Raw Materials

Raw materials that the process is capable of processing can come from various sectors of the industry including but not limited to information technology, crude oil processing, electronics, food industry, chemical industry, construction industry, cosmetics industry or pharmaceutical industry.
Wastes, i.e. raw materials are primarily polyolefin, like polyethylene (PE) or polypropylene (PP). The scale of recyclable wastes is broad including both the products we use every day and those used for special purposes.
Examples of raw materials the plant is capable of handling are but not limited to the following:-
-
One-time used PP bags and sacks;
-
Packaging of detergents and cosmetics;
-
Packaging of food;
-
Parts of household gadgets;
-
Radio/television parts;
-
Toys;
-
Parts of computers/office equipment;
-
Parts of storage boxes/tanks/pipes made of plastics, cable insulations;
-
Industrial fabrics;
-
Vehicle parts (e.g. bumpers, dashboards, battery cabinets)
.
Note:-Only scraps components made from PP/PE/LDPE/HDPE.
Examples of Plastics not suitable for the Pyrolysis process:-
.
-
Thermo setting plastic.
-
PVC,poly carbonates
-
Thermosetting resins
-
Nitrogen, sulfur & Carbonyl group polymers.
Raw materials used in the described process shall meet the following requirements in order to enable the end product meet applicable quality standards.
In order to achieve the highest possible quality the utilization of raw material that contains broad range of polyolefin plastic wastes should necessarily be used.
Examples are:-
Polyethylene (-CH2-CH2-) n - industrial mark is (PE)Polypropelene (PE)
-
(High density PE) – HDPE, Numeric code 02;
-
(Low density PE) – LDPE, Numeric code 04;
-
(Linear is, Low density PE) – LLDPE
Maximum Acceptable impurities:-
-
Mineral pollution below or equal to 5 percent (incl. sand, dust, glass, minor metallic particles Calcium Carbonate or other fillers));
-
Moisture below or equal to 10 percent;
-
Printed legend on plastic packaging;
-
Different color/structure/thickness packaging materials;
-
Various used PE or PP products;
-
PE or PP products mixed in different extent;
-
Aluminum coated PE/PP films.
Not Acceptable:-
-
Any other pollution/contamination or other organic composition which includes chlorine, (halogens), nitrogen, Sulphur and carbonyl group.
(Excellent quality of end product can only be ensured if the raw material meets the pollution requirements specified.)
• POLYETHYLENE /POLYPROPYLENE: Polyethylene is a product of ethylene polymerization. Examples are packaging, bags, insulations, cables, acid-resistant wires, construction industry or chemical industry applications, toy components, or components of household gadgets.
Polypropylene (-CH2-CH(CH3)-)n – (PP), ,Numeric code 05; Atactic, iso-tactic, syndic-tactic. Polypropylene is a product of propylene polymerization. Given the fact that it can resist high mechanical loads and extreme weather conditions they are used by chemical industry or food industry in the manufacture of cables, packaging materials or various other products.
EXPECTED YIELDS :Provided the raw material contain less than 15% impurities yields would be:-
-
72.25% - Pyro Oil , 12.75% Hydrocarbon Gas ,( Lower if plastics contain fillers)
-
5 % Residual Carbon ( Higher if plastics contain fillers)
-
10% Moisture loss.
