A novel green technology for a safe and eco-friendly long-term slope landfill aftercare

 

Sardinia 2021: 18th international symposium on waste management and sustainable landfilling

ABSTRACT:

Long-term slope landfills pose nowadays a serious social, ecological and economical problem. Long-term landfill management issues are problematic when durability and stability are not guaranteed. In the last decades, much attention has been devoted to the so-called Nature Based Solutions (NBSs), but these solutions often turn out to be problematic as traditional plant species are not strong enough to survive in hard climate conditions, sterile and/or contaminated soils. Among the NBSs for long-term aftercare, the Deep Rooting Plant solution, DRP, proposed by Prati Armati®, allows to operate in any condition. The present work promotes this innovative strategy, showing the benefits provided in terms of capability to grow, environmental impact and economic point of view with respect to different solutions traditionally considered for the application in long-term slope landfill aftercare.

CONCLUSIONS:

The numerous benefits deriving from the application of the innovative technology proposed with respect to traditional more common approaches have been discussed, namely the reduction in pollutant emissions, the positive impact on slope stability, the significant decrease in cost estimation.
Finally, both solutions, traditional solution with mineral liners and the solution with geosynthetic liners, need recurring and demanding aftercare maintenance, which adds both economic and environmental costs. Such maintenance is not required when adopting the solution with deep rooting plants, which is a rather self-repairing intervention, allowing for a recovery of the naturalistic landscape.
