This document reports on a survey of daily solid waste disposal over 32 days. The average daily waste generated per person was found to be 443 grams. Food waste made up the largest portion at 75% of the total waste. Paper/wooden, aluminum cans, and plastics each accounted for 7-10% of the waste. The results suggest separating waste types for more effective recycling and management to reduce environmental impacts.

I. Introduction
Solid wastes are the materials or substances which are discarded or
disposed by people after usage. Solid Wastes can come from many sources such
as: home, school, hospitals, industries, farms and other sources.
Since the industrial revolution, Solid wastes have been a major
environmental issue in everywhere. The disposal of solid waste is a problem that
continues to grow with the growth of population. There are many environmental
and human impacts which are caused by the careless of solid waste disposal. For
example: Air, soil and source of water at the damping site where the wastes are
disposed will be polluted due to the poor wastes management. Survey of daily
solid waste disposal is an important factor of best solid waste management that
everyone has to consider about.
II. Objective
The objective of this report is to estimate the average daily waste that a
person generates per day by collecting the data of daily solid waste disposal
during 32days.
III. Data collection
The solid waste that I have disposed in daily were recorded from 21st
October 2016 to 21st
November 2016. The collected solid wastes were separated
in two types: Organics (Food waste and Paper/Wooden) and Inorganics
(Aluminum cans and Plastic). This separation is aim to know the amount for each
type of waste that is present in total daily wastes.

These are many type of my daily solid waste disposal during 32 days:
IV. Results and Discussions
Follow the data in the above table, we can determine the total waste
generated in 32 days, the average daily waste and the percentage for each type of
waste as showed in table below.
Final Data Collection Food Waste Paper/Wooden Aluminum cans Plastics Total
Total Daily Weight (g) 10620 960 1370 1210 14160

The information in this table was taken to illustrate in the below 3D-pie
chart in order to make it easy for identifying the value for each waste composition.

The result obtained from this survey shows that the total average daily solid
waste that were generated by a person per day is approximately 443g. Moreover,
we found that the Food waste (75%) is the biggest component in the average daily
solid waste generation. This was followed by the Paper with an overall average
of 7%. For plastics wastes overall average of 8% and aluminum overall average
of 10%.
Since the food waste is the majority component in the daily waste disposal,
it is recommended that the food waste can take to create the compost which is so
rich in nutrients that it improves the fertility of the soil to make plants healthier.
On the other hand, the food waste can also generate the biogas which is a
renewable source and also environmental friendly. Moreover, the other waste like:
paper/wooden, plastic and aluminum cans are the materials that can be recycled.
Anyways, before throwing them away, we should reuse them as possible as we
can in order to reduce the environmental impacts from these materials.
V. Conclusion
In conclusion , this survey found that the daily disposed waste is about
443 g/person/day. Moreover, the percentage of each component in the daily
waste were also determined. This information is very useful for improving the
waste management in our country. Separate waste collection method should be
selected for solid waste management since it is an efficiency method. When the
wastes are separated, it is easy for recycling process. Therefore, the amount of
waste is also decreased before disposing into landfill. Hence, the separate waste
collection is best way to preserve and maintain natural resources to not only our
benefit but also future generation’s benefit.
