Installation of Twin Vertical Chutes in the New Wing

Greenview’s solution involved installing twin vertical chutes – one dedicated to general refuse and one to soiled linen – serving all 9 levels of the new wing.

Each intake point on the ward floors is equipped with an intelligent chute hopper door featuring RFID card access and an electromagnetic lock, plus a digital queue counter display.

Background

Upgrading Waste and Linen Systems in a High-Demand Hospital Wing

Operated by a non-profit organisation, Mount Alvernia Hospital’s new wing is a 380-bed private acute care facility in Singapore. The hospital features 24-hour emergency care, rehabilitation, and specialist clinics.

In 2022, the hospital completed a new nine-story wing to expand its services, requiring the implementation of a modern refuse and linen chute disposal system to manage the high volume of general waste generated daily.

  • The nine-storey expansion required a chute system capable of managing large quantities of general waste and linen daily.

  • The system had to ensure hygiene, safety, and reliability to support critical hospital functions without service disruption.

Implementation Approach

Greenview’s solution involved installing twin vertical chutes – one dedicated to general refuse and one to soiled linen – serving all 9 levels of the new wing.

Each intake point on the ward floors is equipped with an intelligent chute hopper door featuring RFID card access and an electromagnetic lock, plus a digital queue counter display.

Dual vertical chutes (general waste & soiled linen) serve all 9 floors. Smart hopper doors feature RFID access, EM-locks, and a queue display to control sequential use.

At the chute chamber, general waste feeds a storage/collection unit with level sensing, fault buzzer, and fire-control damper; the linen chute includes a breakfall & transition plate for gentle bag transfer to trolleys

Design and implementation of the chute system were carried out in close coordination with the new wing’s construction schedule and hospital facilities management.

Engineers ensured the chute shafts were centrally located on each floor for easy access from the wards, yet sealed off to prevent any odor or noise issues. The chute sections were pre-fabricated and installed floor by floor as the building’s structure rose, ensuring precise alignment of the intake openings on all 9 levels.

“Sequenced, RFID-controlled intake and real-time alerts turned a passive chute into an active, hospital-grade system—cleaner, safer, and easier to run.”

In summary

Highlights

Hygiene and Safety.

  • RFID + EM-locks ensure authorized, one-at-a-time use
  • Interlocks limit cross-drafts and odours

Operational Efficiency.

  • Level sensors and fault alerts optimise pickups and speed up housekeeping workflows

Built for People, Not Just Performance.

  • Breakfall plate reduces impact and prevents bag rupture
  • The transition plate keeps the chute room clean
