The total amount of waste produced by Indonesia in 2020, reach 29 million tons. Of this total amount of waste, the average amount of household waste produced by Indonesia in 2021 was large, reaching 42.33%. This data has been reduced after previously in 2020, the total waste in Indonesia reached 67.8 million tons. The government's efforts to reduce the amount of waste include the establishment of a waste bank, the development of composting, waste sorting, 3R TPS, and converting waste into energy sources. Household waste is not only produced by the home but also by universities.

In order to overcome this and also to meet the SDG 12 target, namely sustainable consumption and production, Universitas Airlangga is trying to reduce household waste generated by managing their waste. Through the SOP for waste management, Universitas Airlangga emphasizes several things, such as: campus cleanliness is the responsibility of the entire academic community; the entire academic community must dispose of waste in the provided place; waste must be sorted according to type; officers collect and transport waste regularly according to the daily schedule and regulate the process; and composting according to the volume of waste generated.

Universitas Airlangga itself produces 400 kg of waste each month, which is then sorted for later processing into compost. Meanwhile, 350 kg of waste is processed every month to be used as compost to meet the fertilization needs of the university. The waste that is processed into compost itself has gone through several processing stages and is divided into several storage tanks before finally being circulated to be used for fertilization in the university environment. At the initial stage, the waste is collected into tank I. A process occurs with the characteristics of waste with a water content of 5-20%, with a pH of 4-5 or the waste still tends to be acidic. Entering the second stage in the reservoir II, the waste has a water content of 10–25% with a PH of 5–6. Intensive decomposition occurs, which means that there is a change in the structure of the waste. Next, entering the third stage, the waste collection tank III has a moisture content of 15-25% with a PH of 6-8. At this stage, the main maturation of the waste to become compost occurs. At this stage, the compost is ripe and fresh. In the final stage, namely the fourth stage, the IV garbage collection tank has a moisture content of 15–25% with a PH of 9, or the compost starts to become alkaline. Compost at this stage tends to be ripe but still wet.
