The integrated Global Olivine Sustainable Resource Recycling Facility (GO – SRRF) technology has been peer-reviewed by leading international experts. Global Olivine Limited maintains associations with a key input panel in which world-leading expertise from many international companies is represented. The UK Environmental Authority reported the process as ‘best available technology’ in their justification for issuing an environmental permit for a Sustainable Resource Recycling Facility at Peterborough.
The vast majority of existing waste-to-energy processes claiming ‘sustainability’ are incomplete, resulting in system inefficiencies and toxic residue being returned to the air, water and soil, often in more highly concentrated forms. These fragmented processes merely change the geographic location of toxic wastes which further pollute the environment and should not claim ‘sustainability’.
Using advanced conversion technology, the GO – SRRF has created a unique, comprehensive and truly sustainable resource recycling system that complies with the world’s highest emission standards for a thermal power plant.

The GO SRRF integrated system produces energy and saleable by-products from society’s waste, free from harmful emissions, with zero waste to landfill.
The Global Olivine goal is to work in partnership with governments, communities and businesses to deliver sustainable solutions to regional energy, waste, recycling and water desalination needs. Through the integration of processes and by-product industries, a GO – SRRF converts industrial, household, and agricultural waste to valuable resources by recovering energy and making a major contribution to the national grid while powering the manufacture of a range of valuable and saleable products from recycled waste materials. These on-site industries are very power efficient and contribute their waste heat to power generation.
How It Works
A Global Olivine Sustainable Resource Recycling Facility benefits communities, municipalities, countries, and the environment:
• Processes between 1.87 and 2.5 million tonnes of waste p. a. @ 10.4
GJ/T to 7.7 GJ/T average calorific values which is equivalent to 2.636
million barrels of oil. Because of excellent gas scrubbing and high
process efficiency, the plant is able to cleanly use high sulphur coal
as a supplementary fuel which can be replaced by an expanding waste
• Integrates up to twenty two by-product industries, transforming all forms of waste, including hazardous materials and sewage sludge, which produce up to 44 useful, highly competitive and marketable products. Everything is recycled; no products, toxic or otherwise, are sent to landfill.
• The plant’s carbon footprint is vastly reduced by the integration of its onsite industries where the waste products or waste heat from one process becomes the raw material or energy for another that eliminates emission of landfill gas emitted to atmosphere. The dismal efficiency of industry-prevalent landfill gas collection and exported generation provide the SRRF plant with 1.9 million tonnes of CO2 credit/yr in a Western Australia study. There is potential for another one million tonnes/yr as a result of energy savings by the by-product industries from their energy savings stemming from shared infrastructure, combined with raw materials savings and the associated energy ingredient saving from mitigated production and transport. A first plant audit study at commissioning will verify quantification of these savings and the international standards and methodology for calculating the parameters for such CO2 credits will require modification to accommodate GO process efficiencies and may well see credits increase by around half a million tonnes.
• A 48% efficient gas fired, dual cycle generator produces 0.42 tonnes of fossil fuel derived CO2 per MW-h of electricity produced. A 31.4% efficient GO-SRRF produces 0.22 (Fiji) and 0.38 tonnes (UK) of fossil fuel-derived CO2 per MW-h produced dependant, on the fuel mix. GO’s superior performance makes it the most thermally efficient power generator available in terms of fossil fuel use.
• The plant’s multiple revenue streams allow for reduced power charges and tipping fees and reduce the cost of products made by onsite by-product industries. This characteristic also negates sensitivity to fuel and electricity prices of existing methods of power generation.
• All plant components use proven technologies that have been fully tested in applications worldwide, mitigating commercial risk.
• Because the plant is constructed by a consortium of committed parties, project deliverability risk is further minimised.
• Proprietary optomised computer controlled beds that manages multiple source fuel supply,combined with prioritised preheated combustion air from numerous plant waste heat recovery sources and 8 different supply sourced containers with indexed calorific values This system displaces the currently used pit and grab cranes with their odour, fire and hap hasard heat value selection. GO’s heat management , with long retention, higher gas residence temperature assures complete combustion and enables a high temperature gas scrub that vastly extends boiler life and limits heat and acid spikes. The multiple UHTC’s with these attributes effect a near uniform flue gas characteristic that with the exchange of radiant heat recovery for complete combustion and an economiser design that enables 16.5% additional heat recovery without acid corrosion effect, which still accommodates a considerable net gain in steam production efficiency.
• The advanced gasification plant’s emission levels are insignificant; there are no detectable fumes or odours to atmosphere so no consequent risks to public health.
• By utilising N-1 power production, dynamic Megavar production, grid support and spinning reserve are available and plant “down time” is eliminated. This ensures reliable waste disposal and power generation; the plant provides extensive grid stability and the consistent ability to process contracted waste and generate and export contracted power.
• Power export from the site can be reduced at night by operating the foundry and other high power use by-product industries on a night shift. Power export is between 140MW and 186MW. This equals about 1,427,500 MWh over a year. Household power consumption varies from 0 to 6.25 MWh per year, depending on standard of living and whether gas is used for heating. (UK is up to 4.25 MWh per household per year, and NZ is up to 6.25 MWh per household per year). If a figure of 5 MWh per household per year is used, then the power output is equivalent to somewhat more than the energy requirements of 285,500 households.
• Purpose-designed container ships are used for a large portion of waste transportation, reducing road traffic significantly and allowing the use of waste from expanded local regions and close-proximity islands, further lowering the carbon footprint and providing fuel for the plant.
• Operating at a thermal efficiency of 92.9% – 94.0% (when the asphalt plant is operating) and 31.4% electrical efficiency (compared to 18% – 20% for other waste-to-energy technologies), a GO-SRRF produces 30% – 35% more power than most competing processes per tonne of waste. Advanced heat recovery technology means more power is generated for the same amount of CO2 produced, regardless of origin, thereby reducing atmospheric CO2 levels.
• The aggregated cost of the project and its industries is significantly less than the cost of building the same standalone power, water and by-products industries.
• GO-SRRF offers the option of producing up to 123,000 tonnes of fresh water per day using multiple effect desalination (MED) of seawater in lieu of cooling towers. This process produces drinking water of better quality and at a lower cost than the majority of competitive supplies. GO provides water treatment and calcining, two reservoirs and a pumping station to inject water into the mains with a 100 metre head. A small proportion of water production is bottled and sold from the onsite water bottling and milk reconstitution plant which uses 50% recycled PET packaging. Household water consumption varies from 0 to 300 cubic metres per year, depending on the standard of living and the occupancy of each home. Typical NZ usage is 72.5 cubic metres per person per year. So GO-SRRF will support the total water requirements of 620,000 people in NZ.
• A plant will enable a region to plan its future infrastructure development to encourage further industrial development.
• A plant will provide up to 600 direct jobs and 2400 indirect jobs and a new base of industries important to the community.
• Shared regional and project company ownership facilitates a fair distribution of risk and reward to the required principal parties – refer to ‘Summary of Investment Opportunity’ to follow for the first regional and project company ownership in the Philippines.
• The structure is generic and percentages vary for different financial parameters and waste characteristics encountered in various regions and localities.
