Plastic and rubber products considered of being a great importance to humans, but
their residues and wastes are a real environmental disaster. They are dumped in fields,
streams and forests or buried in large landfills that pose a serious hazard th
at needs to work
on solve it in the best possible way.
On the other hand, the economic problems caused by the erosion of concrete cement
have made it the major problem of infrastructure in the industrialized countries. Over the
past three decades, this problem has reached alarming proportions, which led to high repair
costs, whether in concrete or in reinforcing steel, Especially acidic media due to concrete
permeability of acid rainwater, where these costs exceeded initial construction amounts in
some cases.
This paper deals with the recycling of used tires and some types of plastic waste to
be used in the preparation of insulating materials for water and heat at a low cost compared
to the insulation materials currently used in the construction process, in addition to the
preparation of floor tiles for internal and external use.
studying the recycling of bituminous pavements
is important to achieve a set of objectives. The most
important one is to examine the asphalt obtained from the
recycled bituminous pavements in order to identify its
properties and suitability for reuse according to its
serviceability, reductions and cost benefit.
This research demonstrated a way to study the thermal properties
of raw and recycled High Density Polyethylene HDPE which is
used to make oil containers. Also, the research has dealt with the
effect of recycling on blow molding process used to manufacture
these containers.
In the present paper, we study the effect of both morphology and
compatibilization on the reaction to fire of blends of recycled
poly(ethylene terephthalate) (PET) with recycled polycarbonate (PC).
This paper presents an experimental study to determine the physical and
some other important properties of certain waste materials, in order to
identify the appropriate field of their recycling. The experiments have
been carried out using five proposed materials, namely: corn cob, peanut
peel, straw, pine cone, and sticks of the stem Thistle Syrian plants.
A synthetic fibre from polyolefins wastes was obtained as follow:
1. From polyethylene and polypropylene wastes in various
percentages to get the optimum percentage in the fibre
2.From polyethylene and polypropylene gralunar.
We used an indirect
recycling operation using extrusion by the
extruder.
The obtained fibre was tested mechanically, physically and
chemically and the results demonstrate that the production of these
fibers are available laboratorially and industrially.
