1. The document discusses a research project that aims to develop business models for resource recovery and reuse (RRR) from waste streams like agro-industrial waste, wastewater, and municipal solid waste. 2. The research will analyze existing RRR business cases, identify promising models, and test feasibility of models in different cities with a focus on private sector engagement and profitability. 3. The goal is to develop sustainable RRR business models that treat waste as an asset, generate income, and can work at large scale in low-income countries by closing water and nutrient cycles.
