Plastics are one of the most widely used materials, and, in most cases, they are designed to have long
life spans. Since plastic and packaging waste pollute the environment for many years, their disposal is of great
importance for the environment and human health. In this paper, a system was developed to store liquid fuel
from plastic and organic waste mixes without solidification, which then can be used as fuel in motor vehicles and
construction machinery. For this purpose, polyethylene terephthalate (PET), polyvinyl chloride (PVC), and organic
wastes and clay, zeolite, and MCS23-code materials (50% magnetite-%25 calcium oxide-%25 sodium chloride)
were heated in a closed medium at temperatures ranging from 300 to 400°C and subsequently re-condensed. The
study conducted twenty tests, involving various types and rates of plastic and organic materials, as well as different
rates of catalysts. Among these tests, the highest liquid fuel yield (67.47%) was achieved in Test 9, where 50% PVC50% PET waste, 75 g of clinoptilolite, and 500 g of MCS23 waste were collectively used. Notably, Test 12 exhibited
the highest density value (79.8 kg/m3
), while the best viscosity value (2.794 mm2
/s) was observed in Test 2. Across
all samples, flash point values were found to be below 40°C. The most favorable yield point value was recorded in
Test 2 (-6°C). The samples displayed ash content within the range of 0 to 0.01% (m/m)] and combustion heat values
of 35.000> J/g which fall within the standard range. The incorporation of MCS23 with clinoptilolite additives is
believed to have a significant impact on obtaining high-yield products with improved fuel properties.
