​Derived as a by-product of the Bayer Process, bauxite residue, also known as red mud, poses challenges and opportunities in the aluminum production cycle. Comprising iron oxides, titanium dioxide, silicon oxide, and undissolved alumina, the residue embodies the unextracted elements from the ore.

The initial stages involve washing to extract valuable caustic soda and dissolved alumina. However, this leaves behind a highly alkaline residue, with pH levels often exceeding 13. Alongside its key components, trace elements like arsenic, chromium, and naturally occurring radioactive materials persist post-extraction.

Therefore, the quest for remediation and rehabilitation is crucial. Techniques such as bio-remediation aim to transform the residue into structured soil, offering promise in countries like Ireland, Australia, India, and Jamaica. The method targets pH reduction through various treatments, leaching of salts, and enhancing organic matter content for sustainable use.

In parallel, researchers have explored ways to utilize bauxite residue, with trials focusing on construction, agriculture, and industrial applications. The challenge lies in aligning the annual tonnage of residue – approximately 150 million tons – with feasible commercial uses.

Looking ahead, the industry envisions closing the circularity loop by harnessing the potential of bauxite residue. With an estimated global inventory of 10 billion tons by 2050, the aim is to integrate residue into industrial processes as a sustainable alternative raw material. The journey toward sustainable bauxite residue management embodies a quest for balance between navigating challenges and unlocking its latent potential for a more environmentally conscious industrial landscape.

​The Cardinal Shehan Center held its annual Women’s Golf Classic on October 23, 2023, at the Race Brook Country Club in Orange, Connecticut. The Shehan Women’s Golf Classic embodies a philanthropic spirit, benefitting the center’s after-school and Saturday programs.

With various sponsorship levels available, from major sponsors to hole sponsors, the tournament aims to raise vital funds to support the center's initiatives for young people in Fairfield County. Therefore, the tournament focuses on swinging into action for a cause. 

The day’s schedule included a blend of golf, learning, and celebration, kicking off early in the morning with a light breakfast, setting the tone for a day filled with camaraderie and competition. The tee-off at 11:00 marked the start of an 18-hole scramble format.

For those participating in the Lunch-n-Learn event, the day offered a unique opportunity for skill enhancement. A golf clinic followed by an hour on the course ensured enjoyment and learning. As the sun set, the ambiance shifted to a relaxed yet vibrant atmosphere with cocktails, dinner, auctions, and the prestigious Trish Lind Migliore Commitment Award presentation.
