Option 2: Container with compaction on road
In this option, the waste is compacted before
loading into containers. The objective is to reduce
the size of the transportation fleet, which in turn
means reduction of the number of trips and overall
investment. The option works with using sticks to
the present way of waste delivery to the landfill
using the road. The preload compaction system
can compress the waste in range of 400-500 kg
per cubic meter. If compared to the 300 kg/m
3
average current waste density increase the
capacity of containers to about 30-40%.
Option 2a: 50 m³ containers on semi-trailers
The containers of 50 m³ volume are put on
semi-trailers, the loading is via the compaction unit
(Chapter 5), the unloading via push-out blade.
Compaction of waste is performed by installation
of compactors at the existing transfer stations.
Option 2b: Two 30 m³ flexible containers
This option is increasing the transported
amount of waste by using two 30 m³ containers:
one each on the chassis and the trailer. Loading
and un-loading will be done with the help of a
hook-lift. The hook lift will also be used to lift the
container from the trailer and to empty it too.
Option 2c: 65m³ containers on semi-trailers
This option is the continuation of option 1 after
addition of compaction facilities at the existing
transfer stations. Also, it utilizes 65 m³ fully closed
containers fixed on semi-trailers which are filled
with compacted waste at the transfer stations and
pulled to the landfill by tractors. The process of
unloading waste at the landfill is made through
installation of push-out blades at each container.
At the new transfer station (with railway
connection) compactors will be installed. The
delivered waste is tipped into the compaction
hopper and pressed into enclosed 30-ft container.
The delivery from nearer districts is directly done
by collection vehicles, from far-away districts the
existing transport vehicles transport from the
existing transfer station to the new one. In this
mode a part of the existing transfer stations can
be closed to save space and personnel. The full
container is removed from the compactor and an
empty one is linked by an automatic container
change system.
