Project Background Project Milestones
25 May 2005. Green Energy & Technology Middle East (GETME) and Octagon Consolidated Berhad (Octagon) has submitted the proposal for a waste to energy project (Project) which is able to process 2,000 tons/day of municipal solid waste (MSW) and up to 400 tons/day of industrial hazardous waste (IHW).
11 Nov 2007. The Municipality agreed in principal for the development of the Project.
11 Jan 2008. The Municipality request for an independent validation study be conducted for the Project.
7 June 2008. GETME/Octagon and the Ministry of Municipal and Rural Affairs (“Ministry”) signed an agreement for GETME/Octagon to undertake independent validation study comprise the followings:
Technology Validation Study – Stopford Projects Limited (UK), Fides International Consultants Luxemburg and Russian Academy of Sciences, Institute for Electro-Physics and Electric Power
MSW and IHW Waste Study – SAES, Jeddah
Preliminary Environment Assessment – SAES, Jeddah
Financial Feasibility – Ernst & Young Consulting Limited, Jeddah
31 Dec 2008. The Study was submitted to the Municipality and presented on 17 Jan 2009.
22 March 2009. A letter and report submitted to ECRA to consider the power tariff of SAR0.35 kWH for the Project.
Improve the environmental and health standards in the city of and its suburbs through hygienic treatment of MSW.
The project will convert untreated MSW and IHW into renewable energy. This will reduce methane (a potent greenhouse gas) generation from landfills, odour, health hazards and leachate contamination of ground water that are currently being caused as a result of disposal of MSW and IHW.
The project is consistent with government objectives in promoting an environmentally beneficial project that will significantly improve waste management, promote renewable energy generation and reduce the emissions of green house gases.
Reduce requirement of landfill area for dumping of MSW and IHW, thereby freeing up land resources for other socially beneficial usage.
Expand the range of energy generation sources by promoting the development of renewable energy projects to meet a part of the energy requirements.
Promote private sector participation and investment in clean and renewable energy projects.

Technology Track Record Independent Validation and Experience
Russian Academy of Sciences, Institute for Electro-Physics and Electric Power. “Calculations and experiments prove that plasma methods of waste and coal treatment are economically beneficial and ecologically friendly. Plasma generators operating on water vapour are the most promising for treatment of organic-containing waste for syngas production”.
Concept Engineering Design validated by Simon Carves Limited, UK.
Front End Engineering Design undertaken by Stopford Projects Limited, UK (completed)
Detailed engineering design undertaken by Stopford Projects Limited, UK (work in progress)
Gasification Vessel Design and CO Enhancement validated by Stopford Projects Limited and PSE, UK.
Individual process is proven technologies undertaken by companies with strong track record including: Fairport, UK (Waste Receiving, Sorting and RDF Production), Europlasma, FR (Plasma Torches and Reactor Design), La Gas Integral, FR (Gas Processing), Peter Brotherhood, UK (Gas Compression), General Electric, USA (MV Power Generation), Caterpillar, USA (LV Power Generation), EPCC contractors in KSA (Civil and Utilities)
Technology Suitability
Multiple feedstock capability
Capable of receiving, handling, processing and disposing, different types of wastes (e.g., MSW, IHW) concurrently.
Complete destruction of wastes
Plasma gasification process is a NO BURN process hence, it does produce residuals, i.e., fly & bottom ashes as typically found with incinerators.
Fly & bottom ashes are harmful, may contain heavy metals and require secure landfilling. Since plasma gasification does not produced ash, landfilling will no longer be a requirement.
Maximum energy recovery from wastes
Plasma gasification process is designed and engineered to ensure efficient energy recovery from wastes.
Environmentally friendly
Operating at temperature range of about 3,000oC in the Gasification Zone in an oxygen starved environment, are realised in the plasma reactor therefore, plasma gasification process presents no opportunity for formation of hazardous flue gases, e.g., dioxin & furans, SOx and Nox.
Clean Development Mechanism under Kyoto Protocol
Capable for qualification as CDM project, i.e., reduction of emission of methane typically from landfills and reduction of CO2 emission from avoidance of use of fossil fuels for power generation.
