Takeaways

• 😀 Hard waste materials are solid, difficult to reshape, and do not decompose easily.
• 😀 Hard waste is divided into two categories: organic and inorganic.
• 😀 Organic hard waste comes from living organisms, such as shells, bones, and wood.
• 😀 Inorganic hard waste includes materials like plastic, glass, and ceramics.
• 😀 Techniques for handling waste include reducing material use (Reduce), reusing items (Reuse), and recycling materials (Recycle).
• 😀 Organic waste can be recycled into compost or biogas, and used for sanitation processes.
• 😀 Inorganic waste, like plastic and glass, can be transformed into decorative or functional items.
• 😀 Recycled glass can be used for mosaics or as part of interior and exterior design.

Q & A

What is the definition of hard waste?

Hard waste refers to waste materials that are solid, rigid, and difficult to break down, shape, process, or decompose naturally. These materials can be either organic or inorganic.

What are the two main categories of hard waste?

The two main categories of hard waste are organic hard waste and inorganic hard waste. Organic hard waste comes from living organisms, while inorganic hard waste is man-made, such as plastics and ceramics.

What is the process for recycling organic hard waste?

Organic hard waste can be recycled in various ways, such as converting it into compost, creating biogas, or using it in sanitary landfills with proper waste management systems.

What methods are used to process hard waste?

The methods for processing hard waste include reducing or minimizing waste, reusing materials, and recycling. These methods aim to decrease the amount of waste produced and ensure sustainability.

Can all materials be recycled? What is the current trend in recycling?

Not all materials can be recycled, but there are growing industries that specialize in recycling waste into new products. For example, small industries and home businesses often transform waste materials into crafts or new goods.

Give examples of organic hard waste materials.

Examples of organic hard waste include seashells, fish scales, animal bones, coconut shells, and wood pieces.

What are examples of inorganic hard waste materials?

Examples of inorganic hard waste include broken glass, ceramics, plastics, and metals.

How can used glass be repurposed for crafts?

Used glass, especially colorful glass, can be turned into mosaic art or used to create decorative items that enhance interior or exterior design.

What is the process of cleaning and preparing seashells for crafting?

The process includes cleaning the shells to remove dirt and impurities, selecting strong shells that are not broken, soaking them in bleach, and then scrubbing off any remaining dirt. After drying under the sun, the shells can be used for various crafts.

How can plastic waste be transformed for crafting purposes?

Plastic waste, such as plastic bottles or straws, can be cleaned, dried, and cut into different shapes. It can then be used to make items like decorative ornaments, hanging pots, or even fashion accessories.
