Waste and Food Waste Management Policy at UNS as an Effort to Reduce Landfill Waste and Increase Recycling
The high volume of waste in the university environment poses a significant challenge for sustainable environmental management. In response to this issue, Universitas Sebelas Maret (UNS) issued Rector’s Instruction Number 30 of 2023 on the Management of Waste and Hazardous and Toxic Materials (B3), which not only regulates the management of hazardous waste but also emphasizes the importance of controlling the flow of waste to the landfill and optimizing recycling programs. This instruction mandates the separation of organic and inorganic waste, promotes waste reduction programs through the principles of reduce, reuse, recycle, and composting, and imposes restrictions on the use of single-use materials such as plastic, paper, and styrofoam. With this policy, UNS has a foundation to measure and reduce the amount of waste sent to landfills, while also increasing the volume of recyclable materials that have economic value and do not harm the environment.
As a more specific follow-up regarding food waste, UNS issued Circular Letter Number: 2300.1/UN27/HK.06/2023 on the Measurement and Processing of Canteen Food Waste within UNS. This circular mandates the measurement of food waste in all UNS canteens before processing, as part of the university’s efforts to adapt to the impacts of climate change. The measurement aims to obtain accurate data on the volume and type of food waste generated, which will then serve as the basis for formulating more effective and measurable waste reduction policies. Through this step, UNS ensures that waste management not only reduces the amount of waste sent to landfills but also increases the volume of materials that can be recycled or composted.
This policy has yielded tangible outcomes, including the establishment of waste sorting and management facilities, as well as the active involvement of the university community in sorting and reducing waste at its source. The expected outcome is the creation of a cleaner and more sustainable campus ecosystem, while making a real contribution to reducing the burden on Surakarta City’s landfill.

Affirms the obligation of all work units within the campus to manage waste and hazardous materials in an integrated manner. This policy includes reducing waste generation based on the principles of reduce, reuse, recycle, and composting, as well as banning the use of single-use plastics and styrofoam. It also involves managing laboratory and hazardous waste (B3) from sorting, storage, and transportation to treatment through the Integrated Wastewater Treatment Plant (IPAL). |

Circular Letter Number 2300.1/Un27/Hk.06/2023 on the Measurement and Processing of Canteen Food Waste within Sebelas Maret University |
UNS is making efforts to adapt by minimizing the risks and vulnerabilities of the campus community in the face of climate change impacts, one of which is through waste management based on the concepts of reduce, reuse, recycle, and composting. Based on this, food waste measurements are conducted in all UNS canteens, and the waste is processed. |
RELEVANT RESEARCH
In the framework of SDG 12, UNS encourages research that supports responsible waste management. The research “Pengembangan Usaha Batik Ecoprint pada UMKM Soloecoprint.id Melalui Peningkatan Kualitas Produksi Corak Pewarna Alam” by Prof. Dr. Sayekti Wahyuningsih, and “Diversifikasi Produk UMKM Dewi Batik Boyolali melalui Penerapan Teknik Batik Cap Kertas dan Pewarnaan Alami untuk Pengembangan Motif Batik Simplicity” by Prof. Dr. Sarwono, demonstrate practices that reduce hazardous waste and minimize landfill use. The use of natural dyes and paper-based batik techniques produces less harmful residues, aligning with the university’s policies for proper waste disposal.
