(An Effective Product Based Solution to convert Waste Plastic into Energy)
Need of the Hour
Twenty per cent of municipal waste is non-biodegradable plastic, which currently ends up in landfill, thereby creating pollution. With the relentless problem of landfill site locations continuing to present difficulties to councils and waste collection agencies, the single biggest cost of waste management today is transport. Many councils are now forced to pay huge rates per ton simply to move the waste out of the collection areas and into the landfill sites.
Although many methods such as incineration and recycling are there, but they have again some drawbacks and cause pollution. To overcome this problem a new technology has been developed for their better disposal.
The Present Scenario
Various methodologies have been tried and tested to process waste plastics for many years, with recycling becoming the most common methods, reflecting the needs of the time. Plastics that cannot be processed are handled by waste management companies by land filling or incineration in recent years, building or expanding of incinerators has become difficult due to the opposition from governments and community groups with environmental concerns, most notably the level of the emissions.
Liquefaction of plastics is the superior method of reuse of the resource. The distillate product is an excellent fuel and makes Pyrolysis is one of the best, economically feasible and environmentally sensitive systems in the world today. Pyrolysis fuels are used as fuel for diesel burners, trucks, agricultural pump sets and generators.
Pyrolysis is a process whereby, scrap and waste plastics are converted into liquid hydrocarbons that can be used as fuels. The system uses liquefaction, pyrolysis, and breakdown of plastics. The system can handle almost all the plastics that are currently being sent to landfills.
Pyrolysis is the process of thermal disintegration in the absence of oxygen. Plastic waste is continuously heated in a cylindrical chamber and the pyrolytic gases condensed in a specially designed chamber to yield hydrocarbon distillate, comprising straight and branched chain aliphatic, cyclic aliphatic and aromatic hydrocarbons. The resulting mixture is essentially equivalent to petroleum distillate.
ACCEPTED PLASTIC WASTE for conversion:
- Polyethylene(PE) 0.918
- Polypropylene(PP) 0.90
- Polystyrene(PS) 1.04
- ABS resin (ABS) 1.03-1.072
- Plastics recovered from the kerbside collection of recyclables.
- HDPE and LDPE
Not to be Used:-
PET and PVC ITEMS.
1. Product Yield : Pyrolysis system converts these waste plastics into high- grade “Green” distillate fuel. This has proven successful, and is economically viable and a virtually non-polluting, (100%) synthetic fuel which does not require engine modification for maximum efficiency. Pyrolysis process has a production efficiency of over 80% and the resultant diesel output, almost equals the regular fuel.
2. Economics: One tonne of waste plastic will, on an average, produce 500 – 800 liters of diesel fuel, with just 10 – 50 ppm sulphur content
Simply, Fuel output for Every Kilogram of Waste Plastic gives 500 to 800 ml of diesel by consuming 1KW of electricity.
3. Most of the gas is liquefied in the condenser but some remain as Hydrocarbon with carbon count of 4 and lower, remain as gas at room temperature. This off gas contains methane, ethane, propane, butane, etc. Although volume of the gas varies, depending upon the types of plastics, it is usually 20% and almost equivalent to LPG Gas.
4. The carbonaceous char is the residue in the chamber, during the pyrolysis. The char residue produced, is about 2% of the output for the relatively clean polyolefin feed stock.
- Low- Cost Fuel
- Reduction of Waste Plastics
- Ability to handle unsorted, unwashed plastic.
- Energy from Waste.
- Low sulphur Content fuel.
- LPG gas from reaction (By Product), only during process
- Reduce Pollution caused by Plastic Waste.
Chop the Waste Plastics into small size to accommodate into vessel and for saving of heating energy
Coking occurs in the chamber when the pyrolysis of the waste plastics is almost complete. The chamber requires cleaning every second process, and just takes a few minutes. The residue will be around 2% of loaded waste consisting mainly ash, carbon and unconvertible waste.
Items having 2,4,5 and 6 Nos can be used for this process.
