Waste Management and Recycling starts at 11 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Waste Management and Recycling.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 11
Describe one chemical process that occurs during the incineration of municipal solid waste.
Describe one way in which improper waste management can affect human health.
Describe the chemical risks associated with the improper disposal of batteries.
Describe the environmental benefits of using recycled paper instead of virgin paper.
Describe the process of leachate formation in landfills and its environmental impact.
Explain the difference between biodegradable and non-biodegradable waste.
Explain the environmental impact of open dumping of waste.
Explain the role of microorganisms in the composting process.
Explain the term 'leachate' and its significance in landfill management.
Explain why hazardous waste requires special handling and disposal methods.
Explain why plastics are considered non-biodegradable.
Name two environmental problems caused by improper waste disposal.
State one chemical hazard associated with improper disposal of electronic waste (e-waste).
What is the main chemical process involved in composting?
Which method of waste management involves burning waste at high temperatures?
A landfill is found to be releasing significant amounts of methane gas. Explain the chemical process responsible for this and discuss one method to mitigate its environmental impact.
A recycling facility receives a batch of plastic waste containing both PET (polyethylene terephthalate) and PVC (polyvinyl chloride). Describe the chemical reason why these two plastics must be separated before recycling and the potential consequences if they are not.
Context: A city is considering two waste management strategies: (A) increasing landfill capacity, and (B) investing in advanced recycling technologies that use chemical processes to break down plastics into monomers for reuse.
Question: Discuss the long-term environmental and chemical advantages of strategy B over strategy A.
During the recycling of paper, why is it important to remove inks and dyes, and what chemical process is commonly used for this purpose?
Explain how the concept of 'closed-loop recycling' differs from 'open-loop recycling' in terms of chemical processes and environmental impact.
