JSS 1: Recycling

Recycling is the process of collecting, processing, and converting waste materials into new useful products.

It involves reusing materials instead of throwing them away.

Examples:

I. Old newspapers can be recycled into new paper.

II. Used plastic bottles can be melted and made into new plastic items.

         Materials That Can Be Recycled

1. Paper (e.g., newspapers, cartons, books)

2. Glass (e.g., bottles, jars)

3. Metals (e.g., tin cans, aluminum)

4. Plastics (e.g., bottles, containers)

5. Fabrics (e.g., old clothes)

            Methods of Recycling

1. Mechanical Recycling

2. Chemical Recycling

3. Biological Recycling

            Mechanical Recycling

It involves melting or crushing materials to form new ones (e.g., plastic bottles → new containers).

            Chemical Recycling

It involves breaking down materials chemically (e.g., converting waste oil to fuel).

            Biological Recycling

It involves using natural processes to recycle organic waste (e.g., composting food waste)

            Processes of Recycling

Collection→Sorting→Cleaning→Processing→Manufacturing

1. Collection: Gathering waste materials from homes and industries.

2. Sorting: Separating different types of materials (plastic, metal, paper, etc.).

3. Cleaning: Washing and removing dirt or impurities.

4. Processing: Melting, pulping, or crushing materials for reuse.

5. Manufacturing: Producing new products from the processed materials.

                Importance of Recycling

1. Helps reduce waste in the environment.

2. Saves natural resources.

3. Reduces pollution and keeps the environment clean.

4. Saves energy used in producing new materials.

5. Creates job opportunities and income.
