This document provides a summary of the student's internship experience at SEANMITE GLOBAL LINK in Ogun State, Nigeria. It discusses the objectives of the Student Industrial Work Experience Scheme (SIWES) program, which aims to bridge the gap between theory and practical skills. The student's work involved learning about the recycling process, including collection, sorting, washing, shredding, identification of plastics, and extruding/compounding recycled materials. In conclusion, the student found the internship effective in applying theoretical knowledge to practical work and recommends improved facilitation of student placements and monitoring of the program.

2. ABSTRACT
This report briefly explain all activities carried out and
experiences gained during my internship programme at SEANMITE
GLOBAL LINK, OGUN STATE.

3. INTRODUCTION
The Students’ Industrial Work Experience Scheme (SIWES) was introduced
and designed as part of government policy to bridge the gap between theory
and practical knowledge of students in the Nigerian tertiary institutions.
Objectives of the program is:
 To prepare students for the work environment they are likely to meet after
graduation.
 To provide an avenue for students to acquire industrial skills and practical
experience.
 To instill in students an opportunity of applying their theoretical
knowledge in real work situation.

4. WORKDONE
RECYCLING PROCESS
Recycling, recovery and reprocessing of waste materials for use in new products. The
basic phases in recycling are the collection of waste materials, their processing or
manufacture into new products, and the purchase of those products, which may then
themselves be recycled. Typical materials that are recycled include iron and steel
scrap, aluminum cans, glass bottles, paper, wood, and plastics. The materials reused in
recycling serve as substitutes for raw materials obtained from such increasingly scarce
natural resources as petroleum, natural gas, coal, mineral ores, and trees. Recycling
can help reduce the quantities of solid waste deposited in landfills, which have become
increasingly expensive. Recycling also reduces the pollution of air, water, and land
resulting from waste disposal.
PROCESS INVOLVED IN RECYCLING
 collection / distribution
 Sorting/categorizing
 Cutting/shredding
 Indemnification / separation
 Extruding/compound

5. RECYCLING PROCESS EXPLAINED……..
COLLECTION + DISTRIBUTION
The first step in the mechanical recycling process is the collection of post-consumer
materials from homes, businesses, and institutions. This can be done by either local
government or private companies, with the latter often a popular option for
businesses.
Another option is taking plastics to communal collection points such as designated
recycling bins or facilities. This may be as simple as a bottle bank on a street corner or
as complex as a local waste site with large areas for various recyclable and non-
recyclable municipal solid waste (MSW).
SORTING + CATEGORIZING
The next step in the plastic recycling process is sorting. There are several different
types of plastic (see below), which need to be separated from each other by recyclers.
Further to that, plastics might be sorted by other properties such as color, thickness,
and use. This is done by machines at the recycling plant and is an important step to
increase the efficiency of plants and avoid the contamination of end products.

6. RECYCLING PROCESS EXPLAINED……..
WASHING
Washing is a crucial step in the plastic recycling process since it removes some of the
impurities that can impede the operation, or completely ruin a batch of recycled
plastic. The impurities targeted in this step commonly include things such as product
labels and adhesives as well as dirt and food residue. While plastic is often washed at
this stage, it is important to remember that this doesn’t take away from the
importance of ensuring plastics are as free from impurities as possible before disposal
and collection.
SHREDDING
The plastic is then fed into shredders, which break it down into much smaller pieces.
These smaller pieces, unlike formed plastic products, can be processed in the next
stages for reuse. Additionally, the resized plastic pieces can be used for other
applications without further processing, such as an additive within asphalt or simply
sold as a raw material.
Breaking down the plastic into smaller pieces also allows for any remaining impurities
to be found. This is especially true of contaminants such as metal, which may not have
been removed by washing but can be easily collected with a magnet at this stage.

7. RECYCLING PROCESS EXPLAINED……..
IDENTIFICATION AND SEPARATION OF PLASTICS
Here, the plastic pieces are tested for their class and quality. First, they are segregated
based on density, which is tested by floating the particles of plastic in a container of
water. This is followed by a test for what is known as the “air classification”, which
determines the thickness of the plastic pieces. It is done by placing the shredded
plastic into a wind tunnel, with thinner pieces floating while larger/thicker pieces stay
at the bottom.
EXTRUDING + COMPOUNDING
This final plastic recycling process step is where the particles of shredded plastic are
transformed into a usable product for manufactures. The shredded plastic is melted
and crushed together to form pellets. It is worth noting that it is not always possible to
compound all types, classification, and qualities of plastic at a single plant, so different
grades of plastic are sometimes sent to other recycling facilities for this final step.

8. CONCLUSION & RECOMMENDATIONS
CONCLUSION
The concept of the Student Industrial Work Experience Scheme is with the sole
objective to bridge the gap between the theoretical knowledge amassed in class and
its practical application on field, has been no doubt ultimately effective on my part.
The exposure to the field applications and importance of these practical activities was
overwhelming.
RECOMMENDATIONS
• The university should facilitate the getting of placement by the I.T. students to ensure early
industrial attachment.
• ITF should ensure the regular visitation of the ITF officers to Supervising Agencies
• Institutions, employers and students on attachment.
• The SIWES coordinators, ITF agencies, and area office should ensure regular vetting of
students’ log books.
