Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

To measure the effectiveness of waste reduction programs, schools can track waste generation over time, compare data to previous years or benchmarks, and conduct waste audits to analyze the composition of waste, providing valuable insights for improvement.

Multiple choice

Which of the following is NOT a sustainable waste management practice in schools?

  1. Composting organic waste

  2. Recycling paper, plastic, and metal

  3. Incinerating waste on school grounds

  4. Donating reusable items to local charities
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Incinerating waste on school grounds is not a sustainable practice as it releases harmful pollutants into the air, contributing to air pollution and posing health risks to the school community.

Multiple choice

What is the ultimate goal of sustainable school programs in terms of waste management?

  1. Eliminating all waste generated by the school

  2. Reducing waste to the lowest possible level

  3. Recycling and composting all waste generated by the school

  4. Educating students about waste reduction and sustainability
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

While eliminating all waste may not be entirely feasible, the ultimate goal of sustainable school programs in terms of waste management is to reduce waste generation to the lowest possible level, promoting resource conservation and minimizing the school's environmental impact.

Multiple choice

Which of the following is NOT considered e-waste?

  1. Mobile phones

  2. Televisions

  3. Plastic bags

  4. Computers
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Plastic bags are not considered e-waste as they do not contain electronic components.

Multiple choice

Which of the following is NOT a common method for recycling electronics?

  1. Mechanical separation

  2. Chemical treatment

  3. Incineration

  4. Pyrolysis
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Incineration is not a common method for recycling electronics as it releases harmful pollutants into the environment.

Multiple choice

Which of the following is NOT a characteristic of hazardous waste under RCRA?

  1. Ignitability

  2. Corrosivity

  3. Reactivity

  4. Toxicity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Toxicity is not a characteristic of hazardous waste under RCRA. The four characteristics of hazardous waste under RCRA are ignitability, corrosivity, reactivity, and toxicity.

Multiple choice

Which of the following is NOT a method used to characterize hazardous waste?

  1. Laboratory analysis

  2. Field testing

  3. Process knowledge

  4. Material Safety Data Sheets (MSDSs)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Material Safety Data Sheets (MSDSs) are not used to characterize hazardous waste. MSDSs provide information on the hazards of a chemical product, but they do not provide the data necessary to classify a waste as hazardous.

Multiple choice

Which of the following is NOT a benefit of waste minimization?

  1. Reduces the cost of hazardous waste disposal.

  2. Protects human health and the environment.

  3. Conserves natural resources.

  4. Increases the amount of hazardous waste generated.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Waste minimization does not increase the amount of hazardous waste generated. It reduces the amount of hazardous waste generated by reducing the amount of waste produced and by recycling and reusing materials.

Multiple choice

Which of the following is NOT a method of waste treatment?

  1. Incineration

  2. Landfilling

  3. Recycling

  4. Biological treatment
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Landfilling is not a method of waste treatment. Landfilling is the process of disposing of waste by burying it in the ground. It does not treat the waste to make it less hazardous.

Multiple choice
