WASTE INCINERATION

Burning trash doesn’t just turn waste into ash—it can release hydrogen fluoride, a sneaky gas that harms both lungs and the environment. Scientists used to scratch their heads over how exactly this happens in modern incinerators. But a new approach is changing the game. By mixing smart computer tool

Digging into solid waste incineration ash, scientists found that current methods to measure heavy metals and elements like calcium (Ca) and aluminum (Al) weren't cutting it. Why? Because the structure of the ash, especially the silicon dioxide (SiO2), was tough to break down. Using hydrofluoric acid
