Gypsum recycling systems Redox Waste Recycling B.V. The gypsum recycling system is designed to recycle gypsum plates and bricks at a high
Redox-induced P release was less from gypsum-amended than unamended soils. Gypsum amendment reduced both pore water and floodwater P concentrations. Adding gypsum reduced floodwater P concentration to a maximum of 57%. The effectiveness of gypsum in reducing P release from flooded soils is soil dependent. Published December 27, 2018
Where we are with recycling drywall today New West Gypsum Recycling British Columbia, Canada. New West Gypsum Recycling began recycling wallboard waste in Canada in 1985. The recycled material is a blend of pre-and post-consumer, wet and dry gypsum waste that is a source of raw material for use in the manufacture of new drywall products.

Ana Jimnez-RiveroJusto Garca-Navarro, in Advances in Construction and Demolition Waste Recycling, 2020. Abstract. Gypsum products are well suited for a circular economy, because the raw material calcium sulfate dihydrate can repeatedly change its properties through a reversible hydration reaction. However, quality postconsumer recycled gypsum can only be obtained

The countries in which a gypsum recycling market does not yet exist, gypsum is segregated to avoid the contamination of waste concrete (Barbudo et al., 2012 Silva et al., 2014 Tovar-Rodrguez et al., 2013). As a result, the opportunity to produce recycled gypsum is created, but not the infrastructure to produce the recycled gypsum.

The technology relates to an innovative redox targeting-based process for the recycling of spent lithium iron phosphate (LiFePO 4) batteries. With 0.20M of ferrocyanide Fe (CN) 6 3- solution as a selective and regenerative redox mediator, LiFePO 4 is readily broken down into FePO 4 and Li via the redox-targeting reaction.

Recycling Approximately 700,000 tons of gypsum scrap that was generated by wallboard manufacturing was recycled onsite. The recycling of wallboard from new construction and demolition sources also took place, although those amounts are unknown. Recycled gypsum was used primarily for agricultural purposes and feedstock for the
duct (gypsum), while the remainder generate approxi-mately 20 million tons per annum of disposable ue gas desulfurization (FGD) byproduct, which are trans-ported and disposed of in landlls 3. The use of regenerable sorbent technologies has the potential to reduce or eliminate this solid waste production, trans-portation and disposal.
