Garbage in Garbage out

Our Objective

To generate awareness amongst students on the topic of waste management.


The Theory


Scrap is made up of recyclable materials, most often metals, that are left over after a product is manufactured and consumed. Examples of scrap include automotive parts, building materials, and extra materials. In contrast to waste, recovered metals are worth money, and non-metallic items are also recovered for recycling. After being gathered, the materials are divided into different types; normally, metal scrap will be processed mechanically before being crushed, shredded, and sorted. 

Recycling scrap is crucial for developing a sustainable economy or a circular economy since it consumes much less energy and has a far less negative impact on the environment than mining metal ore. Metal recycling is a significant industrial operation with intricate networks of wrecking yards, sorting facilities, and recycling plants. This is especially true of structural steel, ships, and used manufactured items, such as cars and white goods. 



Waste materials are recycled, recovered, and reprocessed to be used in new goods. The fundamental steps in recycling are waste material collection, its processing or production into new products, and the purchase of those products, which may subsequently be recycled themselves. Iron and steel waste, aluminium cans, glass bottles, paper, wood, and plastics are examples of materials that are frequently recycled.  

The recycled materials act as replacements for raw materials derived from increasingly depleted natural resources like oil, gas, coal, mineral ores, and forests. Recycling can aid in lowering the amount of solid waste dumped in landfills, which are becoming more expensive. Recycling also lessens the pollution of the air, water, and land caused by the dumping of garbage. 


Benefits of Recycling

  • Energy savings of 75%. 
  • 90% of the raw materials utilised are saved. 
  • Reduction in air pollution by 86%. 
  • 40% less water is used. 
  • Reduction in water pollution by 76%. 
  • Reduction of mining wastes by 97%. 


Learning Outcomes 

  • Students can understand about scrap. 
  • Students can understand more about recycling. 
  • Students come to know about the benefits of recycling.
