Plastic is essential part of our life. Due to its usefulness, it has become integral part of almost each sector. With number of advantages associated, one of the major limitations is its non-degradable property. Today more than 60% of our plastic waste is still dump in to the landfill.
The machine effectively reverses the plastic production process, where the Thermo Catalytic Depolymerization (TCD) process cracks the long chains of polymer to produce useable fuel. The waste plastic is cleaned and shredded into small pieces before Thermo Catalytic Depolymerization (TCD) process, to remove contaminants like paper, oil, grease, food particles etc. This is important as it increases the efficiency of the machine and subsequently quality of the fuel. During the startup, depending on the availability the natural gas/ LPG or the diesel is used. During the process, the heat output monitored to maximize the consistency of the fuel. The process is a batch type process, which takes between 3 to 7 hours to complete depending on the capacity of the machine
The Thermo Catalytic Depolymerization (TCD) process : performed within a heated sealed reactor. The reactor is loaded with the shredded plastic and is heated and the catalyst helps in cracking the long chains of polymers in the absence of oxygen to produce hydrocarbon vapors. The plastic depolymerized at 380 – 430oC, and the gases are condensed. The condensed vapor produces the fuel and synthetic gases, out of which the syngas used as an energy source for the further heating of the reactor. This synthetic gas, which is a byproduct is passed through scrubber and cleaned prior to being used a heating source; helping improve the efficiency of the process. The fuel passes through the filtration system before it’s collected. The Non-plastic material and non-depolymerized plastic settles at the bottom of reactor, collected after the shift or during weekly maintenance.
Depolymerization : Depolymerisation is the process of molecular decomposition when large molecules split into the smaller molecules. The waste plastic is converted into usable end product : synthetic oil, gas and carbon. Depolymerisation is thermo-catalytic decomposition or cracking of polymers in absence of oxygen. Depolymerisation process is pollution free. There are no harmful gases or effluents generated in the process.
The machine converts waste plastic into fuel and cleaned synthetic gas. The exact recovery ratio and characteristics of the fuel varies depending on the types of plastic received.
Each ton of plastics produces approximately
As a result, a key advantage of this process is that the plastic wastes do not need to be pre-sorted, cleaned or dried prior to processing, which in turn significantly reduces the overall cost of operation.
