Adefemia.jpg

Adefemi A. Alade

Femi, as he is popularly called, hails from Ekiti State in Southwest Nigeria and is studying for a PhD in Wood Product Science. His research is focusing on formulation of effective natural product-based preservative from bio-wastes for wood protection. This is aimed at reducing health and environmental impacts associated with hazardous chemical wood preservatives. He is seeking to improve, through synergy and modification, the wood preserving potentials of lignin and extract from citrus fruit peel which are industrially generated as unwanted materials in the pulping process of paper making and fruit juice processing respectively.

Crafford.png

Philip Crafford

Philip is from Worcester in Western Cape.  In the last decade Green Building has become synonymous with development. Buildings are responsible for about 33% of global anthropogenic carbon dioxide emissions (Allwood et al. 2010), as construction and use of buildings involve high energy consumption/emissions, environmental pollution, and other environmental resource uses (UNEP 2009). There is no doubt the way future towns and cities are developed will be a key to moving closer to environmental sustainability on earth. There are various ways to evaluate or measure the environmental sustainability of buildings. His work research focus on 'Measuring environmental sustainability of buildings in South Africa with a focus on timber building systems'

Werner's PhD project focuses on improved understanding of growth dynamics of the Zambezian-Baikiaea woodlands, with particular focus on Burkea africana and Pterocarpus angolensis. The aim is to study growth increments and regeneration responses of Zambezian-Baikiaea woodlands to silvicultural interventions, mainly thinning, through field experiments established in Namibia at Kanovlei and Hamoye State Forests and Okongo Community Forest. The project strives to understand how forest stand growth and regeneration in the Zambezian-Baikiaea woodlands vary by stand densities along thinning intensity gradients.

Olayiwola Hamed Olafiku

Olayiwola Hamed Olafiku is from the largest city in West Africa, Ibadan, Nigeria. He had his B.Sc and M.Sc degrees in Wood Products Engineering from the premier university in Nigeria, University of Ibadan. His quest for finding alternative green materials to the conventional building materials led him to the Ph.D degree programme of the prestigious Stellenbosch University in Wood Product Science. The use of the conventional construction materials are highly energy intensive and processes involved in their manufacture lead to emission of greenhouse gases (GHGs) that add to the global carbon footprint. His research focuses on the development of low cost building materials by incorporating wood fibres (from alien invasive wood species) and agricultural crop residues into geopolymeric matrices developed from various industrial wastes.

Nkosinamandla Artwel Sizwe Gonya 

Nkosinamandla is from Kwa-Zulu Natal (Estcourt).  He obtained a BSc degree in Wood and Wood Products Science in 2016 at Stellenbosch University, currently doing MSc in the same field.

Topic of Research: Profiling the shrinkage and collapse of Eucalptus grandis across the tree trunk and height-wise, and their relationship to the basic tree and wood properties.

We hope to solve the shrinkage and collapse (dimensional instability) experienced in Eucalyptus grandis after drying by grouping boards from parts with more similar properties in the tree stem, hence being able to use this fast growing wood for structural purposes.

Rugare.jpg

Custon Rugare

Custon is from Buhera District in Zimbabwe and currently doing MSc in Forest Engineering.

The number of mechanised CTL harvesting operations are rapidly increasing in South Africa.  Being a relatively new phenomena and a significant departure from motor-manual operations of the past it is important to understand the contribution of machine costs and productivity to the overall success of mechanisation initiatives.  Ratio's such as availability and utilisation are largely unknown or a best poorly understood.  The same applies to repair and maintenance costs along with the costs of running gear.  This research uses long term operational records and machine computer systems to provide base information for the calculation of benchmark information which machine owners can use to potentially validate their data being use in day to day operations.

Vhuhwavho.jpg

Vhuhwavho Tshavhungwe

Vhuhwavho Tshavhungwe was born and raised in Venda in the Limpopo province. She first learnt about forestry and wood science as something people study when she applied to do a learnership with Komatiland forests for her gap year in 2012. From that moment onwards it made sense to her why there are all those pine and eucalyptus trees planted along the road where she come from. She came to Stellenbosch University in 2013.  She loves studying wood science because the degree is structured in such a way that it incorporates both wood science and industrial engineering concepts. 

She is currently on her 1st year of masters and will be investigating the wood property variation of sawn timber, particularly those properties used in the grading of timber.  Datasets with the relevant information will be collected from sawmill(s). Statistical quality control techniques will be implemented in the project.

Benjamin.jpg

Benjamin van Heerden

His fascination with forestry started when Benjamin was still a little boy living in Hazyview, where the surrounding plantations filled him with wonder. Although he moved around a lot as a child the memory of those plantations remained with him and eventually led him to study forestry. "In all honesty, I knew very little about the industry when I arrived at Stellenbosch as a first year forestry student in 2013, but the more I learned, the more my passion for forestry grew." He finished his undergraduate studies in 2016.  His postgraduate study focuses on developing a model for carbon allocation in the roots of coppiced Eucalypts which will give insight into the carbon sequestration potential of these trees.

Philip van Niekerk

Philip is a South African student from George in the Southern Cape and presently in the first year of doing his MSc in growth and yield science. He finished his undergraduate studies in Wood Product Science at Stellenbosch in 2015. He decided to do his postgraduate studies in forestry to bridge the gap between raw material and product by understanding the entire wood supply chain. His project focuses on creating allometric equations/models to predict above ground biomass of Eucalyptus grandis x nitens. Furthermore, he will look at the nutrient properties and the carbon sequestration potential of the Eucalyptus specie.

RolandWenhold.jpg 

Roland Wenhold

Roland is currently busy with his Msc degree in Forest Engineering at the University of Stellenbosch. He was born in Rustenburg in the North West province and grew up on a farm in Swartruggens. As a farm boy he always loved nature and agriculture. In 2012 he started his studies at Stellenbosch University in BSc Forestry. He is an outdoor person with an out-going personality and have a natural aptitude for nature, trees and the environment. He is a self-confident communicator, with a strong ability to do several tasks at the same time.

The main objective of his study is to determine machine operator learning curves on newly installed harvesting operations from inception to maturity. Under South African conditions the learning curve for modern harvester operators are unknown and this opportunity to do so makes this study significant. By integrating operator data, machine data and productivity information, will enable a holistic view of the life cycle of a greenfields (new and first time) mechanisation projects in the South African forestry industry. This study will also be applicable for companies and contractors interested in using modern purpose built harvesters.
