Ilhaam Patel

Ilhaam has an undergraduate degree and MSc in Chemical Engineering from UCT – the latter including a comparative Life Cycle Assessment (LCA) of bioenergy generation options from selected waste streams in South Africa. She has been involved in research and analysis projects relating to the mining, minerals, energy, agriculture, dairy sectors, consumer products and retail, with a particular focus on product LCAs and environmental product declarations. Her work in LCA involves on-site and desktop-based data collection, data processing and analysis, and the development and assessment of LCA models and impact assessment methods. Ilhaam has a keen interest in the development of regionalized impact assessment methods specific to the unique South African context.

Further to her consulting work, Ilhaam also heads up the sales and support of SimaPro at The Green House, which includes the provision of LCA and SimaPro training. Ilhaam is also currently providing support as a mentor in the Environmental Leaders Programme (ELP), a Graduate Development Programme run by WWF South Africa.

Alexandra Logan

Alexandra holds undergraduate and Honours degrees in Earth Science from Stellenbosch University and an MSc in Sustainable Development and Climate Change from UCT. Alexandra’s MSc thesis focused on the sustainability of luxury safari lodges. She is currently involved in projects and research relating to climate change mitigation in South Africa, including the quantitative modelling of emissions projections across the economy. She has also been involved in projects relating to energy efficiency, agriculture, low-emissions development and co-benefits, minerals beneficiation and employment vulnerability due to climate change.

Matthew Burke

Matthew has an undergraduate and MSc in Chemical Engineering. His masters research was in the bioengineering field and included the design of algal reactors to improve growth while ensuring low energy usage. The possibility of carbon capture and utilisation within these systems was considered. Since completing his studies Matthew has worked as a research assistant in the Centre for Bioprocess Engineering Research (CeBER) at UCT with a specific focus on the production of bioenergy through anaerobic digestion and waste water remediation. Since joining The Green House he has been involved in projects relating to greenhouse gas inventory development and reporting, carbon footprinting, landscape approach mitigation planning and municipal training for carbon reporting.


Samantha Galvin

Samantha is our office manager who ensures the smooth running of the TGH office. Samantha comes from an event coordination and accounting background.


Bellinda Monyela

Bellinda holds an undergraduate degree in Ocean & Atmospheric Sciences and Environmental & Geographical Sciences and Honors in Oceanography from the University of Cape Town.

She completed her Master’s coursework in Climate Change and Sustainable Development, facilitated by the African Climate and Development Initiative (ACDI) and she is in the process of completing her dissertation under the Oceanography Department. Her M.Sc. involves the monitoring of droughts during austral summer in South Africa during the 21st century. Bellinda is fascinated by ocean and atmospheric dynamics and how the interaction between these Earth systems affects the society. She is also interested in community work, volunteering and youth development. Hence, she is facilitating a project at Gugulethu under the Applied Centre for Earth Systems Sciences (ACCESS) to mentor and prepare the learners for post matric opportunities, to network with other learners across the world and also to help them understand the season cycle and climate of South Africa.

She joins TGH under the WWF Environmental Leaders Programme.
