School-based waste management is an approach being developed by PT\nAmman Mineral Nusa Tenggara (AMMAN) to strengthen environmental\neducation in West Sumbawa Regency. Through the School Waste Management\nProgramme (PPSS), thousands of students are involved in managing organic\nwaste, which is processed into valuable compost while promoting the\napplication of a circular economy.<\/p>\n
The programme combines environmental education, infrastructure\nprovision, and circular economy practices within the school environment.\nTeachers integrate waste management materials into lessons, whilst\nstudents practise sorting and processing waste using the principles of\nreduce, reuse, and recycle (3R), enabling schools to develop into\nenvironmental learning centres that also involve families and the\ncommunity.<\/p>\n
In its implementation, students and teachers process organic waste in\na \u2018Rumah Kompos\u2019 (Compost House) to produce POSTA, or \u2018Our School\u2019s\nOrganic Fertiliser\u2019. The compost is used for school needs, the\ncommunity, the agricultural sector, and reclamation activities in\nAMMAN\u2019s operational areas.<\/p>\n
Vice President of Policy & Permitting and Social Impact at AMMAN,\nPriyo Pramono, stated that through PPSS, the company aims to strengthen\nthe role of schools as centres of knowledge transformation whilst\nencouraging changes in community behaviour towards waste management.\n\u2018With this programme, AMMAN is helping to build an ecosystem that\ndevelops a future generation of young people who are responsible towards\nthe environment. The success of PPSS is not only seen from the amount of\nwaste managed, but from the growing awareness that waste has value if\nmanaged properly. When that understanding grows among students,\nteachers, and families, the impact extends from schools to the\ncommunity,\u2019 Priyo said in a statement on Tuesday.<\/p>\n
Since its inception in 2022, PPSS has grown from two pilot schools to\nsix active schools, involving thousands of students, teachers, parents,\ncommunity members, and dozens of AMMAN employee volunteers. Over the\nperiod from 2022 to 2025, the programme successfully managed more than\n150 tonnes of organic waste and produced over 50 tonnes of POSTA\ncompost. PPSS also helped avoid around 11 tonnes of emissions in 2025\nand recorded a Social Return on Investment (SROI) of 4.09, meaning every\nRp1 invested generates Rp4.09 in social, economic, and environmental\nvalue.<\/p>\n
AMMAN noted that this school-based waste management model has begun\nto be independently replicated by several schools outside the programme\nwithout company funding support. Several partner schools have also won\nAdiwiyata awards at the provincial and national levels in recognition of\ntheir implementation of environmental management in schools. For its\nimplementation of PPSS, AMMAN received the Waste Management category\naward at the Lestari Awards 2026. The award was given for a waste\nmanagement approach that integrates environmental education with a\ncircular economy and is considered capable of creating sustainable\nsocial, economic, and environmental impact.<\/p>", "url": "https:\/\/jawawa.id\/newsitem\/amman-engages-thousands-of-students-in-school-waste-management-1785326070", "image": "" }, "sponsor": "Okusi Associates", "sponsor_url": "https:\/\/okusiassociates.com" }
