It compresses light tin cans using a Hydraulic Press, then directs them to a weighing scale at the back for quick measurement, and pushes them to the exit. The prototype has a pure metal body and internal parts to support the device while in process. Recycling is a good thing. It turns used materials into new products to reduce waste. Small recyclers, called junk shops, make a living by gathering and selling recyclables, such as scrap metals, plastic bottles, and electronics, to a recycling facility. These producers then turn the materials into raw goods for new products. Manually flattening scraps is one of the problems junk collectors deal with. The researchers surveyed Caloocan's trash business owners and collectors to gather insights and data. The survey highlighted issues and limitations, particularly in collecting tin cans. In response, they designed and built a trash compressor prototype. The compressor makes flattening tin cans easier for recyclers and includes a weighing feature to quickly assess the value of accumulated tin cans. The fabrication of the frame and body lasted 3 months before tests were conducted and evaluated. To determine the prototype's capabilities, a quantitative approach survey questionnaires were answered by 35 respondents. Furthermore, the review's findings show that the trash compressing prototype is also easy to operate and aesthetically pleasing. The device scored well overall, with a mean of 3.77 for performance and 3.84 for workability, showcasing waste reduction and space use efficiency. Durability 3.63 and safety 3.76 were rated iv positively, though concerns about heavy-duty use remain. Its economic viability, 3.48, suggests potential for widespread adoption in recycling.

The Trash Compressor for Light Metal Scraps with Weighing Scale is a manual
device for Community Junk Shops. It compresses light tin cans using a Hydraulic
Press, then directs them to a weighing scale at the back for quick measurement,
and pushes them to the exit. The prototype has a pure metal body and internal
parts to support the device while in process. Recycling is a good thing. It turns
used materials into new products to reduce waste. Small recyclers, called junk
shops, make a living by gathering and selling recyclables, such as scrap metals,
plastic bottles, and electronics, to a recycling facility. These producers then turn
the materials into raw goods for new products. Manually flattening scraps is one
of the problems junk collectors deal with. The researchers surveyed Caloocan's
trash business owners and collectors to gather insights and data. The survey
highlighted issues and limitations, particularly in collecting tin cans. In response,
they designed and built a trash compressor prototype. The compressor makes
flattening tin cans easier for recyclers and includes a weighing feature to quickly
assess the value of accumulated tin cans. The fabrication of the frame and body
lasted 3 months before tests were conducted and evaluated. To determine the
prototype's capabilities, a quantitative approach survey questionnaires were
answered by 35 respondents.
Furthermore, the review's findings show that the trash compressing prototype is
also easy to operate and aesthetically pleasing. The device scored well overall,
with a mean of 3.77 for performance and 3.84 for workability, showcasing waste
reduction and space use efficiency. Durability 3.63 and safety 3.76 were rated
