Background

Upgrading Waste Systems in a Critical Healthcare Environment

Located in Kent Ridge, Singapore, the National University Health System (NUHS) is a leading academic health cluster comprising the NUHS Tower Block and NUH Kent Ridge Wing.

The facility’s multi-storey infrastructure includes a main building and a support services building, housing critical hospital operations and support systems. requiring system upgrades to enhance the reliability and safety of the hospital’s waste management infrastructure.

  • Waste management upgrades had to adapt to the hospital’s tall, multi-building layout with diverse operational demands.

  • Enhancements were required to ensure uninterrupted operation in a facility where system failures could disrupt essential healthcare services.

Implementation Approach

In the NUHS Tower Block, Greenwave supplied and installed a proprietary refuse chute breakfall device and chute connector. These components were designed to safeguard the compactor at the 14th storey from high-impact refuse discharge.

Greenview also replaced the existing mini-compactor with a new system optimised for safe refuse transition into 660L wheel bins in NUH Kent Ridge Wing, along with a complete refurbishment of the refuse and linen chute system.

Comprehensive servicing and maintenance support are provided to ensure operational uptime of chute and compactor systems in this critical healthcare setting.

The project was carried out in active hospital conditions, requiring precise coordination to avoid disruption to critical operations. GWS scheduled phased work within hospital operational hours and employed hospital-grade safety controls.

Maintenance servicing was integrated post-installation to support continuous system uptime and operational readiness

“In high-dependency environments like hospitals, waste infrastructure must not fail. Our chute and compactor solutions were engineered for durability, safety, and continuous operation.”

In summary

Highlights

Refuse Impact Mitigation at NUHS Tower Block

  • Custom breakfall device absorbs high-level refuse impact from 14-storey chutes.
  • Tailored to the vertical waste flow of high-rise medical facilities
  • Reduces wear on the compactor while suppressing noise for patient comfort

Refurbishment of Linen & Refuse Chutes

  • Existing infrastructure refurbished for dual waste and linen use.
  • Minimised disruption to 24/7 hospital operations
  • Upgrades included noise reduction and ease of servicing.

Waste System Upgrade at NUH Kent Ridge Wing

  • Aging mini-compactor replaced with efficient 660L bin system.
  • Enhances waste transfer, minimises manual handling and downtime.
  • Designed to meet the daily operational demands of clinical settings
