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.

On Friday 13th February 2026, Makerere University was honored to host Prof. Daniel Branch, the Deputy Vice Chancellor of the University of Warwick. This visit marked a significant follow-up to a 2025 delegation from Makerere to Warwick, emphasizing a growing and reciprocal relationship between the two prestigious institutions. Organized by the Makerere University Research and Innovation Fund (Mak-RIF), the day began with a strategic meeting in the office of the Vice Chancellor, Prof. Barnabas Nawangwe, alongside key university leadership including Prof. Fred Masagazi Masaazi chairperson of Mak-RIF and Mr. Simon Kizito the Deputy University Secretary.

During the initial discussions, Mr. Simon Kizito, reflected on the eye-opening experience of visiting Warwick, specifically praising their forward-thinking approach to industry collaboration and innovation. These observations set the stage for exploring new possibilities for student exchange programs. Such initiatives are envisioned to allow students from both universities to share valuable experiences in research and technology, fostering a global academic environment.

Prof. Nawangwe provided Prof. Branch with an overview of Makerere’s historical significance as the oldest university in East Africa and its immense research capacity, supported by an academic staff holding approximately 1,390 PhDs. He highlighted Makerere’s leadership in technological advancements, citing the design and production of Africa’s first electric car, the Kiira EV. Prof. Nawangwe also addressed the global knowledge gap, noting that Africa currently contributes only 3% of the world’s knowledge. He emphasized that collaborating with institutions like the University of Warwick is essential to increasing this percentage by improving supervision capacity and research impact.

From February 11th to 12th, 2026, the CEDAT conference hall became a hub of innovation as it hosted the Hybrid Renewable Energy Systems Conference. This two-day event marked a significant milestone in the long-standing partnership between BOKU University and Makerere University, a collaboration that has consistently driven major advancements in renewable energy research. The conference served as a platform to celebrate these achievements while charting a course for future technological breakthroughs.

The event was officially opened by the Vice Chancellor of Makerere University, Prof. Barnabas Nawangwe, who emphasized the critical role of electricity in national development. Drawing a comparison to his observations in Austria, where electricity is universally accessible, Prof. Nawangwe noted that the lack of widespread energy access in Uganda remains a significant barrier to technological learning. He reaffirmed Makerere University’s commitment to being at the forefront of solving these energy and technological challenges to better serve the nation.
