Solid fuels from peanut shell waste briquettes and LDPE, PP, and Biodegradable plastics were investigated in this study. Peanut shell charcoal powder is mixed with three types of plastic, each in a ratio of 20 gr: 0.8 gr for each additional type of plastic. The pressing pressure was set at 70 N/m2, the particle size was set at 60 mesh, and each plastic was chopped to a size of (0.5 x 0.5) cm. The starch binder used was 2 gr for each sample. The result of the investigation found that the addition of the type of plastic had a significant effect on the physical and chemical characteristics of briquettes. The highest modulus of elasticity value for briquettes, namely 20 MPa, and the highest compressive strength value for briquettes, namely 4.45 MPa, were obtained from a mixture of peanut shell waste and biodegradable plastic. For the chemical properties of briquettes, the highest calorific value of briquettes is obtained from a mixture of peanut shell waste and PP plastic of 6185 cal/gr, the lowest moisture content is obtained from the addition of LDPE plastic of 7.71%, the lowest ash content is obtained from the addition of biodegradable plastic of 4.01%, the lowest volatile content was obtained from the addition of PP plastic of 15.71%. The most deficient fixed carbon was obtained by adding biodegradable plastic of 78.50%.
