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.

Hon. Dr. Monica Musenero (3rd L) with the Vice Chancellor, Prof. Barnabas Nawangwe (2nd L), Principal CEDAT-Prof. Henry Alinaitwe (4th L), college leadership, MAPRONANO’s Prof. John Baptist Kirabira (7th L), Kiira Motors’ Mr. Paul Isaac Musasizi (R), Kevoton Motions Engineering Team (in white) and other officials at the launch on 19th August 2021, Freedom Square, Makerere University.

By Betty Kyakuwa

It was a show of innovations geared towards mechanisation of farming processes as the Minister for Science, Technology and Innovations, Dr. Monica Musenero, launched locally made engines today August 19, 2021.

A team of researchers from the African Centre of Excellence for Material science and nanotechnology (MAPRONANO) partnered with artisans from Kevoton Engineering, to design and assemble a diesel engine, the first of its kind in Uganda.

It is a single cylinder 4 stroke engine  with 13 horse power and consumes 1 litre of fuel per hour. The engine is a water-cooled and therefore does not heat up.

The engines are able to run a generator and a water pump to facilitate irrigation on farms. The generator, is single phase and can therefore be used to power home appliances and small workshops.

According to Mr. Mubiru Rogers of Kevoton Engineering, work on the engines started in 2017, but they were not able to make much progress until 2019 when they partnered with MAPRONANO ACE. The centre of excellence was then able provide training and technical advice, designing and student attachments to the project.

The Minister commended the MAPRONANO team, led by Prof. John Baptist Kirabira, for various innovations that the team in churning out, which included a sanitizer made in Makerere, solar panel slasher, and a mini tractor. 

Dr. Musenero challenged researchers to have a mindset change and also change the pedagogy to reposition theory to practical works. “We need to teach the students knowing that they are going to design and develop an engine or a brake system,” Dr. Musenero emphasised.  She encouraged innovators to ensure their products do not stay on the selves, saying the biggest role of science and innovation is economical.  The Minister said, for this reason, PRESIDE which she chairs focused on equipping laboratories in universities so as ensure that scientists receive the facilitation that they require. “Research is like a river which needs an outflow and the Ministry is here to provide that outflow,” she said.

She advised the university to prioritise certain areas of research when it comes to grants instead of awarding small grants to different projects which only end up being a drop in the ocean. Dr. Musenero thanked the President for his continued support and belief in science and technology.

The minister advised that the prototypes be refined so that they are genderised to allow women to be able to operate the generator and water pump.

The Vice Chancellor, Prof. Barnabas Nawangwe, called on the minister to support the introduction of an innovation park in Makerere University, saying the park would be able to spinoff companies. Giving an example of Instabul University, the Vice Chancellor said the university has been able to produce 300 companies over the last one year, saying Makerere University should be supported to do the same.
