Contamination of surrounding environment by leachate and air borne dust from pond.
Red mud spill by dam failure (breach).
Additional risk due to disposal of „composted“ hazardous wastes.

STATE OF ART FOR LANDFILL DESIGN
Risk-Minimisation by MULTI-BARRIER ConceptHydrogeological Barrier:→ Proper site selection with safety criteria(i.e. low risk area with impermeable underground).Technical Barrier:→ Technical measures and installations(i.e. base liner system, leachate collection and treatment, capping system, etc.).Internal Barrier:→ Landfilling of non-reactive waste after pretreatment and inertization.Monitoring

ALMÁSFÜZITÖ: High Risk Site
due to non-existing Barrier SystemsPhotodocumentation:
Observed exit of Red Mud at Embankment Dam Slope and percolating alkaline leachate at Dam Foot.

RED MUD POND VII ALMÁSFÜZITÖ
Existing Site-specific Risks:Location on Bank of River in flood areaLocation within earthquake prone regionLocation with permeable underground of River Sediments (sands & gravel)
No Base-Liner SystemNo Leachate Collection SystemNo Capping System (only partially covered)Questionable Dam Stability
Liste of Waste also contains many inorganic substances.

STATE OF ART FOR HAZARDOUS WASTES
→ CHEMICAL-PHYSICAL (CP)-TREATMENT
Aerobic biological treatment („compostation“) of Hazardous Waste is not at all recognized as sustainable Methode or not feasible for inorganic wastes (e.g. Aluminium dross).„Composting“ of Hazardous Wastes in ALMÁSFÜZITÖ is based on DILUTION with SOIL-like materials and has to be considered as high risk methode.
Name, 21.04.23, Folie 10
PROOF:IR-camera pictures taken from compost prisms are showing no biological activity.Analyzed samples are having totally different composition compared to compost (e.g. TOC: 2-7.5 % only, but high values for the parameter AOX and evaporation residue).
Name, 21.04.23, Folie 11
CONCLUSION Red Mud Pond VII at ALMÁSFÜZITÖ already is
a HIGH RISK SITE because of unfortunate local conditions and the lack of Technical Barrier Systems.
The aerobic biological treatment (or: compostation) of hazardous wastes is not at all a recognized methode and has to be considered as risky and non-sustainable.„DILUTION OF POLLUTION IS NO SOLUTION“
Covering of the ALMÁSFÜZITÖ Red Mud Pond VII with „composted Hazardous Wastes“ definitely will further increase the high risk potential of the location and therefore endanger the surrounding environment.
