In addition, SMAN 14 Bandung is a school with the title of an independent Adiwiyata School with environmental insight, but this school has not paid attention to managing its waste. This study aims to plan waste management with zero-waste approach so that the amount of waste sent to landfills is zero. Calculation of zero waste index (ZWI) was performed for a school scale wherein the results of ZWI were used for evaluation and as a basis for the future planning of solid waste management. Sampling measurements were carried out using the load count analysis method. The waste generated is 37,544 kg/day. With a composition of 13.12% organic, 60.42% plastic, 20.957% paper, 0.36 % metal, and a mixture of 5.14% with a zero-waste index of 0.80, the substitution of material savings of 30.09 kg, the substitution of energy 953.94 MJ, greenhouse effect reduction 26.89 Kg/CO2e, and water-saving -232.02 L. Furthermore, through this planning, the estimation of cost reduction was as much as Rp. 23,315 a day.
