0:05 sustainable landfill Reclamation
0:07 technology is to restore as well as
0:10 recirculate active and closed landfills
0:13 which have urgent landfill Reclamation
0:16 needs this technology consists of pre-
0:18 stabilization separation and solid
0:26 production the first step is pre-
0:28 stabilization a process which if
0:30 necessary is used used to remove
0:33 explosive gases including methane as
0:35 well as potentially odorous Gases such
0:38 as ammonia and hydrogen
0:40 sulfide inserting injection and
0:42 extraction well into landfill waste
0:44 layer connecting them to pre-
0:46 stabilization system and then injecting
0:49 mixture of air and aerosol less than 5
0:53 to 25 microm into landfill waste layer through
0:55 through
0:58 distributor after that extracting
1:00 explosive gas and odor gas generated
1:02 from this process to treat with
1:04 biofilter and then Excavating and
1:07 transporting stabilized landfill waste
1:16 area the second step is the separation
1:18 process which sorts the landfill waste
1:21 into soil combustible materials
1:24 incombustible materials and metal the
1:25 landfill waste is removed from the
1:27 landfill and transported to the
1:30 separation units where a back ho places
1:32 es it into the automatic feed Hopper if
1:34 a potential odor is detected during the
1:36 separation a deodorant is sprayed into
1:39 the waste material in the first step a
1:41 trml screen is used to remove and
1:43 separate the soils present in the
1:46 landfill waste which are less than 35 mm
1:49 in diameter the TRL screen is equipped
1:52 with customized blades on the inside and
1:53 brushes on the outside to prevent
1:57 clogging of the screen by the soils and
2:00 wastes the recovered soils of less than
2:03 35 mm diameter which contain non-soil
2:05 materials such as fragments of organic
2:08 material vinyl or plastic are not
2:10 allowed to be used for cover soils or
2:13 construction filling the TRL screen is
2:15 combined with a rotating rake allowing
2:17 highly accurate and efficient sorting
2:19 and separation of those smaller
2:22 fragments allowing the separated soils
2:24 to be
2:27 recycled after passing through the TRL
2:29 screen rotating rake the separated so
2:31 oil is transferred by a conveyor to a
2:34 storage pile typically located outside the
2:42 enclosure after removal of the under 35
2:45 mm clean soils by the TRL screen
2:47 rotating rake the remaining waste is
2:50 separated into combustibles and Inc
2:52 combustibles in a series of five
2:54 separation stages which comprises the
3:04 Metals included in the combustible
3:06 fraction are recovered by a magnet and
3:08 are transferred by a conveyor to a
3:10 storage pile which is typically located
3:30 enclosure
3:32 the incombustible fraction is
3:34 transferred by a conveyor to a storage
3:37 pile which is typically located outside the
3:41 enclosure the soil and the Inc
3:43 combustibles recovered from the sorting
3:46 system can be recycled and used as fill
3:49 material cover soil construction base or other
4:00 uses
4:02 the third phase of the process is the
4:05 production of refu derived fuel rdf from
4:08 the remaining combustible materials by a
4:10 series of shredding purifying grinding
4:13 and drying steps the combustibles enter
4:15 a shredder and are reduced in size to
4:18 less than 150 mm in size any Inc
4:20 combustibles remaining in the fraction
4:22 are removed by another separator to
4:24 enhance the combustibles quality and
4:27 heat value as rdf any metal remaining in
4:29 the combustibles fraction is removed by
4:32 magnet and ground into particles less
4:44 grinder incombustible foreign matters in
4:46 the ground combustible stream are
4:48 removed by a vibrating screen light
4:51 combustible material is removed by a
4:57 device heavy combustible components are
5:07 separator the combustible materials
5:10 recovered by the tornado vacuum and the
5:12 Precision separator then enter a second
5:14 grinder where they are ground to less
5:16 than 50 mm in
5:19 diameter the ground combustibles are
5:21 dried as necessary to meet the standards
5:24 of rdf by passing through a first stage
5:27 and second stage dryer producing fluff type
5:28 type rdf
5:31 rdf
5:34 finally the fluff type rdf enters a
5:36 compactor and baor producing a
5:38 compressed Cube to facilitate storage
