Projects
CAE operates several bio-gas power generation, waste treatment, bio-fertiliser & water reclamation plants in South Africa and Namibia, as commercial enterprises, in partnership with our project hosts.
We fulfil our partners’ requirements for appropriate waste stream management & reliable energy provision, while producing valuable bio-fertiliser to improve soil health & crop yields.
2021 – current
Limpopo Dairies Biogas Plant
- In partnership with Limpopo Dairies (South Africa).
- Processes dairy manure & milk effluent produced from dairy cows.
- 9000-tonne capacity bio-digester with in-house gas processing technologies.
- Produced biogas to be utilised in duel-fuel hot water generation systems.
2014 – current
Mariental Bio-Energy
- In partnership with !Aimab Superfarm (Namibia).
- Biogas plant accommodates 4,000 dairy cows in a state-of-the-art milk production facility.
- Design maximises dairy cow manure & wash water treatment.
- Outputs valuable odourless substrate, implemented as high-quality agricultural bio-fertiliser.
- Installation showcases a turbocharged variation of CAE biogas generators (300 kW electrical power).
2013 - current
Namibia Biogas Plant Operation & Electricity Generation
Build, Operate and Maintain’ Service Agreement.
Involves:
Build, Operate and Maintain’ Service Agreement.
Involves:
- the development of automation systems for the City’s Wastewater Treatment Works
- building & operating a biogas power generation plant to produce renewable electricity
- neutralising human sewage to produce stabilised sludge
2011 - current
Total Mixed Ration (TMR) Dairy Biogas Plant
- Complete biogas plant (750 kVA) at large TMR dairy in Western Cape (South Africa).
- Plant achieves wastewater treatment, pathogen control & natural fertiliser production.
- Gas processing & power generation embedded in national grid.
- Represents the first completely mixed, heated & covered in-ground anaerobic digester (CMH CIGAD) in Southern Africa to achieve waste treatment of manure from TMR dairies and maximise power generation.
- New design minimises capital costs to enable the complete project cost to be justified against the current electricity retail value in South Africa.
2013 - 2014
Natural Gas Power Generation
- Provided 1,200 kVA CNG power generation plant to a gas filling station operation (Gauteng, South Africa).
- Plant design includes four modularised 300 kVA CNG generator units.
- Generators controlled & integrated with the power demand of gas filling station
2009 - 2012
Bio-digesters for Piggery Waste Treatment
- ‘Grid-embedded’ biogas power generation plant established at Bela-Bela (South Africa).
- Plant’s design served to evaluate biogas engines’ control technology to meet national grid integration requirements.
- CAE assisted with troubleshooting the operations of the pre-existing bio-digester of foreign design – such support contributed towards CAE’s current biogas plant designs (CMH CIGAD).
- Designs achieve cost-effectiveness, capacity & waste handling flexibility.
2007 - 2008
Umgeni Water/Darvill Bio-digester Feasibility Evaluation
- CAE contracted to evaluate two bio-digester units at Darvill Wastewater Treatment Works (WWTW) and power generation capabilities.
- Extensive on-site troubleshooting & identification of faults, repairs and restoration to nominal operation.
