Biology coursework: Recycling Introduction My aim is to find out about recycling in my area by doing a survey. I need to find out about the different points of view from different people about recycling and the reasons for why they do or don't recycle. I also need to find out the main material that is recycled and how many times people recycle in a month. These would give me an idea about recycling and its impact on the society. To accomplish my aim I will hand out my questionnaire which will consist of five simple questions to forty houses in my area. I will give to three houses from every street and then I will collect the questionnaire after four days. After collecting it I will then record the results in tables and charts. Thereafter I will make a conclusion of my results and will then compare the conclusion with the information on the websites. Questionnaire Below is the questionnaire that I used for my survey: Do you recycle? Yes ( ) No ( ) How many times do you recycle in a month? 0( ) 1( ) 2( ) 3( ) 4( ) 5+( ) What makes you recycle? Less Landfills ( ) Save environment ( ) Law ( ) ...read more.


It is also used for junk mail and brouchers. Also paper is easy to recycle which means that more people recycle it. Plastic is recycled more probably because it is used for many things like bottles, containers, wrappings etc but not all plastics can be recycled which means that the percentage of recycled plastic would be lower if I were to ask more people. Glass and cardboard are recycled very less. This is probably because not many things are made from theses two materials. Very few household items are made of glass, e.g. Jam jars or some drink bottles. Other than that mostly everything is made from plastic. Also cardboard is used very rarely in homes. It is only probably used for boxes. Metal is hardly recycled because many metals items are huge and so many people cannot be bothered to take them to recycling areas. Some metals like cans are recycled a lot by some people as they drink a lot of fizzy drinks or alcohol but I think I would need to ask more people or ask from different places in my area to get proper results. The information given on the website agrees with my results mostly. It shows that paper and card is recycled the most after compost but I never included composting in my survey so my results cannot agree with that. ...read more.


Either a big hole is dug to bury the rubbish or a mining pit, natural occurring valley canyons are filled with rubbish. The rubbish is put in layers. When ones rubbish is disposed it is crushed by a bulldozer before the next layer is disposed and layed over it. At the end the rubbish is covered by earth to make sure less pollution is made and also so that the countryside does not look dirty. The good thing about landfill is that it is cheap and easy to do; the rubbish does not have to be sorted out. The disadvantage is that it produces a lot of gases including poisonous gases from fridges which can harm the environment. Incineration Incineration is a method used to handle rubbish. Waste is burnt in high temperatures and the waste heat from the burning can be used to generate electricity. The temperature inside the incineration can reach up to 850 degrees Celsius. This high temperature is needed to ensure that the organic waste is broken down properly. The advantage is that it can be used to produce electricity and by burning the rubbish it means that 95% less space is taken to bury the rubbish. The disadvantage is that the ash might be very toxic and so it has to be handled with care e.g. taking to a special landfill site that handles with toxic materials. It still produces a lot of pollution even if the gases given out by the factory are filtered. ...read more.

Here's what a teacher thought of this essay

3 star(s)

A very good effort. The graphs and charts of the results are very effective in clearly showing the trends of the results.

Some of the results were still unclear in the analysis section due to limitations of the questionnaire, such as why did some people chose not recycle? Limitations like this can be included in the report and explain how you would improve this in future experiments.
The material at the end on recycle, incineration and landfill are very informative but this information would usually be included at the start of the report, not after the conclusion.

Be careful to maintain a formal writing style throughout the report.

    Salt has the effect of lowering the amount of free water molecules present therefore hindering the growth of bacteria as moisture is vital for their survival [http://www.cfsan.fda.gov/~dms/qa-sto5.html]. It was thought that salt would have a limited effect because the antibacterial properties, though evident, were not strong, and this was proved to be true.
