Polyurethane (PU) started as a solution to a 1930s shortage, but today it's a key material in industries from insulation to cushioning. Invented in 1937 by Otto Bayer and his team in Germany, PU was originally designed as a cheap, versatile alternative to rubber. It quickly became popular in coatings and adhesives for its strong bonding and protective properties. PU is made by reacting polyols and isocyanates, which generates heat and, in the presence of expansion agents such as water or gases, creates bubbles that cause the material to expand, resulting in a foam with adjustable density and structure. Its flexibility allowed PU to revolutionize industries with products like insulation and padding. However, its durability and non-biodegradability have raised environmental concerns. To address this, companies like Purman are leading the charge in recycling PU waste, helping to reduce its environmental impact while promoting more sustainable alternatives.

The AlUla Arts Festival, running from January 16th to February 22nd, 2025, features a significant exhibition of works by renowned Light and Space artist James Turrell. Presented by Wadi AlFann, the exhibition, curated by Michael Govan of LACMA, offers a unique preview of Turrell's upcoming monumental commission for Wadi AlFann, a sprawling contemporary art destination in the AlUla region of north-west Saudi Arabia. The exhibition, located in AlJadidah Arts District within AlUla's historic old town, provides context for Turrell's ambitious project, which will involve the creation of a series of chambers within the canyon floor, designed to create a sensory experience of light, color, and perception.
