Analysis of potential energy conservation and emissions reduction in ferrous foundries in the cities of Ekurhuleni and JohannesburgSingo, Shonisani Norman 02 1900 (has links)
The challenge facing South African foundries today are compliance with the environmental legislations while maintaining a high production rate. The focus of this study is to assist foundries to comply with National Environment Management Air Quality Act 39 of 2004. The aim of the study is to achieve a foundry with high production rate with low energy consumption and low emissions, while complying with air quality legislation.
Data was collected from foundries within the Cities of Ekurhuleni and Johannesburg. Foundries were requested to provide information such as the raw materials feed rate, and production rate, emission units, type of energy used and consumption rates. Seventeen foundries participated in this study. Data collected from these foundries assisted in determining the emissions rate generated during production process. Emissions were quantified from the foundries using emission factors. In this study electricity and natural gas were found to be the most preferred source of energy in the foundries. An energy intensity relationship exists, for both electricity and natural gas and its production rate. The results indicated efficiency of energy intensity of 0.25 to 6.37 GJ/Tonne in the foundries.
Selection of furnace used by the facilities plays an important role on the energy saving and emission reduction. Foundries that need to reduce particulate matters on the melting should consider electric arc furnace because it generate less particulate matters than open hearth. Foundries that would like to reduce sulphur dioxide should consider electric arc furnace rather than open hearth. Foundries that have challenges on the NOx should consider open hearth furnace than electric arc. An installation of suitable abatement systems should also be considered for the reduction of other pollutants. Results indicated that installation of abatement system at 95% efficiency will decrease emission rates by twenty times. Study reveals that 3.93 kg is polluted to the atmosphere per tonne of production in a month for the foundries that do not have abatement system and installation of abatement system will decrease air pollution from 3.93 to 0.20 kg per tonne to the atmosphere / Civil and Chemical Engineering / M.

Energy management in the South African hotel industryFouejio-Tsobze, Brice January 2010 (has links)
Thesis (MTech (Electrical Engineering))--Cape Peninsula University of Technology, 2010. / In recent years, the South African hotel industry has experienced increasing demand for hotel's
services. At the same time, mounting costs of energy affects energy performance and public
image. Energy management is a new approach to address those widespread problems. This
study aimed to suggest good management practices and develop a "self-help" approach, to
reduce the demand and costs of energy for the South Africa hotel industry. This is expected to
result in monetary savings and conservation of energy resources. This has been done by
conducting survey within seven selected hotels in Cape Town, metropolitan of South Africa.
In addition, through the "self-help" guide, approaches to energy management system are also
described, showing the ways for hotels to achieve better energy performance. Potentials for
savings from good housekeeping are estimated to 10 - 15%. The "self-help" guide is
recommended to be improved through implementation in pilot hotels; and the proposal set of
benchmarks need to be different for hotels in different provinces of South Africa considering the
differences in climate conditions.
The result of this study range from presenting the energy conservation awareness, barriers,
method of conservation, financial and institution mechanisms, policy measures, status of energy
use and propose strategy to develop a "Self-help" guide for energy management in South
African Hotel industry. It has been found that energy monitoring has been done in the South
African Cape Town hotels. From the total energy consumed by this industry, electricity accounts
80% of it of which air conditioning takes the biggest share (about 50%) and the remaining for
Liquefied Petroleum Gas (LPG), diesel and others fuels. In addition, through the "self-help" guide, approaches to energy management system are also
described, showing the ways for hotels to achieve better energy performance. Potentials for
savings from good housekeeping are estimated to 10 - 15%. The "self-help" guide is
recommended to be improved through implementation in pilot hotels; and the proposal set of
benchmarks need to be different for hotels in different provinces of South Africa considering the
differences in climate conditions.

The value of an energy efficiency strategy : the case for Pioneer FoodsLe Roux, Andries 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2008. / ENGLISH ABSTRACT: This research study explored energy efficiency and the possible implications for a South
African company, the Pioneer Foods Group (Pioneer Foods).
“What value could Pioneer Foods derive from an energy efficiency strategy?” is the
research question posed in this study.
The case study analysis revealed that Pioneer Foods recently listed on the Johannesburg
Stock Exchange and therefore needed to implement an environmental management
strategy as part of their carbon footprint reporting. Energy efficiency turned out to be one
aspect that could have a significant impact on their carbon footprint.
The most important barrier to energy efficiency identified at Pioneer Foods was found to
be the lack of real-time electrical consumption information as this could result in a lack of
ownership taken by mill management. Further barriers included the use of wrong
information for benchmarking purposes as well as a possible misunderstanding of the
different electricity tariffs shown on the electrical utility bill.
Possible ways to overcome the barriers to energy efficiency at Pioneer Foods included
installation of energy meters for real-time monitoring of the energy consumption,
empowerment of people to ensure buy-in, as well as key performance indicators for mill
managers linked to energy efficiency.
It was suggested that the energy efficiency strategy be implemented in stages covering
short-term, medium-term and long-term objectives. This way the implementation process
would seem less intrusive to people and also give the energy efficiency team the
opportunity to learn more and perhaps adjust the strategy throughout the implementation
process.
This research project should act as a starting point for Pioneer Foods to grow from being
unconsciously incompetent to becoming consciously competent in the field of energy
efficiency. The observations made throughout this study, should convince companies that
energy efficiency should not just matter to high energy users. All companies should
explore their own drivers for implementing energy efficiency and act on it. / AFRIKAANSE OPSOMMING: Hierdie navorsingstudie het die effektiewe gebruik van energie, en die moontlike
implikasies vir ‘n Suid Afrikaanse maatskappy, die Pioneer Voedsel Groep (Pioneer
Voedsel) ondersoek.
“Watter waarde sou Pioneer Voedsel kon put uit ‘n energie-effektiwiteit-strategie?”
is die navorsingsvraag wat in hierdie studie gestel is.
Uit die analise blyk dat Pioneer Voedsel onlangs op die Johannesburgse Effektebeurs
genoteer is. Daar word dus van hulle verwag om ‘n omgewingsbestuur-strategie in plek te
stel as deel van hul koolstofvoetspoor-verslaggewing. Dit blyk dat energie-effektiwiteit een
aspek is wat ‘n groot impak op hulle koolstofvoetspoor kan hê.
Die grootste struikelblok tot energie-effektiwiteit by Pioneer Voedsel geïdentifiseer, was die
tekort aan intydse elektriese verbruiksinligting. Dit kan veroorsaak dat die bestuur nie
eienaarskap neem van energie-effektiwiteit nie. Verdere struikelblokke sluit in die gebruik
van foutiewe inligting vir metingsdoeleindes asook ‘n moontlike gebrek aan begrip van die
verskillende elektrisiteitstariewe uiteengesit op die elektrisiteitsrekening.
Moontlike maniere om die struikelblokke by Pioneer Voedsel te oorkom sluit in die
installasie van energiemeters vir intydse monitering van energieverbruik, bemagtiging van
mense om inkoop te verseker, en sleutelprestasie-aanwysers vir bestuurders gekoppel
aan energie-effektiwiteit.
Dit word voorgestel dat die energie-effektiwiteit-strategie in fases geïmplementeer word
om sodoende kort-, medium- en langtermyn-mikpunte te bereik. Sodoende sal die
implementering van die proses minder indringend vir personeel wees. Dit gee ook die
energie-effektiwiteit-span die kans om meer te leer asook die strategie aan te pas soos
nodig tydens die implementeringsproses.
Hierde navorsingsprojek moet dien as die vertrekpunt vir Pioneer Voedsel om te groei van
onwetend onbekwaam tot wetend bekwaam in die veld van energie-effektiwiteit. Verder
behoort dit maatskappye te oortuig dat energie-effektiwiteit nie net ‘n verskil maak vir hoë
energie verbruikers nie, maar dat alle maatskappye hulle eie drywers vir die implementering van energie-effektiwiteit behoort te identifiseer en daarvolgens
aksiestappe te neem.

Mapping the transitional pathway to low-carbon homes in South AfricaGeszler, Dominique Marguerite January 2017 (has links)
A dissertation submitted in fulfilment of the requirements for the degree of Master of Architecture to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, Johannesburg, 2017 / Based on a complementary framework guided by the Delphi method for the business-as-usual (BAU) forecast and the backcasting method for envisioning the desired future state, the study finds that by 2050, South Africa will have reached its goal of 80% reduction of CO₂ emissions from the middle-income home sub-sector, through a middle-loading (ML) transition pathway. This pathway was selected from among four alternative pathways because of its ability to mindfully facilitate the required transformational changes in behaviour and lifestyle, especially through support by means of responsive nudging incentives and mandatory policies, responsive technology innovations and market transformations.
The study also applied multiple-level actors (MLA) principles towards the identified four primary pathway-options in CO₂ emissions reduction in the sub-sector, which are front-loading (FL), back-loading (BL), even-loading (EL) and middle-loading (ML). The study further provided substantial motivation for ML as the preferred pathway for South Africa’s transitioning to low-carbon homes by 2050. This reinterpreted transition model of orchestrating transformative change depicted how iterative responses to conflicting accelerator- and inhibitor-factors enabled low-carbon mitigation interventions in the sub-sector, thus facilitating an equitable country-level contribution towards the global goal of stabilising global warming below the scientifically-guided threshold of 2°C by 2050. A co-evolutionary approach will be required on multiple-levels with significant pressures that will overcome systemsinertia in order to achieve the transition to low-carbon middle-income homes in South Africa. The main findings of this study can contribute towards policy tools to guide deeper structural transformations of both society and economy in pursuit of improved/equitable well-being and prosperity while ensuring survival within finite planetary resources. In particular, the process of visioning and pathway-frameworks under backcasting has been adequately substantiated to allow for adaptation to alternative applications in similar studies for South Africa and internationally as well. / XL2018

Regulation of energy efficiency by voluntary agreement : South Africa's energy efficiency accord.Jackson, Thomas. January 2008 (has links)
Energy efficiency is an issue currently generating huge interest as a potentially costeffective
solution to the twin challenges of environmental pollution from energy production,
and the increasing scarcity of energy resources. This research aims to interrogate the
practicalities of regulation of energy efficiency to ask what scope there is for public-led
encouragement of greater energy savings in industry. Shortcomings of current theory
addressed include a discounting of the impact of heterogeneity of industrial activity on
prospects to effectively regulate for energy efficiency, and a conflation of the different
aspects of societal functioning to which energy efficiency regulations and incentives can
be applied. The research argues that the scope for energy savings has been exaggerated
and the factors which drive pursuit of energy efficiency within firms of different sizes poorly
understood and articulated. The Voluntary Agreement form of environmental regulation is
assessed for its applicability to regulating for energy efficiency in the context of these
characteristics of energy efficiency in industrial settings. An in-depth interview approach
with core participants in an example of a Voluntary Agreement for energy efficiency in
South Africa, the Energy Efficiency Accord (Accord), reveals the difficulties of regulating
for specific technologies, the generally targeted nature of energy efficiency incentive
schemes which provide household and commercial-type programmes to heavy industry,
and the fact that environmental objectives and capacities are highly developed within firms
interviewed and in most cases precede participation in Accord activities. The inference is
that participation at this stage of the Accord's existence is driven by the need to develop
and maintain relations between key stakeholders, and to exploit opportunities to influence
the form of energy efficiency regulation enacted as opposed to the need to obtain forms of
technical guidance. The particular pattern of participation in the Accord is argued to result
in part from the historical dominance of large, energy-intensive firms in South Africa, and
to be consistent with the theory that the more energy-intensive firms in a society will be
motivated to participate in voluntary initiatives such as the Accord. / Thesis (M.A.)-University of KwaZulu-Natal, Durban, 2008.

Energy efficiency at a South African higher education institution: a case study of the Auckland Park Kingsway campus, University of JohannesburgMaistry, Nandariani 30 June 2014 (has links)
M.Phil. (Energy Studies) / In recent years, the costs of electricity in South Africa have increased enormously, thus, most institutions of higher education are seeking ways to manage their utility costs by reducing consumption rates. Hampering their initiatives, however, is the fact that South Africa in general, and buildings in particular, lag the world in knowledge and implementation of demand side management strategies. This case study outlines the efforts of a large metropolitan university in Gauteng to examine the implementation of energy efficiency within the context of the green or sustainable campus movement. The study comprises three core parts: analysis of electricity consumption data; identification of institutional barriers inhibiting implementation of energy efficiency projects, and, lastly establishing key role players responsible for effective implementation. The study found that seasonality and the campus academic calendar both have profound effects on energy consumption. High demand coincides with winter and a distinct correlation was found between peak consumption and core working hours. Consumption peaked at an average of 2 500 kWh during active ‘in-session’ periods. Less active, ‘out-of-session periods’ recorded an average peak of 2 250 kWh. The lowest average peak consumption of 2 100 kWh occurred during ‘recess’ periods. Similar patterns were evident for the maximum demand. It was evident that the university had a high base load (between 1 300 kWh and 1 650 kWh). This high base load could be attributed mainly to the heating and cooling system. To stimulate decision making towards improved options, an energy savings financial model was developed to provide a tool for calculating the return on investment period for energy efficiency projects. Interviews conducted with key role players (in the university’s operations, academic and management divisions) and a staff questionnaire were used to establish the main barriers to energy efficiency implementation: a) the absence of an energy policy; b) a general low level of awareness of institutional energy efficiency activities and (c) the shortage of dedicated, skilled staff to implement energy efficiency projects. The managerial, operational, and financial divisions are arguably the key role players in energy efficiency projects. Lastly, leadership commitment from the highest levels of the university is required. The novel contribution of this thesis is through combining technological and behavioural approaches to energy efficiency at a tertiary institution through a mixed method study design. Key recommendations are presented to stimulate energy efficiency implementation.

Developing SA's solar water heater industry : identifying key success factors for future growth / Developing South Africa's solar water heater industry : identifying key success factors for future growthHardie, Mignon 03 1900 (has links)
Thesis (MBA)--University of Stellenbosch, 2011. / The government has stated its intentions to increase the usage of solar water heating (SWH) through its National Solar Water Heater Programme (NSWHP). As described in the report, increased adoption of SWH would have a number of benefits for South Africa. Firstly, replacement of electric geysers by SWHs would contribute to the meeting of energy efficiency targets through the reduction of energy consumption. Secondly, the widespread adoption of SWHs would help SA to meet its renewable energy targets. Thirdly, it would result in growth in the SWH industry, including the manufacturing, installation and related sectors, thereby contributing to an increase in 'green' jobs. It would have the socio-economic benefit of energy security for South Africans.
The research report looks at the factors influencing the SWH industry's future growth from the point of view of the suppliers. It considers the interplay between consumers (market demand), government (public policy measures) and suppliers (businesses providing services related to SWH) to determine how government can support industry, how suppliers can grow their business and industry and how government and industry can work together to create the conditions for sustained market demand.
As is discussed in the literature review, there are certain barriers to the adoption of SWH technology. As such, government intervention is needed to help overcome these barriers. The literature review recounts the available policy tools and considers how these have been applied in other countries to stimulate demand for SWHs and to support the local industry.
The research report takes the form of a survey of SWH suppliers with the following aims:
- To describe the industry in terms of its age, maturity and ability to scale up;
- To determine the major barriers to the industry's growth;
- To specify the appropriate public policy tools to overcome these obstacles to growth;
- To establish how confident the industry is in the NSWHP and government efforts to promote the industry;
- To provide a list of key success factors that are required for the industry's long-term, sustainable development.
The report concludes that there are three criteria that would help the industry to become sustainable: market demand certainty, investment confidence and positive competition. Certainty of future market demand would build confidence in the industry for investors. In turn, increased investment would benefit the forces of positive competition.

Overcoming energy constraints on future development in Stellenbosch through energy efficiency : retrofitting of solar hot water heaters and gas stoves in middle and high income households in the residential sectorNyabadza, Munyaradzi Christine 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: South Africa faces an energy crisis which presents itself in two forms; electricity generation dominated by coal fired power stations and current electricity supply capacity being unable to meet growth in demand. South Africa urgently requires new generation capacity: however, power stations take time to plan, construct and commission, meaning that South Africa has to consider other options to meet electricity demand. This necessitates quick and innovative ways of meeting future demand.
Energy efficiency has been identified as “a low hanging fruit” on the energy tree to address supply constraints and reduce energy related greenhouse gas emissions. There are various energy efficiency programmes aimed at raising awareness of measures that households can take to reduce energy consumption. Some of South Africa’s key objectives of energy efficiency in the residential sector are to mitigate the effect of peak demand on power capacity and to introduce state of the art technologies. In terms of these technologies, there is an overlap between energy efficiency and renewable energy.
The widespread installation of renewable energy technologies such as SWHs has the potential to delay the need to construct new power stations. SWHs are a viable renewable energy option for South Africa. It is a mature and proven technology with the potential to address South Africa’s electricity capacity problems. Not only does a SWH provide financial savings to the customer in the long run but it offers the additional benefit of a reduction in greenhouse gas emissions to society. Although awareness of the benefits of solar water heaters is increasing, SWH uptake remains low. However the uptake is increasing due to; a SWH rebate offered through Eskom, electricity price increases which are forcing consumers to seek alternatives and a national building code requiring energy efficient water heating in new buildings which is expected to come into effect in 2012. Liquid Petroleum Gas is a low carbon emitting source of fuel for cooking. In South Africa, middle–high income households rely on the electric stove for cooking. Cooking contributes to electricity peak demand. Reducing electricity demand by replacing the electric stove would help in reducing electricity peak demand from the grid. LPG use has been increasing due to the following reasons; electricity supply shortages, shifting government policy on LPG and increasing electricity tariffs forcing lifestyle changes.
This case study sought to investigate the opportunities, as well as the barriers for a Stellenbosch municipality - initiated energy efficiency programme. In terms of energy supply and demand management, the municipality has identified energy efficiency and the introduction of renewable energy sources as options for achieving sustainability. One of the barriers facing energy efficient technologies is up-front costs in the case of SWHs and the cost of appropriate equipment such as gas stoves in the case LPG. The study sought to investigate financial mechanisms that the municipality could use to overcome these barriers and promote the use of SWH and gas stove in the residential sector. Data was collected through a combination of a mini Delphi – expert opinion technique, questionnaires, secondary data analysis, telephone and personal interviews with solar water heater industry stakeholders, LPG industry stakeholders and municipal officials.
The conclusion drawn from this research is that Stellenbosch Municipality can initiate its own energy efficiency programme instead of waiting for national government. Although the municipality can initiate an energy efficiency programme, it needs to find another institution to fund the programme. Funding mechanisms however do overcome the barrier of high up -front costs and high gas equipment costs making energy efficient technologies affordable. / AFRIKAANSE OPSOMMING: Suid-Afrika staan voor ʼn energiekrisis wat op twee maniere gestalte kry: elektrisiteitsopwekking wat oorheers word deur steenkoolkragstasies en huidige elektrisiteitsvoorsieningsvermoë wat nie in die groeiende aanvraag kan voorsien nie. Suid-Afrika benodig dringend nuwe kragontwikkelingsvermoë. Dit neem egter tyd om kragstasies te beplan, op te rig en in diens te stel, wat beteken dat Suid-Afrika ander opsies moet oorweeg om in elektrisiteitsaanvraag te voorsien. Dit noodsaak vinnige en innoverende maniere om in toekomstige aanvraag te voorsien.
Energierendement is as “ʼn laaghangende vrug” op die energieboom geïdentifiseer ten einde beperkings in kragvoorsiening die hoof te bied en kweekhuisgasuitlatings wat met energie verband hou te verminder. Daar is verskeie energiebesparingsprogramme wat ten doel het om die bewustheid te versterk van maatreëls wat huishoudings kan volg om energieverbruik te verminder. Van Suid-Afrika se vernaamste doelstellings ten opsigte van energierendement in die residensiële sektor is om die uitwerking van spitsaanvraag op kragvermoë te verlig en om die jongste tegnologie in te voer. Ingevolge hierdie tegnologieë is daar ʼn oorvleueling tussen energierendement en hernubare energie.
Die algemene installering van hernubare energietegnologieë, soos sonkragwaterverwarming (SWV), het die potensiaal om die noodsaaklikheid van die oprigting van nuwe kragstasies uit te stel. SWV is ʼn lewensvatbare nuwe energieopsie vir Suid-Afrika. Dit is ʼn ontwikkelde en bewese tegnologie met die potensiaal om Suid-Afrika se probleme ten opsigte van elektrisiteitsvermoë die hoof te bied. SWV sorg nie slegs vir die kliënt vir finansiële besparing op die lang duur nie, maar dit bied ook vir die samelewing die bykomende voordeel van ʼn afname in kweekhuisgasuitlatings. Alhoewel die bewustheid van die voordele van sonkragwaterverwarming toeneem, bly die gebruik van SWV laag. Die gebruik is egter besig om toe te neem vanweë ʼn SWV-korting wat deur Eskom aangebied word, elektrisiteitsprysverhogings wat verbruikers dwing om alternatiewe te soek, en ʼn nasionale boureglement wat energiedoeltreffende waterverwarming in nuwe geboue vereis en wat na verwagting in 2012 in werking sal tree.
Vloeibare petroleumgas is ʼn brandstofbron wat vir kook gebruik word en wat ʼn lae koolstofvrystelling het. In Suid-Afrika gebruik huishoudings met ʼn middelhoë inkomste die elektriese stoof om te kook. Kook dra by tot elektrisiteitspitsaanvraag. Die vermindering in elektrisiteitsaanvraag deur die vervanging van die elektriese stoof kan help om die elektrisiteitspitsaanvraag op die netwerk te verlaag. Die gebruik van VPG het toegeneem weens die volgende redes: elektrisiteitsvoorsieningstekorte, veranderende regeringsbeleid ten opsigte van VPG en die verhoging in elektrisiteitstariewe wat veranderinge in lewenstyl afdwing.
Hierdie gevallestudie het gepoog om die geleenthede, sowel as die hindernisse vir ʼn energierendementprogram wat deur Stellenbosch Munisipaliteit geïnisieer is, te ondersoek. Ten opsigte van energievoorsiening en -aanvraagbestuur het die munisipaliteit energierendement geïdentifiseer en die ingebruikneming van hernubare-energiebronne as opsies om volhoubaarheid te bereik. Een van die hindernisse waarvoor energierenderende tegnologieë te staan kom, is voorkostes in die geval van SWV en die koste van toepaslike toerusting soos gasstowe in die geval VPG. Die studie het ondersoek ingestel na die finansiële meganismes wat die munisipaliteit sou kon gebruik om hierdie hindernisse te bowe te kom en die gebruik van SWV en gasstowe in die residensiële sektor te bevorder. Data is ingevorder deur middel van ʼn kombinasie van ʼn mini-Delphi – kennermeningtegniek, vraelyste, sekondêre data-ontleding, telefoon- en persoonlike onderhoude met belanghebbendes in die sonkragwaterverwarmingsbedryf, belanghebbendes in die VPG-bedryf en munisipale amptenare.
Die gevolgtrekking wat uit hierdie navorsing gemaak word, is dat Stellenbosch Munisipaliteit sy eie energierendementprogram kan inisieer in plaas daarvan om vir nasionale regering te wag. Alhoewel die munisipaliteit ʼn energierendementprogram kan inisieer, moet dit ʼn ander instelling kry om die program te befonds. Befondsingsmeganismes oorkom egter die struikelblok van hoë voorkostes en hoë kostes van gastoerusting wat energierenderende tegnologieë bekostigbaar maak.

A study into the slow rate of energy conservation in the base metal refinery of Anglo American Platinum (Amplats)Badenhorst, Leon 03 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2012. / The consumption of energy results in environmental costs, which include resource shortages, air pollution and radioactive wastes. Due to the economic cost associated, more and more Western industrial organisations are investing in innovative technologies to reduce energy consumption through improved thermal insulation of buildings, modifying equipment and by using energy-saving devices. The organisations are, however, not assured of any savings unless employees handle apparatus and equipment in a manner that conserves energy. Therefore, the important question to answer is how organisational behaviour can be changed to improve and enhance energy conservation efforts.
Anglo American Platinum (Amplats) has identified that it needs to change its operations to conserve energy, thus ultimately conserving the planet. The company has identified an internal goal of reducing its energy consumption by fifteen percent, without sacrificing output, over a period of ten years from 2004. Current (2011) energy consumption at the Rustenburg Base Metals Refinery (RBMR) facility indicates that the mentioned goal does not seem achievable in 2014 as anticipated.
The proposition to this phenomenon is that the prevailing culture at RBMR is not conducive to a conservation culture as required to conserve energy. Organisational culture is the pattern of values, norms, beliefs, attitudes and assumptions that shape the ways in which people behave and things get done. This hypothesis was tested with a culture survey in the form of an environmental questionnaire. The findings from the questionnaire confirm cultural barriers to achieving centralised targets and goals. Responses to the questionnaire indicated that the organisation does not measure energy conservation efforts accurately and that the information on how to attain the required conservation is not sufficient. The respondents further indicated that they have very limited input into energy conservation efforts and that trust issues present themselves as barriers to achieving set goals and targets. The prevailing perception by the respondents is that inadequate recognition systems are in place to drive the required savings.
A surprising finding of the research is that the level of education of the respondents showed no significance with regard to energy conservation and the environment in general. A second interesting finding was that most respondents felt that they could do something to conserve energy and thereby conserve the environment. The challenge facing Amplats is to transform this awareness into a vehicle that will produce significant and sustainable results.
Clear and decisive action will be required to bring about cultural change.
