Sustainable Engineering: Building a Flashlight from Waste Bottles

This project log documents the process of building a flashlight using recycled plastic bottles. The project schedule, background research on environmental pollution, and the importance of ecologically acceptable products are discussed. The log details the selection of the flashlight project for its simplicity, ecological benefits, and use of reused materials. It outlines the project's objectives, including designing and producing a flashlight from recycled materials, assessing its functionality, and conducting a cost analysis. The log covers the risk assessment, component acquisition (plastic bottles, scissors, LED light, wires, batteries), and the step-by-step manufacturing process, from cutting and shaping the bottle to assembling the circuit and testing the final product. The project concludes with a cost exploration, final testing, and a presentation, highlighting the successful achievement of the project's objectives. Desklib offers a range of similar projects and solved assignments for students.

Week 1
In the course of week 1 the opening research work was executed where the leading goal was to
comprehend the significance of ecologically acceptable merchandises.
2

The background study was carried out to realize the dangers to environs from engineering
products.
How engineering merchandises are causing the environment pollution and how it can be
protected? The only explanation is to develop ecologically acceptable products.
A number of statistical data was collected to demonstrate how urgently it is essential to
produce ecologically acceptable products, for instance
Pollution is highly hazardous distressing over one hundred million people all over the world and
most of the pollutants emanate from industrial and automobile emissions. People living in more
contaminated regions such as areas nearer to industrial center are more predisposed to
perilous diseases. One exploration display that people living in polluted regions have 20 % more
risk to contract lung cancer that eventually kills the patient. However, people living in clean
areas are safe (dosomething.org).
Week 2
In the course of week 2 research work was carried out to find a product that can be prepared
using reused material.
The product ought to be made from reused ingredients so that materials can be stopped from
wastages and can be recycled even when they are no more essential.
An online research was conducted and studied to find out a product that can be more
appropriate and can provide chances to learn new things.
3

The key purpose was to
 Find a modest product
 It must be ecologically acceptable
 It ought to be stress-free to produce
 The task should be practical
 It should be prepared from reused material
 It should be cost-effective
After a long research work a flash light prepared from reused material was carefully chosen and
the key motive was that it was simple to create and it comprised of simple engineering
concepts.
Week 3
In the course of week 3 the contextual studies continued to discover important statistics and
data that can be incorporated in the assignment report.
After confirming the title, the next step was to comprehend the elementary functioning of the
merchandise and to find out stress-free means to prepare it.
The key objectives of the task were also well-defined throughout week 3 and they are given as
 Design a flash light that can be produced using reused constituents
 Production of the flashlight using the projected constituent
 Assessment of the final produce for its appropriate working
4

 Carry out cost exploration to guarantee the product is feasible and can contest in the
business market
The risk assessment was also executed in week 3 to guarantee that the task is safe carry out
and it does not consist of any risks to employees and investigators in the lab. This task is
harmless due to subsequent reasons
 The task only encompasses simple constituents that are harmless
 The constituents will be obtained from reused material and are harmless
 No hazardous or combustible chemicals to be used
 No heavy weight lifting is included, so safe
Week 4
After finalizing the goals and aims the next phase was to commence executing the work on
project and in this week the basic diagrams were drawn to conclude the design of the project.
Week 5
Week 5 was eventful since the main activities carried out in this week were completing
drawings, main constituents acquired and commenced manufacturing and amassing
components.
5

A list of components is given here
 A plastic water bottle
 A pair of scissors
 A craft knife
 A metal hacksaw
 A hot glue gun
 A handful of
 Pliers
 2 feet of 22 gauge wire
 2 Cells
 LED light
 A big cap
Week 6
The modules were amassed from week 6 to week 11 and in the meantime the task also
progressed on the report writing and log book writing.
Week 7, 8 and 9
Beginning with the plastic bottle, the bottle was chopped into pieces as necessary.
Safety measurements ought to be taken since the knife is sharp and it can certainly injure the
hand.
As shown below, the bottle was cut into shape as required.
6

Two bottles were essential as two bottle heads were required
Then, one head is linked with other front part of bottle with stick as shown above.
7

Two bottle heads can be seen above.
Week 10 and 11
The flashlight body was prepared using Popsicle sticks
Then the battery was embedded, circuited end first in the toilet paper roll.
8

The second battery is then inserted and the positive side that is already inside will meet the
negative side.
Then one bulb was taped on the head on the battery by ensuring that the bottom half is visible.
The final product can be seen in the following figure.

Week 12
The project was finalized in first 10 weeks and the residual time was consumed on writing the
final report, and preparing for project presentation. The log book was written as the task
progressed. In week 12 the cost exploration was also carried out and it is delivered in the final
report.
Week 13
In the final week of project the set up was provided and tested and the reports were finalized.
The task presentation was carried out according to feedback, the future recommendations
were also considered. Overall the project went very well and the required objectives were met
with good standard and expectations.
