I need some assistance with these assignment. gasification as thermal conversion technology Thank you in advance for the help! The gas parameters and the nature of the product include the amount of oxygen in the air stream that gets into the reactor and the temperature, which for solid carbonaceous fuel should be between 7500 F to 8500 F. At the final stage, the gas composition depends on how much oxygen and steam are in the reactors and the duration of the entire reaction. Gasification maximizes renewable energy recovery. It facilitates converting renewable energy and non-fossil fuel into substitute gases that can be injected into the Gas grid of the City’s planned trigeneration network. By creating a “natural” gas from waste, gasification reduces the number of fossil fuels required to power up the City. this significantly limits greenhouse gases released into the atmosphere. More importantly, it provides for storing a non-intermittent renewable energy source, unlike solar and wind power, since its supply cannot fall.

Material energy resources recovered from landfills minimize the amount of waste disposed of through this method by eliminating approximately 90% of dumps’ content. Therefore, it almost wholly serves the purposes of reducing the amount of waste in landfills, which is a significant part of the reason it was recommended in the master plan. Gasification can contribute to the increase of reliability because of providing an alternative energy source that is perpetual, unlike fossil fuels with limited supply. Also, residual waste from landfills is diverted to a more profitable and less pollutant purpose of generating energy.

Mechanical and biological treatment

The Mechanical and biological treatment is a combination of two processes using modern technology to separate the organic from inorganic waste to be further refined separately. In this case, the trash can range from domestic waste, sludge, sewerage, crops, and livestock manure. Since 2007, this has been the primary method of waste management in Sydney, but it has been proven to be less than useful since over half the components have to be landfilled. Organic waste is separated from the recoverable recyclables through the mechanical process such as plastic or glass (City of Sydney, 2013). The biological process, on the other hand, degrades the waste by composting using microorganisms in an anaerobic environment to digest the organic material.
