Question

What do we call an object that can be processed so that it can be used again? A) trash C) disposable B) recyclable D) hazardous

Short answer

The correct answer is: B) recyclable.

Step-by-step solution

Understanding the Question

The question asks for a term that describes an object which, through some process, can be used again. Consider the definitions or common uses of the given options to identify the correct term.

Analyzing the Options

Let's review each option: - **Trash**: This is waste material or items meant to be discarded. It's not intended for reuse although some trash may be recycled. - **Disposable**: Items that are designed for single use and are typically thrown away after use. - **Recyclable**: Refers to materials that can be collected, processed, and reconstituted for use in new products. - **Hazardous**: Refers to waste that poses substantial threats to public health or the environment when improperly managed.

Identifying the Correct Term

Based on the analysis, identify that the term "recyclable" fits the description of an object that can be processed and used again. Recyclable materials can be collected and transformed into new products, thereby extending their life and utility.

Key concepts

Recyclable Materials

Recyclable materials are substances that can be processed and reused in the creation of new products. These are essential for sustainable living as they help reduce waste and conserve natural resources. Common examples include:

• Paper and cardboard
• Glass bottles and jars
• Plastic containers and bottles
• Metal cans, like aluminum

Recycling processes involve collecting these materials, sorting them, and then breaking them down into raw forms. This allows them to be re-manufactured into new items, saving energy and reducing pollution. For example, recycling aluminum cans saves up to 95% of the energy required to produce new aluminum from raw ore. By understanding what materials are recyclable, individuals and communities can contribute positively to the environment.

Waste Management

Waste management is the process of handling waste from its creation to its final disposal. This includes collection, transport, treatment, and disposal. Efficient waste management ensures environmental protection by reducing the adverse effects of waste. Key strategies in waste management are:

• Reducing: Minimizing waste generation at its source.
• Reusing: Finding new ways to use items instead of discarding them.
• Recycling: Converting waste materials into new products.

Effective waste management practices are integral to maintaining clean and healthy communities. Innovations in waste management, such as advanced recycling technologies and composting, help in converting potential waste into useful materials and energy sources, thus enhancing sustainability.

Environmental Science

Environmental science is a multidisciplinary field that studies the interactions between humans and the environment. It encompasses various areas such as ecology, biology, meteorology, and chemistry. A central goal of environmental science is to understand how natural systems function and how human activities affect these systems. Key topics include:

• Climate change and global warming
• Pollution and waste management
• Biodiversity and conservation

By applying scientific principles and methodologies, environmental scientists aim to develop sustainable solutions to environmental problems. Recycling is one such solution, as it addresses waste management challenges by reducing landfill usage and conserving resources. Through recycling efforts, this field aims to foster a more sustainable interaction between humanity and the natural world.
