    Introduction
    Waste management in general is becoming an increasingly environmental and health risk problem.

    Environmental legislation and regulations are placing pressure on authorities and industry to improve on existing management processes with a greater focus on recycling with the aim of reducing the footprint of current practices in an ecological and environmentally friendly manner.

    Industry challenges:
    The challenge is to convert a cost into revenue and profit by:
    1. Diverting of all bio-mass waste to Waste to Energy Plants (The management and handling of biomass waste at landfill sites must be avoided)
    2. Reducing landfill site footprints
    3. Reducing the production of methane in landfill sites
    4. Reducing the bad odours of decomposing biomass.
    5. Reducing the cost of transport from collection points to landfill sites by chipping at collection points and transport of chips direct to generation plants.
    6. Development and implementing of new green technologies by all industry partners and stake holders including Authorities, promoting a green and sustainable environment.
    7. Channelling of resources and investment capital to new green technologies.

    Municipal solid waste, agricultural and industrial biomass waste offers a great opportunity for conversion into electricity because it is an untapped resource with consequential negative environmental, economic and social impacts.

    Dry Brayton Cycle Technology

    Extensive research for the last three years developing unique technology that is environmentally friendly and completed verification of all relevant thermodynamic and technology calculations. Verification included universities and independent third party consulting engineers.

    Combined Turbo Compressor and Turbo Generator units using heat from oxidation of biomass for the generation of electricity using no water, no steam, no water treatment and no gas scrubbing

    Note: The technology is not gasification.

    The dry Brayton cycle has the added benefit that it can be integrated with a CSP system allowing seamless migration from sun energy to biomass energy and back, effectively utilizing biomass as a storage battery of energy at night or when it is cloudy.

    Future Development
    The development has reached a stage where the building of a pilot plant to demonstrate the technology is in a planning stage together with the North-West University.

    The co-development with North-West University faculty of Mechanical Engineering is done with a 50% grant from the NRF.

    The technology is proven in its current application (Waste heat recovery for marine applications) and indicated individual capacity is 0,2 to 2,5 MW per unit allowing total plant capacity up to 20 MW

    The technology is unique as it uses no water, no gas treatment or scrubbing and no steam.

    (The working fluid is clean air).

    Any combustible Biomass Waste can be dried and combustion with full oxidation of all bio-carbons is proven to be the most environmentally friendly practice.

    The heat of combustion will be integrated into a dry Brayton Cycle with heat exchangers to generate electricity. (No steam, no water and no scrubbing of gasses)

    All biomass will be chipped at collection points and transferred to the generation plant avoiding handling of the biomass waste at landfill sites.

    The technology can convert biomass waste to electricity at an efficiency of 1 ton dry biomass waste per hour produce 1MW hour of electricity.

    Indicated available resources for this purpose is 1.5 million ton dry biomass for Gauteng

    This relates to a generating capacity of 170 MW or 1.5 million MW h per annum with potential revenue of R 900 million per annum at R 0.60 per kW h

    (If above is produced at the feed in tariff of NERSA for biomass to electricity the revenue will be

    R 1.575 billion per annum at R1.05 per kW h

    Investment opportunity:

    The total investment to realize above is in the order of R 5 billion for equipment and infrastructure development.

    Advantages of the outcome

    One of the outcomes of this is the price of electricity for the Producer (IPP) can be capped independent from imported power, allowing the IPP open opportunity to increase revenue and keep cost down.

    The electricity can be integrated into the local supply grid, reducing the local authority reliance on imported electricity and at the same time mitigating the environmental impact and cost of waste management and converting a cost into revenue.

    The implementation of this technology will create substantial volumes of jobs and commercial opportunities for businesses and local authorities. (1 direct job and 4 indirect jobs per R1 million investments)

    A limited budget for the co-development of the technology is hampering the progress of the project. To address this problem OneGreen Engineering is looking for investment partners to support the development of the pilot plant to demonstrate the proposed technology in an operational environment.

    In this regard OneGreen Engineering can offer an investment opportunity to acquire access to the OneGreen Waste to Energy technology. The technology and process is believed to have great potential in an environment where waste recycling/use has become very important. The technology can make a valuable contribution in the drive towards a green and sustainable economy unlocking investment and commercial potential of the renewable energy sector.
