The world is currently undergoing a paradigm shift towards a circular society in which resources are recovered and reused rather than discarded. The global population has surpassed seven billion people, and rapid urbanisation in many areas is putting a significant strain on our ability to provide basic services to all. The Sustainable Development Goals highlight the fact that millions still lack access to food, healthcare, water and sanitation. At the same time, it is increasingly evident that we are consuming the Earth’s resources and releasing waste into the environment in an unsustainable manner. The resulting effects on climate change, biodiversity loss and changing nutrient cycles threaten to over-step critical planetary boundaries. Crossing these boundaries has the potential to cause irreversible environmental change and to threaten the ability of humanity to develop and thrive. Sanitation systems manage carbon, nutrient and water flows, which are key resource flows that affect the planetary boundaries and thus should be recovered and recirculated instead of being released into the environment. Increasing resource recovery within our sanitation systems can play a critical role in shifting to a more sustainable society.

There are significant resources within excreta and wastewater fractions that can be recovered and turned into useful products. For example, the average person excretes 4.5 kg of nitrogen, 0.5 kg of phosphorus and 1.2 kg of potassium every year. These elements and other micronutrients found in excreta are critical for the fertilising and restoration of agricultural soils. The energy value of faeces is on average 4 115 kcal/kg of dry solids. This energy can be utilised as a renewable energy source. On top of this, there are large volumes of wastewater that can be captured, cleaned and reused. However, human excreta and wastewater contain pathogens and other undesired substances, risks that need to be managed in a reuse system. The growing demand for recycling needs to be complemented with a growing knowledge of how to do it safely.

The aim of this document is to provide an overview of the possibilities for resource recovery from sanitation and provide guidance on treatment processes to achieve safe products for reuse. The focus of this document is on resource recovery from the organic wastes managed in sanitation systems and, to a lesser extent, on the recovery of water and energy generation. Resource recovery sanitation systems are defined as systems that safely recycle excreta and organic waste while minimising the use of non-renewable resources such as water and chemicals. Safe recycling means that waste flows are managed so that physical, microbial and chemical risks are minimised. Thus, the recycled product should not pose any significant health threat or environmental impact when correctly used.

The specific objectives of this document are:

To expose the user to a broad range of recovered sanitation products and innovative treatment technologies.
To help the user to design functional solutions for resource recovery by illustrating the linkages between sanitation inputs, treatment technology and the recoverable products.
To provide an overview of basic information regarding design aspects, operational requirements and health, safety and social considerations related to resource recovery technologies and products.
Describe and fairly present technology-specific advantages and disadvantages.

Students and staff from the College of Engineering, Design, Art and Technology (CEDAT), Makerere University have completed one week of intensive fieldwork in the Manafwa Catchment, Eastern Uganda, under the DIGITWATER Project.

According to Dr. Jotham Sempewo, the Principal Investigator based at CEDAT, since March 2, 2026, students and staff conducted field activities in the Manafwa River Catchment, collecting critical data on hydrology, water quality, irrigation agronomy at the Doho Irrigation Scheme, and exploring nature-based solutions. The findings, he observed, will inform practical strategies for improved catchment management

The project coordinated by Vrije Universiteit Brussel (VUB) brings together 10 partner organizations from Europe and Africa, and is focused on designing innovative and sustainable solutions for water resources management.

CEDAT Acquires New Executive Bus to Enhance Mobility

The College of Engineering, Design, Art and Technology (CEDAT) at Makerere University has officially added a brand-new executive bus to its fleet, a milestone that underscores the institution’s commitment to improving mobility and efficiency for staff and students.

The 41-seater bus, valued at UGX 500 million, received Monday March 9, 2026 is a product of Kiira Motors Corporation. It is equipped with modern features designed to ensure comfort and safety during travel. This acquisition will significantly reduce the logistical challenges previously faced in arranging transportation for official trips and academic activities.

Prof. Moses Musinguzi, Principal of CEDAT, received the bus from Mr. Tonny Seruyange, Transport Officer at the Directorate of Estates and Works. Speaking at the handover, Prof. Musinguzi expressed optimism about the impact of the new bus:

“This addition will greatly improve our mobility and coordination, easing transportation challenges and fostering greater efficiency in our operations. It is a step forward in supporting our academic mission and enhancing the experience of both staff and students.”

The new bus represents a strategic investment in infrastructure that strengthens Makerere University’s ability to deliver on its academic and institutional goals.
