Solid Waste and Emergency Response (5306W) Geosynthetic Clay Liners Used in Municipal Solid Waste Landfills GCL Technology Materials A GCL is a relatively thin layer of processed clay (typically bentonite) either bonded to a geomembrane or fixed between two sheets of geotextile. A geomembrane is a polymeric sheet
As the old saying goes, there are about as many ways to recycle clay as there are potters. Many variations are presented below. Find the process that suits your situation the best. Of course, if you have a pugmill, recycling clay can be a lot easier (20). Safety. The most notable hazard with recycling clay is breathing clay dust from dry clay (11).
Clay is very often used in containment systems to regulate water, leachate, and gas fluxes in and out of waste disposal sites. A compacted clay layer (CCL) can be used individually or as a component of a lining system with an overlying synthetic high-density polyethylene (HDPE) membrane (geomembrane) and a drainage layer.
Bentonite Clay. The many uses of Bentonite Clay range from coagulant to filter aid. It is a highly effective chemical, in granular form, for the purification of wastewater and sludge dewatering.
Typical drilling fluid components are not hazardous materials, with the waste material usually considered as excavation spoils, not requiring special disposal procedures. The volume of spoils to be removed from the site may be significantly reduced by means of drilling fluid recirculating systems.

Most low-level radioactive waste is typically sent to land-based disposal immediately following its packaging. Many long-term waste management options have been investigated worldwide which seek to provide publicly acceptable, safe and environmentally sound solutions to the management of intermediate-level waste and high-level radioactive waste.
Apr 10, 2019· Abstract. Summary of a coupled thermo-hydro-mechanical model based on hypoplasticity principles combined with the concept of double structure, aimed to predict bentonite behaviour in the simulations of planned nuclear waste repositories, is presented in this paper.
Bentonite (/ ˈ b ɛ n t ə n ʌ ɪ t /) is an absorbent aluminium phyllosilicate clay consisting mostly of montmorillonite.It was named by Wilbur C. Knight in 1898 after the Cretaceous Benton Shale near Rock River, Wyoming.. The different types of bentonite are each named after the respective dominant element, such as potassium (K), sodium (Na), calcium (Ca), and aluminium (Al).
