| Description:
The Izoling technology uses waste fibrous materials for
manufacturing of a mass used for covering of the daily landfill
waste supply.
The Izoling mass can be manufactured using:
-
waste paper not suitable for reuse in paper industry because it is
wet and polluted with organic leftovers: juice or milk packaging,
cardboard boxes, etc.
- various textile wastes of natural and
synthetic materials, including dirty ones
After shredding of
fibrous materials and subsequent mixing them with water (if need be
also with disinfectants, smell absorbers, sand) a felt-like mass is
obtained. After spreading over a landfill the mass stiffens in a
short time and constitutes a very good material separating the
landfill deposits from the surrounding environment.
The Izoling
mass can also be used in land reclamation of post-industrial areas
and work as:
- soil-creating material
- sludge reclamation
material
The basic version of Izoling mass can be enriched with
varying amounts (depending on application) of additional components,
such as absorbers, fertilisers, seed compositions, cuttings, etc.,
enabling matching the mass properties to soil properties such as
hygroscopicity and granularity.
The Izoling mass can also be
used in reclamation of industrial sludges. Very good effects can be
obtained by covering the sludge surface with mats (quilts) of
Izoling stitched with cuttings. These mats are stabilised with
openwork viscose cladding and can be tacked with one another and
anchored to quay, to make it impossible for the wind to move them
over the water surface. Stitched plant cuttings have enhanced growth
capabilities in oxygen-lacking environments and they quickly grow
through the Izoling mats creating oxygen microspheres in the sludge.
Innovative Aspects:
- Method of utilising wastes after
the segregation process, which are not suitable for conventional
recycling, such as wet fibrous and textile materials, wet or dirty
waste paper
- Lowering landfill operating costs by utilising
post-segregation wastes in landfill operation
- Non-conventional
waste utilisation - land reclamation in post-industrial areas
-
Utilising alternative material for daily waste separation
-
Elongation of landfill working life by decreasing of daily waste
separation material volume
Main Advantages:
- The
Izoling mass, together with plant seeds constitutes a ready-for-use
biologically active material.
- Izoling absorbs deposits:
exhalations (hydrogen sulphide, mercaptans).
- Izoling can be
spread over a landfill, or a degraded terrain to be reclaimed, using
the splashing method.
- The cost of using Izoling is competitive
when compared to other isolating materials, e.g. sand, soil or
synthetic foams.
- Izoling does not suffer any damage from
mechanical impact of landfill machinery.
- Izoling is resistant
to atmospheric influence.
- Due to the fact that Izoling is
manufactured from materials selected directly from municipal waste
it is estimated that using it in a landfill shall lower its
operating costs by about 30 %, at the same time extending its
working life by about 20 %.
- Using Izoling as a layer
protecting municipal landfill instead of making conventional
inter-layers, makes it possible to gain additional landfill volume
due to thinner separating layer and making the material directly
from the wastes disposed.
- When a conventional 20 - 30 cm thick
inter-layer of native material is compared to a 3 - 5 cm thick
Izoling layer, the volume gain is in the range of 25 - 30 %.
Currently Izoling is the cheapest landfill waste protection
material, at the same time stimulating selective waste collection.
- Izoling, additionally equipped with seeds or vegetative plant
cuttings, enables quick reclamation of waste land, the reclamation
of which by traditional method of fertilisation with humus is not
only very expensive, but often difficult or impossible due to
washing away of soil, e.g. from heap slopes, and difficulties in
sludge seeding.
