成果简介	NOVELTY - Method for recycling multi-layer plastic (MLP) waste involves shredding multi-layer plastic into fine particles, mixing the shredded multi-layer plastic with a chemical composition, which comprises calcium hydroxide (Ca(OH)2), sodium chloride (NaCl), magnesium oxide (MgO), nitrogen, potassium oxide (K2O), and phosphorus pentoxide (P2O5), heating the mixture at a temperature range between 80-120 °C through extrusion, and producing a solid material with a gross calorific value (GCV) of 7700 kcal/kg or higher, suitable for use as a solid fuel. USE - Method for recycling MLP waste to produce high-energy solid fuel. ADVANTAGE - The extrusion process is carried out at a temperature that prevents the emission of harmful gases, ensuring no significant air pollution. The solid fuel product is capable of combustion in furnaces at temperatures of 1200 °C, ensuring complete combustion without residue. The method allows for the recycling of polyethylene, polypropylene, and aluminum foil materials without the need for separating the layers. The reactive agents enhance the calorific value and overall performance of the final product, where their combination improves the processability and fuel efficiency of MLP waste during extrusion. The plasticizers improve the flexibility of the solid fuel product. The fillers enhance the mechanical strength of the final solid fuel product. The addition of potassium chloride (KCl) or calcium chloride (CaCl2) maintains the stabilizing and processing benefits. The calorific value of the high-energy solid fuel product, i.e., 7700 kcal/kg, makes them a superior alternative to conventional solid fuels. The inclusion of MgO, nitrogen, K2O, and P2O5enhances the calorific value and overall performance of the fuel. This recycling process minimizes harmful emissions and reduces environmental impact, offering a sustainable and efficient solution to the MLP waste problem. The manufacturing process is designed to have minimal environmental impact, with no emissions during extrusion due to low-temperature processing. The solid fuel produced is an efficient energy source, reducing dependency on traditional fuels like coal. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a chemical composition used in the recycling of MLP waste into solid fuel, which comprises calcium hydroxide (Ca(OH)2) as a binding and reactive agent, sodium chloride (NaCl) as a stabilizing and enhancing agent, magnesium oxide (MgO), nitrogen, potassium oxide (K2O), and phosphorus pentoxide (P2O5) as additional reactive agents to enhance the calorific value and overall performance of the final product, where the combination improves the processability and fuel efficiency of MLP waste during extrusion.
