In 2016-2021, coffee consumption in Indonesia was predicted to increase by 120,000 tons, impacting the increase of coffee waste. Several large coffee industries in Indonesia are located in Taman District, Sidoarjo Regency. The character of the coffee skin waste contains 44.87% organic C; N of 1.69%; P of 0.18%; K 2.49%, and C / N ratio 10-14. This value indicates that the waste can be used as compost because it meets the criteria in SNI 19-7030-2004 concerning Compost from Organic Waste. This narrative review aims to determine the circular economy of bio compost from the coffee industry solid waste to support SDGs point 1 in alleviating poverty in communities around the Sidoarjo coffee industry. The research results showed bio compost I and II is the alternative product in the circular economy (W11). The coffee waste, coffee ground, coffee skin, and coffee returned collects waste in the circular economy (W10). The raw material composition of Bio compost I such as 1.5 kg coffee ground: 1.35 kg of coffee returned:0.15 kg coffee skin+3mL of EM4 and Bio compost II such as 4.6 kg SCG's:0. 4 kg coffee skin+5 ml EM4. In practice, the circular economy of bio compost I and II can involve Farmer Groups or Youth Organizations around the industry in Taman District, Sidoarjo Regency. Based on data 2020, the total members are 113 people, producing compost of 72,435.5 kg/month with a sales profit of IDR 36,217,750. This practice can support the first point of the SDGs, namely poverty alleviation for communities around the coffee industry. However, studies on the exact circular economy pattern of coffee waste in the Sidoarjo Regency are still needed.
