HIGHLIGHTS AND ACHIEVEMENTS

NATURAL ENVIRONMENTClimate change and heat stress vulnerability in Johannesburg

Dr Rebecca Garland, Dr Caradee Wright, CSIR Shalin Bidassey-Manilal, Prof. Koos Engelbrecht, TUT

BackgroundAfrica is experiencing an increase in temperature due to a change in climate. The interior regions of Southern Africa are expected to have increases in temperature of 4 – 6˚C (under a low mitigation scenario) by the end of this century. The region is also expected to experience a higher rate of increase in temperature than the global average.

Urban environments are more vulnerable to high temperatures, due to the urban heat island effect and poor air quality. Higher temperature can affect human health through heat stress and heat stroke, as well as lead to increased mortality.

The thermal performance of buildings contributes to people’s exposure to high temperatures.

In Johannesburg, many school buildings rely on natural ventilation for the thermal regulation of the indoor temperature. At high temperatures, thermal comfort may be reduced, potentially affecting the performance and health of learners and teachers.

ResponseThis study investigates the effect of heat on learning and the health of learners in Johannesburg. Primary data was collected at eight schools in the

city during the summer. These schools were located in communities with varying socio-economic status.

The first of two questionnaires, which was for the learners, focused on heat-related symptoms experienced at school. For five days, every hour, learners recorded any heat-related symptoms they felt. Lascar data loggers were used to measure the temperature and relative humidity inside the classroom. The second questionnaire was for school principals and it focused on school and classroom infrastructure, as well as coping mechanisms during hot weather conditions.

ProgressClassroom temperatures in all the schools sampled in February 2016 were greater than 25°C. During 45% of the days, indoor temperatures exceeded 30°C. The highest temperature recorded was 47.5°C.

Six schools were built of brick, one was a converted metal shipping container and another one was built from prefabricated asbestos with a metal roof. All schools relied solely on natural ventilation. The principals reported that teachers left the windows open during lessons. Higher temperatures were recorded in classrooms constructed with asbestos and corrugated iron roofs, as well as converted shipping containers as opposed to those built with bricks.

Most of the students who participated in the study recorded at least one heat-related symptom. A high proportion of the students had low levels of concentration during at least one hour each day in the summer. There was a statistically significant correlation between indoor temperatures greater than 32°C and the self-reported fatigue of students.

BIOSCIENCES Evaluation of promoters for enhanced recombinant protein expression in Bacillus halodurans

Nolwandle Nxumalo, Dr Michael Crampton, CSIR

Christian Reitz, Prof. Peter Neubauer, Technical University of Berlin, Germany

Prof. Renate Roux-van der Merwe, TUT

Background

The increasing need for new therapeutic production approaches, as well as the potential of peptides to be active pharmaceutical ingredients for effective drug formulation, is contributing to the

rapid development of the therapeutic market. Bacterial expression systems for heterologous protein production are attractive because they can grow rapidly at high density on inexpensive substrates and often have well-characterised genetics. High-level production of recombinant protein is often achieved by cloning the gene of interest downstream of a well-characterised and regulated promoter.

ResponseA proprietary expression system was developed at the CSIR exploiting the ability of B. halodurans Alk36 to produce flagellin sub-units, the main building blocks of flagella, at high titres. B. halodurans was genetically modified through gene targeted inactivation of key proteases to improve the secretion of therapeutic peptides linked to flagellin sub-units. However, biomass could not be linked to product yield. Promoter regulation was thought to be the primary limiting factor of this expression system. Therefore, a directed evolutionary approach to enhance expression through the deregulation of the saps promoter was investigated. In conjunction with this approach, promoters used routinely for recombinant protein expression in B. subtilis will also be evaluated.

ProgressThe promoter library was initially evaluated in E.coli since transformation into B. halodurans is inefficient for promoter library screening. Approximately 1 000 colonies were visually screened on an agar plate under Ultraviolet light. One of these clones was also visualised using florescence microscopy and demonstrated improved Green Fluorescent Protein (GFP) expression when compared to the non-mutated saps promoter. Based on the plate screen, a subset of the library was screened on the Hamilton MicroLab Star robot. Selected clones were sequenced and mutations detected. Those promoters with mutations within the -10, -35 and Shine Dalgano regions were validated for GFP expression in E.coli. These selected promoters were then transferred into B. halodurans BhFDL05S. Enhanced GFP expressions observed after 48

hours of growth, in selected culture media, demonstrated deregulation of the saps promoter in B.halodurans. The promoters showing enhanced GFP expression will now be evaluated for therapeutic peptide production.

The expression levels of GFP demonstrated an improvement in recombinant protein titres and the deregulation of the saps promoter, which was achieved through random mutations. The selected promoter library is being evaluated for the improved production of recombinant therapeutic peptides. The technology will be implemented as an expression platform within the CSIR for recombinant protein production.

BIOSCIENCES Isolation and identification of compounds from South African plant species with anti-cancer properties

Dr Gerda Fouché, Rudzani Nthambeleni, Dr Paul Steenkamp, Dr Xolani Peter, CSIR

Prof. Comfort Nkambule, Dr Jacqueline Tembu, Dr Tozama Ogunleye, TUT

Background

Natural products from plants have been used for centuries to prevent or cure diseases.

They are important in cancer chemotherapy, because they provide new drugs and leads for synthetic modification, as well as produce taxol, which is a substance that provides a better molecular mechanism germane to cancer. Taxol is a proven natural compound isolated from Taxus brevifolia, which is used to treat breast cancer. Exploring the rich South African biodiversity for new and improved anti-cancer hit leads and potential agents is the main objective of the collaboration.

Cancer is the second leading cause of death worldwide. Globally, more than six million people die of the disease every year, while over 22 million people are living with cancer. Cancer is caused by abnormal cells that grow rapidly and invade one part of the body before spreading to other organs. The Cancer Association of South Africa estimates that over 100 000 people are diagnosed with cancer in South Africa each year.

ResponseTUT and the CSIR are involved in postgraduate research in natural product chemistry and synthetic chemistry. The main objective of collaboration in

these areas is to isolate, synthesise and identify compounds from the plant species of the genera Leonitus, Dicoma and Suregada with potential anti-cancer properties. This will be achieved by:

• Extracting and isolating natural compounds from the aerial parts of Suregada, Leonotis and Dicoma genera through bioassay-guided fractionation methods and sequential extraction methods,

• Structural elucidation of pure isolated compounds. Spectroscopic data will be used for the characterisation of the isolated compounds,

• Synthetically elaborating two generic scaffolds by conjugation with biologically active subgroups, 1,2,3-triazoles and tetrahydrofurans, and

• Screening the isolated and synthetic compounds for efficacy in vitro and toxicity against cancer cell lines.

This collaboration enables students to use the complementary infrastructure at both institutions.

INFORMATION AND COMMUNICATION TECHNOLOGYSmart water management system

Dr Adnan Abu-Mahfouz, Dr Philip Page, Muhammad Osman, CSIR Prof. Yskandar Hamam, Prof. Anish Kurien, Prof. Karim Djouani, Dr Bolanle Tolulope Abe, TUT and FSATI Prof. Gerhard Hancke, University of Pretoria Dr Olivier Piller, The National Research Institute of Science and Technology for Environment and Agriculture, France Prof. Ezio Todini, University of Bologna, Italy Dr Gerhard Hancke, Chinese University of Hong Kong, China

Background

Because South Africa has limited water resources, there is a great need for the efficient and effective management of the water distribution network in the country. The growing water demand,

high water losses and non-revenue water threaten water security, as well as the financial viability of municipal water provision. Recent failures of key water infrastructure have raised concern that the situation could deteriorate further.

The Department of Water and Sanitation estimates that non-revenue water and water losses in South Africa amount to 36.8% of total supply (1,580 million m3 per annum), whose annual financial value is more than R7 billion.

It is difficult to determine and locate inefficiencies in the water distribution network and make the relevant adjustments to the network parameters based on the collected data and predictions of future state (all in near real-time). Furthermore, the sensory and automation overlay required for the network can cause technical problems that also need to be solved before water utilities can implement these techniques.

ResponseThe current design and operation of most water distribution networks rely on steady-state hydraulic models that are unreliable and inefficient.

The CSIR, TUT, French South African Institute of Technology (FSATI) and the University of Pretoria are developing a smart water management system to address potable water loss. The system is based on a real-time dynamic hydraulic model control system connected to near real-time sensing and actuation capability on the water distribution network. The smart water management system will provide a strong scientific basis for network planning and management and identify operational problems.

ProgressNovel algorithms for pressure and speed pump control have been developed. WaterGrid-Sense, which is a general monitoring and control device, has also been developed and licensed to a South African company. Several of these devices have been deployed to create a smart CSIR water campus.

The system is likely to be piloted in the City of Tshwane or other municipalities in collaboration with two companies (Comsol and Internet Solutions).

LASER RESEARCHPulse laser machining of silicon nitride ceramics

Dr Lerato Tshabalala, Dr Sisa Pityana, CSIR

Prof. Patricia Popoola, TUT

Dr Lother Schafer, Fraunhofer-Gesellschaft, Germany

Background

Ceramics are used widely in fields such as automobile manufacturing, tribology, as well as structural and other specialised areas. Silicon nitride structural ceramics have potential application in high strength

and high-temperature tooling applications. They are however brittle in nature and in most instances polycrystalline diamond thin films gets deposited on their surfaces to extend operational tool life. However, the challenges for adaptation have been low film adhesion of the diamond coatings, which is mainly attributed to the brittle nature of the silicon nitride as a substrate.

During mechanical pre-treatments of the ceramic, the intensity of the damage on the sub-surface is reduced, with some micro-cracks, dislocations, slip and interfacial stresses remaining. To improve the endurance time of the polycrystalline diamond films deposited on silicon nitride substrates, a novel surface treatment approaches had to be adopted.

ResponseThe research investigated laser surface machining of the ceramic surface to improve adhesion of deposited coatings on the tooling inserts. The parametric investigation process was conducted to provide evidence of laser-matter interaction that results in the improvement of coating adhesion.

Pulsed laser micro-machining technology was used as a surface pretreatment method on structural ceramics that are difficult to machine. This is a contactless process for high-precision machining that can simultaneously transform surface characteristics. The laser was used to reduce defects such as micro-cracks on the ceramic surfaces and provide machined surface quality conducive for the deposition process. Three different lasers, namely high frequency nanosecond Nd: YAG laser, low frequency nanosecond (neodymium-doped yttrium aluminium garnet) Nd: YAG laser and femtosecond titanium-doped sapphire laser (Ti-Sapphire laser) were investigated.

ProgressCommercial ceramic samples were used to evaluate the variance in laser treatment response on different types of silicon nitride ceramics. The results showed that laser treatment can enhance material roughness and remove

the damaged material zone from grinding operations in production of the sintered tools, thereby improving diamond adhesion.

It was also evident that the various materials followed a similar trend of reduced thermal conductivity at elevated temperatures with insignificant differences between all samples. This has led to the modelling of heat penetration in different materials with different absorption coefficients to support the variations resulting from the differences in material thermophysical properties.

HUMAN CAPITAL DEVELOPMENT OVERVIEW

Dr Hamilton Mphidi, TUT

Pinda Sifunda, CSIR

One of the challenges facing South Africa is to build highly qualified people, through sustained investment in education and training, who can compete effectively in the global economy. This is often constrained

by limited funding.

To address this challenge, TUT and the CSIR have established a joint scholarship programme for students enrolled for Honours, Master’s and Doctoral studies in areas identified in the CSIR/TUT. From 2013 to 2016, 18 students [5 Bachelors, 11 Masters and 2 Doctoral] studied in areas such as engineering, information technology, polymer technology and architecture. In addition, the CSIR studentship programme has funded 28 students to study at TUT. Through these, 14 students graduated between 2013 and 2016.

The collaboration enables TUT students to access CSIR state-of-art-facilities such as the National Centre for Nano-structured Materials and the Photonics Initiative of South Africa programme at the CSIR National Laser Centre. TUT and CSIR researchers co-supervised students. Honorary appointments were awarded to five CSIR researchers by TUT from 2013 to 2016. Forty-six CSIR researchers lectured and supervised students at TUT.

TUT is becoming an important institution for research and innovation because of its rated researchers, South African Research Chairs Initiative (SARChI) and the Centre of Excellence.

The University has 50 National Research Foundation-rated (NRF) researchers

in diverse areas of research including pollution studies, materials science, information technology, water treatment and laser research.

Research capacity at TUT has also been enhanced through the South African Research Chairs Initiative. From 2013 to 2016, the NRF awarded seven Research Chairs to TUT. TUT also co-hosts two centres of excellence in scientometrics and science, technology and innovation policy and food security.

This capacity contributes to collaboration between the CSIR and TUT and improves the technological and innovation capability of South Africa.

TESTIMONIALS

Rohan van Eeden is studying architecture with a focus on the design of a biophilic wastewater treatment facility in Diepsloot, Johannesburg. The project is a decentralised and integrated solution to wastewater management. It serves as an alternative to the energy intensive and over-capacitated infrastructure that currently exists.

The architectural response is the design of a hybrid wastewater treatment facility that provides sewerage infrastructure to the local community, an integrated thermal energy conversion plant, as well as a hydrological education and research centre, which will inform and educate the users about hydrological systems. The design accomplishes this through the multi-sensory exploration of space: A series of spaces with linking walkways that address the objective of enhancing architectural experiences. By providing a public platform, residents and visitors are provided with an educational journey where they can experience the natural and built environments, thereby leading to a better understanding of the area’s unique ecology.

This response could create awareness by involving the community in the treatment of water and the conservation of natural environments – the most valuable resource.

Maleshoane Anastacia Sepeame studied for an MTech (Business Information Systems) from 2013 to 2014. Her research focused on the implementation of mobile government in a developing country. Mobile government (m-Gov) is the use of mobile technologies to deliver public services. Traditional communication often fails to provide satisfactory services to the public. The use of mobile technologies presents an opportunity to reach the broader public in developing countries. The purpose of this study was to develop an appropriate framework for the successful implementation of m-Gov and to suggest guidelines to enhance service delivery in developing countries through m-Gov. This study applied a triangulation of the technology acceptance model and m-Gov maturity models as a theoretical framework for the evaluation. The results of the study will provide guidelines for the successful implementation of m-Gov in a developing country.

Crisantia Nyaka is studying towards an MTech in Industrial Engineering. Her research focuses on the development of a supply chain blueprint for the reconfigurable bending press machine. Highly competitive press machine imports from Europe and Asia have reduced the global competitiveness of the South African press machine manufacturing industry. For the local industry to regain its competitiveness, it needs to invest in the development of technologies such as the reconfigurable bending press machine.

Competition in the press machine manufacturing industry is currently determined by the supply chain network strength. The research will contribute to the development of a viable supply chain blueprint for the reconfigurable bending press machine for its future launch into the industry.

A supply chain blueprint will strengthen South Africa’s manufacturing sector and contribute to economic growth.

Tiisetso Malepe is studying for an MTech in Metallurgy and Material Engineering with focus on environmental friendly fuels for automobiles. The objective of his Master’s study is to replace fossil-based fuels that are used currently in automobiles with more environmentally-friendly ones, such as hydrogen. These fuels should be replaced because during combustion they produce greenhouse gases that damage the ozone layer and contribute to climate change. Hydrogen is environmentally friendly and a potential candidate for replacing traditional fuels.

The most viable method for storing hydrogen for use in vehicles is in highly pressured type IV vessels in its compressed form. Type IV tanks are light, strong and have a long life span. These tanks are made of polymer liners, reinforced fibres and aluminium necks. They can effectively resist corrosion and fatigue caused by repeated injections of gas.

This will be done by developing aluminium necks and high-density polyethylene of type IV compressed hydrogen storage using cold spraying techniques. Developing an adhesive and strong gas sealing aluminium coating on high density polyethylene will ensure that hydrogen is stored as the new fuel for automobile and Hydrogen gas fuelled automobiles minimises the emission of greenhouse gases.

The joint scholarship programme has supported the training of postgraduate students working on joint projects. TUT, as well as other South African universities, has played an important role in training CSIR staff to acquire higher qualifications.

SUPERVISED RESEARCH

Thermal reduction of calcium sulphate

Solly Motaung, CSIR

Supervisors: Prof. Christian Wolkerdorfer, Prof. Andrei Kolesnikov, TUT Dr John Zvimba, WRC

Background

Water scarcity in South Africa is becoming widely recognised. This problem is increased by the erratic rainfall and pollution of available water resources. Without adequate water, it is impossible

to grow businesses and sustain livelihoods. Therefore, there is a need to investigate other possible sources to increase the amount of useable water. One of the potential sources is acid mine drainage (AMD), which also has high metal content and mineralisation and can result in the permanent damage of ecosystems. In some instances, it contains radionuclides.

The process of purifying AMD involves several stages. Gypsum is precipitated during the treatment of mine water, using limestone or lime, to produce usable water. If not treated or recycled, the precipitated gypsum could become a source of pollution due to the leaching of pollutants. Valuable products such as calcium carbonate can be extracted from gypsum to offset the treatment costs.

The thermal reduction stage is one of the most costly stages during gypsum sludge treatment because it is performed at high temperatures and uses expensive reducing agents. Valuable products such as elemental sulphur can be extracted during this stage to offset the treatment costs.

ResponseThe collaborative research between the CSIR and TUT focused on the thermal reduction of calcium sulphate using a tube furnace to produce calcium sulphide. This calcium sulphide is used to produce elemental sulphur and calcium carbonate.

Calcium sulphate was thermally reduced in the presence of three reducing agents, namely, coal, charcoal and petroleum coke. The efficiency of these three reducing agents was studied for the thermal reduction of calcium sulphate. The results showed that coal was a better reducing agent than the other two.

Calcium sulphate was also mixed with coal and either starch or microcrystalline cellulose and pelletised before subjecting the mixture to thermal reduction

studies. The two additives did not hinder the thermal reduction efficiency. This implies that they can be used if there is a need to pelletise the gypsum and coal before the thermal reduction reaction.

Calcium sulphate sludge precipitated on full scale when AMD was neutralised with lime and limestone was mixed with coal and pelletised in the presence of a starch. The pellets, which were formed using a disc pelletiser, were subjected to high temperatures to reduce calcium sulphate to calcium sulphide. Kinetics of the thermal reduction of pelletised calcium sulphate were measured.

ProgressThe paper that was submitted to the Water Institute of Southern Africa conference won the Southern African Industrial Water Pressley Hughes award.

Development of environmentally-friendly polymeric materials based on Polylactide and Poly [(butylene succinate)-co-adipate] blends

Vincent Ojijo, CSIR

Supervisors: Prof. Suprakas Sinha Ray, CSIR Prof. Rotimi Sadiku, TUT

Background

Non-biodegradable polymer products, such as packaging films, create environmental problems when disposed. To partly address this issue, alternative polymers, mostly derived from renewable

bio-sources, such as, corn, have been developed. This category of polymers includes polylactide (PLA), which is derived from lactic acid. The lactic acid may be produced through fermentation of organic products, such as beet, corn or agricultural wastes making it environmentally benign. However, PLA is usually brittle and has a slow crystallization rate. It is also thermally unstable and susceptible to loss in molecular weight during melt processing. This makes it unsuitable for use as packaging material where flexibility is a major requirement. The objective of the project was to develop PLA-based hybrid materials with better barrier properties, thermal stability and impact resilience.

ResponseThe properties of PLA, were modified to enhance its ability to replace some of the commonly-used non-biodegradable polymers, such as polyethylene. PLA was blended with more flexible and yet biodegradable polymers, such as, polybutylene succinate-co-adipate (PBSA). The morphology-property relationships of these blends were established. It was noted that blends are immiscible and result in a phase-separated morphology, which leads to deterioration in properties. To address this, nano-clays and a reactive compatibilization process were used to control the phase morphology, and to confer useful properties. The most significant contribution of the research was the successful modification, in one step, of diverse properties of PLA, e.g. ductility, thermal stability, crystallizability and barrier properties. Unlike the neat PLA, the developed PLA/PBSA-based hybrid materials can easily be made into flexible films through industrial scale film extrusion processes and may be used as packaging material for certain groups of products.

Future workFuture work includes functionalization of the nanoclays with chain extenders for the application in, compatibilization of immiscible polymer blends, and as a unique chain extension agent during the recycle of polyesters such as polyethylene terephthalate. Furthermore, in order to address the relatively

high water vapour transmission rates in the developed PLA-based hybrid composites, it is proposed that hybrid multilayer films be developed, with bio-sourced polyethylene in the outer layer and the PLA-based composites in the middle layer, and forming the bulk of the film.

Laser-based characterisation of aggregate shape properties affecting performance of asphalt mixes

Madikole Mary Mabuse, CSIR

Supervisors: Dr Joseph Anochie-Boateng, CSIR

Prof. Julius Ndambuki, TUT

Background

There are concerns with the standard test methods of quantifying the shape properties (i.e. angularity, surface roughness, flatness, elongation and sphericity) of aggregates used for road pavement

construction. These test methods are time and labour intensive and have several limitations, including lack of accuracy and repeatability of test results.

ResponseResearchers and practitioners have suggested that advanced and automated approaches, such as imaging and laser scanning techniques, would better quantify the shape and surface properties of aggregates. For instance, the CSIR found that a portable three-dimensional (3D) laser scanning system can accurately quantify the shape properties of aggregate particles. The 3D laser scanning system was used to characterise aggregate shape properties such as form, angularity and surface texture, which affect the performance of asphalt mixes. The shape properties of aggregates obtained from the laser scanning method were correlated with the performance of three hot-mix asphalt mixes used for road construction in South Africa.

The spherical harmonic analysis from the 3D laser scanning device better characterises aggregate surface texture, angularity and form properties.

Two permanent deformation test methods proved that there is an effect of shape properties on the performance of asphalt mixes, but give contradictory results.

According to the triaxial loading test method, better resistance to permanent deformation is provided by aggregates with low surface texture and angularity, while the Hamburg wheel tracking test indicated that it results from aggregate particles with high surface texture and angularity.

This is understandable as the modes of testing are different. These results have shown that aggregate shape properties play a major role on the performance of asphalt mixes.

Enabling Internet connectivity through television whitespaces in rural areas

Elesa Ntuli, TUT

Supervisors: Dr Fisseha Mekuria, CSIR

Prof. Seleman Medson Ngwira, Dr Tranos Zuva, TUT

BackgroundTelevision (TV) broadcasting is being digitised in South Africa. This provides an opportunity for the rural population to access the Internet through television sets. There is a need to manage the co-existence of television broadcasting and broadband Internet services mainly in the Ultra High Frequency (470 to 854 MHz) bands. The primary user watching TV broadcast services should be protected from unwanted interference generated by the secondary user broadband Internet user. The CSIR has developed a co-existence tool called the geo-location based dynamic spectrum allocation (GL-DSA) system.

This study will identify Television White Spaces (TVWS), which are unoccupied television frequency bands, through the use of the GL-DSA system, based on geo-location. A technique for TVWS technology use in the Digital Television (DTV) Set-Top Box (STB) will be developed to help deliver a combined DTV and TVWS-based Broadband Internet services for rural and underserved communities in South Africa.

ResponseThe purpose of this study is to perform research and development in protocols for DTV-STB and GL-DSA system communication and develop techniques to integrate TVWS technology with the DTV-STBs to deliver combined Digital Television and Broadband Internet services for rural and underserved communities in South Africa.

Future researchFuture research will integrate the developed techniques and support the implementation of interfaces for DTV-STBs that can be manufactured in South Africa. The research is expected to support the Digital TV migration process through partnerships with the public and private sector, including relevant government organs. The CSIR’s global leadership in the area of dynamic spectrum management, future wireless networks and the geo-location spectrum database technology will be used to further develop postgraduate human capital in collaboration with TUT. The collaboration between TUT and the CSIR has already resulted in two PhDs. The current postgraduate study on TVWS technology is benefitting from the previous CSIR-TUT postgraduate research outcomes and engagements.

A framework for an agricultural innovation system in South Africa

Billy Bokako, CSIR

Supervisor: Prof. Mammo Muchie, TUT

Background

The study sought to provide a framework on how to manage innovation and create value and knowledge within the essential oils sector in South Africa.

This research explores the work done by the CSIR, which implements community-based essential oils and medicinal plants projects on behalf of the Department of Science and Technology (DST).

A project in Brits was used as a case study. The work was conducted using industrial engineering tools such as Business Process Modelling and Life Cycle Management.

ResponseInterviews to establish the level of synergies between the different stakeholders were conducted with the DST and the CSIR Enterprise Creation for Development team. In addition, a survey was administered to the fieldworkers to ascertain their involvement in the different aspects of the project. The survey also investigated the experiences of fieldworkers in the essential oils sector. A review of the environmental legislative framework

helped with understanding the impact on the innovation value chain in the agriculture sector.

The responses highlighted areas of improvement, strengths and other factors that were later used to develop a framework for an agricultural innovation system that can be replicated across similar agricultural projects.

ProgressThe study suggested that there were synergies among many of the players. However, there was room for improvement, especially regarding knowledge capture and feedback as well as peer-reviewed articles published. On-site innovation was found to be the major driver of the project. Examples include the use of a mobile distillation unit that could be run on recycled oil, as well as the use of flood irrigation, which requires less energy than other forms of irrigation.

One of the major roles of agricultural investment is to facilitate experimentation on alternate solutions, open market opportunities and develop competitive capabilities that foster economic growth. Different crops were experimented with to establish oil yields, agronomy-related parameters and market feasibility. The project increased market access and created 55 jobs.

One of the main principles of the National System of Innovation is to promote an information society through the creation of knowledge, capturing of knowledge and dissemination of such knowledge. Sector development imperatives necessitate the creation and capturing of knowledge created throughout the value chain. An enormous amount of information was created through this project, however, all this information has not been captured in a way that would benefit the sector.
