  1. Case study and how-to guide: conserving water in haemodialysis

    When the Canterbury dialysis unit updated its water purification system with the installation of a new reverse osmosis plant in 1997, it was soon apparent that large volumes of reject water were being ‘lost to drain’. Within two years, and with the help of the hospital’s Estates Department, a simple system capable of recycling 800 litres of this water per hour was installed at a cost of £15,000. The system has now been running for over ten years, saving the Trust £7,500 each year on mains water and sewerage costs. Green Nephrology programme, 2009-2010

  2. Clorox decide to stop using chlorine gas in bleach.

    By ending the use of chlorine gas, Clorox eliminates the risk from the use and transport of chlorine, a decision lauded by Greenpeace.

  4. Surgical hand scrub: lots of water wasted.

    Surgical hand scrub (SHS) is an important antisepsis measure before participating in surgical operation. It reduces the risk of microbial contamination of the surgical wound by skin flora. SHS is usually performed in a scrub sink with taps that have hand operated handles. During the scrub process large volume of water is wasted. The aim of this study was to determine the volume of water used during SHS in comparison to the actual volume necessary. Ahmed A. Ann Afr Med. 2007 Mar;6(1):31-3.

  5. Surgical scrubbing: can we clean up our carbon footprints by washing our hands?

    This study aimed to investigate water use during surgical scrubbing. Two water delivery systems were assessed to see whether technological innovation can promote more ‘environmentally friendly’ scrubbing behaviour. A different tap design resulted in a net saving of 5.7 L of hot water, w600 kJ of energy and 80 g of carbon dioxide emitted per surgical scrub. Surgical scrubbing is a ubiquitous procedure performed daily in healthcare settings. A simple technological solution can reduce water and energy use by modifying hand-washing behaviour and thereby reduce the carbon footprint of surgical scrubbing. J.E.A. Somner.
