Construction of Thermal Waste Treatment Plant
According to Hundertwasser, Friedensreich (34), the major idea of constructing the plant was to devise a dynamic waste plan ranging from opinion forming and providing information on how to avoid the creation of wastes through recycling and optimizing waste separation. The other concern for the construction of the plant was to emphasize on the reduction of waste gases and problematic residues, taking into account health, legal, social, and community needs. Hazardous materials present in slag and ash can be avoided if such materials are not involved in the production of goods. Excessive residual waste is a waste of resources and non-hazardous waste materials can also become problematic in terms of volume (Hundertwasser, Friedensreich. Hundertwasser, 45). Some kinds of wastes can never be reutilized; like the multi-component products. These are products which have severally been recycled or substances that are severely contaminated. However, such wastes are not necessarily wasted since the energy content in them can be used to generate electricity and district heating through incineration.
The construction of the plant also has some additional beneficial side effect such as reducing the volume of waste. In the plant, the storage depot normally receives daily deliveries of 250 waste vehicles and holding reserves for around three days. The plant comprised of two boilers that produced steam from waste materials and a counter-pressure turbine was also attached to the boilers that helped in the generation of electricity. The plant also had four heat exchangers for supplying the heat and a gas purification system (Hundertwasser, Friedensreich. Hundertwasser, 34). To destroy pollutants existing in the shut-down and start-up phases, there is need to impose a condition that requires heating of a flu gas to a temperature of around 850o C for about two seconds. The process of incineration produces a high pressured steam, which drives a coupled generator and the turbine to satisfy its own needs of electricity. Excess electricity generated is then fed in the national grid, which can be used during downtime periods to power the plant. The return water and steam from the heating pipe are fed through condensers thus enabling the transfer of energy from steam to return water. Ash and slag are taken separately and then mixed with cement and water. The slag cement can be put into use as a construction material and is chemically active and inert. The filter cakes containing heavy metals are then stored in a salt-mine in Germany (Hundertwasser, Friedensreich. Hundertwasser, 43).
In 1969, the city council of Vienna entrusted Heizbetriebe with operational objectives of building up, operating and maintaining metropolitan district heating supply and proper disposal of solid wastes. This was to be made possible by the operation of Spittelau thermal waste treatment plant, which was by then under construction. The ongoing expansion programme created an interconnected heating network that was fed by ten individual plants with a capacity of over 2,500 MW. The plant had a pipeline of around 900 km in length; that being the largest in Europe. The plant supplied heating energy for water heating purposes to approximately 4,400 industrial consumers and over 200,000 dwellings (Restany, Pierre, and Friedensreich, 24). The purpose for constructing the Spittelau district plant was to avail heat for the new General hospital that was situated some few kilometers away. The plant had a rated capacity of around 460 MW, thereby making it become the second largest supplier of the district heating network. The thermal waste treatment plant, which was located around the heating generating plant, had a capacity of around 350,000 tons of weight annually. In order to comply with the continuous changing of the state-of-the-art cleaning technology of the flue gas, a flu gas scrubbing system was equipped on the thermal waste treatment plant as well as dioxin destruction facility and an ultramodern SCR-DeNOX (Restany, Pierre, and Friedensreich, 43).
The previously functional, sober structure was changed into a unique work art, which was successful and formed a harmonious connection between ecology, art, and technology. It also contributed to the reduction of pollution of the urban environment. The municipal solid wastes from Viennese, that is, non-hazardous commercial and domestic wastes of similar composition were normally delivered to the thermal waste treatment plant every week from Monday to Friday. About 250 delivery vehicles were received daily and could pass over a weighing bridge to determine the weight of the waste and then emptying the loads into the waste bunker. The thermal waste treatment plant is composed of two incineration lines, each having a flu gas treatment plant with dioxin destruction facility and SCR-DeNox serving both lines (Restany, Pierre, and Friedensreich, 27). The plant also had a flu gas scrubbing system that produced a treatment plant for waste water. The plant functioned by letting wastes pass through the hydraulic ram feeder and the furnace feed chute and then moves down to the bunker and firing grate located at the end of the furnace.
The incineration process produces an 850oC flu gas, which provides heat to the boiler of the waste heat, which results in the production of approximately 90 tones of saturated steam per hour. For power to be generated, the steam is reduced to 4.5 bar back in the pressure turbine after which it is moved to the returning water through condensation in the next heat exchanger bank. The incombustible components reaching the end of the firing grate are cooled down by dumping them in a water-filled slag discharger (Restany, Pierre, and Friedensreich, 56). The cooled gas is then moved to the slag bunker through the removal of ferrous scrap and overhead electromagnets. The use of a computerized firing control system makes sure that there is optimum incineration in the grate, and hence a maximum flue gas and slag burnout (Hundertwasser, Friedensreich, 78). When the thermal waste treatment plant was commissioned in 1971, it had a very effective electrostatic precipitator and this was augmented a flu gas scrubber in 1986. The construction of the plant and production of the flue gas made Spittelau become an international leader in emission reduction and flue gas cleaning for the thermal waste treatment plants.
The district heating plant generated approximately 36,400 MWh of electricity and approximately 263,200 m3 of waste deliveries in one year. The plant also produced electricity that served 4,200 public buildings and 190,000 homes and also supplied heat to Vienna’s largest hospital. Continuous innovations and checks in the gas purification plants set high standards for the emission of any pollutant. Among other plants that offered similar services of gas emission reduction included the DeNOx plant, which reduced emission of dioxin and nitrogen oxides. All emissions have an average threshold value of around 30% and the waste incineration plant was only allowed to operate when the entire purification process of flue gas was properly functioning.
The constructed waste incineration plant formed part of the city’s plan for waste management, with a fundamental aim of preventing the creation of any form of waste. For residual wastes, the plant represented the realization of a plan conforming to the latest standards of waste management systems. The approach used in the construction of the city’s waste management system can be used or applied in other situation or construction in the modern world. The plant was designed in a very unique manner and presentation and this has made the plant become a tourist attraction site even after the Viennese artist called Friedensreich Hundertwasser died in 2000. According to Restany, Pierre, and Friedensreich (23), the plant has also attracted the construction of several other social sites and architectonic constructions in the whole area.
In the 2001, there was a partnership established between Maishima Osak plant and the waste incineration plant, whose constructions were also designed by the artist Friedensreich Hundertwasser. The partnership between the two plants was established with the primary purpose of exchanging information on the best ways of handling wastes and recycling used products. The exchange of information was majorly based on operational management (waste management, energy use), operational experience with different technologies, dealing with the public, and passing on Hundertwasser’s visions and ideas to posteriority. However, in the long run, the exchange of information will advantage both the plants as well as have positive impacts on political relations between the two nations (Restany, Pierre, and Friedensreich, 89).
Signing of the partnership between the two plants prompted mutual visits and teams of experts have been able to exchange experiences in the operational management field and the social practices of the two plants (Restany, Pierre, and Friedensreich, 23). The partnership also emphasized the importance of designing buildings as designed by artist Hundertwasser and also discussed the strategies they could use to get acceptance from the public in relation to how they serve the public in controlling wastes. Another team of experts also took a close look at the management and the operation of the existing plants and then used the findings to adopt new methods and strategies that would be viable in waste management in any kind of environment.
If the plant was to be constructed today, the most important aspect is to learn how to exchange information with the public to ensure that what is provided is within the interest of the public. There is need to first collect full information from the public before starting any project (Restany, Pierre, and Friedensreich, 43). In addition to that, there is also the need to carry out research and come up with findings that would ensure that the constructors share any relevant information that would be very significant in implementing their operations and objectives. This was witnessed by Japanese tourists and constructors who visited the plant at Spittelau just a few months before constructing their own plant. Exchange of information will not only make the constructors put up a very strong plant but also make their nations become active in the field of urban waste management and environmental protection. The plants should also have been constructed based on the existing technology and market strategies, which enable the industry raise the technical standards to reach the best available technology and at the same time promote good public relations for adequate environmental protection. In summary, the plant should have been constructed to match the modern state of infrastructure and technology.

Rene Descartes Meditation On First Philosophy: The Existence of Human Mind
We live in an era where everyone is trying to establish the validity of factual nature. Rene Descartes was a philosopher who lived between 1596 to 1650. Descartes gave mediations on various factors, including the existence of God and the existence of the human mind. In 1641, Descartes gave meditations on the first philosophy. He gave his views on knowledge, the existence of the mind and its relation to the body, how we perceive ideas, and the fact that God exists. He gave all these meditations in an attempt to bring out some mathematical truths on the above concepts. “I am, I exist, is necessarily true each time that I pronounce it, or that I mentally conceive it” (Descartes, 13). This is one of his meditations on the existence of the human mind and it indeed exists.
First, arguing about the ability to think, provided that one can have thoughts, then it implies that the human mind exists. Descartes argues that where he is dreaming or not, there are thoughts as a result of the mind. The mind is nonphysical, non-spatial but can influence daily activities and matter. The mind is different from the brain since the brain can exist, but to be functional, there must be the human mind.
The nature of the mind is to think, which proves its existence. In agreement to Descartes’s argument that if something does not think then he has no mind. Indeed, all thoughts are controlled by the mind. Since the nature of the mind is to think then human beings could not make rational decisions if the human mind did not exist. The mind exists even when we are asleep, we can still think through our dreams. Through the mode of thinking, there are ideas. Ideas can be both factual and non-factual but it is because of the existence of the mind that human beings have to come up with different ideas.
The existence of the human mind can be proven by the ability to make rational and irrational decisions. Descartes asserts that the mind controls the different modes of thinking. At some point, one has to decide on certain events. To make right or wrong decision, the mind has to be used. Without the mind, a lot of things would be in inexistence. There would be no technological innovations due to the lack of the ability to think. Since the human mind exists, it is easy for people to judge events, correct their mistakes, and help others. It is through the mind that the brain is able to receive information from different parts of the body, process it and give the correct output information. The mind controls the brain since once information is received, since the mind can think, it then dictates what to be done next.
Lastly, Descartes did a meditation that there are different thoughts that the mind processes. There are both judgments and emotions, which results from the mind’s ability to think. Descartes says “Other thoughts have various additional forms: thus when I will, or am afraid, or affirm, or deny, there is always a particular thing which I take as the object of my thought, but my thought includes something more than the likeness of that thing.” (Cottingham, 24). It is through the mind’s ability to think that one becomes afraid or gains the courage to do something. Humans can exist without the body but cannot exist without thought. For instance, one can lose several body parts but still can think about various subjects.
Conclusively, it is true that the mind exists and controls human activities. Without the mind, humans can hardly exist or cope up with daily challenges. Human beings, including Descartes, are the same people who doubt everything, understands different things, and affirm what is true or not. The thought is what makes doubt the existence of the human mind.

Olaudah Equiano Slave Narrative
In the American literature canon, Olaudah Equiano’s narratives were distinctive as they held as they were particularly important and influential in the 18th century (Richards & Sandra,70). The narratives by Olaudah are mostly based on his experience as an enslaved man who was able to buy his freedom. The experiences date to when he was sold to a Royal officer at the age of 11 years from the kingdom of Benin until he rose to be a prominent figure spearheading the campaigns to abolish the slave trade (Equiano).
The most common form of slavery that was known to Americans was the slavery in which an individual was considered as someone’s legal property, the chattel slavery. This form of slavery allowed people to be bought, sold or even owned forever and was supported by many powers in the 18th century. Olaudah’s narrative writings and songs that developed from the period were aimed at opposing the pro-slavery propaganda through the development of his experiences and other horrific treatment that the African slaves were subjected to giving a rather unique perspective into the American chattel slavery methods (Richards & Sandra,70). Most of these narratives were guided and influenced by the thoughts of abolitionists.
The interesting narrative of the life of Olaudah Equiano was first published in the 1700s in London represented various styles such as the slavery, travel and spiritual narratives that are considered to be integral and important parts of the African American literature (Richards & Sandra,70). This essay is written to analyses and find patterns that are developed in telling collection of stories and examine the structural elements of the writings that are used in telling the stories. Mentioning Equiano’s narrative, the essays seek to analyze the musical genres such Spiritual, gospel and work songs with highlights of traditions, subversive language, governance and identity that were developed from the Narrative Life of Olaudah Equiano.
Spiritual genre is usually the type of American folk music that was developed by Africans narrating the suffering of slaves as they articulate their longing for freedom and passion of religion during and after the era of slavery (Ammerman & Tatom). The slave narratives helped in the creation of music that developed hope and a sense of belonging. These songs often covered their traditions as they remembered their homeland in instances like the abduction of Equiano from his African home and be sold to a royal solder who owned him and controlled his life hence lacking his identity. The narrative by Equiano develops a spirituality concept in that he often attributes and regard the good things to him as the works of divine providence as shows whereby he acknowledges that his sufferings were great but comparing them with his fellow countrymen, he regarded himself as a favorite of the heavens. The spiritual nature of songs developed from this narrative was well understood in the context of the experiences the African American slaves had experienced. These songs are often adapted by the audience over a period of time as they are understood and collectively composed (Ammerman & Tatom). As the narrative life of Equiano tries to depict the horrors of slave trade is the same as songs that are created from the slave narratives try to articulate the suffering and longing for freedom of the slaves just like Equiano was able to be a freeman finally despite being prosecuted and discriminated because of his color(Equiano). The spiritual songs mostly used subverting languages with double meanings as some surface meaning may be a cry and a longing for a place in heaven that might in the real sense be a cry for freedom and desire to escape slavery that Equiano used as a form of language in his writing.
Gospel genre is a type of music that was created by slaves’ narratives that tend to tell their stories articulating their longing (Will & Lawrence). These kinds of songs developed can be traced to the early 17th century as the content of the songs normally tend to emphasize on messages of God, salvation, the kingdom of God and development of other biblical instances. The songs developed from slaves’ narratives tend to praise the mighty God and acknowledge their privileges to a mighty God. As from the introduction, Equiano introduces self as a pious Christian, whose conversion religious meant some form of freedom that would be referred to the manumission from slavery. This kind of manumission represents a certain form of salvation. Referring to biblical texts shows a front piece in governance through the life story of Equiano. With the tradition of a protestant Christian Equiano in his narratives tells his story as a testimony of Gods actions in his life. In order to be accepted by his American and British audience, Equiano uses religion that develops gospel genre songs to maneuver and be accepted as a credible writer although forces of acculturation take over to dismiss the religious perspective of Equiano (Equiano). Equiano uses religion for his readers to accept their racial identity and also be racially aware and critique the society with religion piety whereby he quotes on the authority of Moses and the Egyptians. The biblical texts help to show governance and develop a sense of identity for the audiences. The African slaves included the biblical contexts in songs to express their anger of bondage (Will & Lawrence).
Work songs around the world are traditional songs developed by labourers for many different occupations such as the agricultural picking of cotton or even industrial building of roads (Nagy &Gregory, 14). These songs helped to keep work moving slowly as their purpose was to increase coordination and reduce boredom at work. These were mostly developed after emancipation whereby most Africans felt that the spirituals should be left behind with slavery. Some of these songs were developed in a creative for in that they showed Africans working in restriction some form of light (Nagy &Gregory, 19). From the narrative by Equiano show that from their abduction the adults were out to work, Work songs would develop from the sails to make the work flow smoothly as Robert King had tasked Equiano to work on the ships so as to enable him to buy his freedom (Equiano). Equally selling tumblers and fruits would help in the generation of the work songs genre. Even after freedom, Equiano continued to work at sea with Dr Charles Irving. Even though he never worked at the plantations several events made him question faith as his friend was kidnapped and taken to work at the plantation where he worked at until his death. He quotes prophet Micah on what makes any event important. The working recorded by Equiano was to develop the economy, social and educational conditions that were poor in Africa (Equiano).
Equiano refers to himself as almost an English man after he was signed to be a freeman and no longer a property of another person, whereby he could make his own decisions without control (Mottolese & William, 160). The poetry developed in this narrative shows how Equiano regard the good things to him as the works of divine providence as shows whereby he acknowledges that his sufferings were great but comparing them with his fellow countrymen, he regarded himself as a favorite of the heavens
Non-fictional prose of the narrative is presented as the literature work of Equiano’s in his book were based on facts and real-life events that happened to him. These events were developed in the narrative as his journey from birth as a free man through which he was sold as a slave to the moment he bought his freedom and started to fight for the abolition of slave trade as an abolitionist. The conclusion of his introduction, Equiano noted that he was not foolish to expect literary reputation but rather he wanted his book to offer satisfaction to his numerous friends under whose request the book was written with the promotion of humanity interests that would be fully attained at the end. The prose in this book developed from the instance where Equiano explains how he was abducted from Africa, giving details of his abduction and its consequences (Equiano).
The genre of prose is developed in the writings of this interesting narrative as the work could be described with the use of neoclassic prose that was developed primarily as the age of reason (Khosa, Maurice & Kalitanyi). It was hard for the author to project and report his experience as a slave to the audience that did not consider him or other slaves as part of their society but rather an alien thus the encompassing of drama and the subversive language to attract the attention of the reader from the period in which he describes his homeland capturing the attention of the whites(Mottolese & William, 160). The age of reason saw his writing and the narrative as an integral part as it played a big role in the abolition of slave trade. With part of the narrative written as an enslaved African giving the horrors of the slave trade first-hand the neoclassical prose was intended to reach and influence most of the abolitionists (Khosa, Maurice & Kalitanyi).
“Accordingly, he signed the manumission that day; so that, before night, I who had been a slave in the morning, trembling at the will of another, became [sic] my own master, and completely free. I thought this was the happiest day I had ever experienced…” (Equiano) this statement meant that the author on purchase of his freedom he was for once a freeman which many other slaves had dreamt of, thus an essential part of the narrative towards self-identity and awareness. This accomplishment saw him govern himself as a man and no longer a property although the consequences of being still subjected to discrimination and persecution as a black man he was able to make decisions and control his life. The narrative depicts the early life of Equiano as an African slave who had no identity but despite all that he perseveres to shape one (Wiley, Michael, 165).
Even though the author identified himself with British culture, religion and manners he is aware of his African roots whereby despite the view of the Britons that African were backwards he argued that they were not any much different as they only lacked information (Equiano). The life of Olaudah Equiano develops all genres of literature with spiritual and gospels and works songs being derived from quotes whereby he referred to God and attribute his life to divine intervention and experiences of the author as a slave and a freeman. The autobiography written by a former slave shows the on matters of governance and how the Africans slaves were regarded as legal property (Wiley &Michael,165). They lacked identity until the purchase of their freedom whereby they are able to make decisions on their own despite discrimination and persecution as black people. At the end of the narrative, the author after showing the horrors and other terrific episodes that befall the African slaves, he made clear that abolition of the slave trade was his intent. Equiano uses subversive language to undermine the normalization of slave trade and ownership of people as property through the use of emotions and his experiences and horrors as a slave to influence the rise of abolitionists undermining slavery and advocating for the abolition of slave trade.
