SOLUTIONS

Also known as the “Pneumatic Waste Conveying System”, AWCS collects and transports trash, recyclables and organic waste through a fully sealed underground system at a high speed from the waste chutes and outdoor load stations directly to a central collection centre located away from inhabitants.

AND SINCE EACH DEVELOPMENT IS UNIQUE, OUR SYSTEM CAN BE CUSTOMISED TO MEET ANY REQUIREMENTS OR SPECIFICATIONS.

The illustration on the left shows the basic concept of how a standard STREAM’s AWCS works:
  • Chutes and hopper doors are used to feed waste into the system.
  • Storage sections hold waste between transport cycles.
  • Primary air inlet that creates a highspeed air path in the pipe network.
  • Discharge valves that periodically open to allow movement of the waste into the active air path.
  • Transport pipes that form the waste path between the storage sections and the Central Waste Handling Facility (CWHF) / bin room.
  • Outdoor load stations that may also feed smaller quantities of waste material into the system.

FULL VACUUM SYSTEM (FVS)

Simple yet effective, this system is able to handle heavy amounts of waste from commercial developments.

  • Trained users dispose waste into key-operated load stations.
  • Exhaust fans start once they system is turned on.
  • Vacuum suction is activated at loading point for quick, easy disposal.
  • Waste is transported via chutes and pipes to a Central Waste Handling Facility (CWHF).

GRAVITY VACUUM SYSTEM

An efficient system, suited for residential and hotel based developments.
  • Waste is discarded through volumetric controlled hoppers into chutes.
  • Waste is dropped and stored temporarily until the next transport cycle.
  • Once waste reaches a certain level or due to a preset timer, the exhaust fan is activated.
  • The discharge valve is opened to unload waste into the pipe network, transporting waste directly to sealed containers at the CWHF.
  • Containers are collected and emptied periodically by flatbed armroll trucks.

REGULAR PUBLIC OUTDOOR LOAD STATION (LITTER BIN SYSTEM)

This system is a public litter bin with a difference, as each bin is connected to an underground waste transport pipe. When the capacity of a particular bin is reached, a sensor activates the discharge valve where the waste is sucked through into the underground pipes, which leads to a CWHF.

Suitable for public parks, barbeque areas, high streets, pedestrian walkways, tourist hot spots, boulevards, beach waterfronts, night markets, stadiums, and shopping areas.

ULTRA LARGE OUTDOOR WASTE LOADING SYSTEM

When handling tonnes of waste per day, efficiently is critical. This system ensures fuss-free operations and features an integrated feeder unit system, which is essentially a load station with an opening lid. Workers can haul various types of bins to the load station and tip the garbage into the system. From the load station, the garbage is fed into underground vacuum pipes for transport to a CWHF.


Suitable for public gatherings, sporting events, religious pilgrimage sites, and street & music festivals.

FOOD WASTE SYSTEM

STREAM has developed a patented system that manages food waste better than any other known AWCS in the world. The system is proven to be energy-efficient, compact, highly scalable and cost efficient. It effectively captures food waste from its source in kitchens, then collects them in containers or delivers directly to food waste treatment plants. High volume food waste generating industries will benefit from this economically sensible and environmentally conscious system.

 

Suitable for hotels, banquet kitchens, airports, catering centres, restaurants, food courts, wet markets, and food processing plants.
