Engineered timber CLT

“One of the leading UK CLT suppliers, KLH, describes itself as having a ‘zero waste manufacturing process’, with all off-cuts, shavings and sawdust manufactured into biomass pellets.”

here is currently a groundswell of support for reducing waste in our daily lives. The BBC series Blue Planet II is widely credited as being the impetus for many to reconsider single-use plastics; the Environment Secretary describes being ‘haunted’ by the images of plastic pollution1 and is one of many voices now calling for disposable coffee cups to become a thing of the past. The needless use of resources and wilful creation of landfill should be called out and the media support for these campaigns is welcome, but it is worrying how little attention is drawn to the UK’s biggest waste stream – the construction industry. The most recent statistics published by the Department for Environment, Food and Rural Affairs identify construction, demolition and excavation waste as accounting for 59% of all UK waste in 2014.2 By mass, the sector has seen increases of more than 14% in waste generation on 2012 figures, compared with a 7.8% fall in the commercial and industrial sector.3 These are simplistic figures that don’t account for growth in construction output over the same period, but what is indisputable is the scale of the waste produced – 100 million tonnes of construction waste per year, of which 25% goes to landfill.4 It makes the annual 30,000 tonnes of disposable coffee cups5 a figurative (as well as, sadly, literal) drop in the ocean.

Responsible construction and benefits of CLT Not as headline-grabbing as a latte levy, the British Standards Institute is supporting a shift in attitudes through the BS 8895 series – Designing for material efficiency in building projects. It acts as a valuable prompt to designers with a checklist of considerations to optimise material use from the point of resource extraction to the end of building life. Through this lens, solid timber structures offer solutions in abundance and are leading the way for responsible construction. The introduction of cross-laminated timber (CLT) in the early 1990s has opened up new markets for solid timber and it is perhaps not surprising that such a young branch of the industry should be so environmentally savvy. One of the leading UK CLT suppliers, KLH, describes itself as having a ‘zero waste manufacturing process’, with all off-cuts, shavings and sawdust manufactured into biomass pellets.
