Coffee Waste Management Using Valorization Technology: Potential Development of Eco-Industrial Park in Jember Regency, Indonesia.

In Indonesia, the coffee agroindustry is making a significant economic contribution, with some environmental issues, including water pollution, eutrophication, and greenhouse gas emissions. This agroindustry generates vast by-products, offering a potential opportunity for material and energy recovery through eco-industrial parks. Therefore, this study aimed to analyze coffee waste management through valorization technology and the potential development of a coffee-based eco-industrial park. A system engineering approach was employed using a case study of the coffee agroindustry in Jember Regency, Indonesia. The result showed suboptimal utilization of technological valorization, as only 15% - 20% of the total solid waste was effectively valorized, resulting in low economic added-value of the products produced. This condition was caused by several factors, such as insufficient knowledge about valorization technology, inadequate availability of technological equipment, and the absence of a well-established market share of added-value products from coffee waste. Furthermore, the coffee-based eco-industrial park (EIP) design identified three main functionalities and its environmental operating systems. The coffee-based EIP could be potentially improved through public-private partnerships and broadening the scope of valorized coffee waste, including spent coffee grounds and wastewater.
