Creating a circular economy T
Mike Collins, managing director at Ovia, provides an overview of Technical Memorandum 66 (TM66) – creating a circular economy in the lighting industry.
he UK generated 40.4 million tonnes of commercial and industrial waste in 2020. The EU estimates (2023) that member states produce more than 2.2 billion tonnes of total waste every year. Electronic waste has increased 47% whilst the population has only grown by a 9% in the same time span (2010-2018). This is unsustainable.
The current model of product development is ‘linear’; that is, ‘Raw materials – Design - Production – Distribution – Consumption – Collection – Waste Management/Landfill’, or simplified to ‘Take, Make, Use, Shred/Landfill’. It is this model that has raised the amount of electronic waste to unsustainable levels. The circular economy is a model of production and consumption which places the emphasis on, ‘…sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products for as long as possible’. The circular model provides for greater opportunities to use, reuse, or remake prior to recycling, waste management and/or landfill. This model has the aim of significantly reducing waste.
‘TM66: 2021 Creating a circular economy in the lighting industry’, published by CIBSE, sets out what designing and manufacturing to comply with circular economy principles entails, and includes a checklist, a method of assessing a

product’s circular economy performance, and real-world examples of good practice. TM66 recognises the UK Government’s strategy to eliminate avoidable waste by 2050 and to this end the target is to move the lighting industry towards using fewer resources, make
products more efficient and effective by using, for example, replaceable parts. However, this is a simplistic consideration when considering the whole of TM66.
TM66 provides practical guidance to all elements of the lighting industry, including clients, manufacturers, specifiers, wholesalers, designers and the like in how they might better take account of all the factors which impact upon the Use, Re-use and Re-make of lighting products.
Circular economy and design To ensure that any lighting product follows the ‘circular economy’ model, designers must purposefully design products that follow the user’s needs whilst operating a system whereby resources, manufacturing, distribution, use and re-use of components are given due account in the design of the product.
The circular economy takes account of making use of recycled materials, but it is more accurate to emphasise the need to design waste out of the process at the initial design phase. For example, where an existing luminaire has failed or the space has changed its use, circular economy thinking does not simply throw the luminaire(s) away, rather consideration is given to whether the luminaire can be re-imagined, remanufactured or used in alternative locations. The key question is, ‘how do we retain the maximum value of the luminaire?’ That is, how can a luminaire be kept at the highest level of economic and functional value for as long as
