Study of sustainable solid waste management system of Carocok Beach Painan tourism area using Life Cycle Assessment (LCA) method

Abstract

This study aims to assess the environmental impact and compare two scenarios of the solid waste management system of the Carocok Beach Tourism Area using the Life Cycle Assessment method. System boundaries include operational and technical aspects of waste management, the energy required, and emissions generated. The functional unit is 30.546 kg/day of waste treated. Scenario 1 is the existing conditions using a city-scale approach with a 1% reduction of waste at the source by scavengers, using a collection of motorized pedicabs, applying transportation to landfills by arm roll truck, and processing Integrated Solid Waste Treatment Plant by composting and landfilling with controlled landfill operation. Scenario 2 is the planning system with different phases of waste processing at the Recycling Center by composting and recycling with plastic chopping machines, producing handicrafts, and practices of sanitary landfill on landfilling. The impact assessment method uses the CML-IA method. The impact categories studied are Global Warming Potential (GWP), Acidification Potential (AP), and Eutrophication Potential (EP). Scenario 2 showed the best scenario because it has a smaller impact value for the three impact categories. However, to become a more sustainable management system, some improvement options recommended include a substitution of collection and vehicle fuel and waste processing using the Takakura method.
