The brief

With a history of installing high-profile pneumatic waste collection systems within the healthcare sector dating back to 1961, Envac was a natural fit for Hainan Cancer Hospital – a cutting edge hospital in Haikou City, China, designed to promote optimism, empowerment and rehabilitation, as well as foster a sense of community for staff, clients and visitors.

To support the hospital’s design and holistic values, Hainan Cancer Hospital required a waste collection system that would save money whilst dramatically increasing the hospital’s productivity and hygiene levels.

The project

Envac developed and installed a system capable of handling the laundry of 1,200 hospital beds and the general waste of over 11,000 staff and patients across the hospital’s 230,000m2 build area.

A general waste system was also connected to the hospital’s staff quarter during the latter stages of the site’s construction.

The system now transports almost 13 tonnes of waste from the site’s 628 waste inlets each day throughout a pipe network spanning almost two miles (2.7km).

The result

Since the project was fully built out in 2015, Hainan Cancer Hospital’s Envac system has:

  • Dramatically improved the hospital environment – for patients, visitors and staff
  • Reduced the risk of spreading infections. By minimising the risk of cross contamination from waste-related pathogens, both airborne and physically spread, Hainan Cancer Hospital has significantly improved infection control and cleanliness levels
  • Minimised the operational cost of waste collection compared with conventional, manual methods, as staff required for transporting waste and soiled linen around the hospitals have decreased
  • Improved the working environment and hygiene levelstransportation staff no longer have to push and pull heavy trolleys around the hospital corridors, which can pose a risk to staff, patients and visitors
  • Installed a system that is fully operational 24 hours a day, 365 days a year and reflects the hospital’s forward-thinking approach to healthcare technology
  • Added value to the hospital by simplifying the logistics associated with hospital waste collection

“Given the size of the hospital traditional modes of waste collection and transportation are no longer viable. With a strong hospital portfolio in China, Envac has not only proved that its technology is tried and tested but also highly successful in densely populated areas. It’s also much more hygienic than traditional waste collection which, as a hospital, is one of our main priorities. Envac will make waste collection easier and quicker whilst freeing up valuable corridor space as manual waste collection movements will be reduced by 90 per cent.”

Mr Wang Tie Lin, Director of the hospital at Hainan Cancer Hospital
