(2022)Keratin is one of the most abundant proteins, which is derived from wool, feathers, nails, hair, and other sources. Chicken feathers are a well-known keratin waste by-product, produced in large quantities by poultry ... -
Beneficiation of pulp and paper mill sludge: production of cellulose nanofibrils (CNFs).
(2022)Depletion of landfill space, the cost of waste disposal, and environmental concerns are pushing Pulp and Paper Mills (PPMs) to make changes and improvements in the way waste is handled. Pulp and paper mill sludge (PPMS) ... -
Techno-economic assessment of algae conversion to biofuels.
(2023)One of the most promising biomasses for the production of biofuels is microalgae. This is because microalgae have a high growth rate and a highiCO2icapture ability when compared to other biomasses. Furthermore, biofuels ... -
Decentralised sanitation to fill the gap in urban wastewater treatment within the eThekwini Municipality: a focus on tertiary treatment in vertical down-flow constructed wetlands.
(2022)South Africa’s bulk sanitation infrastructure is failing, and there is an urgent need to look at other appropriate sanitation solutions. Moreover, there is no data on the proportion of population with access to safely ... -
A model of calcium and phosphorus growth in broilers.
(2022)A model is a simplified representation of a system. It can be used to organise knowledge and to develop theory in an academic setting, but also for practical applications. This research sought to incorporate as much as ... -
Towards developing a pluralistic agricultural extension system: the case of Vhembe district of Limpopo province, South Africa.
(2022)Agricultural extension is a crucial component of agricultural development, food security improvement and rural livelihood enhancement. However, many farmers are constrained by extension systems that are difficult to ... -
Co₂ solubility measurements and modelling in amine-NMP solvent blends.
(2022)In this study, solvent blends of monoethanolamine (MEA) or 2-(2-aminoethoxy)ethanol (DGA) with N-methyl-2-pyrrolidone (NMP) or water (H2O) were selected for investigations of carbon dioxide(CO2) solubility due to the high ... -
Impact of crop productivity and market participation on rural households’ food and nutrition security status: the case of Mpumalanga and Limpopo provinces, South Africa.
The agricultural sector has proven to be the backbone of improving rural households’ food security and livelihoods in developing countries. However, the sector faces numerous challenges, such as insufficient access to ... -
Biocontrol agents in combination with moringa oleifera leaf extract for integrated control of botrytis cinerea of tomato.
(2022)Tomatoes and tomato-based foods provide essential nutrients beneficial to human health. Despite these benefits from tomatoes, postharvest losses result in unprofitable tomato production in some parts of the world. During ... -

(2022)The purpose of the study was to understand the effect of nutritional knowledge on physical activity, dietary intake, and anthropometric measurements in high-school learners. The study further underscored the value of ... -
Dormancy breaking methods and priming techniques to improve seed germination in gynandropsis gynandra (L.) briq syn cleome gynandra L. (Cleomaceae).
(2022)Gynandropsis gynandra, commonly known as spider plant, is a leafy vegetable that belongs to the Cleomaeae family. Spider plant is used for its medicinal properties, but also as a nutritional supplement, and an animal ... -
Evaluating seed quality and performance of low and high phytic acid maize (Zea mays L.) under varying phosphorus rates and water regimes in dryland conditions.
Maize (Zea mays) being the staple crop for many communities in Sub-Saharan Africa and also used for animal feeding, a considerable effort has been made to improve quality and yield. In recent times plant breeders have ... -
Assessing variability in yield performance and nutritional quality of citron watermelon (citrullus lanatus var. citroides (L.H. Bailey) mansf. ex greb.) genotypes under drought conditions.
Research is needed to investigate the potential of Neglected Underutilized Crop Species (NUCS) such as citron watermelon, to increase crop diversity and mitigate the effects of prolonged drought because of climate change. ... -
Prediction of milk yield using visual images of cows through deep learning.
The broad objective of the study was to determine, through deep learning, the predictability of milk yield from a cow's image data. The data size of 1238 image pairs (the side-view images and the rear-view images) from ... -
The impact of quarrying activities and communal perceptions towards the environmental and animal welfare in the Ashburton community located in KZN Province, South Africa.
(2022)The aim of this research was to evaluate the animal distribution, water quality, and how the communal residents perceive the quarry existence in the surrounding community. A qualitative survey in a form of semi-structured ... -
Response of growing rabbits in growth performance and carcass composition to balanced dietary protein.
(2023)The broad objective of the study was to measure growth performance and carcass composition of growing rabbits as influenced by the dietary protein levels. A 56-day feeding trial was conducted to measure the response of ... -
An ex ante assessment of the farm-level impacts of further developing sugarcane biorefineries in the South African context.
(2022)The gross sugar production in South Africa (SA) tends to exceed the quantity demanded locally. Surplus sugar is sold in the global market at prices that are typically below the cost of sugar production in SA. This amongst ... -
