Closed Landfills – Ecotoxicology and Environmental Safety

Poor landfill planning results in the proliferation of uncontrolled landfills and the existence of a considerable number of closed landfills that continue to pollute and endanger the environment and human health.

Different toxicological assessments of closed landfills show the effect that they have on neighbouring ecosystems.
For instance, landfill leachates entering water bodies are becoming one of the main factors of pollution of the aquatic environment. Rivers, seas, drainage canals, ponds and streams.

Water sampling and bioassay testing of rivers, seas, drainage channels, ponds and streams show a clear correlation between water quality and distance from closed landfill sites.

Landfills are associated with negative effects on the environment and human health, as they cause soil and groundwater contamination. What we often do not realise is that even landfills that have been closed for many years release leachates that often contain inorganic and persistent organic pollutants that are not biodegradable. Persistent pollutants are more dangerous because they migrate from one biological system to another and accumulate in aquatic organisms and ecosystems.

Besides, old landfills generate flammable gases and volatile organic compounds that can cause explosions and fires that are very difficult to extinguish.

To remedy all these problems and to take advantage of all the materials that can be recycled, recovered or transformed, we promote Landfill Mining. The materials that can be neither recovered nor recycled, we transform into biofuels, syngas, heat and energy.

What can REVALUO Landfill Mining achieve in closed landfills❓

Avoidance of environmental catastrophes and remediation costs.
✔ Reclamation of disposable land.
Material savings and circular economy development.
Production of alternative energy sources.
✔ Recovery of highly valued minerals and metals for industries.
