Moulding Sand Recycling and Reuse in Small Foundries ...
A number of small foundries do not reuse their sand while some reuse it. In this paper we explore how the EffSAfound a German project in collaboration with the Metal Casting Technology Station (MCTS) at the University of Johannesburg reused spent foundry sand in a small foundry. We look at economics of reuse and quality of the reusable sand.

Beneficial Uses of Spent Foundry Sands | US EPA
The metal casting industry generates spent foundry sands. Foundries purchase new, sand to make casting molds, and the sand is reused numerous times within the foundry. This reuse eventually renders the sand unsuitable for use in casting molds, and a portion of the sand is continuously removed and replaced with sand.

What is foundry sand? - Solex
Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.
