Organic Waste Treatment / Resource Recovery and Landfill Specialist – Tanzania

Aninver Development Partners SL (www.aninver.com) is looking for a Organic Waste Treatment / Resource Recovery and Landfill Specialist for a consultancy assignment financed by United Nations / UN-Habitat in Tanzania.

Aninver Development Partners SL is preparing a proposal for a consulting assignment supported by the United Nations / UN-Habitat in Tanzania. The initiative focuses on enhancing integrated solid waste management infrastructure, climate resilience, and resource recovery in the country's largest metropolitan area. We are seeking an expert Organic Waste Treatment / Resource Recovery and Landfill Specialist to join our multidisciplinary team for this vital urban development initiative.

The assignment delivers comprehensive upstream technical, environmental, and financial analyses to support the diversion of organic waste from disposal sites. The core aim is to establish scalable circular economy solutions—including composting, anaerobic digestion, and sanitary landfill gas management—that reduce greenhouse gas emissions, improve operational efficiency, and generate marketable recovered products within the metropolitan solid waste sector.

Aninver is preparing a proposal for this assignment. The selected expert will be part of the proposed team; the engagement is conditional on the contract being awarded to Aninver. The full Terms of Reference for the position are shared with shortlisted candidates.

Objectives of the assignment

• Establish a robust baseline understanding of organic waste generation, composition, seasonal variability, and contamination levels across various source segments in the metropolitan area.
• Identify, evaluate, and design suitable organic waste treatment technologies, such as composting and anaerobic digestion, aligned with local conditions.
• Assess the market potential, quality standards, and viable business models for recovered products including compost, digestate, biogas, and energy.
• Evaluate the environmental, climate, and financial performance of various waste diversion scenarios, focusing on methane avoidance and life-cycle greenhouse gas impacts.
• Develop actionable implementation pathways, preliminary design concepts, and integration strategies for pilot projects and future sanitary landfill infrastructure.

Scope of work

• Conduct an inception phase, review existing background documentation, and perform mandatory site visits to legacy disposal areas, transfer stations, and major organic waste generation points.
• Quantify municipal solid waste generation and isolate organic waste fractions, assessing moisture characteristics and high-yield diversion opportunities.
• Evaluate potential siting, processing technologies, and integration options for centralized and decentralized organic waste treatment facilities.
• Analyze waste collection, transfer, and transport logistics to optimize resource recovery and minimize long-haul greenhouse gas emissions.
• Formulate recommendations for public-private participation models, institutional frameworks, and operational capacity-building for local authorities and operators.
• Prepare technical reports, design basis memoranda, and implementation roadmaps in collaboration with key national and municipal stakeholders.

Your role as Organic Waste Treatment / Resource Recovery and Landfill Specialist

• Lead the assessment of organic waste treatment systems, including composting, anaerobic digestion, and related valorization pathways.
• Evaluate feedstock quality, seasonal variability, contamination levels, and treatability across different municipal waste generation sources.
• Conduct technical feasibility analyses for organic waste processing facilities and their integration with planned transfer stations and sanitary landfill infrastructure.
• Collaborate on evaluating landfill gas management options, including flaring or energy recovery potentials at disposal and rehabilitation sites.
• Contribute to the development of preliminary design concepts and operational guidelines for pilot organic waste projects.
• Assist in assessing environmental and climate performance indicators, particularly regarding methane avoidance and organic waste diversion targets.
• Participate in stakeholder workshops, technical meetings, and consultations with municipal authorities and relevant sector institutions.
