Waste recycling generally follows four main steps to convert waste into reusable materials.
1. Collection & Sorting
Purpose: Gather and separate different types of waste.
Process:
o Waste is collected from homes, businesses, and industries.
o Items are sorted into categories: plastic, paper, glass, metal, organic waste, and
e-waste.
o Sorting happens manually or through machines at recycling facilities.
2. Processing & Cleaning
Purpose: Prepare materials for recycling by cleaning and breaking them down.
Process:
o Contaminants (food residues, labels, non-recyclable materials) are removed.
o Waste is shredded, crushed, or melted depending on the material type.
3. Conversion into New Materials
Purpose: Transform waste into raw materials for new products.
Process:
o Plastic is melted and remolded.
o Paper is pulped, cleaned, and reprocessed.
o Glass is crushed, melted, and reshaped.
o Metal is melted and reformed into new items.
4. New Product Manufacturing & Reuse
Purpose: Use recycled materials to create new products and distribute them.
Process:
o Factories use processed materials to manufacture new goods.
o Products made from recycled materials (e.g., bottles, clothes, packaging) are sold
and reused.
