Cleaning up Cape Town's residual waste and enabling a circular economy.
Historically South Africa has relied heavily of depositing our wastes in the ground, in a process called land filling...
With increased land pressures and shortages for developments around large cities and the increased risk of ground water contamination and methane gas releases, a new way of treating and beneficiating waste is required.
The responsibility for proper waste disposal lies with the generator.
Municipalities need to try their best to enable... proper separation of waste and logistics management to the appropriate waste disposal mechanisms, taking into account an ever changing environment and legislation.
Clean materials recovery facility is suitable for co-mingled
recyclables that are source separated. A small fraction of material...
from these sites are also not recoverable and this will end up in a landfill or can be further processed to produce energy.
Dirty materials recovery facility; general waste can be separated in such a facility to produce organics for biogas plants, some dirty recyclables, refuse derived fuels or inputs into a waste to energy plant. The New Horizons Materials Recovery plant is such a facility.
Biogas is made from an anaerobic digestion process which occurs in large fermenting vessels....
Only putrescible organic wastes are converted and therefore source or mechanically seperated organic feedstock is required. Many industrial and farming wastes are organic in nature and can be directly utilised by this plant. New Horizons Waste to Energy is capable of this function.
Thermal waste to energy is the last stop for combustible residual wastes....
The outputs form this facility are mainly electricity, heat and ash. Ash can be further reprocessed for aggregate use and metals recovery.
Waste Mart is currently a supplier of waste management and logistics services.
Waste is collected from houses and businesses by the municipality or private contractors....
Depending on the waste separation program different vehicles pick up different wastes. It is imperative that these wastes get channelled to the correct processing facilities to prevent excess landfilling. Initiatives are underway to improve this.
Witech is actively getting projects off the ground in Africa. Please visit their website for more info.
This type of waste is most abundant but should be reduced in the future as it makes recovery and reuse the most difficult. This can be processed in a dirty Material Recovery Facility but produces considerable unusable residues that are best suited for thermal processing to energy.
Some communities separate recyclables into special bags (coloured or clear). This can be taken to clean Material Recovery Facility for separation into reusable recyclables.
With source separation and many industrial clients there is a large amount of organic waste that is landfilled. This can be composted or used in a biogas process. The biogas process also produces an organic fertiliser that can substitute or add to a compost product.
Residual wastes are left over after most of the recyclables are removed. These wastes typically are too intermingled or contaminated and need to be utilised for thermal energy production or will be landfilled. Sometimes we process this waste stream further to remove contaminants such as ceramics and sand before processing in an incineration plant.
Mustapha Energy is a novel waste to energy development that aims to unlock the potential at the end of the recycling and recovery process to add additional value by producing energy. The project aims to utilise state of the art and proven thermal technology to achieve this goal.
The Mustapha Energy project development is spearheaded by Witech Africa which has over 20 years combined team experience in the field. The project is funded by The Nordic Development Fund through the Environment and Energy Partnership as well as Moshading Capital and Waste Mart....
Waste Mart is the main waste supply partner and the property supplier for the location of the main development. Mustapha Energy has also partnered with the Waste Transformation 4 Energy Association, an industry representative association for the residual waste to energy industry using thermal technologies.
The association will be doing studies and information sessions with the local communities and stakeholders in the project. Both WT4E Association and Mustapha Energy are women led organizations.
The project aims to bring substantial local and foreign investment into the Western Cape to build a flagship project to process between 15 to 700 tons per day of residual unrecyclable municipal waste to energy....The project will be able to produce between 0.2 MWe and 10 MWe. The project technology will comply with the highest international emission standards to ensure a negligible impact to the environment and a substantial improvement over other forms of local heating and electricity supply. The waste processing hub that this project will be a corner stone of is based in the Athlone area with potential further extensions into Industrial areas in Epping and Bellville.
The project adds constructively to the waste economy be enabling recycling projects such as the New Horizons Waste to Energy project to efficiently utilise residues and produce heat and energy for the recycling and biogas production processes.
The South African Government has gazetted the amendment to Schedule 2 of the Electricity Regulation Act, which increases the licencing-exemption threshold for electricity generation – embedded generation connected to the grid – from 1MW to 100MW. This may present business opportunities for Finnish technology supply in the areas of Waste-to-Energy (W2E), biomass and energy storage. Energy-intensive consumers such as mines and smelters, as well as medium-sized businesses, are looking to diversify their energy supply sources due to expensive and unreliable energy supply by power utility Eskom.
“The Gauteng Infrastructure Financing Agency (GIFA) has a R17-billion waste-to-energy Public Private Partnership project for the three Metros in the province (Johannesburg, Ekurhuleni and Tshwane).”
Witech Africa will assess the feasibility of a modular #wastetoenergy plant that will generate 2.7 MW of electricity and thermal energy from municipal solid waste in Cape Town.
The integrated plant technology developed by Finnish company WOIMA Corporation has the potential to transform waste management in South Africa, providing clean energy to the grid and reducing the need for load shedding. When operational, the plant is expected to divert more than 60,000 tonnes of waste from landfill and significantly reduce greenhouse gas emissions. Additionally, Witech plans to establish a local non-profit to educate schoolchildren and the community about waste management.
“Witech Africa is a South African company that develops waste management solutions and deploys waste-to-energy technologies suitable for small to large-scale applications in Africa.”
President Cyril Ramaphosa on Thursday moved to deal with the electricity supply crisis harming the South African economy. He has announced a partial liberalisation of the sector by lifting the limit on self-generation of power from 1MW to 100MW.
The move, which includes the ability to sell excess capacity into the grid, is expected to take pressure off state-owned electricity utility Eskom — although not immediately — as private companies use the amended regulations to build their own power generation plants.
The significant shift in the amount of electricity that can be self-generated – mineral resources & energy minister Gwede Mantashe had wanted to lift the cap from 1MW to only 10MW – should eventually help reduce, if not eliminate, the load shedding that is holding back economic growth.
“Mustapha Energy can now deliver 13 MW through its projects in Cape Town. Thank you Mr. President.”
Mustapha Energy is a special purpose development for a waste to energy facility that utilises residual waste from recycling activities in Athlone to produce electricity, heat, recycled metals and aggregate products. The project is supported by the Nordic Development Fund through the Environment and Energy Partnership. The lead developer is Witech Africa, and the waste supply and JV partner is WasteMart, a stallwart of the waste management industry in Cape Town.

“Very early on in my career as a clinician I was frustrated by the fact that I could only make a difference one patient at a time. The treatment offered did not significantly alter the socio-economic determinants of illness that presented in my practice. My passion for impacting the mental health and well being has led me to investments that are focused on social impact and sustainability. At the Mina Foundation we manufacture and distribute menstrual cups to menstruators primarily of school going age. Our goal is to not only to end period poverty in South Africa and beyond our borders, to keep girls in school and to have a positive impact on the environment..”
“Waste Mart has always been a keen supporter of alternative waste management technologies and techniques to reduce the disposal of waste to landfill, which is both costly and environmentally damaging.
