Title: Waste Incineration at Eastern Creek

in New South Wales

-Describe the facility.
— Where is it located and who are the main “user groups” of the facility?
— What types of waste are accepted, and how do they manage them?
— What systems are in place to maximise diversion from landfill?

At the Eastern Creek Incineration Plant 1 in New South Wales, wastes arrive in refuse skips and Lorries. The waste is dumped at a huge silo from the Lorries into the site using huge cranes. This procedure helps in quickening the process of drying the wastes as well as mixing them up evenly. Mainly, the wastes brought to this site are those collected by the Municipal around the city. Due to high workload, the facility operates all through the week. In the huge mass of waste, the facility places huge priority on plastics, aluminium and textiles. First, aluminium and steel are removed from the wastes using huge magnets. However, these processes may disrupt daily activities around the neighbourhood owing to the huge clouds of dust that arise during the offloading of wastes. On the other hand, the facility contributes significantly towards reducing wastes that could otherwise be dumped at designated landfills. The huge capacity of the Combined Heat and Power (CHP) incinerator in the facility contributes to production of renewable of energy. Primarily, as more options of recycling become available, renewable energy can be used in production of electricity and heat. Moreover, recycling of plastics and textiles minimizes emission of greenhouse gases by 2 tonnes every hour. In the contemporary world, economic and environmental concerns have led to the introduction of incineration of waste as a means of diversion from landfills (Christensen 2011, P.23).


How can you determine if wastes that your company generates are acceptable for
treatment at the facility?
— Do they comply with the provisions of any legislation, EXPLAIN
if they do not, how could
they comply?

The Eastern Creek Incineration Plant 1 in New South Wales can be considered to be an efficient system for energy recovery. Despite its hourly production of 8 tonnes of GHGs, the facility serves the nation by recycling all the Municipal wastes. Creation of larger capacity in the facility would ultimately contribute to less dumping of renewable wastes in the landfills. The nation produces huge amounts of wastes and it is unlikely that the facility could run out of materials. Focusing on the advantages of renewable energy, the nation needs to focus on enforcing production of alternative energy sources for both domestic and industrial functions. Since the facility receives even the degradable wastes, a composting facility needs to be installed. Among the five year strategies of waste management in South Australia, we can discuss the five primary objectives for the same. First, the public needs to be informed and encouraged to observe sustainable behaviors. In this view, people can recycle resources in the most suitable approach. Secondly, the waste disposal to the landfills should be minimized. Here, the legislations state that waste materials should be put to more positive consumptions. Thirdly, effective waste management systems should be implemented. The Zero Waste strategy aims at establishing, maintaining and increasing the ability of waste management systems as well the reprocessing industries. Fourth, effective policy instruments that enforce the application of alternative energy technologies would significantly lead to reuse, reduction, avoidance and recycling of renewable wastes. Lastly, the stakeholders in production of renewable energy need to maintain a single target and goals towards successful recycling of wastes (Jakab 2011, P.43).


In your view is the facility appropriate for the types of waste that are sent there for
treatment/disposal? Describe why you have determined this.
— What charges are applied for the different wastes etc?

Landfill and incinerators cannot be compared without considering the aspects of pollution in both systems. Putting the facts of Carbon Dioxide emission from the Eastern Creek Incineration Plant 1 in New South Wales into context, the facility is responsible for nearly 560 tonnes of Carbon Dioxide produced every hour. Therefore, this facility could be ranked among the major producers of Carbon Dioxide since it contributes to 3% of the total Carbon Dioxide emissions of the city. The Green Houses Gases constitute of Nitrogen Oxide and Carbon Dioxide. Since N2O and CO2 have longer durations, it could be concluded that incinerators have greater negative effects to the environment as compared to landfill emissions. However, at the Eastern Creek Incineration Plant 1, Carbon is reclaimed so as to equalize production of energy. Therefore, the Eastern Creek Incineration facility serves a defined purpose in environmental conservation and energy production. At the facility, different materials are treated differently. For instance, aluminium, steel and wood are recycled and not incinerated. Also, plastics and glass are grouped by weight and treated differently (Rogoff & Screve 2011, p.44).


What innovative steps are taken to minimise the impact of the operations on to the
environment and any neighbours?
— What recommendations would you make to your manager regarding the facility and
whether your company should continue to utilise it?

As we discuss on the incinerator, we need to consider the different carbon dioxide cycles in garden wastes and fossil fuels like those found in plastics. Primarily, Carbon that is drawn from the environment tends to have short cycles. Therefore, these forms of carbon cannot be accredited for the increasing levels of atmospheric carbon dioxide. The incinerator produces short cycle carbon dioxide that amount to 7 tonnes per hour. Consideration of the N2O would increase the volume of produced greenhouse gases to 8 tones every hour. The core reason for recycling is that production of recycled materials demands less energy as compared the energy required for producing materials from raw materials. Municipal waste differs from the hazardous industrial waste in that the prior occurs in its solid nature. In addition, since the solid wastes are heterogeneous, the facility requires unique and special incinerators for each material. There are various technological advances in renewable energy that can be used in this situation. These technologies include fluidized bed, mass burning and refuse or waste derived fuel (RDF, WDF). Also, technologies like gasification and pyrolysis can be applied. In the process of gasification, wastes are heated in steam, air or oxygen and thereby convert to gas. Varying the components of steam, air or oxygen could result in formation of carbon dioxide, hydrogen, carbon monoxide, methane and water vapor. These gases can be channeled towards gas powered turbines and engines that ultimately lead to the production of synfuels otherwise known as liquid fuels. The ash residue that constitutes nearly 25% of the original waste weight may be landfilled or reused in other functions. In large scale gasification, multiple hearth rotary kiln vertical fixed bed, fluidized bed, and horizontal fixed designs can be applied. On the other hand, pyrolysis involves processing waste in thermal heat in the absolute absence of oxygen. At 500-800 °C temperatures, organic wastes are converted into liquid, gas and char-fraction. In some instances, pyrolysis and gasification can be combined in order to produce high quality synthesis gas (Rand, Haukohl & Marxen 2000, p.39).
