ABSTRACT

Prior to the recent conflict, rapid industrial growth in Tigray, Ethiopia, fueled significant environmental degradation. This expansion led to the overexploitation of natural resources and increased pollution stemming from chemical effluents, wastewater discharges, and the accumulation of solid waste. This unsustainable trajectory necessitates a fundamental shift towards a circular economy model to mitigate environmental damage, promote resource conservation, and ensure long-term ecological and economic resilience. The transition requires a departure from linear 'take-make-dispose' practices towards closed-loop systems focused on resource recovery, reuse, and waste valorization.

The findings of this study aim to illuminate actionable pathways for transitioning Tigray's industrial sector to a circular model, focusing on practical solutions for valorizing waste, promoting resource recovery, and enhancing sustainability. The study will provide a detailed initiative map to guide the implementation of identified circular economy strategies by industrial actors, policymakers, and community stakeholders. The study will contribute significantly to the development of a regional waste management policy and contribute to a more sustainable and resilient industrial sector.

Focusing on ten industries in Tigray, this study explores a circular economy framework for managing industrial waste streams. It investigates innovative strategies for converting these waste streams into valuable resources, including livestock feed, irrigation water, construction materials, and agricultural fertilizers. Additionally, it addresses the need of zero waste discharge and valorization of waste, sludge and energy recovery. In conclusion, the study evaluates the environmental sustainability of these approaches and presents a comprehensive initiative map for the implementation of circular economy principles within Tigray's industrial sector. The recommendations aim to inform policy decisions and facilitate the transition to a more resilient and sustainable industrial economy in Tigray.
