Waste Gasification to Energy
Technology
Many waste to energy technologies have been evaluated for over a decade searching for the world’s best practice technology. To be the ‘best’, the selected technology needs to not only meet the best environmental performance criteria, but it also needs to be the best fit for the circumstances in which it will operate.
That means the optimum technical solution must also be capable of operating competitively with current waste disposal costs and be viable at a scale suited to local communities. Recovered Energy adopts an advanced Vertical Rotating Gasification technology with dozens of proven operational examples as the most appropriate technology to treat residual waste.
Gasification is typically referred to as an ‘Advanced Thermal Treatment’ (ATT) process. It is a generational evolution of more common combustion and incineration processes deployed widely to treat waste around the world. Gasification is generally accepted to offer significant benefits over other thermal processes used to convert waste to energy.
Gasification is a technology that converts carbon-containing materials, such as household waste, into a synthetic gas, generally called syngas. This syngas can be used to produce electricity and, in some circumstances, other products such as chemicals, fuels, and fertilisers.
Gasification does not involve combustion. Instead it uses little or no oxygen or air in a closed reactor to convert carbon-based materials directly into syngas. The controlled flow of air into the gasification reactor is insufficient to allow combustion to occur. Gasifiers are a modular design providing options for smaller and more scalable solutions to suit the waste needs of a community.
Emissions
Gasification is a chemical reaction that relies primarily on an exothermic reaction to maintain temperatures of between 800 – 950 ⁰ C. This ensures the almost total disassociation of the waste into syngas, resulting in extremely small amounts of residue, most of which can be utilised in other products. The gasification process breaks all carbon-containing materials down to the molecular level, so impurities can be easily controlled and removed.
The controlled air and high temperatures of the gasifier provides an environment unsuited to the production or reformation of unwanted emissions, making this technology more controllable and environmentally friendly than other alternative waste to energy technologies.
The high temperatures generated in this renewable energy process are supplemented by a sophisticated secondary system of best practice air and water treatment technologies. These systems will ensure the quality and integrity of the process and mitigate the risk of any and all possible discharge to the environment
