Guide to Sanitation Resource Recovery Products & Technologies

Published

on

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:

  1. To expose the user to a broad range of recovered sanitation products and innovative treatment technologies.
  2. To help the user to design functional solutions for resource recovery by illustrating the linkages between sanitation inputs, treatment technology and the recoverable products.
  3. 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.
  4. Describe and fairly present technology-specific advantages and disadvantages.

Innovations using low cost locally available materials for point of use water treatment system unveiled

Published

on

The College of Engineering, Design, Art and Technology (CEDAT) conducted a Research Dissemination of two studies aimed at the Development of Materials for point of use water treatment systems.

The investigations were conducted by a team of researchers comprised of P. W. Olupot, H. M. Kalibbala, E. Menya, G.M. Wangi, J. Jjagwe, J. Wakatuntu, M. Turyasingura, R. Walozi, C. Kanyesigye and R. N. Kulabako.

The dissemination event held on Wednesday 29th November 2023 follows the successful completion of two MakRIF supported Research projects namely; Development of rice husk based granular activated carbon for point-of-use water treatment systems and Development of zeolite-based nanocomposite filters for drinking water treatment.

Apac District gains from CEDAT’s Research on Piloting a Rural Broadband Connectivity Model and Efficacious patient management system

Published

on

The School of Engineering at the College of Engineering, Design, Art and Technology (CEDAT) shared findings of research that was conducted in Apac Districts through two projects namely Piloting a Rural Broadband Connectivity Model (RCBM) and Efficacious patient management system (EPMS).

The findings of the research sponsored by the Government of Uganda through the Makerere University research and Innovation Fund(MakRIF) were disseminated during a dissemination seminar held in the College on Friday 24th November 2023, where it was revealed that  Apac the host District greatly benefited from the services that not only led to the increased uptake of internet services but also gained through other socio economic areas.

Makerere University to partner with the Egypt-Japan University of Science and Technology (E-JUST)

Published

on

Makerere University is set to enter into a partnership with Egypt –Japan University of Science and Technology (E-JUST).  The collaboration between the two universities to be formalized with the signing of a memorandum of understanding in the near future will see the two universities working together in a number of respects including staff and student exchanges, joint research and student supervision among others.

The decision comes after a visit to Makerere University by a delegation from the Egypt-Japan University of Science and Technology (E-JUST) on Thursday 23rd November 2023, led by the First Vice President for Education and Academic Affairs Prof. Sameh Nadah.  The team comprised of the Deputy Vice President for Regional and International Affairs Dr. Muntaz Abdeluahaz, Ms. Tomomi Kawazoe the Project Coordinator for JICA E-JUST project and Mr. Racan Yosef, the Section head of International Affairs.
