An investigation of waste foundry sand in asphalt concrete mixtures

Waste Management & Research: The Journal for a Sustainable Circular Economy, 2006
A laboratory study regarding the reuse of waste foundry sand in asphalt concrete production by replacing a certain portion of aggregate with WFS was undertaken. The results showed that replacement of 10% aggregates with waste foundry sand was found to be the most suitable for asphalt concrete mixtures. Furthermore, the chemical and physical properties

Waste foundry sand regeneration

Proceedings of XVI International Mineral Processing and Recycling Conference - zbornik radova
The casting industry uses large quantities of quartz sand, which is a cheap and accessible raw material that must be prepared for use in foundries. After the casting process, foundries generate huge amounts of waste foundry sand (WFS) as industrial waste.

Evaluation of Formaldehyde in Foundry Waste Sands Using Liquid Chromatography [PDF]

Analytical Letters, 2009
Abstract The industrial manufacturing of metallic objects results in a high level of foundry waste sands that may contain toxic compounds such as formaldehyde. The formaldehyde content of foundry waste sands was evaluated by liquid chromatography. Samples were collected during various steps of the industrial processes.

Social, Technological, Economic, and Policy Factors in the Circular Economy Transition in Brazil

Sustainable Development, EarlyView.
ABSTRACT A well‐functioning circular economy (CE) integrates resilience across economic, environmental, and social dimensions. This study identifies key drivers and barriers to Brazil's CE transition through 20 semi‐structured interviews with stakeholders. Major sociocultural barriers include inadequate education and limited CE awareness, while growing
