Digging Ourselves Deeper – The Nature of Cities
By transforming that which is challenging and dangerous (and in any case difficult to contain), such as sulfur dioxide and fly ash, into a valuable asset. Much earlier, and clearly inverting our earlier axiom, Paris achieved an elegantly circular metabolism of its food system whereby 'night soil' ( human solid waste) was collected and redistributed as fertilizer to periurban farms.

Journal of Waste Management Hindawi
Biomedical waste ash generated due to the incineration of biomedical waste contains large amounts of heavy metals and polycyclic aromatic hydrocarbons (PAHs), which is disposed of in regular landfills, and results in unfavorable amounts of hazardous materials seeping into the ground and may pollute surface water and groundwater. Therefore, it is essential to remove the toxicity of ash before ...
