From a circular economy perspective, the recovery and reuse of waste plays a fundamental role. Foundries purchase hundreds of millions of siliceous sands every year to create molds and cores that give shape to the casting. These sands, after several uses, become waste that must be properly recovered or disposed of; they are called waste …

As seen in Table 2, two experiments (experiments 5−6) were performed in a smaller size silica sand bed (362.8 g) to examine the effect of volume variation of a silica sand bed on methane recovery. The bed of silica sand was saturated by liquid water, and the height of the sand bed was maintained the same as experiments 3 and 4 (4.94 cm).
