1. Brief description
The present invention relates to a novel system for
the safe temporary storage and processing of
municipal solid waste above and below surfaces
and using special fabric bags and special design.
For the manufacture of bags special technical
fabric is used. Over the special technical fabric,
waste is deposited and special fabric wrapped
around them and then stitched with special sewing
or fusible machine, creating the bag. In the bag
there are 3 valves. There is a valve at the top for
extraction of biogas and a valve for introducing
water or any other fluid mixture. At the lowest
point , there is a drain valve leachate. The biogas
and leachate led to temporary storage tanks.
The system can be developed into an integrated
system for energy recovery of waste stored with
minimal cost compared with other systems. The
system is used for any amount and type of waste.
2. Methodology
The storage process begins with the deposition of
of specialized technical fabric at the territory, at
which the bags are constructed in the selected
store. The dimensions of the specially produced
technical fabric may vary, depending on the
desired size of the bag. The special technical
fabric, has the specifications listed in the following

The wastes enter the storage place from the garbage
tracks. These wastes can be Municipal Solid or liquid
waste, mill waste, dairy waste, waste Farms, etc. The
waste can then be compressed to reduce their volume.
Then the waste is put onto the open special technical
fabric, covering about half of fabric. The remaining
fabric is wrapped around the waste, thus creating the
storage bag, closed on the spot or by special machine
double seam or a special heat-sealing machine ( Figure 1
) . In the case of wastewater, the bag is prefabricated
and wastes are placed inside the means of a special
valve. The specific technical fabrics are made with new
technology materials that withstand very high pressures
without tearing or cracking, (thus avoiding the
unpleasant odors from waste throughout the period of
storage).
Figure 1: Method of waste disposal and creation of
storage bags
At the specific technical fabric bag storage, there
are at appropriate points leachate drainage valves,
exhaust valves biogas and water inlet valves. The
following diagrams show the structural layout of
the bag.
Figure 2: Construction of the bag
Figure 3: Layout of multiple bag
The use of specialized technical fabric, which is the
construction material of the bag (1), ensures that
the bags are tightly sealed. This ensures the
complete absence of unpleasant odor in the
surroundings. Inside the bag fermentations are
made, which are expected as a consequence,
digestion of waste placed in the bag to be carried
(7). Result of this process is the production of
biogas. The bag has at the center of the upper
side, special biogas outlet valve (3) through which
the produced biogas exits the bag and can be
stored temporarily in a biogas reservoir (6). The
stored biogas can then either be burned in situ,
through special torch, or transported, to be used
in various applications. Through fermentation
carried inside the bag are liquid waste (leach ate)
is also produced. The bag has a trough , special
valve basin drainage. Effluents have the potential
to lead to a special tank leach ate (5), which
remain provisional until their transfer in biological
purification. Alternatively, if possible, the leach ate
can be transported directly to the sewage
network. The leach ate drainage tube may be
above ground (as in diagram), or underground.
Given the unknown composition of the potential
for waste storage, there is the possibility of
leachate to not be suitable for direct use in
biological purification. The construction of the bag
there is a special water inlet valve or any other
suitable liquid mixture (4). This valve is located on
top of the bag. This valve allows, where necessary,
water is introduced or any other suitable liquid
mixture so as to reduce the toxicity of leach ate
generated. This valve can simultaneously be any
other possible use for import of substances inside
the bag.

3. System uses
The above system can be used for temporary
storage of waste until transport to landfills,
incineration plant, pyrolysis or any other form of
waste treatment. Alternatively, the same space
can be embedded integrated energy recovery
system of total waste. It can also be used to
restore XADA (site for the uncontrolled landfill of
waste), safe caching of existing waste.
The system can be used to temporarily store the
following types of waste :
1. Mixed Municipal Solid or Liquid Wastes
2. Pressers waste
3. Livestock waste
4. Cheese waste
