The traditional linear ‘make, use, dispose’ model of consumption is not only extremely wasteful but contributes to greenhouse gas emissions. However, within the lighting industry, the concept of circularity has recently gained increased attention with the development of CIBSE Technical Memorandum 66 (TM66), published by the Society of Light and Lighting (SLL) in 2021.
TM66 sets out by explaining the Circular Economy, defining its drivers and barriers, and then TM66’s Circular Economy Assessment Methods (CEAM) provides a unique assessment that quantifies how circular a lighting product is. Although still in a beta stage, through CEAM, a complex subject can be turned into a comprehensible star rating, giving manufacturers and specifiers targeted, useable, independent metrics to compare products and strive for improvement.
We recently sat down with Bob Bohannon, Head of Policy and Academy at The Lighting Industry Association (The LIA), to discuss the significance of TM66 and what this means for the industry.
