Convenient waste disposal
The gravity chute.
Gravity chutes carry waste from upper floors to a central collection point that is easy, safe and hygienic.
3+Gravity chutes are mandatory for all buildings with three (03) storeys and higher.
Types of chute
- Garbage chute
- Linen chute
- Paper chute
- Podium chute

Elite design system
Smarter, cleaner chutes.
Designed and built with a focus on sustainability, managing waste at source and moving it from any floor to the collection room.
- 01
Energy efficiency
Less wiring and lower voltage requirements.
- 02
Health & hygiene
Automatic cleaning with smart controls.
- 03
Water efficiency
Flow meter and fluid sensor regulate water and sanitiser use.
- 04
Indoor air quality
In-chute air quality sensor signals the system to respond.
- 05
Local fabrication
Manufactured locally on modern machines that combine several production stages.
Engineering
Sections & components.
More than a vertical tube: every section, collar and joint is engineered for smooth, snag-free flow.
The pipes
Duct pipes are the backbone of each chute, connecting floor to floor like a clean engineered spine.
- Intake & extension pipes
- Telescopic joint & grooved piping
- All pipes fully welded
The pipe support
The hidden strength that keeps every chute tall, stable and safe.
- Support frame
- Steel ring clamps
- Wall angles
- Anchor bolts
Pipe applications
Painted: DEDPAN DC 1050A low-VOC sound damping compound. Eliminates sound and leakage, prevents oxidization, fire-resistant.
Insulated: added thermal insulation for extra acoustic protection, subject to site conditions.
The cleaning system
Housed in the mechanical access unit.
Sanitizing S-Unit: solenoid valve, gate valve and sanitizing tank release pressurized water with disinfectant.
Brush unit: moves up and down, scraping the inner wall of the chute.
Engineering
From roof to collection room.
- The chute’s airway
Ventilation unit
Exhausts undesirable odours into the atmosphere. Fan housing with ventilation fan, ventilation pipe and reducer, fabricated to extend 1,200 mm (4 ft) above roof level.
- Where disposal begins
Intake hopper door
2-hour fire-rated, hand or foot-pedal operated, 24 VDC. Red “busy” and green “available” indicators, electric strike lock, gas spring, gasket and sprinkler adaptor.
- The final waste passage
Discharge pipe
A velocity reducer at the impact zone slows falling refuse for safety and avoids clutter in the collection room. 2.0 mm reinforcement plate; one offset at the base, subject to site conditions.
- The command hub
Control panels
ODO manages doors, safety and indicators. Brush adds cleaning-cycle control. AWCS links the chute to automated waste collection.
Where every disposal ends
Waste handling equipment.
The building’s final waste containment, keeping the collection room clean, organised and ready for recycling or disposal. S.S., G.I. and HDPE bins, plus compactors.

- 80 L to 24 L Household small HDPE (80 · 65 · 60 · 46 · 45 · 40 · 24 L)
Space savers
Bin compactors.
Portable compactors that reduce garbage size to 20–25% of the original volume. Less cumbersome and space-saving, ideal where the collection room is tight.
