DEODORISING TRASH COVER

Abstract

The study of deodorizing trash cover by using charcoal is scientific project of Mathayomsuksa 4 at Srisawatwittayakarn School , 2010. The objective of the study focus on using charcoal to solve the problem of unpleasant smell in the trash. The study compared three trashes which were used different types of charcoal. Data collection was carried out by experiment,

analysis and data were processed with descriptive statistic; frequencies, means and percentages. The result revealed that: using small pieces of charcoal for making the trash lid in the most effective on stopping unpleasant smell.

For Further study in future development, the study should investigate other kinds of materials used in the experiments and various methods of the experiment should be used.

Significance

Nowadays garbage are scattered all over the area such as public park, school, street. It usually has problem of bad smell in the trash that create a nuisance to people.

This study hoped to help solving this problem by finding a new materials to make garbage cover ,and we found that charcoal has ability to drain smell ,It also has a low cost and it is easy to find, we made the trash lid by using charcoal and the materials helps solving the problem effectively.

Objective of the study

- Decrease garbage smell by bin lid.

- To learn surface area of charcoal affect to smell draining.

- To compare kind of charcoals which is the best smell draining.

Hypothesis

If surface area of charcoal does not affect to smell draining so every charcoal garbage smell ability are same.

If surface area of charcoal affect to smell draining so charcoals are the best to drain garbage smell.

If surface area of charcoal affect to smell draining so charcoal dusts are the best to drain garbage smell.

If surface area of charcoal affect to smell draining so pieces of charcoal are the best to drain garbage smell.

Related variable

Variables – deodorize trash cover.

Dependent variable – ability to drain garbage smell of three kind of charcoal.

Control variable – quantity of charcoal, kind of charcoal, trash cover size, bin size

Scope of the study

To compare drain garbage smell ability of charcoal sticks, pieces of charcoal and charcoal powders. Tested with same garbage. Experiments was conducted at Srisawatwittakarn school between August 13 – 16 2010. There were ten people to smell test.

Chapter 1Importance

Nowadays charcoals are material that help people many ways for example use in household (such as absorb humidity, to make fire, decrease disease), use in industry (such as product chemical, wastewater treatment), in agriculture (such as improve ground, maintain productivity, improve quality of water). Charcoals are very useful than we known but people ignore charcoal, do not known about useful of charcoal. Authors made deodorizing trash cover that use charcoal to absorb bad smell to see the importance of charcoal and useful of charcoal to use in other ways.

Chapter 2How to Invent the trash cover

Equipment Bamboo strips 4 lines Grill 3 items Needle and thread set 1 set Net 3 pieces Piece of cloth 1 piece White cloth 1 piece Charcoal 300 grams Charcoal dust 300 grams Pieces of charcoal 300 grams

How to Invent the trash cover

1.Weave the bamboo strips

2.Sewing bamboo strips to trash cover and sewing a cloth with cover.

3.Put charcoals on grill and sewing grill suture net. Cover charcoal with white cloth and hang it measure top of trash cover and the grill.

4.Do the same that have three covers. One put charcoal sticks. One put charcoal powder. One put

piece of charcoal.

2.Weight vegetable the same.

3.Divide vegetable into 3 black bags same type and weight.

4.Mix all ingredients.

5.Close bags for 24 hours.

How to do

How to experiment

10 volunteer take turns smelling the trash.

Record in a record of smell level.

Smelling the trash again in next day for accuracy.

Data collecting in two days and average.

Chapter 4The finding of the study

The study found that the levels of smell in each garbage which was covered by different kinds of lids various according to the material we used. (the charcoal in the first bin, the small piece charcoal in the second bin, and the dust of charcoal in the third bin) The results that we found are as follow;

The finding of the study

On the first day, there is no difference of the level of smell among the three bins. The smell in three bins reaches the highest point.

On the second day, the smell of first and second bin slightly decreased while the smell of third is still highest point.

On the third day, the level of smell in the first bin is higher than in the second bin. And the smell of the third is still the highest level as in the first two days and there is no change in the second bon which was used small piece of charcoal.

The finding of the study

According to the study, there is the lowest level of smell in the second trash when compared with the first and the third. We can conclude that the surface area of the charcoal affect on deodorizing the unpleasant smell of the rubbish.

And pieces of charcoal in garbage lid of second bin can deodorize the bad smell better than the bigger pieces in first trash cover. Comparing with the third trash which used the charcoal dust, it is better to use the pieces of charcoal (like the second bin) because there are small holes in the pieces of charcoal. These help to deodorize or absorb smell more effectively than the charcoal dust.

The advantages of the study

The study helps to decrease the unpleasant smell from the trashes.

The study helps to increase the utilization of charcoal.
