating larger than expected quantities of leachate1 at certain times.
