Watch: Innovative techniques used to maximise current landfill capacity

A new project on the Għallis landfill will see its capacity maximised through vertical expansion without increasing its footprint or taking up more land. 

Visiting the site, Minister for the Environment, Climate Change and Planning Aaron Farrugia saidthat this unique patented technique that is being used will not require any new infrastructure or facilities to be built and is thus an environmentally friendly way of increasing the capacity whilst maintaining the original footprint.

It consists of the construction of a retaining wall structure made from the same waste that is currently being disposed of in the landfill. By constructing the wall at a 70-degree slope instead of the typical landfill slope of 30 degrees, the landfill capacity will increase by 330,000m3 which is 130 times bigger than an Olympic-sized pool. 

Minister Farrugia said that this method will optimise landfill management with the purpose of increasing the landfill lifespan, allowing Malta to make the most of the current landfill space until the waste-to-energy plant is built. This plant will allow Malta to move away from landfilling by converting waste that cannot be recycled into green energy, while Malta continues to improve its performance and moves towards its targets for recyclables. 

WasteServ CEO Richard Bilocca explained that this impressive engineering and architectural venture comes with a patented design due to its unique incline that will save on landfill space. Once completed, the wall will be around 667 meters long constructed out of 315,000 tonnes of waste, the equivalent of the amount of waste generated in one year.
