Instructions: Choose the best answer for each question.
1. Which of the following is NOT an environmental impact of food waste?
a) Increased landfill volume
This is a direct impact of food waste.
While food waste can contribute to habitat loss, it's not a primary direct impact.
Food waste decomposition releases methane, a powerful greenhouse gas.
Leachate from landfills contaminates water sources.
2. How does food waste affect wastewater treatment systems?
a) Decreases the organic load in wastewater
Food waste actually increases the organic load, requiring more treatment.
Food waste increases the oxygen demand for breakdown of organic matter.
This is a significant consequence of food waste in wastewater.
Food waste actually leads to increased sludge production.
3. Which of the following is NOT a solution to manage food waste?
a) Source reduction through mindful consumption
This is a crucial step in reducing food waste.
Composting is a sustainable way to manage food waste.
While burning can produce energy, it's not a sustainable solution due to potential air pollution.
Anaerobic digestion is a valuable method for managing food waste.
4. What is the role of wastewater treatment optimization in managing food waste?
a) Eliminating the need for composting and anaerobic digestion
Wastewater treatment alone can't replace other waste management methods.
Advanced treatment technologies can effectively handle the impact of food waste.
This is typically achieved through anaerobic digestion, not wastewater treatment alone.
Wastewater treatment addresses the consequences, not the source of the problem.
5. Why is it important to address food waste in the context of environmental and water treatment?
a) Food waste contributes to climate change and water pollution
Food waste has significant environmental and water quality impacts.
Food waste is a growing and serious global concern.
The environmental and water treatment impacts are crucial to consider.
Food waste is a global problem, affecting both developed and developing countries.
Scenario:
A local restaurant generates approximately 50 kg of food waste daily. Currently, they dispose of it in a landfill.
Task:
Possible solutions and considerations:
Recommended Solution:
Based on the scenario, a combination of composting and food waste collection services could be ideal:
Justification:
This approach combines the benefits of both methods – easy composting for smaller amounts and professional management for larger volumes, optimizing cost and resource utilization.
