Since the gypsum makes up approximately 90% of the weight of a piece of drywall, if the gypsum can be recovered from the drywall, the majority of the material can be recycled. Scrap gypsum drywall is currently being recycled in several locations in North America. Examples include: The manufacture of new drywall.
How is gypsum recycled?
Once the paper facer is removed from gypsum board, the core, which is essentially gypsum, can be recycled as an additive to concrete, plaster, and stucco. The core material can be reused as a soil amendment, as a water treatment to settle suspended clay particles and added to animal bedding to absorb moisture.
How do they recycle plasterboard?
Gypsum recycling process Gypsum waste can be turned into recycled gypsum by processing the gypsum waste in such a way that the contaminants are removed and the paper facing of the plasterboard is separated from the gypsum core through mechanical processes including grinding and sieving in specialised equipment.

Why should we recycle drywall?
Drywall can be recycled into new products, thereby: Creating business opportunities. Saving money for builders, contractors, and home renovators. Helping local governments meet their goal of reducing disposal by 50 percent.

What is recycled plasterboard used for?
Once recycled plasterboard can be used in a variety of ways including: Production of new plasterboard. A key ingredient in the production of cement. Alternative material for making blocks or bricks.
Why is plasterboard not allowed in skips?
Due to plasterboards gypsum content, it contains lots of sulphates, that when mixed with general waste and rubbish creates a chemical compound known as H2S, hydrogen sulphide. When this is allowed to happen and it gets wet, the plasterboard goes through the process of creating H2S which is called putrefaction.
Does drywall decompose?
Does drywall decompose? Under oxygen-depleted conditions, such as in a landfill or several feet underground in a covered hole, the gypsum (calcium sulfate) in drywall can decompose to release the noxious gas hydrogen sulfide. Drywall is composed of paper facings and gypsum.
Is drywall biodegradable?
Sheetrock, also called drywall, is in the walls of almost any building constructed over the last few decades. It is made of gypsum, a soft rock, with thick paper on each side. Gypsum is natural, and will absorb water and break apart. The paper is biodegradable.
