According to a study, replacing natural gypsum with RGD not only reduced the environmental impacts of extracting gypsum but also boosted the compressive strength of composites made of the cement. This outcome is completely aligned with the proposed close recycling loop of RGD in earlier studies . 5.6 Plaster

The ambitious closed-loop project, hosted at the only gypsum wallboard manufacturing site in the state of New York, comes as Saint-Gobain continues to roll out its new global Grow and...

The "Availability of natural/FGD gypsum" (CF4) can be considered an environmental factor that affect the uptake of RG. 79% of respondents identified this factor as important or extremely important for closed-loop gypsum recycling. Until the 1980s, most of the gypsum feedstock was natural.

Gypsum-to-gypsum recycling – closed-loop recycling means teamwork PORR and Saubermacher are active as strong players on the deconstruction and disposal market, which ensures the delivery of the gypsum waste. Among other things, recycling specialist Saubermacher offers new digital logistics solutions for transporting gypsum …

13 million tons of gypsum wallboard debris are generated in the US every year, 85% of which is landfilled. In landfills, decomposing gypsum can produce dangerous gases such as hydrogen sulfide. However, gypsum …

The gypsum CDW recycling efficiency is still being investigated and evaluated to reach the highest efficiency of a closed life-cycle loop of gypsum binder. The properties of gypsum binders coming from four types of CDW have been investi-gated in this research. The recycling process and the properties of the secondary gypsum …

In a closed loop, goods are recycled over and over again and remade into the same (or similar) products every time, without any waste going to a landfill. Closed loop recycling works for materials ...
