Making new containers from crushed glass helps to...
Correct Answer
D. Both A and B
Explanation
Making new containers from crushed glass helps to save materials and save fuel. By recycling glass, we can reduce the need for raw materials such as sand, soda ash, and limestone, which are used in the production of new glass. This conserves natural resources and reduces the environmental impact of extracting and processing these materials. Additionally, recycling glass requires less energy compared to producing new glass from raw materials, leading to fuel savings and a decrease in greenhouse gas emissions. Therefore, both options A and B are correct.
2.
Which of the following cannot be recycled?
Correct Answer
D. False. All the above can be recycled
Explanation
The given answer states that all the options can be recycled, which means that none of them cannot be recycled. However, this contradicts the question, which asks for the option that cannot be recycled. Therefore, the given answer is incorrect.
3.
Can you name the plastic from the SPI resin identification code?
Correct Answer
A. OTHER
Explanation
The plastic identified as "OTHER" in the SPI resin identification code refers to any plastic that does not fall under the categories of PVC/Vinyl, LDPE, or PP. This category is used for plastic materials that do not have a specific code assigned to them, or for plastics that are made from a combination of different materials.
4.
Glass can be recycled without alteration...
Correct Answer
D. Continuously
Explanation
Glass can be recycled continuously without alteration. Unlike other materials, glass does not degrade during the recycling process. It can be melted down and reshaped repeatedly without losing its quality or purity. This makes glass a highly sustainable and environmentally friendly material, as it can be reused indefinitely without the need for new raw materials.
5.
FACT: Enough plastic is thrown away each year to circle the Earth…
Correct Answer
D. 4 times
Explanation
Enough plastic is thrown away each year to circle the Earth 4 times. This means that the amount of plastic waste generated annually is sufficient to create a circular loop around the Earth's circumference four times. This highlights the alarming and excessive amount of plastic being discarded, emphasizing the urgent need for effective waste management and reduction strategies to combat the environmental impact of plastic pollution.
6.
Donating is an example of
Correct Answer
B. Reusing
Explanation
Donating is an example of reusing because when we donate something, we are giving it to someone else who can use it again. Instead of throwing it away or buying a new item, donating allows the item to be reused by someone else, extending its lifespan and reducing waste.
7.
Composting is achieved through recycling...
Correct Answer
C. Organic waste
Explanation
Composting is achieved through recycling organic waste. Organic waste, such as food scraps, yard trimmings, and plant materials, can be decomposed naturally through a process called composting. This process involves creating an environment that promotes the breakdown of organic matter by microorganisms, resulting in nutrient-rich compost that can be used as a natural fertilizer for plants. Composting helps divert organic waste from landfills, reduces greenhouse gas emissions, and promotes sustainable waste management practices.
8.
How many trees will be saved by recycling 1 ton of paper?
Correct Answer
C. 17 trees
Explanation
Recycling 1 ton of paper can save approximately 17 trees. This is because when paper is recycled, it reduces the need for new paper production, which in turn reduces the number of trees that need to be cut down for paper manufacturing. By recycling, we can conserve natural resources and protect the environment by minimizing deforestation.
9.
Which type of plastic is friendlier to the environment?
Correct Answer
D. PETE / PET
Explanation
PETE/PET (polyethylene terephthalate) is friendlier to the environment compared to the other options listed. PETE/PET is a widely recycled plastic that can be reused to make new products such as bottles, containers, and polyester fibers. It is also lightweight, which reduces transportation emissions. Additionally, PETE/PET has a lower carbon footprint and energy consumption compared to other plastics. Overall, PETE/PET is considered more environmentally friendly due to its recyclability and lower environmental impact.
10.
Which one of the following takes the most to dissolve in nature?
Correct Answer
C. A bottle of glass
Explanation
Glass is made from silica, which is a naturally occurring compound. It is chemically stable and does not easily dissolve in nature. On the other hand, a bus ticket, plastic bottle, and woolen cloth are made from materials that can degrade or dissolve over time when exposed to environmental factors such as moisture, heat, or microorganisms. Therefore, out of the given options, a bottle of glass takes the most time to dissolve in nature.
