Gypsum Waste Minimisation Most drywall projects inevitably generate plasterboard waste but much of this can be avoided through good design and site practice. On many building sites there’s a 10% waste factor, and in some cases it’s up to 25%. Few offcuts are suitable for use elsewhere, so most go to waste. There are many good reasons for this waste: doorways, windows, irregular room shapes and non-standard ceiling heights are typical examples. We’ve looked carefully at various sources of plasterboard waste to explore how it can be reduced or avoided and we can advise on detailing to reduce waste. For example, a floor-to-soffit height of 2,400mm means that most plasterboard products will fit precisely – with no additional effort and no waste. If a non-standard height is unavoidable we may be able to help with cut-to-length plasterboard solutions. We know that some gypsum waste results from bad handling of boards on site or accidentally exposing plasterboard to wet weather. Material waste like this is expensive in time and effort. Through our Project Specification Managers and our Training Centre, we provide advice and training on the correct techniques for handling and working with materials on site – helping you to avoid problems and ensure the best possible productivity.

Collection systems to suit every site
	Bulk bags
	1m³ bulk waste bags are used to collect plasterboard waste from house building sites. They can be placed anywhere within range of a lorry-mounted crane for easy removal.
	Wheelie bins (660 litre)
	660 litre wheelie bins are used in large or high rise buildings and can be moved close to the installers for convenience. They are taken to a central point for loading into a mobile compaction unit.
	Skips (6–14 yards)
	5–11m³ skips are used on medium to large sites where centralised waste collection is a convenient solution.
	Ro-Ro skips (35–40 yards)
	27–31m³ roll-on, roll-off containers are used on major sites that generate large waste streams and where storage space is not at a premium.
