1. Introduction
The task for the students was to write about a topic that interested them, and to apply the learned knowledge and skills in connection with the course information literacy.
First step was to get an idea of what to write, therefore brainstorming was the adequate method. With the gained information an own mindmap was created.
Underneath, we can find both brainstorms, according to those brainstorms the topic has been chosen.
Then the research question was formulated: “What should we do with our plastic rubbish?” Furthemore three subquestions were formulated: “What is the current situation of plastic pollution?” “How can we recycle our plastic rubbish?” and “Which are the best possibilities to recycle plastic?”
The purpose of this research is to find out the damage that is caused by plastic rubbish and how to avoid it. Plastic rubbish is a global problem and affects us all. This research will be based on secondary research, so by existing literature.
The following chapters describe the findings of this report. Firstly it explains the search plan, made to lead the research. Secondly summaries of two main articles will be given and judged upon their professionalism due to the help of the CARS checklist. A literature review of one of the summarized reports will be given. The report will also contain a chapter about plagiarism and research ethics, which are very important to remember while writing a report. Finally the last chapter “discussion and conclusion” summarizes the findings of this report.

3. Summary of the article “Global declaration on plastic pollution”.
Nowadays people are in permanent contact with packages, bottles, toys and a lot more products consisting out of plastic. Most of the products end up as rubbish after the first hour they have been bought. About the question what is happening to the plastic once it is thrown away, hardly anyone is thinking. The answer is simple, the plastic is coming back to cause even more damage. The way it comes back hardly anyone can imagine. It is coming back through our food chain, to fulfill its task, causing diseases to animals and finally to human kind, which is last in the food chain.
For the last 60 years society has been using plastic in a wasteful way, with little concern in which ways this valuable, important and useful product can properly be disposed or recycled.
The results are catastrophic, between 60 to 80 % of marine debris are in direct connection with plastic products. In the 5 largest gyres of our oceans enormous quantities of plastic are concentrated, with enormous consequences for the animals that live in the ocean. The consequences are going further to the food chain and human health. (Catto Fellowship Program, 2012, p.2)
Plastic is not biodegradable, its decomposing into micro particles. Those tiny pieces are impossible to get out of the water, and the pollution degree is growing on a daily basis. The ocean plastic pollution can be identified as persistent, bioaccumulating and toxic substances. Due to chemical substances, as polychlorinated biphenol, PCBs, the pesticide DDT, several chronic health effects, as endocrine disruption, mutagenicity and carcinogenicity can be observed. (Catto Fellowship Program, 2012, p. 2)
The Term Paper on Plastic Pollution 2
Many individuals underestimate the amount of plastic we use each day. According to the article “Plastic Bags Wars”, “the world consumes 1 million plastic shopping bags every minute”. Plastic bags, along with many other types of plastics, have become a leading source of pollution worldwide (Doucette). Captain Charles Moore, founder of the Algalita foundation states that we use two million plastic ...
After summarizing the main facts of the pollution which can be traced to plastic rubbish, the next step is to find out what possibilities do we have to recycle the plastic.

4.Summary of the article „5 Stages of the Plastic Recycling Process”
Defintion
First of all it has to be clarified what plastic recycling means by definition: “Plastic recycling is the term given to the processing of waste plastic which turns old or scrap plastic in to a useable product which can then re-enter the manufacturing chain. In order for the plastic to be in a suitable format for re use in manufacturing environments such as by injection moulding companies the waste or scrap plastic, needs to go through several recycling processes”. (Daniel Marriott, 5 Stages of Plastic Recycling Process, 2011)
Classify Numbers
Before explaining the 5 stages of the plastic recycling process, the importance of the 7 numbers given to each plastic product while being produced, has to be explained. -Number 1 is used for “PETE”, which means Poly(ethylene terephthalate): Soda bottles, water bottles, vinegar bottles, medicine containers, backing for photography film. -Number 2 is used for “HDPE”, which means high-density Polyethylene: Containers for: laundry/dish detergent, fabric softeners, bleach, milk, shampoo, conditioner, motor oil. Newer bullet proof vests, various toys. -Number 3 is used for “V”, which means Poly(vinyl cloride): Pipes, shower curtains, meat wraps, cooking oil bottles, baby bottle nipples, shrink wrap, clear medical tubing, vinyl dashboards and seat covers, coffee containers. -Number 4 is used for “LDPE”, which means low-density Polyethylene: Wrapping films, grocery bags, sandwich bags. -Number 5 is used for “PP”, which means Polypropylene: Tupperware®, syrup bottles, yogurt tubs, diapers, outdoor carpet. -Number 6 is used for “PS”, which means Polystyrene: Coffee cups, disposable cutlery and cups (clear and colored), bakery shells, meat trays, “cheap” hubcaps, packing peanuts, styrofoam insulation. -Number 7 is used for “OTHER” Products labeled as “other” are made of any combination of 1-6 or another, less commonly used plastic and therefor very difficult to recycle. (Eco Reading, 2007)
The Term Paper on Plastic Recycling 3
Plastic recycling is the process of recovering scrap or waste plastic and reprocessing the material into useful products, sometimes completely different in form from their original state. For instance, this could mean melting down soft drink bottles and then casting them as plastic chairs and tables. Plastics are also recycled/reprocessed during the manufacturing process of plastic goods such as ...
5 Stages of Plastic recycling
Stage one – Sorting the plastic
In the first stage the plastic is collected by the recycling company and gets to the recycling plant. At the plant the plastic gets sorted out into specific types of plastic. In total 7 different numbers which are used to specify, which kind of plastic is maintained, can be identified: The problem in plastic recycling is that mixed recycled plastic cannot deliver good quality in manufacturing, therefore it is sometimes difficult or impossible to recycle the plastic to produce new plastic out of it. Recycling companies must therefore pay attention especially to sort out waste plastic.
Stage two – Washing Waste Plastic
Once the plastic has been sorted out, the washing process begins. Paper labels get removed, as adhesives and other impurities. Any third-party product on the plastic will lower the quality of the recycled plastic.
StageThree- Shredding the Plastic
In the third step the plastic is getting shredded through huge hoppers that funnel the clean scrap towards rotating metal teeth. The plastic is ripped in to small pellets, which are bagged and tested afterwards.
Stage Four – Identify and Classify the Plastic
After being bagged the plastic is getting tested chemically and labelled to its exact specification. Either the rGrade plastic can be used for manufacturing by adding a mix of virgin plastic, or it can be further recycled.
Stage Five – Extruding
In the last step the clean shredded plastic is going to be extruded in to form of pellets, so that it can be either used for manufacturing of for further recycling. (Daniel Marriott, 5 Stages of Plastic recycling process 2011)

5. Summary of the article “Startups make plastic rubbish to oil”.
This article is about the possibility to transform plastic rubbish into oil. Oil is one of the most used and important products and nowadays called the “black gold”. Oil relies on 10% of the world wide plastic production, so the main question should be. Why don’t we recycle it back to oil?
The possibility for this recycling process is given now. Pioneer companies as “Agilyx” and “Vadxx” developed a process, in which plastic can be transformed to oil again. The result is out of 5 kilogram plastic, 3,8 liter oil can be won.. Looking at the yearly production of 265 million tons of plastic, which moves right away to our garbage 1.5 billion barrels of oil, could be recycled. Only in Europe around 70 million tons of plastic rubbish are ending up on landfills. Looking at the actual landfills, which could be seen as giant oil pits.
The process is simple. In a first step the plastic gets assorted. In the second step the assorted plastic gets shredded and heated up to 400 degrees. The resulting synthetic gas cools down and is transformed into the end product, oil. According to “Agilyx” 75% of the oil, which is located in the plastic, can be recycled. Not forgetting the CO2 emission, which is 60 % lower as if we would simply burn the plastic. (Innovation: Startup makes plastic to oil, 2013)
Meanwhile this plastic recycling noise is spreading all over the world. In Germany for example the company “Nill Tech” situated in Mannheim has opened a factory, which is using the same procedure.(Company in Mannheim makes plastic to oil, 2013) 5.1 CARS checklist on “Startups make plastic rubbish to oil” and “Company in Mannheim makes plastic to oil”.

Furthermore the process is being explained, working as follows: The plastic gets assorted and shredded. The shredded plastic is going to be heated up by 400 degrees. Due to this heating up process, results synthetic gas. In a next step the synthetic gas cools down and results into oil, which can be used again. A last point is the CO2 emission, which is 60%, then if the plastic would simply be burned.
6. Plagiarism
First of all what is Plagiarism?
Definition found on “Dictionary.com”:
Plagiarism is an act or instance of using or closely imitating the language and thoughts of another author without authorization and the representation of that author’s work as one’s own, as by not crediting the original author. In short, plagiarism is all about stealing someone else’s work and lying about it afterwards.
During my research on how to recycle plastic rubbish, I tried to prevent plagiarism by summarizing the article into my own words. Furthermore every used source is given in APA style, at the end of the text. In short I used someone else’s knowledge, but summarized it into my own words.
7. Research ethics
According to the known information the used sources did not break any common research ethics. The author of this research used information, which were freely obtainable for everyone on the Internet. In order to prevent plagiarism and only use the sources for knowledge and information, no common research ethics was broken. It was not necessary to ask permission to use the mentioned sources.
8. Discussion and Conclusion
Then the research question was formulated: “What should we do with our plastic rubbish?” Furthemore three subquestions were formulated: “What is the current situation and why is it like that?” “How can we recycle our plastic rubbish?” and “Which are the best possibilities to recycle plastic?”
The main research question was “What should we do with our plastic rubbish?” The first sub question “What is the current situation of plastic pollution?”, was answered as follows: It was found out that the actual situation is catastrophic and is even getting worse. 60 to 80% of marine debris are in direct contact with plastic pollution, the 5 largest gyres of our oceans show an enormous concentration of plastic pollution. This high concentration of plastic pollution results into our food chain being affected and finally being the cause for several diseases for animals and humanity.
This fact lead to the next sub question, “How can we recycle our plastic rubbish?” The answer to this question has been found in the two other summarized articles. It has been found out that there are companies, which are specialized in plastic recycling, following a five step process. In this five step process the plastic gets sorted, washed, schredded, identified/classified and finally extruded. The end product is called rGrade plastic, which can either be manufactured by adding virgin plastic, or used for further recycling.
This further recycling leads us to a second effective possibility of plastic recycling. Transforming plastic into oil, which is one of the most wanted resources nowadays. Pioneer companies made it possible to develop a process, where 3,8 liter oil can be produced out of 5 kilogram of plastic. This process works as follows: The plastic gets assorted and shredded. The shredded plastic is going to be heated up by 400 degrees. Due to this heating up process, results synthetic gas. In a next step the synthetic gas cools down and results into oil, which can be used again. An important aspect of this process is also the CO2 emission. It uses 60% less CO2 emission, then if the plastic would simply be burned.
The last sub question “Which are the best possibilities to recycle plastic”, has also been answered. We can say that the “five step recycling process” is the basic, which should be consequently applied all over the world. The possibility to gain oil out of used plastic again, should be seen as a continuation on the “five step recycling process”. To answer the main question “What should we do with our plastic rubbish?” It can be said that the answer is recycling as much as possible. Recycling due to innovative techniques, which can be further developed and ameliorated. The reason humanity has to focus on plastic recycling is not only because of the fact humanity is polluting his earth, which is our source of life. Furthermore the wasteful use of resources will create economical crises, prices of essential products will rise into immeasurable circumstances and make life on earth much harder. All people do need to start thinking long-term and more important in a sustainable way!
