Hydrothermal liquefaction (HTL) offers a sustainable way to convert Bangladesh’s abundant wastewater sludge and lignocellulosic biomass into valuable biocrude. This study proposes a novel multistage co-HTL process to enhance middle distillate production, providing an alternative to fossil fuels while supporting national sustainability goals.

Urban informal settlements struggle with inadequate WASH services due to dense, unplanned layouts and socio-cultural constraints. This research proposes a socio-spatial WASH model that combines spatial analysis with user preferences to optimize facility placement and enhance accessibility, safety, and community acceptance. Focusing on Khulna, Bangladesh, it aims to improve living conditions and guide effective interventions for vulnerable communities.

Faecal sludge management remains a major challenge in low- and middle-income countries, where conventional anaerobic digestion is limited by slow degradation, poor pathogen removal, and scalability issues. This research proposes Quick Digestant of Faecal Sludge (QDFS)—a blended product combining enzymatic pre-treatment, co-digestion principles, deodorants, and disinfectants—to accelerate sludge breakdown, reduce odors, eliminate pathogens, and improve on-site treatment. QDFS aims to offer a cost-effective, scalable solution that enhances public health and reduces environmental risks in underserved communities.

This research investigates anaerobic co-digestion of tannery fleshing and fecal sludge as a sustainable waste-to-energy solution for Bangladesh. By optimizing substrate ratios and operational conditions, the study aims to enhance methane production while reducing waste volumes and environmental pollution. The findings could support circular, energy-efficient practices in industrial zones such as the Savar Tannery Estate.

This research explores using carbonized fecal sludge as a raw material for brick production in Bangladesh. By incorporating treated FS into clay bricks, the study aims to reduce environmental pollution, stabilize harmful waste, and create lightweight, durable construction materials, promoting a circular economy and sustainable waste management.

This research compares three willingness-to-pay (WTP) techniques—Discrete Choice Experiments, Contingent Valuation, and Hedonic Pricing—to predict sanitation behaviors of landlords and tenants in Dhaka’s urban slums. By analyzing user preferences, socio-economic factors, and tenure dynamics, the study aims to identify the most accurate method for guiding equitable, financially sustainable sanitation programs and advancing SDG 6.

UNICEF Bangladesh and ITN-BUET implemented WASH FIT in 16 HCFs to enhance infrastructure, infection control, and care quality. They conducted workshops, formed teams, and developed improvement plans based on thorough assessments.

ITN-BUET, supported by SNV and the Dutch Embassy, led the “Transitioning to Sustainable Urban Water Cycles in Bangladesh” project to enhance urban waste management in 12 cities. They provided technical expertise for policy and system analysis to improve urban sanitation and waste services.

The major objectives of this research project are to assess the suitability of using fecal sludge and liming sludge for producing agricultural-grade compost, examine the physicochemical characteristics of the compost, and evaluate its seed germination capacity.

The proposed research is expected to develop guidelines for a simple, novel wastewater treatment systems in institutions and/or domestic wastewater treatment in urban, semi urban areas of Bangladesh.
