Abstract

This study aims to analyze the effect of borax as a flux on the melting performance of recycled 3004 aluminum from beverage can waste. The melting process was carried out using an oil-fueled furnace with six borax variations, ranging from 2.5 g to 15 g for 500 g of recycled aluminum. The results showed that the net aluminum mass increased from 209 g to 293 g, while the slag mass decreased from 242 g to 139 g. Linear regression analysis revealed a positive correlation between borax and net mass (R² = 0.9116) and a negative correlation between borax and slag (R² = 0.9135). Therefore, borax proved effective in increasing the yield of clean metal and reducing slag during the recycling of aluminum.

Abstract

Polymers are the result of monomer polymerization with a lower density than metals but a much smaller elastic modulus, making them less rigid and strongly affected by temperature. This study evaluates the performance of a laboratory-scale crushing machine for polypropylene blended with activated carbon at varying compositions. The machine employed carbon steel rotary blades driven by a 1 HP electric motor through a gearbox transmission. Results showed average crushing times of 3.5–4 minutes/kg. Pure polypropylene produced a 72% fine fraction, while adding 10% activated carbon reduced it to 65%. Crushing efficiency remained above 85%, demonstrating stable performance and feasibility for composite material applications.
