Waste Management MCQ Quiz - Objective Question with Answer for Waste Management - Download Free PDF

The correct answer is Vegetable peels.

Key Points

• Vegetable peels are organic matter, which means they are derived from living organisms.
• Because they are organic, they can be broken down by biological processes like composting.
• In composting, microorganisms such as bacteria and fungi decompose vegetable peels into humus, a rich soil amendment.
• This process is part of the natural recycling of nutrients in the ecosystem.
• Using vegetable peels in compost helps reduce food waste and provides an environmentally friendly way to enrich soil.

 Additional Information

• Aluminium foil
  • Aluminium foil is a non-biodegradable material, meaning it cannot be broken down by biological processes.
  • It is made from aluminium, a metal that requires recycling processes different from composting.
• Milk packets
  • Milk packets are typically made of plastic, which is not biodegradable.
  • They require specialized recycling processes to be broken down.
• Plastic bottles
  • Plastic bottles are also non-biodegradable.
  • They are made from various types of plastics, such as PET, which can persist in the environment for hundreds of years.

The Correct answer is Biodegradable.

Key Points

• Biodegradable substances are those that can be broken down by natural processes involving microorganisms such as bacteria, fungi, and other biological means.
• These substances decompose into natural elements like water, carbon dioxide, and biomass, which do not harm the environment.
• Examples of biodegradable materials include food waste, paper, wood, and certain types of plastics designed to degrade naturally.
• Biodegradability is an important feature for reducing waste in landfills and minimizing environmental pollution.
• Using biodegradable materials helps in the conservation of resources and supports sustainable practices.

 Additional Information

• Non-biodegradable
  • Non-biodegradable substances cannot be broken down by natural processes. They persist in the environment for long periods.
  • Examples include most plastics, glass, and metals.
  • Non-biodegradable waste is a major contributor to environmental pollution and requires special disposal methods.
• Compostable
  • Compostable materials are a subset of biodegradable materials that break down under specific composting conditions to form nutrient-rich compost.
  • They require the right balance of temperature, moisture, and oxygen to decompose effectively.
  • Compostable items are often used to enrich soil and support plant growth.
• Recyclable
  • Recyclable materials can be processed and used to make new products, reducing the need for raw materials.
  • Common recyclable materials include paper, glass, metals, and certain plastics.
  • Recycling helps in reducing waste, conserving resources, and minimizing environmental impact.

Burning solid waste, a practice commonly known as open burning or incineration, is generally not recommended due to several environmental issues and health concerns.

Key Points Here are some of the key reasons why burning solid waste is discouraged:

• Air Pollution: The combustion of solid waste releases a variety of pollutants into the air, including particulate matter, dioxins, and other harmful chemicals. These pollutants can have detrimental effects on air quality and respiratory health.
• Toxic Emissions: Burning certain materials, especially plastics and other synthetic materials, can release toxic substances such as heavy metals and hazardous chemicals. These pollutants can pose serious health risks to both humans and the environment.
• Greenhouse Gas Emissions: Open burning contributes to the release of greenhouse gases, including carbon dioxide (CO2) and methane (CH4). These gases contribute to climate change and global warming.
• Odor and Nuisance: Burning waste can generate unpleasant odors and create a nuisance for nearby communities. This can negatively impact the quality of life for residents and businesses in the vicinity.
• Incomplete Combustion: Incomplete combustion of waste materials can result in the formation of soot, ash, and other residues. These residues may contain harmful substances and can contribute to soil and water pollution if not properly managed.
• Lack of Energy Recovery: Modern waste-to-energy technologies can convert solid waste into energy through controlled incineration, capturing the heat generated. However, open burning typically does not harness this energy, leading to a loss of potential resource recovery.
• Illegal Dumping: In some cases, burning waste may be used as a means of illegal disposal, contributing to environmental degradation and the spread of pollution.
• Impact on Human Health: The pollutants emitted during open burning can have adverse effects on human health, including respiratory problems, cardiovascular issues, and an increased risk of certain diseases.

Additional Information Given these environmental and health concerns, many countries and regions have implemented regulations to restrict or prohibit open burning of solid waste. Instead, waste management strategies focus on more sustainable practices such as recycling, composting, landfilling in controlled environments, and, where appropriate, advanced waste-to-energy technologies that capture energy while minimizing environmental impacts. Proper waste management is essential to protect the environment, conserve resources, and safeguard public health.

The correct answer is The integrated plan.

Key Points

• The integrated waste management plan focuses on the comprehensive management of waste through a combination of strategies like reduction, reuse, recycling, and safe disposal.
• It aims to minimize waste generation and maximize resource recovery by promoting sustainable waste practices.
• This approach incorporates segregation of waste at source, ensuring different types of waste (organic, recyclable, hazardous) are treated accordingly.
• The integrated plan ensures the involvement of various stakeholders, including government bodies, private sectors, and communities, to achieve effective waste management.
• It emphasizes compliance with environmental policies and regulations to reduce the ecological impact of waste disposal.

Additional Information

• Waste Hierarchy:
  • The waste hierarchy emphasizes the order of priority in waste management: reduce, reuse, recycle, recovery, and disposal.
  • Reduction and reuse are the most preferred methods, followed by recycling.
• Types of Waste:
  • Organic waste: Includes food and garden waste, which can be composted.
  • Recyclable waste: Includes plastics, metals, and paper that can be reprocessed into new materials.
  • Hazardous waste: Includes chemicals, batteries, and electronic waste that require special handling.
• Benefits of Integrated Waste Management:
  • Reduces environmental pollution and conserves natural resources.
  • Promotes sustainable development by ensuring the efficient use of materials.
  • Creates economic opportunities through recycling and recovery industries.
• Legislation and Policies:
  • In India, waste management is governed by laws like the Solid Waste Management Rules, 2016 and Plastic Waste Management Rules, 2016.
  • Global frameworks like the UN Sustainable Development Goals (SDG 12) promote responsible consumption and production, including waste management.
