Background

Secure and Sustainable Waste Collection for a Grade-A Office Complex

The Metropolis twin towers (23 and 21 storeys) form a Grade-A office complex in Singapore’s one-north district, earning the BCA Green Mark Platinum award for its advanced sustainable design and operations.

To complement the building’s state-of-the-art features and expansive floor plates, Greenview has endeavoured to implement building-wide shredded paper waste storage and collection system, ensuring that all sensitive documents are destroyed at source and collected for recycling with minimal human intervention.

  • Sensitive documents from Grade-A office tenants required secure, at-source shredding and controlled conveyance.

  • The system had to support the development’s BCA Green Mark Platinum certification by ensuring recyclability with minimal manual handling.

Implementation Approach

To support The Metropolis’s sustainability goals and secure waste handling needs, a shredded paper waste storage and collection system was implemented building-wide.

This innovative solution centers on a dedicated used-paper recycling chute system: high-capacity shredders on each office floor feed confidential waste paper into a vertical conveyance chute, which transports the shredded material to a secure storage unit in the basement.

The system ensures that sensitive documents are destroyed at source and collected for recycling with minimal human intervention.

By integrating confidential shredding into the building’s infrastructure, The Metropolis can handle large volumes of paper waste efficiently while maintaining tenant data security and supporting recycling efforts.

Each floor was equipped with a dedicated paper shredding unit connected to a centralised chute system.

The chute was built with modularity in mind, while the chute chamber incorporated pneumatic gates, dust extraction, and water scrubbers to manage volume and safety.

“This project demonstrates how an innovative waste-collection design can deliver uncompromising document security alongside reliable, sustainable operation in a high-rise environment.”

Expertise in complex PWCS Projects

The Metropolis’s shredded paper waste management system has markedly improved the building’s operational efficiency and green performance. By automating the collection of paper recyclables and destroying confidential waste at its source, the system reduces labor needs and ensures a cleaner, safer workplace for tenants.

This implementation has shown how adaptable such solutions can be: the modular shredded-paper chute concept can be transplanted to other high-rise offices or integrated into future developments to promote secure, smart recycling.
