Research
A diverse range of research initiatives is underway, including material
modeling
for improved energy storage, 3D filament development from recycled
plastics for
medical
applications, livestock farming employing IoT and machine
learning, upcycling
plastic
waste for automobile parts and low-cost building materials, parametric
design,
and additive
manufacturing for wastewater treatment, and a multidisciplinary project
focused on
sustainable
energy and environmental solutions.
Additionally, a
laboratory-based research
team, MAMReT, has
been established to foster research in materials engineering, additive
manufacturing, plastic
waste recycling, and computational modeling, with a mission to facilitate peer
learning and
innovation under the leadership of Dr. James Mutua. These efforts collectively aim
to address
critical energy, healthcare, agriculture, and environmental sustainability
challenges.

1.Computational Material Modelling and Additive Manufacture of Energy Storage and Conversion Devices.
This research was initially funded by Kenya Education Network (2019/2020) and focuses on bridging current energy demand vis-à-vis the prevailing power generation, deployment trends, and potential storage. Computational material modeling and simulation is used in formulating macroscopic models of material property and performance. Holistically, new knowledge in the production of new and emerging energy materials at reduced time and cost has been instituted.
2.Additive manufacture of polymeric materials: 3D filament development and manufacture of medical implants.
This research focuses on recipe development for the generation of 3D filament from recycled plastics. The application of the resultant material in the Additive manufacture of teaching devices, medical implants and sub-structural components. Capacity building and increased specialists in additive manufacturing is envisioned in this work.
Traditional plastic waste handling involves the full life cycle of plastics,
starting from
crude oil extraction and manufacturing into pellets, followed by consumption
and,
eventually, disposal or recycling.
Challenges include spillage,
environmental pollution,
and
harm to ecosystems. Addressing these issues requires sustainable practices like
reducing
consumption, improving recycling, and exploring alternative materials to
mitigate
environmental impact and promote a circular economy.
Therefore a gap exists
to be
exploited to mitigate these problems which is the focus of our proposed plastic
waste
handling methods.
The necessity to develop new and innovative solutions to manage/transform waste into novel materials and alternative energy source is inevitable. This will mop up waste and at the same time improve the livelihoods and economically empower urban communities.
3.Precision livestock farming through integration of Internet of Things and a Machine Learning Algorithm
This research leverages on Machine Learning, to accurately predict diseases
before they
spread within the flock, as well as accurately determine oestrus and calving
windows to
ensure maximum breeding rates.
The application of such technology
will
significantly improve
output in the livestock industry for small and medium farmers, leading to
greater
economic
gain for them, and in extension, the whole country
4.Upcycling plastic waste to novel materials for automobile and marine vessel parts, and low-cost building materials.
This research is geared towards transforming and utilizing plastic waste
materials in
novel
development of automobile and marine vessels parts as well building materials
for
low-cost
housing.
Redesign and performance testing is ongoing with anticipated
piloting.
5.Parametric design and additive manufacture of plastic waste biofilter for sustainable waste water treatment.
This research focused on the development of a bioreactor system for treatment of urban sewage for enhanced agricultural production. This entailed characterization of the effluent from wastewater treatment plants, development of a bioreactor system utilizing waste plastic materials and use the parametrically optimized biofilters to treat the waste water. Piloting of the system in a kitchen garden scale irrigation project will be done with potential evaluation of its sustainability in upscaling of the processed water for large scale agricultural use
6.Integrated Research and Innovations in Additive Manufacturing for Sustainable Energy and environmental solutions
This is a 3-year ongoing multidisciplinary project funded project by Africa-ai-Japan Projects (Phase II) 2022 - 2024. The goal of this study is to design and develop novel materials, process through additive manufacturing and thermo-mechanically recycle waste plastics for sustainable energy solutions and provide a clean and healthy environment
7. Establishment of Materials and Additive Manufacturing Research Team (MAMReT).
The researcher has established a research team named MAMReT to
effect
research in the areas
of Materials Engineering, Additive Manufacturing, Recycling of plastic waste,
and
Computational modelling of energy materials. The goal is to establish a
laboratory based
research system where peer learning will be cultivated from the lowest level
(BSc to
PhD)
spearheaded by the thematic leader (Dr. James Mutua).
The ultimate goal is to set-up a Centre for Additive
Manufacturing
(CeAM) at JKUAT.
