| Title | Closed loop bioeconomy opportunities through the integration of microalgae cultivation with anaerobic digestion: A critical review |

| Abstract | Bioenergy and bioproduct production can support energy -environment nexus that leads to a sustainable closedloop economy. Particularly, manure management can be a very demanding, expensive and potentially limiting issue for livestock/poultry operations, especially in cold-regions. Clear steps must be taken towards sustainable nutrient management, reuse and recycling to add a source of income for farmers and improve environmental agricultural sustainability. Integration of clean-technologies, such as anaerobic digestion and microalgae cultivation, is essential to concentrate and recycle nutrients from fertilizers, reuse all manure fractions, and capture new value. This review aspires to (i) provide comprehensive information on integration potential of microalgae into a growing biogas industry, (ii) identify opportunities and challenges, (iii) review potential bioproducts prospect, and (iv) examine life-cycle and techno-economic assessments suitable for cold regions. Such integration can harness the huge untapped potential of the biogas-industry in a way that embraces the region-based circular economy and supports sustainable development goals. |
