Characterization of food wastes from the hotel industry as a potential feedstock for energy production
(Elsevier, 2025) Muchele,Emily Machuma; Osodo,Booker; Omosa, Isaiah; Kombe,Emmanuel Yeri
Food waste contribute to 38% of total Municipal Solid Wastes (MSW) in Kenya and end up in landfills. Due to
high competition in the available space, most cities, including Nairobi, do not have enough space for landfills.
Therefore, there is a need for efficient ways to manage the generated waste. Developed countries have embraced
Waste-to-Energy technologies, minimizing waste generation and converting generated waste into energy and
other resources. Waste characterization is a key element in the energy generation process not only to identify
important parameters but also to guide biomass source segmentation. In this study, food wastes were collected
from 21 hotels within Nairobi City County, in different mixed ratios and subdivided into five samples for
investigation and analysis. The average feedstock characteristics were observed to be moisture content (6.0%, p
< .001, R2 = 90.70 %), total solid (93.7%, p < .001, R2 = 99.97 %), volatile solid (84.3%, p < .001, R2 = 99.80
%), ash content (4.2%, p = .005, R2
= 48.54 %), fixed carbon (5.4%, p < .001, R2 = 88.61%), nitrogen (3.6%, p =
.04, R2 = 36.81 %), carbon to nitrogen ratio C/N (4.0), crude protein (22.4%, p = .004, R2 = 49.36 % ), crude
lipids (12.1%, p < .001, R2 = 89.06 %), total organic carbon (44%, p < . 001, R2 = 94.70%), potassium (0.6%),
sodium (1.2%), calcium (0.2%), and phosphorus (0.4%). The potassium, sodium, calcium and phosphorus p and
R2 values all calculated together were p < .001 and R2
= 72.35%. The results showed a significant difference in
the means of the samples with the majority of the parameters registering a strong positive correlation of above
50%. The analysis revealed that the feedstock under investigation contained well-balanced parameters for
briquette, biogas, syngas and biochar production. Therefore, the findings of this research provide vital knowledge in integrating energy production from food wastes thereby improving the efficiency of food waste

Objectively measured 24-h movement behaviours of child-guardian pairs in low-to-middle income households in Nairobi City County, Kenya

Background: The decreasing prevalence of physical activity (PA) among urban children in Sub-Saharan Africa is a
growing public health concern. More emphasis should focus on examining the influence of parental PA behaviour
on the children’s PA patterns. We explored associations of 24 hour (h) accelerometer-measured movement behaviours of guardian-child pairs in Nairobi City County, Kenya.
Methods: This cross-sectional study assessed 80 pairs consisting of children aged 9–14 years and their guardians in
one area of low and one area of middle socioeconomic status (SES) (Embakasi Sub-County and Lang’ata SubCounty), in Nairobi City County, Kenya. The study used waist worn Tri-axial Actigraph (GT3Xþ and
ActiSleepþ) accelerometers to quantify PA and sedentary time (SED). Association between guardians' and children’s PA was examined using linear regression, adjusting for guardians' educational attainment and household
wealth.
Results: Of the children, 42 (52.5%) and 76 (96.2%) of the guardians were women. Children in low SES areas
spent more time (p < 0.001) in moderate-to-vigorous physical activity compared to children from middle SES
area. The guardians in low SES area were younger and spent more time in light PA (p ¼ 0.036) while their
counterparts had higher daily SED (p ¼ 0.049). Guardian’s SED associated with higher children’s SED (p ¼ 0.033)
even after adjusting for guardians' educational attainment (p ¼ 0.032) and wealth (p ¼ 0.05). There was no
association between guardians' and children’s MVPA.
Conclusion: Considered alongside the extant literature, these results suggest that health promotion strategies
should aim to reduce parental SED time while also planning to increase children’s PA
Supplier Relationship Management and Supply Chain Performance of Flour Milling Companies in Nairobi County, Kenya
(AJEFM, 2025) Chenangat,Mercy; Chege,Wambui
In Kenya, where agriculture forms the backbone of the economy, the production of flour has been steadily increasing, driven by the revenue generated from milling activities converting harvested grains into flour. However, challenges within the flour milling industry have emerged, leading to the closure of subsidiary firms like Mombasa maize and Kitui flour mills due to issues such as insufficient suppliers, competition, and subpar supply chain performance. The inefficiencies extend to the Nairobi context, where outdated supply chain management practices and technological limitations, coupled with weak institutional frameworks, lack of innovation, inadequate infrastructure, and skills shortages, have further hindered the performance of flour milling companies. This study investigates the effects of supplier relationship management onthe supply chain performance of ....
The Influence of Training Reforms on the Performance of Law Enforcement Officers in the Directorate of Criminal Investigations, Kenya
(AJER Publishing Inc., 2025-04) Ong'ale, Margaret Awino; Mwangi, Judy; Sirera, Anne
Police and policing are critical components of any society's criminal justice system. The police maintain law and order, crime prevention and investigations besides ensuring public safety, protection of the basic rights and freedoms of citizens including the right to life. Their duty demands high degrees of competence, proper kitting and support of the government. This study investigated the influence of training reforms on performance of law enforcement in Kenya by the Directorate of Criminal Investigations (DCI), Kenya Police Service. The study was guided by Peelian Principles theory and Legitimacy theory. Mixed-method approach involving descriptive survey with an ethnographic method was used whereby quantitative data was collected using structured questionnaires and the qualitative data obtained using open-ended interview guides and focus group discussions from the members of the civil society. A sample of 384 participants comprising of 230 DCI officers and 154 stakeholders drawn from the civil society and community elders was selected using multistage sampling technique. The data was analyzed using SPSS software version 26.0 using descriptive statistics (frequency distributions, means and standard deviations) and inferential statistics (correlation and regression analysis). The study found that there is a significant moderate positive linear relationship (r=.428, p<0.05) between the training reforms and the performance of the DCI officers. The model predicts 49.4% influence of training reforms on the performance of the DCI (β= .429; Std. Error =.83332; t=6.415; p=0.000). For every unit increase in training reforms is .429 increase on the performance of the DCI officers. This study concluded that training of DCI officers equips them with requisite skills to improve their professionalism in execution of their mandates. The study also concluded that there is need for more and continuous trainings to enable officer tackle the ever-evolving world of crime and improve competencies to adapt to the emerging challenges.
