Is plasterboard toxic?

The key ingredient in plasterboard is gypsum, a fine sulphate mineral mixed with water and pressed between two lining sheets before being dried out to create a solid board. While it’s usually a harmless material, when placed with biodegradable waste it is known to create a toxic gas – hydrogen sulphide (H2S).

Is gypsum toxic in water?

Gypsum Poisoning. Anaerobic bacteria are common bacterium that can exist in gypsum that was NOT properly processed. When the gypsum becomes damp, the bacteria works with the oxygen in the water and converts the calcium sulphate into calcium sulphide, which produces a poisonous gas called hydrogen sulphide.

What is the problem with gypsum?
