| چکیده | ||
| The residue produced and left behind under the burning furnace from the burning of infectious waste is a category of hazardous and toxic waste. The residue from combustion contains heavy metals, which can harm the environment and the health of living creatures. Good management must be implemented to reduce the resulting impacts, one of which is utilization. Appropriate utilization can be done by knowing the characteristics of combustion residues both physically and topographically. The main objective of this research is to analyze the physical characteristics of infectious waste combustion residues and topographic composition. Physical characteristics include water content parameters using SNI 03–1971–1990, mud content using the settling method, gradation using the sieve method, specific gravity using SNI 1970:2008, water absorption parameters using oven drying. Topographic composition was analyzed using SEM. The water content obtained in the residue was 9.55%, the mud content was 34.1%, the specific gravity result was 1.82, and the gradation of the ash fell into the zone 2 category, indicating that the fine aggregate tested fell into the medium sand size category, water absorption shows 10.65%. SEM results show the presence of crystalline particles with sharp edges and flat surfaces, as well as amorphous particles that are more irregular and hollow. Utilization can be done on residues from burning medical waste, one of which is as a substitute for sand in the medium category. Utilization can be made into several products that use medium category sand and are given a additives or pozzolan mixture to prevent leaching | ||
