Techno-economic impact assessment of recycled gypsum
The recycling cost of pre-consumer waste is calculated based on production yield only when processing takes place in internal recycling lines. If this waste is recycled by a third party the respective cost is already built-in in the net unit cost of Such economic instruments along with other economic factors (i.e. “Price of the recycled gypsum” (CF3), “Recycler’s gate fee” (CF6) and “Landfill operation cost” Exploring factors influencing post-consumer gypsum recycling

5 European Gypsum Recyclers Forum 26 May 2021
Based on the discussions held at the 5th European Gypsum Recyclers Forum, Eurogypsum is calling upon EU and national policymakers, as well as gypsum “Other levies and fines”, “Price of the recycled gypsum”). These findings may imply that stakeholders in non-gypsum recycling countries mostly rely on economic aspects to enhance the recovery of gypsum waste.

Gypsum The Canadian Encyclopedia
Gypsum is a mineral consisting of water-containing calcium sulphate (CaSO 4. 2 H 2 O). When calcined (roasted) at temperatures of 120-250°C, gypsum releases 75% of its water. The resulting plaster of Paris, when mixed with water, can be molded, shaped or spread, then dried or set to form hard plaster. Gypsum was used by the builders of theUSA Gypsum’s commitment to continually refining its sorting processes, as well as its capacity to create new gypsum products for different applications, has allowed the company to diversify its reach.

Gypsum Recycling FEECO International Inc.
Gypsum is an exceptional material in that it is endlessly recyclable, meaning it can be continuously recycled to make the same product. Gypsum board recycling typically begins when construction site waste is brought to a recycling center for processing. The recycling center separates the paper from the gypsum and breaks down the gypsum The recycling and reuse of waste plasterboard was given a boost in 2007 with the so-called Ashdown Agreement, an industry initiative led by the Gypsum Products Development Association that setIn the loop: recycling gypsum The Construction Index

Recyclability Process of Standard and Foamed Gypsum
Gypsum is an ancient material, still widely used and suitable for many applications in the constructions, due to its low cost, availability, lightweight, good thermal and sound isolating behaviorDirect mineral carbonation (MC) is used to mitigate carbon dioxide (CO2) emissions. This method has the great advantages of reducing the amount of industrial residues and creating valuable materials by incorporating CO2.

Properties of recycled gypsum from gypsum plasterboards
The increasing consumption of gypsum products compels their producers and consumers to behave in accordance with the precepts of sustainability. Despite the necessity of the integral recycling of gypsum products, only a part of the waste plaster is reused, which leads to the development of products with large quantities of plaster to As can be seen, the material chemical composition does not change, making it a completely recyclable product [].Therefore, many researchers in the last years have been working on the generation of new gypsum materials and products that incorporate recycled gypsum waste as a replacement of the original commercial one [7,8,9].In this regard, Jimenez Use of Polycarbonate Waste as Aggregate in Recycled Gypsum

Exploring factors influencing post-consumer gypsum recycling
First, gypsum contaminates concrete for recycling when treated as mixed waste. Second, the disposal of GW at landfills poses a risk of higher landfill emissions. Overall, potential secondary resources are lost. The main objective of this study is to explore factors influencing gypsum recycling and landfilling in the EU-28.The CDW waste is the most complex to recycle as gypsum is often combined with other building materials; therefore, its recycling efficiency is reduced. The target value of CDW gypsum recycling set up by EU-27 member states is 70% [3]. Up to now, plasterboard CDW can be separated and collected on-site, and when it is Processing of Gypsum Construction and Demolition
