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.
